Answer:

We need the tables for this answer??

Answer:

Step-by-step explanation:

As we know,

Complementary angles:

The angles whose sum results to 90° are known as the complementary angles.

So,

46° + (5x - 1)° = 90°

=> 46 + 5x - 1 = 90

=> 45 + 5x = 90

=> 45 + 5x - 45 = 90 - 45

=> 5x = 45

[tex] = > \frac{5x}{5} = \frac{45}{5} [/tex]

=> x = 9

Hence, required value of x = 9 (Ans)

Answer:

Step-by-step explanation:

We know that:

Solution:

Removal of brackets:

Subtracting 45 from both sides:

Solving:

Hence, the value of x is 9.

Answer:

Let's work to solve this system of equations:

y = 2x ~~~~~~~~\gray{\text{Equation 1}}y=2x        Equation 1y, equals, 2, x, space, space, space, space, space, space, space, space, start color gray, start text, E, q, u, a, t, i, o, n, space, 1, end text, end color gray

x + y = 24 ~~~~~~~~\gray{\text{Equation 2}}x+y=24        Equation 2x, plus, y, equals, 24, space, space, space, space, space, space, space, space, start color gray, start text, E, q, u, a, t, i, o, n, space, 2, end text, end color gray

The tricky thing is that there are two variables, xxx and yyy. If only we could get rid of one of the variables...

Here's an idea! Equation 111 tells us that \goldD{2x}2xstart color #e07d10, 2, x, end color #e07d10 and \goldD yystart color #e07d10, y, end color #e07d10 are equal. So let's plug in \goldD{2x}2xstart color #e07d10, 2, x, end color #e07d10 for \goldD yystart color #e07d10, y, end color #e07d10 in Equation 222 to get rid of the yyy variable in that equation:

\begin{aligned} x + \goldD y &= 24 &\gray{\text{Equation 2}} \\\\ x + \goldD{2x} &= 24 &\gray{\text{Substitute 2x for y}}\end{aligned}

x+y

x+2x

​

=24

=24

​

Equation 2

Substitute 2x for y

​

Brilliant! Now we have an equation with just the xxx variable that we know how to solve:

x+2x3x 3x3x=24=24=243=8Divide each side by 3

Nice! So we know that xxx equals 888. But remember that we are looking for an ordered pair. We need a yyy value as well. Let's use the first equation to find yyy when xxx equals 888:

\begin{aligned} y &= 2\blueD x &\gray{\text{Equation 1}} \\\\ y &= 2(\blueD8) &\gray{\text{Substitute 8 for x}}\\\\ \greenD y &\greenD= \greenD{16}\end{aligned}

y

y

y

​

=2x

=2(8)

=16

​

Equation 1

Substitute 8 for x

​

Sweet! So the solution to the system of equations is (\blueD8, \greenD{16})(8,16)left parenthesis, start color #11accd, 8, end color #11accd, comma, start color #1fab54, 16, end color #1fab54, right parenthesis. It's always a good idea to check the solution back in the original equations just to be sure.

Let's check the first equation:

\begin{aligned} y &= 2x \\\\ \greenD{16} &\stackrel?= 2(\blueD{8}) &\gray{\text{Plug in x = 8 and y = 16}}\\\\ 16 &= 16 &\gray{\text{Yes!}}\end{aligned}

y

16

16

​

=2x

2(8)

=16

​

Plug in x = 8 and y = 16

Yes!

​

Let's check the second equation:

\begin{aligned} x +y &= 24 \\\\ \blueD{8} + \greenD{16} &\stackrel?= 24 &\gray{\text{Plug in x = 8 and y = 16}}\\\\ 24 &= 24 &\gray{\text{Yes!}}\end{aligned}

x+y

8+16

24

​

=24

=

?

24

=24

​

Plug in x = 8 and y = 16

Yes!

​

Great! (\blueD8, \greenD{16})(8,16)left parenthesis, start color #11accd, 8, end color #11accd, comma, start color #1fab54, 16, end color #1fab54, right parenthesis is indeed a solution. We must not have made any mistakes.

Your turn to solve a system of equations using substitution.

Use substitution to solve the following system of equations.

4x + y = 284x+y=284, x, plus, y, equals, 28

y = 3xy=3xy, equals, 3, x

x =x=x, equals

y =y=y, equals

[Show solution]

Solving for a variable first, then using substitution

Sometimes using substitution is a little bit trickier. Here's another system of equations:

-3x + y = -9~~~~~~~ \gray{\text{Equation 1}}−3x+y=−9       Equation 1minus, 3, x, plus, y, equals, minus, 9, space, space, space, space, space, space, space, start color gray, start text, E, q, u, a, t, i, o, n, space, 1, end text, end color gray

5x + 4y = 32~~~~~~~ \gray{\text{Equation 2}}5x+4y=32       Equation 25, x, plus, 4, y, equals, 32, space, space, space, space, space, space, space, start color gray, start text, E, q, u, a, t, i, o, n, space, 2, end text, end color gray

Notice that neither of these equations are already solved for xxx or yyy. As a result, the first step is to solve for xxx or yyy first. Here's how it goes:

Step 1: Solve one of the equations for one of the variables.

Let's solve the first equation for yyy:

\begin{aligned} -3x + y &= -9 &\gray{\text{Equation 1}} \\\\ -3x + y + \maroonD{3x} &= -9 +\maroonD{3x} &\gray{\text{Add 3x to each side}} \\\\ y &= {-9 +3x} &\gray{\text{}}\end{aligned}

−3x+y

−3x+y+3x

y

​

=−9

=−9+3x

=−9+3x

​

Equation 1

Add 3x to each side

​

Step 2: Substitute that equation into the other equation, and solve for xxx.

\begin{aligned} 5x + 4\goldD y &= 32 &\gray{\text{Equation 2}} \\\\ 5x +4(\goldD{-9 + 3x}) &= 32 &\gray{\text{Substitute -9 + 3x for y}} \\\\ 5x -36 +12x &= 32 &\gray{\text{}} \\\\ 17x - 36 &= 32 &\gray{\text{}} \\\\ 17x &= 68 &\gray{\text{}} \\\\ \blueD x &\blueD= \blueD4 &\gray{\text{Divide each side by 17}}\end{aligned}

5x+4y

5x+4(−9+3x)

5x−36+12x

17x−36

17x

x

​

=32

=32

=32

=32

=68

=4

​

Equation 2

Substitute -9 + 3x for y

Divide each side by 17

​

Step 3: Substitute x = 4x=4x, equals, 4 into one of the original equations, and solve for yyy.

\begin{aligned} -3\blueD x + y &= -9 &\gray{\text{The first equation}} \\\\ -3(\blueD{4}) +y &= -9 &\gray{\text{Substitute 4 for x}} \\\\ -12 + y &= -9 &\gray{\text{}} \\\\ \greenD y &\greenD= \greenD3 &\gray{\text{Add 12 to each side}} \end{aligned}

Answer: -2

Step-by-step explanation:

(-4+-3) -(2-7)

-7 - -5

-7+5= -2

Answer:

Step-by-step explanation:

(-4)  & (-3) have same sign ( -ve) . So add and put the (-) sign for the result.

2 is a positive number and (-7) is a negative number. Subtract and put the sign of the bigger number for the result.

(-4 + (-3) ) - (2 - 7) = -7 - (-5)

                           = - 7 + 5

                            = -2

Answer:

what are the answer choices

Step-by-step explanation:

Answer:

The solution is (1, -1)

Step-by-step explanation:

Rearrange the first equation so it is in standard form just like the second equation. To do this, subtract y from both sides.

5x = y + 6

-y     -y

rewrite the equations

5x - y = 6

5x + 2y = 3

You have two choices of which variable ( x or y) you can eliminate. Regardless of choice you have to multiply one of the equations by a number. What you really want to look for is a set of twins, meaning you have the same number and the same variable. Also one has to be negative and one has to be positive. Both equations have a 5x, so I need to make one negative by multiplying the entire equation by -1. I'll do that with the top equation. This just changes the signs of each term.

-1(5x - y = 6)

-5x + y = -6

5x + 2y = 3

Add the two equations and solve for y. The -5x and 5x will now be eliminated. Remember there is a 1 in front of the y.

3y = -3

3y/3 = -3/3

y = -1

Now solve for x. Pick either of the original equations to substitute in for y. I'm going to pick the first one.

5x = y + 6

5x = -1 + 6

5x = 5

5x/5 = 5/5

x = 1

The solution is (1, -1)

Answer:

y = -1/8x - 2

Step-by-step explanation:

y-intercept of -2 means (0,-2)

Given (0,-2) and (8,-3)

Slope m = (y2-y1)/(x2-x1)

m = (-3 - -2)/(8 - 0) = -1/8

Using (8,-3)

y = mx + b

-3 = -1/8(8) + b

-3 = -1 + b

b = -2

then y = -1/8x - 2

The area of the triangle is 2376 square inches

The area of a shape is the amount of space occupied by the shape

Given the three sides of the triangle, the area of the triangle is calculated using:

[tex]Area = \sqrt{s(s- a)(s -b)(s - c)}[/tex]

Where s represents the semi-perimeter, and it is calculated using

[tex]s = \frac{a + b + c}{2}[/tex]

In this case, we have:

[tex]s = \frac{66 + 98 + 72}{2}[/tex]

[tex]s = \frac{236}{2}[/tex]

[tex]s = 118[/tex]

Recall that:

[tex]Area = \sqrt{s(s- a)(s -b)(s - c)}[/tex]

So, we have:

[tex]Area = \sqrt{118 \times (118 - 66) \times (118 - 98) \times (118 - 72)}[/tex]

[tex]Area = \sqrt{5645120}[/tex]

Evaluate the root

[tex]Area = 2376[/tex]

Hence, the area of the triangle is 2376 square inches

The midpoint is (1, 4.5)

Step-by-step explanation:

To find the midpoint, take the coordinates for the two endpoints and add the x's and divide by two. Then add the y's and divide by two. R has coordinates (-4,0) and B is (6,9). On this particular question when we just do half of the problem we can pick out the correct answer from the multiple choice list. -4 + 6 is 2. And divided by 2 is

Answer:

Step-by-step explanation:

- g + 2(3 + g) = - 4(g + 1) ← distribute parenthesis on both sides

- g + 6 + 2g = - 4g - 4 , that is

g + 6 = - 4g - 4 ( add 4g to both sides )

5g + 6 = - 4 ( subtract 6 from both sides )

5g = - 10 ( divide both sides by 5 )

g = - 2

As a check

Substitute g = - 2 into the equation and if both sides are equal then it is the solution.

left side = - 2 + 2(3 - 2) = 2 + 2(1) = 2 + 2 = 4

right side = - 4(- 2 + 1) = - 4(- 1) = 4

Since both sides are equal then g = - 2 is the solution
