what is the distance between point P (-5,7) and point Q (6,7) ?

Answer: $4

Step-by-step explanation: we know he spent 28 dollars in total and 16 of those was on a pair of pants so we can subtract 16 from 28 to get 12

we also know he bought 3 shirts in total and because 12/3=4 each shirt must have cost 4 dollars.

We can check the answer by combining the price of the shirts (12)

with the price of the pants (16) because 12+16=28 we know the cost of each shirt has to be $4.

Answer:

Each shirt was 4 dollars.

Step-by-step explanation:

28 - 16 = 12. 12 divided by 3 = 4.

The equation that models the balance y after x​ months is: y = -130x + 1200.

Month    Balance

0             1200

6            420

8             160

Hence,

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

First coordinate:

m = (420 - 1200)/(6 - 0)

m = -780 /6

m = -130

Second coordinate;

m = (160 - 420)/(8 - 6)

m = -260/2

m = -130

The formula for equation in slope intercept is

y = mx + c

where;

m = slope

c = y-intercept

So, equation is;

y = -130x + 1200

Therefore the equation is y = -130x + 1200.

[tex]p+p+2=20[/tex]

Step-by-step explanation:

This is what my math teacher told us, so I don't know try this.

Step-by-step explanation:

p + j = 20

j = 2p + 2 --> -2p + j = 2

[tex] \binom{1 \: 1}{ - 2 \: 1} \: \binom{20}{2} = \binom{p}{j} [/tex]

Step-by-step explanation:

that simply means we use one equation to express one variable by the other, and then we use that identity in the second equation (substituting one variable by the expression of the other variable. and then we solve for that remaining variable.

finally we use one of the original equations to solve for the second variable.

4x + y = 19

so, that gives us

y = 19 - 4x

we use that now in the second equation :

6x + 7(19 - 4x) = 1

6x + 133 - 28x = 1

-22x + 133 = 1

-22x = -132

22x = 132

x = 6

now, let's use e.g.

4x + y = 19

4×6 + y = 19

24 + y = 19

y = -5

The greater factor of 432, if 12 is the greatest common factor between the two factors is 36

The Greatest Common Factor is defined as the largest number that is a factor of two or more numbers. For example, the GCF of 24 and 36 is 12, because the largest factor that is shared by 24 and 36 is 12. 24 and 36 have other factors in common, but 12 is the largest.

The factors of 432 are 36,12, 24 ,18,4,108

But the two factors of 432 that has a multiple of 12 is 12 and 36

12× 36 = 432

The factors of 12 = 1,2,3,4,6,12

The factors of 36 = 1,2,3,4,6,9,12,18,36

the common factors are ; 1,2,3,4,6 and 12

The length and width of a rectangle that maximises the enclosed area are 162.5 yards. The maximum area is 26,406.25 square yards.

In the given question we have to find the maximum area of the rectangular area.

A farmer with 650 meters of fencing wants to enclose a rectangle plot that border on a river.

As we know that the perimeter of rectangle

P= 2(l+b)

Let length of the rectangle is x yards and width is y yards.

So the equation should be

2(x+y) = 650

Divide by 2 on both side we get

x+y = 325................(1)

From the area of rectangle is

A = xy

From the equation the value of y is 325-x.

Now putting the value of y

A = x(325-x)

A = 325x-x^2

On differentiating

dA/dx = 325-2x

Putting dA/dx=0

325-2x=0

Subtract 325 on both side we get

-2x= -325

Divide by -2 on both side we get

x = 162.5 yards

Now putting the value of x in the y=325-x

y=325-162.5

y=162.5 yards

So the maximum area is

A= 162.5*162.5

A= 26,406.25 square yards

Hence, the length and width of a rectangle that maximises the enclosed area are 162.5 yards. 26,406.25 square yards is the maximum area.

The quadratic equation 8x² + 16x + 3 = 0 can be solved by using the quadratic formula.

The given quadratic equation is : 8x² + 16x + 3 = 0

Comparing this equation with  ax² + bx + c = 0 we get :

a = 8 , b = 16 and c = 3

Now we will use the quadratic formula:

[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}}[/tex]

Now we will substitute the values in this formula to find the values of x that satisfy the quadratic equation.

[tex]{\displaystyle x={\frac {-16\pm {\sqrt {16^{2}-4\times8\times3}}}{2\times8}}}\\\\{\displaystyle x={\frac {-16\pm {\sqrt {160}}}{16}}}\\\\[/tex]

The values for x that satisfy the equation are the roots or zeros of both expressions on the left-hand side of the equation. In a quadratic problem, there can only be two possible solutions.

A problem is said to have a double root if there is only one solution. One real double root, two complex solutions that appear to be complex conjugates of one another, two real solutions, or two real solutions if all the coefficients have real values are the only options.

What is sample space?

In probability theory, the set of all feasible outcomes or outcomes of an experiment or random trial is referred to as the sample space. The sample points, or potential ordered outcomes, are listed as elements in the set used to represent the sample space.

Let,

S = {5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}

F = {8, 9, 10, 11, 12, 13}

G = {12, 13, 14, 15}

n(S) = number of elements in set S are 12.

n(F) = 6

n(G) = 4

n(F and G) = common elements in F and G = 2

n(F or G) = n(F) + n(G) - (F and G)

n(F or G) = 6 + 4 - 2

n(F or G) = 8

Now, using the general addition rule,

P(F or G) = P(F) + P(G) - P(F and G)

Here,

P(F) = n(F)/n(S) = 6/12 = 1/2

P(G) = n(G)/n(S) = 4/12 = 1/3

P(F and G) = n(F and G)/n(S) = 2/12 = 1/6

⇒ P(F or G) = 1/2 + 1/3 - 1/6

                   = 5/6 - 1/6

                   = 4/6

⇒ P(F or G) = 0.667

The street was 900m long when the speed is 15m/s and, the time is 60 seconds.

To calculate speed, divide the distance traveled by the time it took to complete the voyage, so speed = distance divided by time. To determine the distance, multiply the speed by the passage of time. These equations can be reduced as s=d/t, where s represents speed, d represents distance, and t represents time.

Distance divided by time equals speed. Distance = time * speed

To solve for speed or rate, utilize the speed formula, s = d/t, which implies speed equals distance divided by time. To solve for time, utilize the time formula, t = d/s, which implies time equals distance divided by speed.

Given,

Speed of the biker who travels down the street=15m/s

For figure 4,

The sides of the given triangle are 2.5 cm, 3 cm, and 3.5 cm.

The height of the triangle is given as 2 cm.

Then, the perimeter of a triangle = 2.5 + 3 + 3.5

now solve the intercepts:

to find x intercept, substitute in 0 for y and solve for x.

⇒ 2x+3y=6

⇒ 2x+3(0)=6

⇒ 2x+0=6

⇒ 2x=6

⇒ x=6/2

⇒ x=3

hence we get (3,0)

now, to find y intercept, substitute in 0 for x and solve for y.

⇒ 2x+3y=6

⇒ 2(0)+3y=6

⇒ 0+3y=6

⇒ 3y=6
