what is the coordinate points for r(-2)=0​

Answer:

F(1) = - 1

Step-by-step explanation:

F(x) = 2x-3

F(1) = 2(1)-3 (plug in 1 for x because 1=x)

F(1) = 2-3 (multiply 1 and 2)

F(1) = - 1

Answer:

[tex](f + g)(x) = (3x + 9) + (5 {x}^{2} ) \\ = 5 {x}^{2} + 3x + 9[/tex]

I hope I helped you^_^

Answer:

5x² + 3x + 9

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= 3x + 9 + 5x²

= 5x² + 3x + 9 ← in standard form

Answer:

1. 11

2. 20

3. 34

4. 12.6

5. 18

6. 105

Step-by-step explanation:

We are told that ---> t = 0, x = 1.5, y = 6, and z = 23

1. y + 5

= 6 + 5

= 11

2. z - 2x

= 23 - 2(1.5)

= 23 - 3

= 20

3. 2z - 2y

= 2(23) - 2(6)

= 46 - 12

= 34

4. 2.6y - 2x

= 2.6(6) - 2(1.5)

= 15.6 - 3

= 12.6

5. 4(y - x)

= 4(6 -  1.5)

= 24 - 6

= 18

6. 4(2 + z) + 5

= 4(2 + 23) + 5

= 8 + 92 + 5

= 105

Answer:

20

Step-by-step explanation:

-7-5=-12

-4-12=-16

AB^2=(-12)^2+(-16)^2

AB^2=144+256

Ab=

no it can't

if u look closely at other numbers like 5 4 and 3,they can be multiplied 2 to give 10 ,6 and 8

but 10×2 isn't 12

it's 20

so it's not possible

Answer:

1 3/4 lbs of skittles

Step-by-step explanation:

Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs

Complex way:

(I'm assuming "1/1/4" means "1 1/4")

This is simply ~Subtraction~

The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).

So we need to know what added to 1 1/4 equals 3.

Equation: t= 1 1/4 + s

Equation: t= 1 1/4 + s

We can replace (t) with 3 because we know this variable.

1. 3= 1 1/4 + s

To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation

2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s

The right side cancels out = 0 and the left = 1 3/4

3. 1 3/4= s

Flip it around for the traditional view

4. s = 1 3/4

In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)

Answer:

6/5

Step-by-step explanation:

We can use the slope formula to find the slope

Slope formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], where the x and y values are derived from know points

The points chosen can vary as there are many given but the ones I chose were (6,9) and (11,15)

Now that we chose two points we want to define the variable ( the variables are x2, x1, y2 and y1 )

Define Variables

x1 = x value of first point which would be 6

x2 = x value of second point which would be 11

y1 = y value of first point which would be 9

y2 = y value of second point which would be 15

Now that we have defined our variables the next step is to plug in the variables into the slope formula

slope formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

y2 = 15, y1 = 9, x2 = 11 and x1 = 6

* plug in values *

[tex]m=\frac{15-9}{11-6}[/tex]

subtract top numbers

[tex]m=\frac{6}{11-6}[/tex]

subtract bottom numbers

[tex]m = \frac{6}{5}[/tex]

there is no simplification needed meaning that the slope in simplest form is 6/5

Answer: While I don’t have the picture to actually know the answer I will explain how to get it.

Step-by-step explanation:

1. If the shapes are on a grid count the amount of grid squares that are located between each end point of the shape. If it’s not on a grid use a ruler to measure the side lengths. You will need to find out the side amounts for both shapes L and S.

2. From there if the L shape is SMALLER than the S shape, then take the S shape’s sides and divide it by the L shape’s sides, and whatever number you get from each of your division problems will be your scale factor. BUT If the L shape is BIGGER than the S shape then easiest way to find out your scale factor is to take the last scale factor you got and convert it into a fraction. For example, if you got 3 then it would be 1/3. Hope this helped!

The answer is 2.

Answer:

a) To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

b) To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:

(5, 7.8)

Step-by-step explanation:

There are several ways to solve this problem, but all of them involve similar triangles and ratios.

See the attached image.

The horizontal distance between points D and E is 11 - 1 = 10.  If a segment 10 units long is divided in the ratio 2:3 (as shown by the two smaller segments of length  a  and  b), then

[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{10}=\frac{2}{5}[/tex]

"Cross-multiply" to get

5a = 20

a = 4

To get the x-coordinate of point G, add 4 to 1, the x-coordinate of D.

The x-coordinate of G is 1 + 4 = 5.

The same idea can be used on the second coordinate of G.

The vertical distance from D to E is 15 - 3 = 12.

[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{12}=\frac{2}{5}[/tex]

5a = 24

a = 24/5 = 4.8

The y=coordinate of G is 3 + 4.8 = 7.8

Answer:

x=145

Step-by-step explanation:

x+10+x=720-460

Answer:

125°

Step-by-step explanation:

Accumulate every detail given:

720 = 120+100+120+120+ (x+10) + x

720 = 120+100+120+120+2x+10

720=470+2x

Flip the equation to avoid negative equation

470+2x=720

2x=720

x=250/2

x=125

125 Is the final answer
