So, we need to figure out how much times the body size of the flea it can jump. First, we need to figure out the size of the flea: 2^-4=0.0625

Now that we have the size of the flea, we need to figure out how high it can jump: 2^3=8

After we figure out the size of the flea, we need to divide 8 by .0625 because it is inverse operations to multiplication: 8/.0625=128

Answer: The flea can jump 128 times higher than it's body size.

What is the solution to the system of equations? -2x + y = -5 3x – 2y = 12 A) (3, 1) B) (6, 3) C) (-2, -9) D) (-2, -1)

Answer:

The correct answer is D) (-2, -1)

Step-by-step explanation:

In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.

-4x + 2y = -10

3x - 2y = 12

---------------------

-x = 2

x = -2

Now that we have the value for x, we can find y by plugging the x value into either equation.

-2x + y = -5

-2(2) + y = -5

-4 + y = -5

y = -1

The sum of two numbers is 109. If four times the smaller number is subtracted from the larger number, the result is 4. What are

anygoal [31]

Let the numbers be x&y

X+y=109

Taking a as the smallest number we multiply by 4

So according to the question you will have this equation

Y(as the largest number) -4x=4. Y-4x=4

Then find y

Y=4x+4

Substitute y on the first equation to get a

X+y=109

X+4x+4=109

X=21

21+y=109

Y=88

Enter the slope-intercept equation for the image of line ℓ after a clockwise rotation of 90°. (Hint: To find the image of line ℓ

Free_Kalibri [48]

Answer:

y = -2x - 2

Step-by-step explanation:

From the graph attached,

If the line 'l' passes through two points A(0, -1) and B(4, 1).

Rule for the rotation of any point (x, y), 90° clockwise about the origin is,

(x, y) → (y, -x)

By this rule,

A(0, -1) → A'(-1, 0)

B(4, 1) → B'(1, -4)

Let the equation of the line A'B' is,

y - y' = m(x - x')

where m = slope of the line A'B'

And (x', y') is a point lying on the line.

Slope of the line passing through A' and B' will be,

m = $\frac{y_2-y_1}{x_2-x_1}$

m = $\frac{0+4}{-1-1}$

m = -2

Therefore, equation of the line passing through (-1, 0) and slope = -2,

y - 0 = (-2)(x + 1)

y = -2x - 2

So the equation of the line after rotation of lie 'l' by 90° clockwise will be,

y = -2x - 2
