nikitadnepr [17]

Answer:

Step-by-step explanation:

From the graphs attached,

Let the coordinates of the two points given on the black line in the first graph are (-4, 2) and (-1, 10).

When these points have been rotated by 90° about the origin,

Rule for the rotation will be,

(x, y) → (y, -x)

Therefore, coordinates of the image points will be,

(-4, 2) → (2, 4)

(-1, 10) → (10, 1)

Therefore, red line given given in graph (1) and black line (After rotaion of 90° clockwise) in graph (2) will be same.

SVEN [57.7K]

Answer:

John needs 3\frac{3}{4}  yards of blue ribbon.

Step-by-step explanation:

We have been given that Jon uses a piece of red ribbon witch is 3/4th yard long. Jon also needs blue ribbon that is 5 times as long as the ribbon. We are asked to find the amount of blue ribbon that John needs.

To find the amount of blue ribbon that John needs, we will multiply amount of red ribbon by 5 as shown below:

\text{Amount of blue ribbon}=5\times \frac{3}{4}

\text{Amount of blue ribbon}=\frac{5\times 3}{4}

\text{Amount of blue ribbon}=\frac{15}{4}

\text{Amount of blue ribbon}=3\frac{3}{4}

Therefore, John needs 3\frac{3}{4}  yards of blue ribbon.

What is the equation of a line in slope intercept form that passes through (-2,2) and is perpendicular to the graph of y=1/2x-3.
tangare [24]
The answer is y = -2x-2

To find the slope of a line perpendicular to your equation, you just need to find the reciprocal. This just means flip the signs (change positive to negative, or negative to positive) and flip the numerator and denominator. So if you have 1/4 as your slope, the perpendicular slope would be -4/1 (which is just negative 4).

I changed the “b” from -3 to -2 so it would run through the points (-2, 2).

I hope this helps :)

Choose the equation that represents the graph.
Pepsi [2]

Answer:

y=-2x-4

Step-by-step explanation:

1) In this equation, -4 is the y-intercept (which is the point in the graph when x is 0 and y is something.)

2) Then, you have to check if the graph also has a y-intercept of -4 (it does)

3) Find out what the slope of the graph is. In this case, it is -2

4) If the equation also has a slope of -2 and y-intercept of -4, then it represents the graph.

Hope this helps :)
