Here, angle (3x-1) is supplementary with 5x, so their sum would be equal to 180

3x - 1 + 5x = 180
8x = 180 + 1
x = 181/8
x = 22.625

Hope this helps!

Here's a graph of a linear function. Write the equation that describes that function.

Sedaia [141]

Answer:

The equation of the line is

2y=x+8

Step-by-step explanation:

This is a straight line graph.

And general equation of a straight is given by

y=mx+c

Where m is slope

c is the intercept on y axis at x=0

So at y=0, x=8. This is from the graph.

And inserting this value of y and x into the straight line equation

y=mx+c

0=-8m+c

Therefore, c=8m. Equation 1

Taking another point on the graph

at=0, y=4

Also, inserting this value of y and x into the straight line equation

4=0×x+c

4=0+c

Therefore, c=4.

Therefore the intercept is 4

From equation 1

c=8m c=4

Then m=c/8

m=4/8

m=1/2

Then the equations of then line is

y=mx+c

y=(1/2)x+4

Multiply through by 2

2y=x+8

The equation of the line is

2y=x+8

Jane cuts a foam block along the red line. When she looks at the newly

Answer:

B. A rectangle, 4 in by 3 in

Step-by-step explanation:

The foam has the shape of a cuboid with base of 10 in by 4 in and height of 3 in.

The foam has a front elevation of a rectangle with dimension of 4 in by 3 in. It has a left elevation of dimension 10 in by 3 in and a plan of dimension 10 in by 4 in.

If the foam is cut along the red line, the exposed face would be the same as the shape of the front elevation. Hence the shape of the cross section would be a rectangle with dimension of 4 in by 3 in.
