Answer:

they answer would be y = 3x + 2

Step-by-step explanation:

Convert the equation to slope intercept form to get y = –1/3x + 2.  The old slope is –1/3 and the new slope is 3.  Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

The Sunday school teacher gave 5 Friend's Day invations to each of her 19 students to give to their friends. She had 5 left over
lesya [120]
I'm pretty sure its 100 because if she gave each of her 19 students 5 invitations that equals 95. (19×5=95) And She had 5 leftover equals 100. (95+5=100)

The rectangular prism is made of 8 cubes and has and edge length of 1/2 in, what is the volume
sashaice [31]
Hello!

To find the volume of the prism you first have to find the volume of a cube

To do this you use the equation

V =  a^{3}

V is volume
a is side length

Put in the values you know

V =  \frac{1}{2}^{3}

Solve

V = 0.125

Now to find the volume of the prism you multiply the volume of one cube by the amount of cubes in the prism

0.125 * 8 = 1

The answer is 1 cubic inch

Hope this helps!
