Answer:

The answer to your question is (-1, 4) The lines cross in one point so they have only one solution.

Step-by-step explanation:

Data

Equation 1     x - 4y = -17

Equation 2    y = 4x + 8

Solve for y

Equation 1          y = -x/-4 - 17/-4

                          y = x/4 + 17/4

Equation 2         y = 4x + 8

See the graph below

These lines cross in point (-1, 4), so that is the only one solution.

If the lines were the same line they would have infinite solutions

What is the value of s?<br><br><br><br> 0.7(3s+4)−1.1s=7.9
Natali [406]
Before isolating s we need to simplify the equation using order of operations.
.7(3s+4)-1.1s = 7.9 -------> First distribute the .7
2.1s + 2.8 - 1.1s = 7.9 ------> Now combine like terms
s + 2.8 = 7.9 ------> Now to isolate s by subtracting 2.8 from both sides!

s = 7.9 - 2.8
s = 5.1

To find the lateral area you have to ?
Vlad [161]

To find the lateral surface area of a pyramid, you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.
