16y + 4 + -1(5y + 15)

Answers

Answer 1
Answer: 16y+4+-1(5y+15)16y+4-5y-1511y-11
Answer 2
Answer: Step One: Distribute the -1 to what's inside the parentheses. 
16y + 4 +(-1*5y) + (-1*15)
Step Two: Multiply
16y + 4 - 5y - 15
Step Three: Combine like terms
16y - 5y + 4 - 15
11y - 11
The answer is 11y - 11
Hope this helps!!

Which of the following Platonic solids is also a pyramid? A. tetrahedron B. Hexahedron C. octahedron D. Icosahedron E. dodecahedron F. None of These

Answers

Tetrahedron is a Platonic solids which is also a pyramid, i.e. Option (A).

What is pyramid?

Pyramid is a three dimensional shape. Pyramid is a polyhedron formed by connecting a polygonal base and a point. A triangular pyramid is also called a tetrahedron.

  • A tetrahedron is known as a triangular pyramid in geometry. The tetrahedron consists of 4 triangular faces, 6 straight edges, and 4 vertex corners. It is a platonic solid which has a three-dimensional shape with all faces as triangles.

So,

As mentioned in the above definition "A triangular pyramid is also called a tetrahedron."

Hence, we can say that Tetrahedron is a Platonic solids which is also a pyramid, i.e. Option (A).

2x-y=4 find the slope of the graph

Answers

The\ slope-intercept\ form:y=mx+b\n\nm-slope\nb-y-intercept\n\n2x-y=4\ \ \ \ /-2x\n\n-y=-2x+4\ \ \ \ \ /\cdot(-1)\n\ny=2x-4\n\nSlope:m=2
Change it to the form of y=mx+b where m = slope and b is the intercept. So to do this just move the x over, then you divide each side by -1, because the y is negative. So you finally get y=2x-4, the slope is 2!

Shown are lines p , r , t , and w. Suppose angles 8 and 10 are congruent. Given this fact, which two line must be congruent? Show all work to receive credit.

Answers

Answer:

  lines t and w must be parallel

Step-by-step explanation:

Angles 8 and 10 are alternate interior angles with respect to transversal r across lines t and w. If those angles are congruent, then lines t and w must be parallel.
