Answer:

Step-by-step explanation:

Use the fact that C + 118 = 180 Subtract 118 from both sides

C + 118 - 118 = 180 - 118

C = 62

C + 57 = B C and A are remote interior angles. They equal the exterior angles that are not supplementary to B.

62 + 57 = B

B = 119

Which function has a vertex at the origin?

dlinn [17]

Answer:

(d) f(x) = -x²

Step-by-step explanation:

For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...

f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)

f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)

Of the offered answer choices, the only one with a vertex at the origin is ...

f(x) = -x² . . . . . a=-1

System of equations by substitution how do this? y= x+2 y= -4x+7

jekas [21]

Equations are given,
y= x+2

y= -4x+7

As you can see both the expressions, x+2 and -4x+7 are equal to "y". That means they are equal to each other too.

So let's equal them and solve it.

 $x+2=-4x+7\\ \\ x+2+4x=7\\ \\ x+4x+2=7\\ \\ 5x+2=7\\ \\ 5x=7-2\\ \\ 5x=5\\ \\ x=\frac { 5 }{ 5 } \\ \\ x=1$

Now we have x's value we will plug it in the first equation to find "y".

 $x=1\\ \\ y=x+2\\ \\ y=1+2\\ \\ y=3$
