1.) -50 = -2(a + 3)

-50 = -2a - 6

-50 + 6 = -2a

-44 = - 2a

a = 22

2.) 4 (x - 2) = 2(x - 4) + 2x

4x - 8 = 2x - 8 + 2x

4x - 8 = 4x - 8

0 = 0

All real numbers

3.) 5(y - 2) - 2. = 2(y + 1) - 5

5y - 10 - 2 = 2y + 2 - 5

5y - 12 = 2y - 3

3y = 9

y = 3

4.) -4(p + 1) = 2(8 - 2p)

-4p - 4 = 16 - 4p

- 4 ≠ 16

No solution

Raphael paid $ 160$160 for a camera during a 75 %75% off sale. What was the camera's regular price?

Kay [80]

So paid160

75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost

Given the equation f(x) = (x + 3)2 – 8, fill in the blanks: Axis of symmetry: x = _______a0 Vertex: ( _______a1, _______a2) Numb

frutty [35]

We have been given an equation $f(x)=(x+3)^2-8$ . We are asked to fill in the blanks using our given equation.

The axis of symmetry will be the vertical line passing through vertex.

First of all, we will convert our given equation in standard vertex form of parabola as:

Standard vertex form of parabola: $y=(x-h)^2+k$ , where (h,k) is vertex of parabola.

$f(x)=(x-(-3))^2-8$

Upon comparing our function with standard vertex form, we can see that vertex of parabola is at $(-3,-8)$ .

The axis of symmetry will be vertical line passing through point $(-3,-8)$ . The vertical line will pass through $x=-3$ , therefore, the axis of symmetry is $x=-3$ .

Since our given parabola is an upward opening parabola, so it has a minimum at $(-3,-8)$ . This means that parabola will intersect the x-axis at two points. Therefore, there are two real solutions for the given function.
