b. 84%

2. 175

3. $867.18

Step-by-step explanation:

1. a.2.32-0.36=1.96

1.96/0.36=5.44

5.44*100=544

b. 1.96/2.32=0.84

0.84*100=84

2. let x = # of 7th graders

let y = # of 8th graders

y is 125% of x

y=1.25x

x=140

y=1.25*140

y=175

3. A=P(1+r)^t

A=700(1+0.055)^4

A=867.18

Solve and graph the solution.<br> |4x-13| = 5x+4
konstantin123 [22]

Answer: x = -17

Step-by-step explanation:

4x-13=5x+4

(4x-13)+(13-5x)=(5x+4)+(13-5x)

4x-13+13-5x=5x+4+13-5x

4x-5x-13+13=5x-5x+4+13

-x=17

x=-17

The line of symmetry for the quadratic equation y = ax2 - 2x - 3 is x = 1. What is the value of "a"?
timama [110]
Y = a(x - h)² + k • (h, k) is the vertex • x = h is line of symmetry so y = ax² - 2x - 3 y/a = x² - 2/ax - 3/a y/a + 3/a = x² - 2/ax y/a + 4/a= x² - 2/ax + (-1/a)² ← completing the square y/a + 4/a= (x - 1/a)² y/a = (x - 1/a)² - 4/a y = a(x - 1/a)² - 4 so since you've been given h = 1 then 1/a = 1 and so a = 1
