Answer:
29/25
Step-by-step explanation:
<u>Answer:</u>
<h2>1. a</h2><h2>2. b</h2><h2>3. b</h2><h2>4. b</h2><h2>5. 22</h2>
<u>Explanation:</u>
1.
n²-49=0
n=√49
n=7
2.
x²+64=0
x=√64
x=8
3.
if A=144x²
l = √A
l = √(144x²)
l = 12x
4.
b = (24×2)/3b
b = 48/3b
b = 16/b
b² = 16
b = √16
b = 4 in <em>(-4 is correct in algebra but there's no negative lengths in geometric shapes)</em>
5.
x²+z = 103
x² = 103-z
x = √(103-z)
for x = -9 and 9 (103-z) must equal 81
z = 103 - 81 = 22
x = √(103-22)
x = √81
x = -9 , 9
Answer:
y = 1/4x - 6
Step-by-step explanation:
Slope intercept form is y = mx+b
The y-intercept is b
The slope is mx
So just plug in
y = 1/4x - 6
The reason is it minus is because -6 is negative so it'll rule out the plus either way.

you could probably simplify that down though</span>
