Answer:
7.6
Step-by-step explanation:
From the graph, we know the lengths of two legs.
a = 3
b = 7
Knowing this, we can use the Pythagorean Theorem to solve for c, the hypotenuse. (remember, a^2 + b^2 = c^2)
c = √a2 + √b2
= √(7)2 + √(3)2
= √49 + √9
= √58
= 7.6
Answer:
20 I'm pretty sure it's right but if not sorry
Step-by-step explanation:
80x.2=16
16÷.8= 20
Answer:
- -6x² - 6 = -7x - 9
- -6x² + 7x - 6 + 9 = 0
- -6x² + 7x + 3 = 0
- 6x² - 7x - 3 = 0
<u>Discriminant:</u>
- D = (-7)² - 4*6*(-3) = 49 + 72 = 121
<u>Since D > 0, there are 2 real solutions:</u>
- x = (- (-7) ±√121 )/12
- x = (7 ± 11)/12
- x = 1.5, x = -1/3
Answer:
An exponential
Step-by-step explanation:
The second one is ratio
Answer:
y = 5/4x + 12
Step-by-step explanation:
5x - 4y = 4
-4y = -5x + 4
y = (-5x + 4)/-4
y = 5/4x - 1
Parallel Slope ---> m = 5/4
(-8, 2)
y = mx + b
2 = 5/4(-8) + b
2 = 5 * -2 + b
2 = -10 + b
12 = b
b = 12
y = 5/4x + 12 <---- This is the answer
Hope this helps!
