Answer:
B
Step-by-step explanation:
To solve for the slope:
(2-(-3))/(4-2)=5/2
y=5/2x+b
plugin points:
2=5/2(4)+b
2=10+b
b=-8
so equation of the line is y=5/2x-8
and in standrd form its 5x-2y=16
She should use 50% off.
964 divided by 1/2 = $482
964 - 400 = $564
Answer:
The answer is either 18pi or 56.55
Step-by-step explanation:
Answer:
76
Step-by-step explanation:
given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0
then the discriminant is Δ = b² - 4ac
given 3x² - 10x = - 2 ( add 2 to both sides )
3x² - 10x + 2 = 0 ← in standard form
with a = 3, b = - 10 and c = 2
b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
Answer:
x>19.5
Step-by-step explanation:
Let's solve your inequality step-by-step.
x−4>15.5
Step 1: Add 4 to both sides.
x−4+4>15.5+4
x>19.5
Answer:
x>19.5
