Answer:
$11.25
Step-by-step explanation:
1.25 × 9 = 11.25
Answer:
DE ≈ 16.1, ∠E ≈ 60.3°, ∠D ≈ 29.7°
Step-by-step explanation:
use pythagorean theorem:
DE² = 8² + 14² => DE = √8² + 14² ≈ 16.1
use inverse tangent function:
∠E = 
(14/8) ≈ 60.3°
∠D = (8/14) ≈ 29.7°
Answer is x is squared
A
that would make a parabola
A is the answer
Answer:
1. x=27
2. x=3
Step-by-step explanation:
<h3>the first one </h3>
let's solve your equation step-by-step.
x−7=20
Step 1: Add 7 to both sides.
x−7+7=20+7
<h3>the second one </h3>
Let's solve your equation step-by-step.
3x+6=12x−21
Step 1: Subtract 12x from both sides.
3x+6−12x=12x−21−12x
−9x+6=−21
Step 2: Subtract 6 from both sides.
−9x+6−6=−21−6
−9x=−27
Step 3: Divide both sides by -9.
−9x/−9=−27/−9
<h3 />
2x - y = 6
2x - (6x - 12) = 6
2x - 6x + 12 = 6
-4x = -6
x = 3/2
y = 6(3/2) - 12
y = 9 - 12
y = -3
(3/2,-3)
