Answer:
f(-2) = 5
Step-by-step explanation:
To find f(-2), plug in -2 wherever there is an x.
f(x) = 4x² + 3x - 5
f(-2) = 4(-2)² + 3(-2) - 5
f(-2) = 4(4) + 3(-2) - 5
f(-2) = 16 - 6 - 5
f(-2) = 10 - 5
f(-2) = 5
Answer:
x = 10/27
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
9/5x = 2/3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 9/5: x = 10/27
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 9/5(10/27) = 2/3
- Multiply: 90/135 = 2/3
- Simplify: 2/3 = 2/3
And we have our final answer!

C. 10in 24in 26in
Step-by-step explanation:
Right Scalene Triangle
Side a = 24
Side b = 10
Side c = 26
Angle ∠A = 67.38° = 67°22'48" = 1.17601 rad
Angle ∠B = 22.62° = 22°37'12" = 0.39479 rad
Angle ∠C = 90° = 1.5708 rad = π/2
Area = 120
Perimeter p = 60
Semiperimeter s = 30
Height ha = 10
Height hb = 24
Height hc = 9.23077
Median ma = 15.6205
Median mb = 24.5153
Median mc = 13
