Answer:
you answer would be A,B,D there all the answer u cant just have one also I just took the test im from k12
y = 3x-2x∧2+5x∧3
When we replace x with value 3 we get
y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126
good luck!!!
Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Using ΔAHC , then
∠ACH = 180 - (2x + 100) = 180 - 2x - 100 = 80 - 2x
∠ECD = ∠ACB ( vertical angles are congruent ), thus
∠ECD = ∠ACH + ∠HCB, that is
3x = 80 - 2x + x
3x = 80 - x ( add x to both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Answer:
x > 3
Step-by-step explanation:
16x + 8 > 12x + 20 <== subtract 12x from both sides
- 12x - 12x
4x + 8 > 20 <== subtract 8 from both sides
- 8 - 8
4x > 12 <== divide both sides by 4
/4 /4
x > 3
This means that x is any value that is greater (bigger) than 3.
Hope this helps!
