Answer:
your answer is x >18
Step-by-step explanation:
Jahsiah's mistake was he added 9 to both sides of the equation. He should have subtracted 9 from both sides of the equation.
Here's the solution
-2x+9<-27
-9 -9
-2x/-2x<-36/-2x
when u divide by negative in inequalities, u change the sign. So ur correct answer is x>18
hope this helped.
Answer:
12; 8
Step-by-step explanation:
length-x
breadth-2/3x
2(x+2/3 x)=40
2×5/3x=40
10/3x=40
x=40÷10/3
x=40×3/10
x=12 (cm) length
2/3×12=8 (cm) breadth
Answer:
a
Step-by-step explanation:
the formula of the equation is y=mx+n; and if m=1/2 and n=-1 then it's y=1/2x-1
Answer: 4
There are three different ways to find the remainder. Since I don't know which lesson you are working on, I will show you all three methods.
<u>Long Division:</u>
<u>3x + 7 </u>
2x - 1 ) 6x² + 11x - 3
- <u>(6x² - 3x)</u> ↓
14x - 3
- (<u>14x - 7)</u>
4
<u>Synthetic Division:</u>
2x - 1 = 0 ⇒ x = 
| 6 11 -3
<u>| ↓ 3 7</u>
6 14 4
<u>Remainder Theorem:</u>
2x - 1 = 0 ⇒ x = 
f(x) = 6x² + 11x - 3
f(
) = 6(
)² + 11(
) - 3
= 6(
) +
- 3
