Final Answer:
x=5/8
Answer:
<u>X=7,-3</u>
Step-by-step explanation:
x^(2)-4x-21=0
(x-7)(x+3)=0
x=7,x=-3
Answer:
the desired equation is y = 5x + 6.
Step-by-step explanation:
Any line parallel to y = 5x - 7 has the same slope (5).
Using the slope-intercept formula,
y = mx + b ↔ 11 = 5(1) + b, or b = 6.
Then the desired equation is y = 5x + 6.
Answer:
option 4
Step-by-step explanation:
Solving the inequality
4.5 + 1.2x ≥ 10 - x ( add x to both sides )
4.5 + 2.2x ≥ 10 ( subtract 4.5 from both sides )
2.2x ≥ 5.5 ( divide both sides by 2.2 )
x ≥ 2.5
3, 4, 5, 6 are all greater than 2.5, thus
All values in the set make the inequality true
Answer:
$150
Step-by-step explanation:
So, 60 dollars is 40% of the original price. So 30 dollars is 20% of the original price, and 150 dollars is 100% of the original price. So, the original value of the rice cooker is 150 dollars.
