Answer:
No.
Step-by-step explanation:
There are two different ways to do this - solve for x in the given equation or substitute the value for x and see if you get a true statement.
3x + 7 = 13 subtract 7 from both sides
3x = 6 divide by 3 on both sides
x = 2
3(3) + 7 = 13
9 + 7 = 13
16 ≠ 13
Therefore, x = 3 is not a solution for 3x + 7 = 13.
6. 12-3b<9
-3b<-3
b>1
7. (z/7)-6≥-5
(z/7)≥1
z≥7
Answer:
y = (3/2)x
Step-by-step explanation:
Parallel lines have the same slope only the constant in the slope intercept equation changes.
to find the new slope intercept, b, plug in the point (2, 3) and m = 3/2
3 = (3/2)(2) + b
3 = 3 + b
b = 0
The parallel line is
y = (3/2)x
Answer:
$1.20c + $3 ≥ $13.50 or $1.20c ≥ $10.50
Step-by-step explanation:
So Janie has $3, and earns $1.20 for each chore. The number of chores she does is c, and she needs $13.50 for the cd. The amount of money she has after doing c number of chores is $1.20c + $3. In order for her to have enough money to buy the cd, the amount of money she has after doing c chores must be greater than or equal to $13.50. This can be written as the inequality:
$1.20c + $3 ≥ $13.50
This will work, but we can simplify this inequality by subtracting $3 from both sides of the equation.
$1.20c ≥ $10.50
$1.20c + $3 ≥ $13.50 or $1.20c ≥ $10.50
I hope this helps. :)
Answer:
144.5
Step-by-step explanation:
Area of a triangle = one half of the base length times the height
The given base length is 17 cm and the given height is 17 cm
Hence, area =
17 * 17 = 289
289 / 2 = 144.5
Area = 144.5cm²
