Answer:b
Step-by-step explanation:
Step 1 :
x
Simplify —
4
Equation at the end of step 1 :
x
— - -8 ≥ 0
4
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 4 as the denominator :
-8 -8 • 4
-8 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (-8 • 4) x + 32
———————————— = ——————
4 4
Equation at the end of step 2 :
x + 32
—————— ≥ 0
4
Step 3 :
3.1 Multiply both sides by 4
Solve Basic Inequality :
3.2 Subtract 32 from both sides
x ≥ -32
Inequality Plot :
3.3 Inequality plot for
0.250 x + 8.000 ≥ 0
One solution was found :
x ≥ -32
2.5h - 15 = 4h. -15 = 1.5h. -10 = h. Your answer is h = -10
Answer:
Maggie is 13 years old.
Step-by-step explanation:
1M + 1B = 62
rearrange to get:
1B = 62 - 1M
4M - 3 = 1B
substitute B with 62 - 1M so there is only one variable. this gives:
4M - 3 = 62 - 1M
Get all the variables on one side:
4M + 1M - 3 = 62
Get all non variables on the other side:
4M + 1M = 62 + 3
simplify:
5M = 65
Divide both sides by 5 to get the M by itself:
M = 13.
BONUS:
M + B = 62
B = 49
So her brother is 49 years old.

Answer: What is the question?
Step-by-step explanation:
Slope intercept form: y = mx + b
mx = slope
b = y-intercept
We know the y intercept is 0, so nothing will be written there.
To find the slope of this line, we can use the slope formula.
We'll use the points (1, 0) and (3, 1) to find the slope.
Now we can just plug these values into the equation to find the slope.
1 - 0 / 3 - 1
1 / 2
The slope of the line is 1/2, or 0.5.
The slope-intercept form of this line can be written as:
y = 0.5x
