Answer: 7(b-1)^2-63
Step-by-step explanation:
Factor out 7
7(b^2-2b-8)
Add and subtract (-1)^2:
7(b^2-2b-8+(-1)^2-(-1\)^2)
Complete the square:
7((b-1)^2-8-(-1)^2)
Simplify:
7(b-1)^2-63
Crystal earns $5.25 per hour mowing lawns.
a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 2 hours and 15 minutes?
A. m(h) = 5.25h; $11.29
B. m(h) = 2h +15; $25.50
C. m(h) = 5.25h; $11.81
D. m(h) = [tex]\frac{h}{5.25}[/tex]; $0.43
Answer: C. m(h) = 5.25h; $11.81
The equation is:
m = 5.25*h
If she works 2 hours and 15 minutes she will earn:
first we need to convert hours and minutes in decimal hours.
2 hours and 15 minutes = 2,25 hours
m = 5,25* 2,25 = $11.8125
Step-by-step explanation:
Answer:
m(h)= 5.25h; 11.81
11.81 is the answer

Does anyone know how to do this?
Answer:
Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3
Help me please !!!!! I need help

The circumference of a circle is m. What is the area , in square meters ? Express your answer in terms of pi
Answer:
area = m²/2π
Step-by-step explanation:
∵ circumference of circle = 2πr = m
∴ r = m/2π
∵ area of circle = πr²
∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

What is the coefficient in the expression 4x + 2
O2
O4
Ox
O+
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

3. Hessa is building a scale model of a park. She uses a scale of 12 cm to represent 1.5 m. a) The actual length of the bridge is 20 m. What is the length of the model bridge? b) In the model, the height of the climbing frame is 10 cm. What is the actual height of the frame?
Answer:
160cm
80cm
Step-by-step explanation:
If 12cm = 1.5m
convert cm to meter
1 meter = 12/1.5 = 8cm
20m = 20m x 8 cm = 160 cm
10cm = 10 x 8 = 80cm

Mimi has 9/10 of a punnet of strawberries. Jamie has
four times as many strawberries as Mimi. How many
punnets of strawberries does Jamie have?
Give your answer as an improper fraction in its
simplest form.
Answer:
36/10 (improper fraction)
3 3/5 of a punnet of strawberries(mixed Number)
Step-by-step explanation:
Mimi = 9/10 of a punnet of strawberries
Jamie has four times as many strawberries as Mimi
Jamie = 9/10 × 4
= (9×4) / 10
= 36/10
= 3 6/10
= 3 3/5 of a punnet of strawberries
Jamie = 3 2/5 of a punnet of strawberries
