Answer:
m = 2/3
Step-by-step explanation:
4y = -6x + 72
y = -3/2x + 18
Negative reciprocal = 2/3
decide if these are equivalent ratios by simplifying. 12/27 and 20/36
Answer:
they are not equivalent
Step-by-step explanation:
12/27 reduces to 4/9 if you divide by 3
20/36 reduces to 5/9 if you divide by 4
4/9 ≠ 5/9
Step-by-step explanation:
Get your answer by reducing them:
12/27=4/9 ( in the table of 3)
20/36=5/9 ( in the table of 4)

Michelle is measuring fabric to make pillows. She needs 30 feet
of fabric, but she only has 6 2/3 yards of fabric. How many more
feet of fabric does she need?
she needs 10 feet because 6 2/3 yard converted into feet is 20 and 30-20=10

Find the interest on $4,000 at 3% for 4 months.
Answer:
$80 interest will be owed for 4 months
Step-by-step explanation:
P is the principal amount, $4000.00.
r is the interest rate, 8% per year, or in decimal form, 8/100=0.08.
t is the time involved, 3....month(s) time periods.
Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.
Do this by dividing your time, 3- month(s), by 12, since there's 12 months in 1 year.
So, t is 0.25....year time periods.
To find the simple interest, we multiply 4000 × 0.08 × 0.25 to get that
Find the area of this shape. (Note: the figure is NOT drawn to scale)
Answer:
The area of this shape is [tex]50cm^2[/tex].
Step-by-step explanation:
To find the area of this figure, you only need to know the area of the rectangle and the area of the triangle. The area of the rectangle would be 5 * 6 = [tex]30cm^2[/tex]. Since the length of the rectangle plus the base of the triangle is equivalent to 14, that means the base of the triangle is equal to 14 - 6 = 8 cm. The formula for the area of a triangle is [tex]\frac{1}{2} bh[/tex], the base you now know is 8 cm, and the height is 5 cm, which means the area of the triangle would be [tex]\frac{1}{2} *5*8[/tex] = [tex]\frac{1}{2} * 40[/tex] = [tex]20cm^2[/tex]. Add the area of the rectangle to the area of the triangle and you'll get the area of the entire shape, which is 30 + 20 = [tex]50cm^2[/tex].

Answer:
Volume = 120 cubic cm
Step-by-step explanation:
We would apply the formula for determining the volume of a square bases pyramid which is expressed as
Volume = 1/3 x base area x height
From the diagram,
length of square base = 6 cm
The base area = 6^2 = 36
height = 10
Thus,
Volume = 1/3 x 3/6 x 10
Volume = 120 cubic cm

what is the equation for the line that passes through the points (-5.5, 2.5) and (-2.5, -3.5)?
Answer:
y=-2x-8.5
Step-by-step explanation:
y=mx+b
slope = -2
y=-2x+b
y intercept = -8.5

Step-by-step explanation:
A flagpole that is 21 ft tall casts a shadow that is 30 ft long. What is the angle of elevation of the sun when this shadow is cast?
Answer:
34.99°
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
Let angle( X) = angle if elevation
From trigonometry, tan(X)= opposite/ adjacent
Height of the flagpole= 21 ft , which is the opposite side
The base, adjacent side = 30 ft
If we substitute the values we have
Tan(X) = 21/30
Tan(X)= 0.7
Tan-1(0.7)=34.99°
Hence, the angle of elevation of the sun when this shadow will cast is 34.99°

Consider the following pair of equations.
Y = x + 4
Y = -2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write down the solution in (x, y) corn.
Answer:
(- 2, 2 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 2x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 2x - 2 ( add 2x to both sides )
3x + 4 = - 2 ( subtract 4 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Substitute x = - 2 into either of the 2 equations abd evaluate for y
Substituting into (1)
y = - 2 + 4 = 2
solution is (- 2, 2 )

Determine the domain of the following graph
Answer:
See below
Step-by-step explanation:
This is a piecewise function with a domain of (-4,5) and a range of [1,6]. (-4,5) means x can be between -4 and 5, but -4 and 5 can't be included (notated by the parentheses). [1,6] means y can be between 1 and 6 where 1 and 6 are both included in the range (notated by the brackets).

6) 3x+30=90
7) (8x+120)+7x=180
8) 99+3x=180
Solve -3x + 12 = 2x - 18
Answer:
The value of x is 6
Step-by-step explanation:
- 3x + 12 = 2x - 18
12 + 18 = 2x + 3x
30 = 5x
5x = 30
x = 30 ÷ 5
x = 6
Thus, The value of x is 6
