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 )
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)

A dresser has a width of 6 feet, a height of 3 feet, and a depth of 2 feet. If the dresser has 6 drawers of the same size, what is the volume of the space for each drawer?
Answer:
The volume of the space for each drawer is 6 feet^3.
Step-by-step explanation:
Solve for the volume of the entire dresser.
Formula for volume of a rectangle:
Volume (v) = Length (l) × width (w) × height (h)
v = 2 × 6 × 3
v = 12 × 3
v = 36
Now divide the volume by the number of drawers.
36 ÷ 6 = 6

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

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
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
y = -2x-8.5
In AQRS, the measure of ZS=90°, the measure of ZQ=64°, and RS = 16 feet. Find the length of QR to the nearest tenth of a foot.
Answer:
17.8
Step-by-step explanation:
Using the SOH CAH TOA identity
Opposite = 16
Hypotenuse = QR = x
Angle of elevation = 64 degrees
Sin64 = opp/hyp
Sin 64 = 16/x
x = 16/sin64
x = 16/0.8898
x = 17.8
Hence QR is 17.8 to the nearest tenth of a foot
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°

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].
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

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).
