So basycilly slope intercept form is y=mx+b where m=slope and b=y intercept
slope=-1
subsiute
y=-1x+b
y=-x+b
so we are given the point (-3,2)
x=-3 and y=2 is one solution
subsitue and solve for b
2=-(-3)+b
2=3+b
subtract 3 from both sides
-1=b
the slopt inercetp form is y=-x-1
Answer:
Cost =$3
Amount = 8 gallons and 17 gallons
Step-by-step explanation:
Given
24 + 51
Required
Simplify to show the cost and amount of gas bought by each individual
24 + 51
[Factorize]
3(8 + 17)
The above can't be factored any further.
Since the cost of gas for both individuals is the same, we can conclude the following.
Cost = $3
This is so because it applies to both numbers in brackets
Amount of Gas = 8 gallons and 17 gallons respectively by both individuals
Answer:
x^4 +8/7x^3 + 6x +1
Step-by-step explanation:
8/7x^3 + x^4 + 6x +1
Standard from is from the largest power to the smallest power
x^4 +8/7x^3 + 6x +1
The amount of plywood needed to build the garbage bin is the surface area. Therefore, the amount of plywood needed is 90884 cm².
<h3>How to find the surface area of a rectangular prism</h3>
The wooden box is a rectangular prism. The amount of plywood used to construct the wooden box is the surface area of the box.
Therefore,
surface area of rectangular prism = 2(lw + lh + hw)
where
- l = length
- w = width
- h = height
l = 156 cm
w = 122 cm
h = 95 cm
surface area of rectangular prism = 2((156 × 122) + (156 × 95) + (122 × 95))
surface area of rectangular prism = 2(19032 + 14820 + 11590)
surface area of rectangular prism = 2(45442)
surface area of rectangular prism = 90884 cm²

Step-by-step explanation:
<u>Q1</u>
- y = (x + 3i)(x - 7)
- y = x² + 3ix - 7x - 21
- <u>y = x² + (3i - 7)x - 21</u>
<u>Q2</u>
- y = (x - √5)(x - i)
- y = x² - √5x - ix + √5i
- <u>y = x² - (√5 + i)x + √5i</u>
