Slope that is passing through (3,5) and (0,-7)
Answer: 4
Step-by-step explanation:
Slope: [tex]\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]
y₂ = -7
y₁ = 5
x₂ = 0
x₁ = 3
[tex]\frac{-7 -5 }{0- 3 }=\frac{-12}{-3} = \frac{4}{1} = 4[/tex]

It takes 2 ounces of paint to completely cover all 6 sides of a rectangular prism box
which holds 15 cups of sugar. Double the dimensions of the box. Approximately how
much paint would the new box need? How much sugar would it hold?
Answer:
120 cups of sugar
8 ounces of paint
Step-by-step explanation:
Given that :
To cover all sides of the rectangular prism with paint, that is the surface area.
The amount of sugar held by the prism is function of its volume.
Hence, doubling the dimension :
The surface area, in unit² is a obtained by
Initial paint required * 2^2
2 * 2² = 2 * 4 = 8 ounces of paint.
For sugar :
It has to do with volume, unit³
Initial * double³
15 * 2³
15 * (8) = 120 cups of sugar

-3x + y= – 8
3x + 2y = – 13
X =?
y =?
Answer:
x=1/3
y=-7
Step-by-step explanation:
using the elimination method, you can add both equations vertically, to eliminate the x
-3x+y=-8
3x+2y=-13
3y=-21
y=-7
we then fix the value of y into the first equation
-3x+y=-8
-3x-7=-8
-3x=-8+7
-3x=-1
x=1/3

The perimeter of a square can be found using the formula P = 4s where s is the side length of the square. If you were to increase the length s by 11, the
expression for the perimeter would become 4/5 + 11). Expand the expression to represent the perimeter of the larger square.
Which expression represents the perimeter of the larger square?
O A. 4s +11
O B. 45 +44
O C. 5s + 15
O D. S +44
Answer:
Step-by-step explanation:
Are you scanning the question?—because there are some errors. If the length of a side is increased by 11, the expression for the perimeter would become
4(s+11)
not 4/5+11)
4(s+11) = 4s+44
The answer is B, which should read 4s+44, not 45+44
The perimeter of a square is 4s+44. So option (B) is the correct option.
What is the perimeter?The perimeter of a square is the total length of all the sides of the square. Hence we can find the perimeter of a square by adding all its four sides.
For the given situation,
The perimeter of the square is given by the formula, P = 4s
where, P is the perimeter and s is the side of the square
The length of the square is increased by [tex]11[/tex]
So, the perimeter becomes [tex]p=4(s+11)[/tex]
⇒[tex]p=4s+44[/tex]
Hence we can conclude that the correct option is (B) 4s+44.

A game show contestant cannot spend more than $100 on $0.79 cans of beans and $3.59 boxes of cereal. Which inequality represents the situation, where b is the number of cans of beans and c is the number of boxes of cereal?
Answer:
i believe it would be 0.79b + 3.59c [tex]\leq[/tex] 100
Step-by-step explanation:
the price of the number of cans of beans added to the number of boxes of cereal must be less than or equal to $100
0.79b represents the price of the beans multiplied by the amount of cans the contestant buys, and 3.59c represents the price of the cereal multiplied by the amount of boxes the contestant buys

3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0
Answer:
a = 4 , b = -2
Step-by-step explanation:
3a + b = 10
2a + 4b = 0
(By using elimination method, eliminate one variable) - to get only one equation
(3a + b = 10 ) 4
2a + 4b = 0
12a + 4b = 40
(minus)
2a + 4b = 0
10a = 40
a = 40/10
a = 4
(substitute a into an equation to get b)
2a + 4b = 0
2(4) + 4b = 0
4b = 0 - 8
b = -8/4
b = -2

Answer:
b) [tex]f^-1(x)[/tex]= ∛(4x-24)
c)2
Step-by-step explanation:
these ones are inverse functions
change the f(x) for y and make x the subject
y= x³/4 +6
(y-6)x 4 = x³
∛(4y-24)= x
then put x back were y is
[tex]f^-1(x)[/tex]= ∛(4x-24)
and to do c just put in 8 where x is
∛(4(8)-24)= 2
