Answer:
Divide by -4 on each side and flip the sign. Can you give brainliest???
Step-by-step explanation:
You have to divide -4 into both sides in order to isolate the variable. Then flip the sign because you are dividing by a negative number. Whatever you do on one side, you also do to the other.

The points (15,36) and (30,72) form a proportional relationship. Find the slope of the line through
the points. Then use the slope to graph the line.
The slope is
(Simplify your answer.)
Answer:
[tex]\frac{18}{5}[/tex]
Step-by-step explanation:
Given coordinates;
(15,36) and (30,72)
Unknown:
Slope of the line = ?
Solution:
(15,36) and (30,72);
Slope is the rise divided by the run. To find the slope, we use the expression below;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
y₁ = 36
y₂ = 72
x₁ = 15
x₂ = 30
Insert the parameters and solve;
Slope = [tex]\frac{72 - 36 }{30 -15}[/tex] = [tex]\frac{36 }{15}[/tex]
Slope = [tex]\frac{18}{5}[/tex]

3. Which interval represents the range of the function h(x) = 2x2 - 12x + 13 ?
use the defintion of the derivative to find the derivative of the given function. f(x)= 5 square root of x
Answer:
The derivative of function [tex]f(x)=5\sqrt{x}[/tex] is [tex]\frac{5}{2\sqrt{x} }[/tex]
Step-by-step explanation:
We need to find derivative of the given function [tex]f(x)=5\sqrt{x}[/tex]
Finding the derivative:
[tex]\frac{d}{dx}(5\sqrt{x} )[/tex]
Using the rule (a.f)' = a(f)', taking out constant value 5
[tex]=5\frac{d}{dx}(\sqrt{x} )[/tex]
We know [tex]\sqrt{x} =x^{\frac{1}{2}[/tex] Replacing [tex]\sqrt{x}[/tex]
[tex]=5\frac{d}{dx}(x^{\frac{1}{2}} )[/tex]
Applying derivative rule: [tex]\frac{d}{dx}(x^a)= a.x^{a-1}[/tex]
[tex]=5\times\frac{1}{2}(x^{\frac{1}{2}-1} )\\=\frac{5}{2}(x^{-\frac{1}{2}} )\\=\frac{5}{2x^{\frac{1}{2}}}\\=\frac{5}{2\sqrt{x} }[/tex]
So, the derivative of function [tex]f(x)=5\sqrt{x}[/tex] is [tex]\frac{5}{2\sqrt{x} }[/tex]
Jimmy borrowed $450 to start a lawn-mowing business. He charges $35 per lawn and it costs him $8 in operating costs per lawn.
What is the y-intercept of the line representing Jimmy's costs?
Answer: $450
Step-by-step explanation:
Given that:
Amount borrowed = $450
Amount charged per lawn = $35
Operating cost per lawn = $8
Jimmy's cost (C(x)) :
Amount borrowed + operating cost
If x lawns are mowed :
$450 + $8 per lawn
$450 + $8x
C(x) = 450 + 8x
Intercept (value of y when x = 0
Value of C(x) ; when x = 0
C(x) = 450 + 8(0)
C(x) = 450 + 0
C(x) = 450

Evaluate the formula for the given values of the variables.
d = rt; r = 54 miles per hour, t = 3 hours
O d = 324 miles
O d = 18 miles
O d = 162 miles
O d = 57 miles
Answer:
d=162 miles
Step-by-step explanation:
The formula is d=rt, so the distance is the rate multiplied by the time. Thus, it is 54 times 3 or 162.
Mila is deciding between two parking garages. Garage A charges an initial fee of $7 to park plus $4 per hour. Garage B charges an initial fee of $3 to park plus $5 per hour. Let AA represent the amount Garage A would charge if Mila parks for tt hours, and let BB represent the amount Garage B would charge if Mila parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.
Answer:
I would do B
Step-by-step explanation:
It is cheaper
Answer
A=4t+7
B=B= 5t+35t+3
Step-by-step explanation:
Garage A is cheaper than Garage B when tt > 4 hours.
1. Olivia has read 40 pages of a 70-page book. What percent of pages has Olivia read? (Round your answer to the nearest tenth). A. 40% B. 42.9% C. 57.196 D. 28%
If Olivia has read 40 pages of a 70-page book. Then 57.196% of pages has Olivia read
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Olivia has read 40 pages of a 70-page book.
We need to find percent of pages has Olivia read
Let x be the percent of books olivia read.
This can be done by 70 x=40
Divide both sides by 70
x=40/70
x=0.5719
Now multiply this with 100
0.5719×100
57.196

Mr. Jones has 3/4 cup of fertilizer. He will use a 1/8 cup measuring scoop to pour all of the fertilizer onto his plants. How many times will Mr. Jones fill the measuring scoop with fertilizer? Write your answer in the box.
Answer:
6 times
Step-by-step explanation:
We will have to divide in order to solve this problem.
[tex]\frac{3}{4}[/tex]÷[tex]\frac{1}{8}[/tex]
We will have to find the reciprocal of 1/8, which is basically flipping it, so it is 8.
After, we will have to multiply 3/4x8. The product would come out as 24/4, and if you simplify it, the answer will be 6 times.
