Answer:
y = - 2x + 9
Step-by-step explanation:
From y = -2x + 1
comparing with y = mx + c
slope (m) = - 2
Writing in point slope form
y - y1 = m(x - x1)
y - 1 = -2( x - 4)
y - 1 = -2x + 8
Now writing in slope intercept form
y = - 2x + 8 + 1
y = -2x + 9
Hope it will help :)

Find the surface area of the prism.
The surface area is square millimeters.
Answers
Answer:
57.1mm^2
Step-by-step explanation:
4*4=16
16/2=8mm^2 cross section
(4*3) + (4*3) + (5.7*3) = 41.1mm
8*2=16
41.1+16=57.1mm^2
The surface area of the prism is S = 57.1 mm²
What is the surface area of the prism?The surface area of the prism is calculated as
The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism
Surface Area of the prism = 2B + ph
The area of the triangular prism is A = ph + ( 1/2 ) bh
Given data ,
Let the area of the 2 triangles be T
Let the area of the 2 rectangles be R
Let the area of the third side be U
Now , the total surface area of the prism = T + R + U
where T = 2 x ( 1/2 ) ( 4 x 4 )
T = 16 mm²
R = 2 x ( 3 x 4 )
R = 24 mm²
And , U = 5.7 x 3
U = 17.1 mm²
Therefore , the total surface area of prism S = 16 mm² + 24 mm² + 17.1 mm²
S = 57.1 mm²
Hence , the surface area of prism is S = 57.1 mm²

Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310
Answers
Answer:
[tex]60c + 85s \geqslant 310[/tex]
Step-by-step explanation:
He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.
The required inequality:
60x + 85y >= 310
What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given, a person gets paid $60 to detail a car and $85 to detail an SUV.
Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.
Then, the amount earned by detailing x cars and y SUVs can be expressed as:
60x + 85y
According to the problem statement, he wants to earn at least $310, so we can write the inequality:
60x + 85y >= 310
This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.

Step-by-step explanation:
When Dividing fractions, use the reciprocal of 3/4
7 1/2 times 4/3 equals
10
Answer:
10
Step-by-step explanation:
You would do something called KCF Keep, Change, and Flip.
You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.
15/6 times 4/3. 15 x 4 = 60
2x3= 6
so I can be 60/6 but you would simplify and 6 goes into 60 10 times. so 10 is you answer

After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?
Answers
Answer:
D
Step-by-step explanation:
The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.
