Find the equation of the line that is parallel to the line y=-3x-7 and passes through the point (1,2). Write an equation in slop intercept form
Answer:
y=-3x+5
Step-by-step explanation:
y=-3x-7
slope is -3
parallel lines have the same steepness, they have the same slope. The slopes are equal.
y-y1=m(x-x1)
y-2=-3(x-1)
y-2=-3x+3
y=-3x+3+2
y=-3x+5

A pizza with a diameter of 8 inches costs $10 and a pizza
with a radius of 5 inches costs $12. Which pizza is the
best buy (square inches per dollar)?
Answer:
8 inch is your best buy
Step-by-step explanation:
8inch diameter =10 dollars
5 inch radius = 12 dollars
so if we get each equal to the diameter it should be 10 inch and that would be 24 dollars vs . 8 in for 10 dollars. So best buy would be 8 inch

What is the equation of the line that passes through the point (3,-2) and has a
slope of -22
Answer:
y = -2x + 4
Step-by-step explanation:
slope intercept form:
y = mx + b
m = slope = -2
b = y-intercept
x = x = 3
y = y = -2
Plug in the corresponding numbers to the corresponding variables:
-2 = (-2) * (3) + b
Simplify. First, multiply:
-2 = (-6) + b
Next, isolate the b. Note the equal sign, what you do to one side, you do to the other. Add 6 to both sides of the equation:
-2 (+6) = -6 (+6) + b
b = -2 + 6
b = 4
Plug in 4 for b in the equation:
y = mx + b
y = -2x + 4

Two hamsters work together and move a pile of sunflower seeds in 7 1 2 minutes. How long would it take each hamster to move the same pile alone if one of the hamsters needs 8 more minutes to do the job than the other?
Answer:
Hamster 1: 12 minutes. hamster 2: 20 minutes
Step-by-step explanation:
The first hamster took 8 minutes while the second hamster tool 20 minutes.
Equation
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the time required for the first hamster and y the time for the second hamster.
x = y + 8 (1)
(1/x + 1/y)7.5 = 1
[1/(y + 8) + 1/y ]7.5 = 1
y = 12 minutes
x = 12 + 8 = 20 minutes
The first hamster took 8 minutes while the second hamster tool 20 minutes.

Emiko needs to go to the dentist. It takes her 65minutes to get there by riding her bike. This is 5 minutes shorter than twice the time it would takeby bus. How long does it take Emiko to get to the dentist by bus? a.35 min b.40 min c.45 min d.50 min I will brainliest
65 min by riding her bike
x min by boarding a bus
since the time taken to get to the dentist with a bus is 5min shorter than twice the time taken with a bike, it can be written as
(2x) - 5 = 65
2x = 65 + 5
2x = 70
x = 35 min. (A)

The Vincent family played a game of basketball. For each game, Ben kept a record of the number of 2-point baskets he attempted, and the number of 3-point baskets he attempted. After the family played several games, he made a scatter plot of the data using the 2-point shots as the x-variable and the 3-point shots as the y-variable. The scatter plot has a line of best fit with the equation y=1.2x+3.1
Answer:
your answer is The y-intercept represents how many 3-point shots Ben will try to make if he attempts 0 2-point shots.

3 to the power of negative 4 answer in fraction
Answer:
Step-by-step explanation:
[tex]3^{(-4)}=\frac{1}{3^4}=\frac{1}{81}[/tex]
3 to the power of-4 is equal to the bit 1/81.
To calculate 3 raised to the power of-4 and express the answer as a bit, we can use the fact that a negative exponent indicates the complementary of the base raised to the positive exponent.
In this case
3⁻⁴= 1/3⁴
Now, let's calculate 34 first
3⁴ = 3 x 3 x 3 x 3 = 81
Now, substitute this value back into the complementary expression
1/ 3⁴= 1/ 81
Thus, 3 to the power of-4 is equal to the bit 1/81.

What is the slope of the line? Explain how you calculated the slope in the graph going through the points (-6,-3) and (-2,-8).
Answer:
[tex]\frac{-5}{4}[/tex]
Step-by-step explanation:
Use the slope formula so y2 - y1 / x2 - x1 [the numbers are subscripts]
So -8 - (-3) / -2 - (-6) so -8+3/-2+6, therefore -5/4
