If the points are (-10, 3), (-2, 10) what is the slope?
Answer:
= 7/ 8
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 10-3)/( -2 - -10)
= ( 10-3)/( -2 +10)
= 7/ 8

A map is drawn using a scale of 1cm/80 mi
Two cities are 280 miles apart
How far apart are the cities on the map?
Answer:
280/80 = 28/8 = 7/2 = 3.5 cm
Step-by-step explanation:
the ratio is 1cm/80mi = a cm/280mi
so you get 280cm * mi = 80mi*a cm
so a = 280/80 = 3.5

does the point (2, 5) lie on the line y = 3x-1
The solution is Yes
The point P ( 2 , 5 ) lies on the equation of line y = 3x - 1
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = 3x - 1 be equation (1)
Let the point be represented as P
The coordinates of P is = P ( 2 , 5 )
Substituting the values of x and y in the equation , we get
y = 3x - 1
when x = 2 and y = 5 , we get
5 = 3 ( 2 ) - 1
5 = 6 - 1
5 = 5
Therefore , the solution is true
Hence , the point P ( 2 , 5 ) lies on the equation of line

Are the two ratios relationships below equivalent? Explain why or why not.
3 pink umbrellas to 21 green umbrellas
and
6 pink umbrellas to 36 green umbrellas
Answer:
No
Step-by-step explanation:
Find the unit rates, meaning how many green umbrellas per pink umbrella? So we have 2 ratios:
1. 3:21
2. 6:36
For the first ratio, divide both sides by 3 to find how many green umbrellas per pink umbrella. 1:7
Do the same for the second one, 1:6. So they are different.

Answer:
Question 7: Company A has a lower rate
Question 8: Caiden's vehicle gets more miles per gallon
Step-by-step explanation:
Question 7:
According to the table for Company B's rates, if you divide the total cost by the square footage in each row, you would get $2.75/ft² each time. Therefore, Company A would charge the Smiths a lower cost per square foot.
$2.25/ft² < $2.75/ft²
Company A < Company B
Question 8:
Using the given equation, we already know that Caiden's vehicle has a gas mileage of 16.2 miles/gallon The graph for Ethan's gas mileage can be figured out using slope. Taking the points (0, 0) and (2, 30) on the line, we can figure out the line's slope.
slope = rise/run,
where "rise" is how much you add or subtract to get from the first y-value to the second, and "run" is how much you add or subtract to get from the first x-value to the second.
slope = rise/run
slope = 30/2
slope = 15/1
The slope of the line is 15, so that means the line's equation is y = 15x. Therefore, Ethan's gas mileage is 15 miles/gallon.
16.2 mpg > 15 mpg
Caiden > Ethan
f(g(x))
F=3x-2
G=-x+1
Answer:
f(g(x)) = 3x + 1
Step-by-step explanation:
To find f(g(x)), substitute x = g(x) into f(x), that is
f(x + 1)
= 3(x + 1) - 2
= 3x + 3 - 2
= 3x + 1
