Answer:
8
Step-by-step explanation:
replace x with 4 and y with 2 in the equation
3x - 7y + 10
3(4) - 7(2) + 10
multiply
12 - 14 +10
add
-2 + 10 = 8
Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
Hope this helps! :)
Answer:
Step-by-step explanation:
We know that the line has a slope of 2 and it passes through the point (3, -4).
So, we can use the point-slope form:
Where m is the slope and (x₁, y₁) is a point.
So, let’s substitute 2 for m and (3, -4) for (x₁, y₁). This yields:
Solve for y. Distribute the right:
Subtract 4 from both sides. Therefore, our equation is:
