Answer:
643
Step-by-step explanation:
Answer:
y =
x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (10,12) ← 2 ordered pairs from the table
m =
=
= 
y =
x + c ← is the partial equation
to find c substitute any ordered pair into the partial equation
using (6, 10 ), then
10 = 3 + c ⇒ c = 10 - 3 = 7
y =
x + 7 ← linear equation
Answer:
complementary angles, x=19
Step-by-step explanation:
since the two parts of the angle add up to 90, they are complementary angles.
you can find x by adding them and setting it equal to 90:
3x-2+2x-3 = 90
5x-5 = 90
5x = 95
x = 19
Answer:
x=0,1,-1
Step-by-step explanation:
It factors as
X(x+1)(x-1)=0
Answer:

Step-by-step explanation:
Using the division rule when dealing with exponents

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.
so using that we are going to do 2, 4 and 9



Combine all the terms and we get
