170 divided by 80 is 2.125, so 80 goes in 170, 2.125 times
y = 2x - 5
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x - y = 6 into this form ( subtract 2x from both sides )
- y = - 2x + 6 ( multiply through by - 1 )
y = 2x - 6 ← in slope -intercept form with slope m = 2
Parallel lines have equal slopes
the partial equation is y = 2x + c
to find c substitute (2, - 1 ) into the partial equation
- 1 = 4 + c ⇒ c = - 1 - 4 = - 5
y = 2x - 5 ← equation of parallel line
Answer:
Angle 8
Step-by-step explanation:
Supplementary angles are angles that are equal to 180 degrees.
Answer:
6
Step-by-step explanation:
Let Nancy's age be represented by n
Because Isabel is 3 times as old as Nancy, her age would be represented by 3n
Sum of their ages = 24
n + 3n = 24
4n = 24
divide both sides of the equation by 4 to determine n
n = 6
The formula that we want to use here is S = D/T.
S = Speed
D = Distance
T = Time
So, we know that S = 550 and T = 3.5, so we can plug them in.
We get 550 = D/3.5
Multiply by 3.5 on each side, and you figure out that the plane has traveled 1925 miles.
