Answer:
107
Step-by-step explanation:
We first need to input the values of the variables.
7 + 2 x 5^2
7+10^2
7+100 = 107
Answer:
D) 180 miles / 6 gallons
Step-by-step explanation:
180 / 6 simplified is 30 / 1. Although C has the same numbers, the numbers are switched. 6 / 180 simplified would be 1 / 30. This is not the same as 30 / 1.
by using Pythagoras theorem,
third side will be either 8^2+5^2=sqrt(64+25)=sqrt(89)=9.43 or
8^2-5^2=sqrt(64-25)=sqrt(39)=6.24
the difference is=9.43-6.24=3.19inches i think this is it i may have messed up
Answer: -2x+3y = 21 which is choice C
============================================
Work Shown:
The slope of the original line is -3/2. The perpendicular slope is 2/3. We flip the fraction and flip the sign. Multiplying the original slope (-3/2) and the perpendicular slope (2/3) will result in -1. Let's use this perpendicular slope and the point to find the equation of the perpendicular line in slope intercept form.
y = m+b
y = (2/3)x+b .... plug in the perpendicular slope
9 = (2/3)(3)+b .... plug in the point (x,y) = (3,9)
9 = 2+b
9-2 = 2+b-2 ... subtract 2 from both sides
b = 7
So y = (2/3)x+b turns into y = (2/3)x+7.
This equation is in slope intercept form.
---------------------------
Let's convert to standard form
y = (2/3)x+7
3*y = 3*((2/3)x+7) ... multiply both sides by 3 to clear out the fraction
3*y = 3*(2/3)x+3*7 ... distribute
3y = 2x+21
-2x+3y = 21 .... get the x term to the other side (subtract 2x from both sides)
