Answer:
y = -5x - 8
Step-by-step explanation:
Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.
Now plug in your points
Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.
Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept
2 = -5(-2) + b (b represents the y-intercept)
2 = 10 + b (subtract 10 from both sides)
-8 = b
The perpendicular line looks like this y = -5x - 8
Hope this helps ya! Keep smiling!
O si it told me that the solution was -1/2,x2 and it equals =1/2 hope it helps
Answer:
ft tall
Step-by-step explanation:
We must follow the indications:
Ryan is 4 1/2 ft. tall.
Ryan = 
He is 3 in. taller than his sister Lizzie. to find how tall is Lizzie we need to substract 3 inches from the height of Ryan, but we can only substract the quantities if they are in the same units.
Thus we convert the 3 inches to feet, since we 1 feet = 12 inches:
so the height of lizzie:
we convert the first mixed number to fraction by multiplying 4 by 12 and adding the numerator 1:
the subtraction becomes:
Lizzie is 23/6 ft tall.
She is 3/4 of a foot taller than her sister Emma, thus we must substract 3/4 from the height of Lizzie to find the height of Emma:
Emma is ft tall.
Answer: 0
Step-by-step explanation:
Given: The temperature was 75 ( units) at noon the temperature increased by 7 by evening to decreased by 7.
I.e. Change in temperature = Increase in temperature - decrease in temperature
=7-7 = 0
Hence, the net temperature change is 0. (Original temperature of 75 (units) remains at the end )
Answer:
Domain x<5
Range all real numbers
Step-by-step explanation:
log (5-x)
(5-x) > 0
subtract 5
-x> -5
x<5
