It is really simple. The ratio between both the triangles is 7, so you just divide 49 by 7(it gives you 7) to get the value of x. The answer is option (a) 7.
Hope This Helped!
Good Luck!
Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24
Answer:
Step-by-step explanation:
We are given the two functions:
And we want to find:
This is equivalent to:
By substitution:
Rearranging yields:
Combine like terms:
Hence:
Answer:
x = -4
Step-by-step explanation:
with x = -4 , a perpendicular line at -4 on the x axis reveals that x is alway -4...all the way along the perpendicular line. Y will be changing values as the perpendicular line goes up or down
