To solve this it would have to be equal to something
Translations to the left and right take the form f(x-s), where s is the value of the shift. Note that shifts in the positive (right) direction appear negative, and shifts in the negative (left) direction appear positive. It's common to mistake these, so memorize the rule! In this case, the shift becomes f(x-4) = -3(x-4). A vertical stretch takes the form of k*f(x), where k is the value of the stretch. This stretch would appear as 4*f(x) = 4(-3x). Combining these transformations would yeild 4*f(x-4) = 4[-3(x-4)]. Simplify for the final result.
Its c 3 Bro chelck it out thats correct
Answer:
Step-by-step explanation:
Supplementary angles mean the angles add up 90 degrees.
So, 4x + 18 + 2x + 12 = 90.
Combine like terms...
6x + 30 = 90
Subtract 30 from both sides.
6x = 60
Divide by 6
x = 10
Then to find the measure of angles RST, we plug in 10 for x.
4(10) + 18 = RST
RST = 40 + 18
RST = 58
Subtract the 4 from both sides which makes the answer x=20
