Answer:
11.05
Step-by-step explanation:
2x-5=18
2x+5=23
2x/2=2/23
x=11.05
Answer:
y = -3/4x + 7/4
Step-by-step explanation:
use the boins to find the slope in the equation y2 - y1/x2 - x1
4 - -2/-3 - 5 = 6/-8 or 3/-4
plug that into the equation: y = mx + b
m = slope b = y-intercept
y = 3/-4x + b now plug in one of the points ex) (5, -2)
(-2) = 3/-4 (5) + b now solve to find the y-intercept: B
b=7/4
now to check your answer plug the other point into the original equation (I have already done this the y-intercept is b=7/4)
here is your final equation y = 3/-4x + 7/4
Answer:
your number is 30
Step-by-step explanation:
x ÷ 3 - 4 = 6
x = 30
