Answer:
1: y intercept = 5
2: y interpcept = -2
3: y intercept = -3
Step-by-step explanation:
So for the 1st and 3rd ones (the graphs), all you have to do is find which y matches the x value of 0
The 2nd one is a bit harder. I’ll explain it the best I can
So in the y section, you see that -4 goes to -3 when the x is raised by 1. There for everytime the x raises by 1, so does the y. That means when x = 0, the y = -2
Answer:
Two equal sides = 14.4 inches each
Shortest side = 7.2 inches
Step-by-step explanation:
a + b + c = 36
a = b
a = 2c
then:
c = a/2
a + a + a/2 = 36
2a + a/2 = 36
4a/2 + a/2 = 36
5a/2 = 36
a = 2*36/5
a = 72/5
a = 14.4
a = 2c
14.4 = 2*c
c = 14.4/2
c = 7.2
a = b
b = 14.4
Check:
14.4 + 14.4 + 7.2 = 36
Step-by-step explanation:
Substitute variables with given values
Minus sign becomes plus sign if a negative is multiplied by a negative or a negative is put next to a negative number.
4x-7y=4(-5.2)-7(-6.8)
-20.8+47.6=26.8
9t - 3t + 4
= 6t + 4
(hence 9-3)
you can do this due to the t being the same unit (classified as a like term). if it were 9t - 3g + 4, it would have to stay the same.
3√5 / 4√5 The √5's cancel out
The answer is 3/4
This is because √5 is in both the denominator and the numerator, and so you can pull them both out.
