Answer:
- 10
Step-by-step explanation:
Order of operations: PEMDAS
Multiply first then add
-4 + -6 = -10
Answer:
x-12≤7
x≤19
Step-by-step explanation:
less than means it comes after
x-12
is at most means less than or equal to
x-12≤7
Add 12 to each side
x-12+12≤7+12
x≤19
A) You would use the two points that are closest to the graphed line
(2,7) and (8,13)
B) Slope = change in Y over the change in X:
Slope = (13-7) / (8-2) = 6/6 = 1
Slope = 1
c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.
Equation is: y-7 = x-2
d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.
To isolate Y add 7 to both sides:
y = x +5
The result of division is 21.392
Rounded to the nearest tenth its 21.4 answer
(because the hundredth digit is 9 so you add 1 to the tenth digit.)
4 - 5x = 2x + 25
4 = 7x + 25
-21 = 7x
-3 = x
4 - 5x + 2x + 25 = ac
4 - 5(-3) + 2(-3) + 25 = ac
4 - (-15) + (-6) + 25 = ac
19 + (-6) + 25 = ac
38 = ac
