Answer:
Hope this helps! (:
Step-by-step explanation:
By putting the numbers in the given equation,
2x + 3 + 3x = 7x + 9
5x + 3 = 7x + 9
(5x + 3) - 7x = (7x + 9) - 7x
(5x - 7x) + 3 = 9
-2x + 3 = 9
(-2x + 3) - 3 = 9 - 3
-2x = 6
-x = 3
x = -3
Therefore, our equation is correct which has a negative result.
In place of 6 if we use 8, value of x will be negative again.
Answer:
The slope is 0.
Step-by-step explanation:
You could draw it on graphs paper . It will be a horizontal line passing through the point (0,4). y will always be 4 and x can be any value.
The slope of a horizontal line is 0.
Answer:
y = -5/2x - 4
Step-by-step explanation:
(0,-4) and (-4,6)
Slope:
m=(y2-y1)/(x2-x1)
m=(6+4)/(-4-0)
m=10/-4
m= -5/2
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = -5/2(x - 0)
y + 4 = -5/2x
y = -5/2x - 4
30000mm÷10=3000cm
3000cm÷100=30m
Answer: 30m
Answer:
20
Step-by-step explanation:
h(-7) just means that inside the x value, you replace the x with a -7.
h(-7) = |3x| - 1
h(-7) = | 3(-7)| - 1
h(-7) = | -21 | - 1
NOTE: -21 is inside |x|, those straight lines mean absolute value. No matter what, any negative number would turn into a positive one. And if it’s posititve, then it stays positive.
h(-7) = 21 - 1
h(-7) = 20
