Slope is
Then you use the equation
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
You know m (from above) and now you can solve for b.
Rearrange terms:
And that will be the answer.
Make sense?
4x + 24x - 2 = 7(4x + 2)
Distributive property.
4x + 24x - 2 = 28x + 14
Combine like terms.
28x - 2 = 28x + 14
Like terms cancel
-2 = 14
0 = 16
<h3>The equation is false and has no solutions.</h3>
Answer:
Step-by-step explanation:
Let the number of hours Nick does the job alone to be x - 3 hours
Hence, in 1 hour, Nick has done 1/x - 3
Together they complete the job in 9 hours
Hence, let's represent the job as 1
9/x + 9/x - 3 = 1
Multiply through by (x)(x-3)
9(x- 3) + 9(x) = 1
9x - 27 + 9x = (x)(x-3)
-27 = x² - 3x
x² - 3x +27 = 0
Answer:
The answer is2nd point
Step-by-step explanation:
(x^4/3)×(x^2/3) = x^(4/3 + 2/3)
= x²
(x²)^1/3 = x^(2×1/3)
= x^2/3
Answer:
y ≥ -x +2
Step-by-step explanation:
The solid line has a slope of -1 and a y-intercept of 2, so its equation in slope-intercept form is ...
y = -x +2
The shaded area is above this line, and the line is part of the solution set, so we want an inequality that has "y" and the comparison symbol in this order: "y ≥" or "≤ y".
We already have an equation with "y" on the left, above, so we just need to introduce the comparison symbol:
y ≥ -x +2
Another way to write this is ...
x + y ≥ 2
