Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
The formula of a slope:
We have the point <em>(4, 12)</em>, and y-intercept <em>b = -2 → (0, -2)</em>.
Substitute:
Finally:
You can solve this problem by writing an equation of ratios and finding the value of the unknown that way:
10 ft 17 ft
---------- * ---------
50 ft x
Then 10x = 850, and so x = 85 feet.
Answer:
C.
Step-by-step explanation:
(3x-2)*(4x-7)
12x^2 - 21x - 8x + 14
(12x^2 - 29x + 14) square units
Final answer: C
Answer: x = -1
Step-by-step explanation:
2x - 6 + 17 = 9
Subtract 17 from both sides
2x - 6 = -8
Add 6 to both sides
2x = -2
Divide by 2 on each side
x = -1
