Answer:
B. 8x - 3
C. 8x + 12
Step-by-step explanation:
64 is a perfect square, meaning it has two factors that are identical (8), and 36 is also a perfect square, but in this case, you don't see two 6's in the answer choices.
12 and -3 give you a product of -36, so your answer choices would be:
(8x - 3) (8x + 12)
If you're unsure, you can multiply them together to check if they come out to the unfactorized expression.
Answer:
First option, y = 2x - 3
Step-by-step explanation:
Remember the formula for a line is y=mx+b, where m is slope (slope = rise/run) and b is y-intercept (y-intercept is the point that crosses the y-axis)
Since the line on the graph crosses the y-axis at -3, that will be the y-intercept. Starting from that point, find another point. In this case you go upwards 2 units and to the right 1, so your slope will be 2/1 or just 2 .
Hope this helped :)
1) start with (x-h)^2 + (y-k)^2 = r^2. Insert the given info: center at (-1,8) and radius 5:
(x+1)^2 + (y-8)^2 = 5^2 (answer)
<u> 70</u> =<u>63</u><u>
</u>100 ?
cross multiply 63 and 100= 6300 then divide by 70= 90
