Answer:
(0, -6)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Write standard form
3x - 7y = 42
Step 2: Rewrite in slope-intercept form
Subtract 3x on both sides: -7y = 42 - 3xDivide both sides by -7: y = -6 + 3/7xRewrite: y = 3/7x - 6Step 3: Find y-intercept
b = -6
Answer:
(0, -6)

8. Calculate the length of r or st
9514 1404 393
Answer:
30 miles
Step-by-step explanation:
The Law of Sines is used for this purpose. The angle at R is the difference ...
180° -(23° +34°) = 123°
Then the length r satisfies ...
ST/sin(R) = RT/sin(S)
ST/sin(123°) = (20 mi)/sin(34°)
ST = (20 mi)sin(123°)/sin(34°) ≈ 30.00 mi
The length of r or ST is 30 miles.

Hanna says you cannot represent the fraction 1/4 on the number line.
Answer:
The answer is D; Hanna is not correct,. The fraction 1/4 is equal to 2/8, so you can graph it on the second tick mark to the right of zero.
Step-by-step explanation:
Because the number line is broken up into 8 parts, the points on the graph are, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 8/8 (also known as one)
1/4 = 2/8. We know this because if we multiply 1/4 by 2, we get 2/8.
So, because 2/8 is the same as 1/4, we know that Hanna is not correct, and that you can graph 1/4 on this number line, because it is the same as 2/8.
I hope that this helps :)

Rewrite 56 + 32 as the product of the GCF and a sum.
Answer:
8(7 + 4)
Step-by-step explanation:
The GCF of 56 and 32 is 8 , thus
56 + 32 = 8(7 + 4 )
56 + 32 = 88
8(7 + 4) = 8 × 11 = 88

- 9/14 over 2/7 in simplest form step by step
Answer:
-63/28 or 2 1/4
Step-by-step explanation:
when dividing you will be multiplying by the reciprocal of the second fraction. SO it will be...
-9/14 times 7/2
this is... -63/28
Answer:
-9/4
Step-by-step explanation:
-9
