The answers checked for #1, #2, #4, and #5 are correct.
In #3, the constant factor is -3 . So the absolute value of
each term is 3 times the absolute value of the previous one,
AND the signs alternate.

I had this question
Answer:
Step-by-step explanation:
Let G and B be the number of girls and boys.
The ratio boys to girls was 4 to 7.
This means
B/G = 4/7
There were 300 more girls than boys.
This means
G = B+300
Replace in the first equation and solve for B
B/(B+300) = 4/7 ===> 7B = 4(B+300) ===> 7B = 4B + 1200 ===>
===> 7B-4B = 1200 ===> 3B = 1200 ===> B=1200/3 ===> B=400
G = B+300 ===> G = 400 + 300 ===> G=700
Answer:
1. The equation would be y = -2x + 9
Step-by-step explanation:
To find the line parallel going through the given point, first note that parallel lines have the same slope. This means that in #1, we have a slope of -2 in the original line, therefore the parallel line will also have a slope of -2. Now we can use this and the given point to find the line using point-slope form.
y - y1 = m(x - x1)
y - 1 = -2(x - 4)
y - 1 = -2x + 8
y = -2x + 9
Your answer would be a) 60 - x°. This is because angles in a triangle add up to 180°, and as angle B is 90 and angle C is x + 30, that means angle A must be 180 - (90 + 30 + x) which is 180 - (120 + x), which when simplified equals 60 - x. I hope this helps!
