Answer:

B. y=6x+9

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-3)/(-2+1)= (-6)/(-1)= 6

m=6

y=mx+b y=6x+b

plug in one of the points for b

-3=6(-2)+b -3=-12+b -3+12= 9

y=6x+9

First you have to find the slope of the line

m = y2-y1/x2-x1

m = -3 - 3/-2 - -1

m = -6/-1

m = 6

then using the y = mx +b

3 = 6(-1) + b

3 = -6 + b

9 = b

y = 6x + 9 B is the answer

Answer:

NOR = 126.6

Step-by-step explanation:

one full circle would have 360 degrees

so we can make an equation that shows all of our angles adding up to 360:

NOQ + QOR + NOR = 360

we know that NOQ is 147.7

we know that QOR is 85.7

substitute these into our equation:

147.7 + 85.7 + NOR = 360

add like terms:

233.4 + NOR = 360

subtract 233.4 from both sides:

NOR = 126.6

97) If the average of 3a and 4b is less than 50 and a is twice b, what

oee [108]

The average of $3a$ and $2b$ satisfies

$\dfrac{3a+4b}2$

Then

$a=2b\implies\dfrac{3(2b)+4b}2=5b$

$a=2b$ , so if $a$ must be an integer, then the largest integer value it can take on is 19 if $b$ can be a rational number (in which case $b=9.5$ ) or 18 if $b$ must also be an integer.

Given that none of the provided answer choices lists 18 or 19, I'd bet there's a typo and you're supposed to find the maximum integer value of $b$ , in which case the answer would be B as the largest integer value would be 9.

The ratio of boys to girls at the beach cleanup was 7:8. If there were 42 boys, how many girls were there?

lesantik [10]

It would be 48 girls. 42 divided by 7 equals 6 so then you just times 6 by 8 to figure out how many girls there will be.

You have $3000 to enclose a rectangular piece of property with a fence. The fence costs $9 per foot. A scale drawing of the prop

son4ous [18]

Answer:

Step-by-step explanation:

C=9P

P=2(L+W)

C=18(L+W)

C=18(8(12)+7(12))

C=18(96+84)

C=18(180)

C=$3240

So you do not have enough money to enclose the property.
