Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.

Answer:

When you are finding a line that is perpendicular, you need to look at the slope. In the format, y=mx+b, the m represents the slope. In this case, the slope (m) of the line is -1/9. A line with a perpendicular slope is the negative inverse. The negative inverse for -1/9 is 9/1. Once you know the slope, you can begin to plug in the new information in order to find the new b (y intercept).

New Line information:

m=9/1, (2,-5) --> this means that x = 2 and y = -5

y=mx+b

-5 = 9/1(2) + b

-5 = 18 + b

-23 = b

Once you find the b, you plug the b and m into the equation y = mx + b

y = 9/1x -23

Answer:

B. There is 1 boy for every 6 girls in the class.

Step-by-step explanation:

Since the ratio is 1 boy per 6 girls and we don't know how many students there are then B is the best answer

hope this helped :))

Answer:

B. There is one boy for every 6 girls in class.

Step-by-step explanation:

When you have a ratio, it compares two numbers. When you have a ratio 1:6 the colon  there can be read as "is to" or "for every".  

That means that ratio can be read as 1 is to 6 or "there is 1 for every 6."

In this case 1:6 represents the number of boys to the number of girls to class. This means that there is 1 boy for every 6 girls in class.

Answer:

73

Step-by-step explanation:

7^2 = 49

Order of operations, parenthesis first.

3*4 = 12

5*12 = 60

49+60 = 109

6^2 = 36

109-36 = 73

Answer:

1.) 73

2.) x+x+x+y+y = 2y + 3x

2(x+2y) = 2x + 4y

x+x+y+y = 2x + 2y

Answer:

I think y=1x+2

Step-by-step explanation:

y=mx+c

m=(y2-y1)/(x2-1)

I just chose (0,2) and (-3,-1)

-1-2=-3

-3-0=-3

-3/-3=1

y=1x+c

c= y-intercept and (0,2) is the y-intercept so

y=1x+2

Answer:

[tex]\frac{3}{4} =\frac{18}{24}[/tex] The ratios are the same .

Step-by-step explanation:

When  y ∝ x then,

[tex]y=k*x[/tex]

When y ∝ 1/x then

[tex]y=\frac{k}{x}[/tex]

while k is a constant.

Answer:

3/4 and 18/24; the ratios are the same.

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "three is to four as eighteen is to twenty-four."

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Here, 3 and 24 are the extremes, and 4 and 18 are the means. Since the cross products are both equal to 60, we know that these ratios are equal and that this is a true proportion.

x= -1/4, y= -7/8

Step-by-step explanation:

Answer:

x=-4, y=-6.5

Step-by-step explanation:

First, we need to find the value of x so

x+2=-2

-2 -2

x=-4

now plug the value of x, in the second equation

-3(-4)+2y=-1

12+2y=-1

minus 12 from both sides

12+2y=-1

-12 -12

2y=-13

divide by 2 to get the value of y

y=-6.5

The cost of 0.8 pounds of cheddar cheese is $4.28.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Jasper buys 0.8 pounds of cheddar cheese.

The cheese costs $5.35 per pound

So, cost of 0.8 pounds of cheddar cheese is

0.8×5.35

= $4.28

Therefore, the cost of 0.8 pounds of cheddar cheese is $4.28.

Answer:

8 feet.

Step-by-step explanation:

If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio

[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.
