Write an equation for the line in slope intercept form to parallel to -x + 3y =-2 that contains the point (12,7)
kvasek [131]

The parallel lines have the same slope.

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have

-x+3y=-2\qquad|\text{add x to both sides}\\\\3y=x-2\qquad|\text{divide both sides by 3}\\\\y=\dfrac{1}{3}x-\dfrac{2}{3}\to m=\dfrac{1}{3}

Therefore searched line equation is:

y=\dfrac{1}{3}x+b

The line passes through point (12, 7). Put the coordinates of the point into the equation of the line:

7=\dfrac{1}{3}(12)+b\\\\7=4+b\qquad|\text{subtract 4 from both sides}\\\\3=b\to b=3

Answer: y=\dfrac{1}{3}x+3

Answer:

the second one 9v+36

Step-by-step explanation:

because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.

During a carpet sale, a carpet company sold $6,792 worth of carpet. If they sold 849 square yards of carpet, what was the averag
Alika [10]

Answer:

The average price per square yard is $8.00

Step-by-step explanation:

From the question

849 yd² = $6,796

1 yd² = x

Cross Multiply

849 yd² × x = 1 yd² × $6,796

x = 1 yd² × $6,796/849yd²

x = $8.0047114252

Approximately = $8.00

Therefore, the average price per square yard is $8.00

butalik [34]

Answer:

2nd debate was 3 hours long.

Step-by-step explanation:

We have been given that during the mayoral election,two debates were held between the candidates. The first debate lasted 1 2/3 hours. The second one was 1 4/5 times as long as the first one.

Let us find the estimate of time spent on 2nd debate.

1 2/3 hours would be approximately 2 hours. 1 4/5 times would be equal to 2 times.

2*2=4

Therefore, the estimated time is less 4 hours.

To find the time spent on 2nd debate, we will multiply 1 2/3 by 1 4/5.

First of all, we will convert mixed fractions into improper fractions as:

1\frac{2}{3}=\frac{5}{3}

1\frac{4}{5}=\frac{9}{5}

Now, we will multiply both fractions as:

\frac{5}{3}\times \frac{9}{5}

\frac{1}{3}\times \frac{9}{1}

\frac{9}{3}\Rightarrow 3

Therefore, the 2nd debate was 3 hours long.
