So to solve this question, your goal is to find out how the way it is solved is not correct.

Your answer would be: On the third line, the student adds the 8 to both sides instead of subtracting. The way the initial equation is given is

y-(-8)=-6(x-2). After distributing the six, the student should make the 8 positive because subtracting a negative makes a positive. After solving, the equation should look like: y(+8)=-6x+12, so you would subtract the 8 from both sides instead of adding it, and solve from there.

McKenzie runs 1.5 mi every 10 min. At this rate, how many miles does she run in 1 hour? Enter your answer in the box.

prohojiy [21]

There are 60 minutes in an hour. 6x10=60. if 6*10=50, and there are 1.5 mi per every 10 minutes, we multiply 1.5 times 6 to get our answer, which is 9.

our answer is 9, i think

How would you graph this y-3=4/3(x+2)

VikaD [51]

Answer:

The line passes through $(-\frac{17}{4},0)\ and\ (0,\frac{17}{3})$ .

Graph is attached.

Step-by-step explanation:

Line passing through the point $(x_1,y_1)$ and slope $m$ :

$y-y_1=m(x-x_1)$

$Compare\ y-3=\frac{4}{3}(x+2)\ with\ the\ standard\ form\\\\x_1=-2,\ y_1=3\ and\ m=\frac{4}{3}\\\\This\ is\ equation\ of\ line\ passing\ through\ (-2,3)\ and\ having\ slope(m)=\frac{4}{3}\\\\Slope=\tan \theta\\\\\tan\theta=\frac{4}{3}\\\\\theta=\tan^{-1} \frac{4}{3}\\\\\theta=53.13\textdegree\\\\Hence\ line\ passes\ through\ (-2,3)\ and\ makes\ an\ angle\ 53.13\textdegree\ with\ the\ x-axis$

Sketch:

Y-intercept:

$substitute\ x=0\\\\y-3=\frac{4}{3}\times 2\\\\y=\frac{8}{3}+3\\\\y=\frac{17}{3}\\\\line\ passes\ through\ (0,\frac{17}{3}).$

x-intercept:

$substitute\ y=0\\\\-3=\frac{4}{3}(x+2)\\\\x+2=-\frac{3}{4}\times 3\\\\x=-\frac{9}{4}-2\\\\x=-\frac{17}{4}\\\\Line\ passes\ through\ (-\frac{17}{4},0).$

Sketch the line passes through $(-\frac{17}{4},0)\ and\ (0,\frac{17}{3})$ .

Find the percent. Round to the nearest whole percent. 159 people in favor out of 350 people surveyed.

hodyreva [135]

45% all you have to do is divide 159/350 and then take the decimal put over two spaces and round the third number, 5 or more raise it, 4 or less leave it

Find the sum: (n + 7) + (n - 14)

Vika [28.1K]

Answer:

Step-by-step explanation:

To get the sum you would combine like terms.

So:

n + n= 2n

7 + -14 = 7 - 14 = -7

Put it together:

2n - 7

Sphinxa [80]

Answer:

3. Walter's sample is not representative. 4. The population is his community service group.

Step-by-step explanation:

3. His sample is not representative because the survey was only on his math class, not the whole entire population. This sample only represents his math class.

4. The population is his community service group that is what class he is surveying 15 members from.

Hope this helped!
