Which is the equation of the given line? (-10,-7) (3,-7)

Vladimir [108]

Answer: $y=-7$

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

$m=\frac{-7-(-7)}{-10-3}\\\\m=\frac{0}{-13}\\\\m=0$

Substitute the slope and any point into $y=mx+b$ and solve for "b":

$-7=0x+b\\b=-7$

Then, substituting "m" and "b" into the equation $y=mx+b$ , you get that the equation of this line is:

$y=0x-7$

$y=-7$

The perimeter of a rectangle is 202. The length is 26 more than 4 times the width. Find the dimensions

jek_recluse [69]

Answer:

$P = 2*(26+4y) + 4y$

And if we solve for y we got:

$202= 52 +8y +4y$

$202= 52 +12 y$

And replacing we got:

$150 = 12y$

And we got:

$y = \frac{150}{12}= 12.5$

And for x we got:

$x = 26 +4*12.5 = 76$

So then the length would be 76 and the width we got 12.5

Step-by-step explanation:

For this case we have a rectangle. The perimeter is given by:

$P= 2x+2y$

Where x represent the length and y the the width. We can set the following conditions:

$x = 26 +4y$

And if we replace the conditions we got:

$P = 2*(26+4y) + 4y$

And if we solve for y we got:

$202= 52 +8y +4y$

$202= 52 +12 y$

And replacing we got:

$150 = 12y$

And we got:

$y = \frac{150}{12}= 12.5$

And for x we got:

$x = 26 +4*12.5 = 76$

So then the length would be 76 and the width we got 12.5

HELP PLEASE BEST ANSWER WILL BE MARK AS BRAINLIEST!

Gwar [14]

First of all,
The total weight of the six dogs are:
71+34+15+23+18+56=217 pounds
Then, we know that the average weight of the seven dogs are 40 pounds, so the total weights of the seven dogs are:
40×7=280 pounds.
Lastly, we know that the six dogs weights are 217 pounds and the total weight of the seven dogs are 280 dogs, so the seventh weight of the dog is:
280-217=63 pounds. As a result, the seventh weight of the dogs at the vet is 63 pounds. Hope it help!
