(-5,-3), Parallel to -3x - 7y = 10, Put in slope-intercept form.
So, we must find the slope of this first.
-3x - 7y = 10
Add 3x to both sides.
-7y = 3x + 10
Divide both sides by -7.
y = -3/7x - 10/7
So, our slope is -3/7.
Remember, if you're looking for a line that is parallel to something, the slopes always stay the same.
*Also remember that slope-intercept form is y = mx+b*
Where m = slope, and b = y-intercept.
We have the points (-5,-3) so our y-intercept is -3.
Our slope is -3/7.
So, simply plug in those values into the slope-intercept form equation! :)
y = mx + b
y = -3/7x - 3

Answer:
C
Step-by-step explanation:
Go up the y axis and find the number six, look to the left and find where the x axis connects and then look to the right and do the same.
Your answer is 7 because when you divide two negative you get a positive answer
W=x
L=2x+17
Double everything since we need to lengths and two widths to find the perimeter
2x+17+2x+17+x+x = 76
Combine like terms
6x+34=76
Solve for x
First step is subtract 34 from both sides
6x=42
Next you divide both sides by 6 in order to get x by itself
X=7
Now you plug in 7 into the x’s in length and width
W=7 cm
L=31 cm
THE WIDTH IS 31 CM
Check:
7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.
Answer:x= 36 y= 67 and z=77
Step-by-step explanation: we have to write the equations from the data give in the exercise, this means :
First of all, x,y and z correspònd to the first, second and third angles, respectively.
The sum of the measures of the angles of a triangle is 180
can be written as x+y+z=180
The sum of the measures of the second and third angles is four times the measure of the first angle.
It can be written by: x+y=4z
The third angle is 10 more than the second
It can be written as z=y+10
By solving the equations systems the above values can be determined.
x+y+z=180
x+y=4z
z=y+10
