NEED HELP! A line has a slope of 9/7 and a y-intercept of 1/3. Which of the following is an equation of the line?
A 27x - 21y = -7
B 27x + 21y = 1
C 9x + 7y = 3
D 7x - 9y = -3
Please show work so I could understand this!
Answer:
A
Step-by-step explanation:
Take a look at the slope-intercept form of the equation .
[tex]y=mx+c[/tex]
Slope of 9/7 and y-intercept of 1/3 means replace m which is slope and c is the y-intercept which becomes
[tex]y=\frac{9}{7}x+\frac{1}{3}[/tex]
now we take LCM of 7 and 3 which becomes
[tex]y=\frac{27x+7}{21}[/tex]
and then,
[tex]21y=27x+7[/tex]
so A is our Answer
if arrange the equation accordingly
[tex]27x-21y=-7[/tex]

During a snowstorm, Eva tracked the amount on the ground. When the storm being, there was no snow on the ground. Snow feel at a constant rate of 3 inches per hour until 6 inches had fallen. The storm then stopped for 5 hours and then started again at a constant rate of 2 inches per hour for the next 2 hours. As soon as the storm stopped again the sun came out and melted the snow for the next 2 hours at a constant rate of 4 inches per hours
Answer:
2 inches of snow was left on the ground
Step-by-step explanation:
To calculate the amount of snow on the ground we can take it one step at a time. Since there was no snow on the ground we can start at a level of 0. Then it snowed until 6 inches of snow had fallen, so we can add that to our total.
0 + 6 = 6 inches
Next, it snowed for 2 more hours at a rate of 2 inches per hour, meaning we multiply this by 2 hours and add to the total amount of snow that was already on the ground.
(2*2) + 6 = 10 inches
Lastly, the sun came out and melted the snow on the ground for 2 hours at a rate of 4 inches per hour. Since it is melting the snow, this means that it is subtracting the snow from the total. So we would have to multiply the rate (4 inches per hour) by the number of hours and then subtract that from the amount of snow on the ground.
10 - (4*2) = 2 inches

For the equation 4(2x-3)-(mx+5)=5x+b to be an identity, which of the following must be true about the constants m and b? Show your work
(1) m = 3 and b = -7
(2) m = 8 and b = 17
(3) m = -3 and b = -15
(4) m = 3 and b = 17
Given:
The equation is
[tex]4(2x-3)-(mx+5)=5x+b[/tex]
To find:
The values of m and b.
Solution:
We have,
[tex]4(2x-3)-(mx+5)=5x+b[/tex]
Using distributive property, we get
[tex]8x-12-mx-5=5x+b[/tex]
On combining like terms, we get
[tex](8-m)x+(-12-5)=5x+b[/tex]
[tex](8-m)x-17=5x+b[/tex]
On comparing both sides, we get
[tex](8-m)=5[/tex]
[tex]-m=5-8[/tex]
[tex]-m=-3[/tex]
[tex]m=3[/tex]
And,
[tex]b=-17[/tex]
Therefore, m = 3 and b = 17.

Line ST and point V are shown on the graph. Line WW is to be drawn on the graph such that it is perpendicular to line ST. If the coordinates of point Ware (-1, y), what is the value of y?
-5
2
3
-7
Answer:
3
Step-by-step explanation:
We can use the formula of slope to find this answer.
The formula to find the slope is y2-y1/x2-x1.
The slope of line ST is 1/5: 2-0/5-(-5); 2/10=1/5
We know that for two lines to be perpendicular, they have to have reciprocal opposite slopes. For example, if the slope of a line is 2/1 then the slope of a line perpendicular is -1/2.
Therefore, the perpendicular line should have a slope of: 1/5------>-5
To find which answer it is, follow the steps below:
y2-y1/x2-x1
plugin known values
-2-y1/0-(-1)
-2-y1/1
In order to make this -5, y1 needs to be 3
-2-3/1=-5
3 is the correct value
The value of y is 3.
What is slope?The slope of a line is a measure of its steepness.
Given:
Ware( -1, y)
Now,
slope of line ST =2-0/5-(-5)
slope=1/5
As two lines to be perpendicular, they have to have reciprocal opposite slopes.
Thus, the perpendicular line slope =-5
Now, y2-y1/x2-x1
= -2-y1/0-(-1)
= -2-y1/1
= -2-3/1
=-5
hence, the value of y is 3.

Which ordered pair is the solution to the system of linear equations Negative 5 x + y = 26 and 2 x minus 7 y = 16?
9514 1404 393
Answer:
(-6, -4)
Step-by-step explanation:
If you're going to use technology to answer your questions, you may as well use appropriate technology: a graphing calculator. It shows the solution to the system is the ordered pair (-6, -4).
__
The first of the given equations can be solved for y, then that used to substitute for y in the second equation.
y = 5x +26
2x -7(5x +26) = 16
2x -35x -182 = 16
-198 = 33x . . . . . . . . add 33x-16
-6 = x . . . . . . . . . . . . divide by 33
y = 5(-6) +26 = -4 . . . find y
The solution is (x, y) = (-6, -4).
