Answer:
x intercept (-45,0)
Step-by-step explanation:
to find the x-intercept substitute in 0 for y and solve for x
1/3x+0=-15
1/3x=-15
1/3 ÷ 1/3 = -15 ÷ 1/3
x = -45

Two trains leave stations 468 kilometers apart at the same time and travel toward each other. One train travels at 85 kilometers per hour while the other travels at 95 kilometers per hour. How long will it take for the two trains to meet?
Do not do any rounding.
Answer:
It should be 2 hrs 36 minutes
Step-by-step explanation:
Closing speed:: 85 + 95 mph = 180 mph
Ans:: time = distance/rate = 468/180 = 2.6 hrs = 2 hrs 36 minutes

Answer:
A) -7/16÷3= -7/48 This will tell you how much the water level changed in 1 year.
B) -7/48(7)= -1 1/48 This tells you how much the water level changed over a 7 year period
C) It is a terminating decimal because -1 1/48 as a decimal is −1.0208333333333
Richard had his car repaired at a body shop.
The parts cost $100.
The technician charged $52 per hour.
His total bill was $308.
How many hours did the technician work on Richard's car?
Answer:
4 hours
Step-by-step explanation:
total bill is 308
take the price of the car part away 308-100=208
this gives the total amount for the no. of hours worked
208/52=4

Answer:
(12^2)+(4^2)=160
[tex]\sqrt{160}[/tex]=Large side of a rectangle
(2^2)+(6^2)=40
[tex]\sqrt{40}[/tex]=small side of a rectangle
[tex]\sqrt{160} *\sqrt{40} =\sqrt{160*40} =80[/tex] area
Step-by-step explanation: 12*4=48/2=24Large triangle area
2*6=12/2=6 small triangle area
Two large triangles=2*24=48
two small triangle=2*6=12
48+12=60
Largerectangle area=14*10=140
140-60=80
Answer: The area of the shaded rectangle is 80 square units.
Step-by-step explanation: Break down the shapes. Add up the areas of the triangles around the sides and subtract from the larger rectangle.
The small triangles areas are A=6*2÷2, 12÷2=6 square units each.
The larger triangles have areas of 4 ×12 ÷2, so 24 square units each.
Add those areas: 6+6+24+24=60
Next, Figure out the area of the larger rectangle. Add the numbers on the sides. The length is 2+12=14. The width is 6+4=10
Multiply to get the area 14×10=140 square units.
Subtract the area of the triangles from the area of the larger rectangle to get the area of the shaded rectangle: 140-60=80 square units.

Answer:
Y = 3x is your best bet
y = 62x + 31 (y = 2x + 1, if it is scaled by a factor of 31 for y(miles), and 1 for x(time in hours)).
Step-by-step explanation:
This equation is in the form of slope intercept: y = mx + b. Where m is the slope(rise over run/change in y over change in x), and b is the y intercept(where x is 0, and intersects the y axis)
the y intercept is 31 because this is where the line intersects the y axis, and where x is zero.
the slope is 62 since 93-31/1-0 = 62/1 = 62. or if scaled 3-1/1-0 = 2/1 = 2, and 1 for the y intercept if scaled.
Make a table of ordered pairs for the equation.
y=−13x+4
can someone please help! im a 7th grader that just got moved into all 8th grade classes and now im really struggling.. can someone please explain how to find ordered pairs for equations ? thanks!
Answer:
Just plug In values for x and find the output.
Step-by-step explanation:
If x is 1 then y is -1/3(1)+4, which is 11/3. (1, 11/3)
If x is 2 then y is -1/3(2)+4, which is 10/3. (2,10/3)
And so on...
Answer:
wow, congrats on moving up a math grade. sorry to hear you're struggling, hope I can help!
so the rule would be y = [tex]\frac{1}{3}[/tex]x + 4.
to start, say x = 2.
put that into the equation
y = (1/3*2) + 4
y = 2/3 + 4
y = [tex]4\frac{2}{3}[/tex] or 4.66
so if x = 2, y = [tex]4\frac{2}{3}[/tex]
try this again when x = 3.
put that into the equation:
y = (1/3 * 3) + 4
y = 1 + 4
y = 5
so if x = 3, y = 5
I can't put tables into brainly easily, but I hope this helps! goodluck!

A rectangular driveway is 23.5 feet long and 9.25 feet wide. What is the area of the driveway in square feet?
Answer:
A: 217.375 ft^2
Step-by-step explanation:
Lengths: a: 23.5 b: 9.25
Perimeter: u: 65.5
diagonal : d: 25.255
Area: A: 217.375
Calculate area A: Use the formula A=a*b
A=a*b
Insertion into A=1*a*b gives
A=1*23.5*9.25

Answer:
(-2, -6 2/3), (-1, -6 1/3), (0,-6), (1,-5 2/3), (2, -5 1/3)
Step-by-step explanation:
For the values let's use -2,-1,0,1, and 2
The equation we need to use is slope-intercept (y=1/3x-6)
y=1/3(-2)-6
y=-2/3-6
y=-6 2/3
So the point for this one is (-2,-6 2/3)
Next, we'll plug in -1
y=1/3(-1)-6
y=-1/3-6
y=-6 1/3
The point for this one is (-1, -6 1/3)
Now we plugin 0
y=1/3(0)-6
y=0-6
y=-6
the point for this one is (0,-6)
Now we put in 1
y=1/3(1)-6
y=1/3-6
y=-5 2/3
the point is (1, -5 2/3)
Lastly, we plugin 2
y=1/3(2)-6
y=2/3-6
y=-5 1/3
The last point is (2, -5 1/3)
Hope you get a good grade!
