Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1
Answer: 24 
Step-by-step explanation:
A=1/2hb
to find lenth of triangle: the side of the square is 10 and on the top, the triangle takes up 10-6 in so it must be 4 in long
to find height, it is 16-10 in of of the square. so itmust be 6 in
so to find area:
A=1/2*6*4
= 1/2*24
=24
Answer:
On a coordinate plane, a dashed straight line with negative slope goes through (negative -5/3, 0) and (0, negative 5). Everything to the right of the line is shaded
Step-by-step explanation:
6x + 2y > –10
Solve for y
Subtract 6x from each side
2y > -6x -10
Divide by 2
y > -3x - 5
The y intercept is -5 and the slope is -3
The x intercept is -5/3
The line is dashed and shaded to the right
Total distance traveled by Fernando's family = 272 miles
Time taken to travel the distance of 272 miles = 4 hours
Then we can say that
The distance traveled by Fernando's family in 4 hours = 272 miles
So
The distance traveled by
Fernando's family in 1 hour = (272/4) * 1 miles
= 68 miles
From the above deduction we can easily conclude that Fernando's family traveled at a rate of 68 miles per hour. I hope to have helped you.
Step-by-step explanation:
I don't know the area of the glass front of your largest building.
but just think :
1 gallon of fluid costs $12
1 gallon cleans 5000 ft²
so, now, find the area (ft²) of that glass front and see what number you have to multiply 5000 with to get the area of the glass front.
then, you have to multiply $12 with that same number, and you get the price.
let's say the building's glass front has 10000 ft².
what do I have to multiply with 5000 to get 10000 ?
this is the same question as how often fits 5000 into 10000 ? which is 10000 / 5000 = 2
and 12×2 = $24 as total cost to clean it.
our the building's glad front has 2500 ft².
what do I have to multiply with 5000 to get 2500 ?
this is the same question as how often fits 5000 into 2500 ? which is 2500 / 5000 = 1/2
and 12 × 1/2 = $6 as total cost to clean it.
