Answer:
16.75%
Step-by-step explanation:
find the difference:
23000 - 19700 = 3300
no divide 3300 by 19700 to get the percent
3300 / 19700 = 0.1675
move decimal twice for percent
16.75%
Answer:
To find the x -intercept, set y=0 .
Therefore, the x -intercept is (−4,0) . To find the y -intercept, set x=0 .
−3x+2y↓−3(0)+2y2yy=12=12=12=6Tofindthey−intercept,setx=0.
Step-by-step explanation:
To find the x - and y -intercepts algebraically, use the fact that all x -intercepts have a y -value of zero and all y -intercepts have an x -value of zero. To find the y -intercept, set x=0 and determine the corresponding y -value. Similarly, to find the x -intercept, set y=0 and determine the corresponding x -value.
John spent 2.4 hours working on the project.
Step-by-step explanation:
Let,
Number of hours worked by Dawn = x
Number of hours worked by Keith = y
Number of hours worked by John = z
According to given statement;
Dawn spent 1.2 hours less than 6 times as many hours on the project as John did.
x = 6z-1.2 Eqn 1
y = 5z+1.2 Eqn 2
As Dawn and Keith worked same amount, therefore,
Eqn 1 = Eqn 2
![6z-1.2=5z+1.2\\6z-5z=1.2+1.2\\z=2.4](https://tex.z-dn.net/?f=6z-1.2%3D5z%2B1.2%5C%5C6z-5z%3D1.2%2B1.2%5C%5Cz%3D2.4)
John spent 2.4 hours working on the project.

Learn how to find the slope below for the other problems.
Step-by-step explanation:
Slope is the rate of change for a linear function. It is found by subtracting the y values of two point on the line and dividing that difference by the difference of the x values of the points.
It can also be found using the formula y=mx+b known as the slope intercept form.
Here are a few examples:
0. This is a horizontal line which always has slope 0.
1. This is a vertical line which always has slope undefined.
2. Find two points that cross through a grid line intersection The line appears to cross them at (5,3) and (0,6). Count the unit squares between the two by counting up 3 and over to the left 5. Because it is left it is negative. The slope is -3/5
3. To find the slope, use the slope formula:
Since we can't divide by 0, it is undefined.
7. y=493x-257 follows the formula y=mx+b where m is the slope. m=493. The slope is 493.
8. Covert the equation into y=mx+b by rearranging the terms using y=mx+b.
5x-2y=48
-2y=48-5x
y=5/2 x -24
So the slope is 5/2.
