Answer:

$4.50

Step-by-step explanation:

First step is to find the price per orange. You can do this by dividing total cost by oranges bought. See below.

4 \div 8 \\  = .50

Now to find the amount of 9 oranges, you'd multiply price per orange by the specified amount needed (so 9)

9 \times .50 \\  = 4.50

Any one that knows this please help thanks!
Vesnalui [34]
If x = 4, you would replace the “x”s with 4’s! So the problem would work out to be 4^2 - 4 over 4 - 8. 4^2 = 16. You would then subtract. 16 - 4 = 12. Now your problem is 12 over 4 - 8. 4 - 8 = -4. Now your problem is 12 over -4. So now you just divide. 12 / -4 = -3! -3 should be your answer! If you need me to write it out to show you I’d be happy to! Hope this helps! :)

To calculate the area of a parallelogram, the formula is Area=base*height

In this case, the base is 14ft and the height is 12ft

so,

14ft*12ft=168ft^2

He needs 168ft or fabric to cover the area

when writing the equation of a line in slope-intercept form, how can you determine the value of m in y=mx+b if you know the coor
vovangra [49]

Answer:

y = -2.5 x + 6.5

Step-by-step explanation:

The equation of a line in slope-intercept form is written as

y = mx + b where m is the slope and b is the y-intercept.

a) We can find the slope of the line passing through (-1,30 and (-4, 5) by subtracting the y coordinates and dividing the difference by the difference if the x coordinates:

m = (5 - 3 )  = 2

     -4 - (-1)    -3

Now use this slope and substitute the coordinates of either of the given points to find the y-intercept, b . Let's use (-1,3):

y = mx + b

3 = -2 • -1 + b

3

3= 2 + b

3

7  = b

3

The equation of the line will be y = -2 x +  7

3 3

b) Using y = mx + b, we can substitute -2.5 for the slope and use the point to find the y-intercept:

y = -2.5x + b

1.5 = -2.5 • 2 + b

1.5 = -5 + b

6.5 = b

The equation of the line will be:

y = -2.5 x + 6.5
