10x-6y=-48
standard to slope intercept form
Answers
Answer:
[tex]y=\frac{5}{3}x+8[/tex]
Step-by-step explanation:
Remember, slope intercept form is:
y = mx + b
where m is the slope and b is the y-intercept.
To get the given equation into slope-intercept form, we would have to first solve for y in terms of x.
10x - 6y = -48
Subtract 10x from both sides.
-6y = -48 - 10x
Multiply both sides by -1.
6y = 10x + 48
Divide both sides by 6.
[tex]y=\frac{5}{3}x+8[/tex]
And now, looking at the equation that we found and the equation for slope-intercept form, we can see that we have found the equation for 10x - 6y = -48 in slope-intercept form.

At a local pumpkin patch you can pick your own pumpkins. There is a $5 charge to enter the patch and then a $0.25 charge per pound of pumpkin. Let p
represent the weight of the pumpkin you choose and C(p)
represent the total cost of the pumpkin in terms of the weight of the pumpkin. Equation, in function notation:
Answers
Answer:
C(p) = 0.25p + 5
Step-by-step explanation:
$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.
m = slope, b = y-intercept
C(p) = mp + b
C(p) = 0.25p + 5
Question 3 What is the slope of the line that passes through the points (0.-7) and (-4, 3)? 0 -3/11 O -2/5 À O -5/2 0 10/4 Question 4
Answers
Answer:
Gradient = Change in y / Change in x
Gradient = (-7-3) / (0-4)
Gradient = -10/-4
Gradient = 2.5
So the answer is 10/4, which is 2.5
The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.
Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 3 - (-7) / ( -4 - 0 )
Slope = 10 / -4
Slope = -5 / 2

Step-by-step explanation:
In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.
Answer:
B. 8.0

To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8

I think it's 1800 Degress
Step-by-step explanation:
If the CD rotates 300 times per minute, we know that equals 300 rotations/60 seconds
That ends up being 5 rotations per second.
Since we know that a full rotation is 360 degrees, then it should equal 1800 degrees.

Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals negative 3 over 6 units
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals 3 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals 5 over 6 units

Yesterday, Kate gave exactly fourteen haircuts
and made $50.00. If she charged $5.00 for adults'
haircuts and $2.50 for children's haircuts, how
many children's haircuts did she give?
A) 5
B) 6
C) 7
D) 8
Answers
Answer:
D) 8
Step-by-step explanation:
8 x 2.5 = 20
and the rest is adult haircuts
6 x 5 = 30
Answer:
D) 8 Children’s Haircuts
Step-by-step explanation:
Let a represent the amount of adult haircuts and c represent the amount of child haircuts.
We know that she gave exactly 14 haircuts. So:
[tex]a+c=14[/tex]
We also know that she made $50.00. Therefore, the price of each haircut times their respective amounts will total $50. So:
[tex]5a+2.5c=50[/tex]
This is now a system of equations.
We can solve this using substitution. From the first equation, let’s subtract c from both sides:
[tex]a=14-c[/tex]
Now, we can substitute this into the second equation for a. This yields:
[tex]5(14-c)+2.5c=50[/tex]
Distribute:
[tex]70-5c+2.5c=50[/tex]
Combine Like Terms:
[tex]70-2.5c=50[/tex]
Subtract 70 from both sides:
[tex]-2.5c=-20[/tex]
Divide both sides by -2.5:
[tex]c=8[/tex]
Therefore, Kate gave 8 children’s haircuts.
This means that she gave [tex]14-8=6[/tex] adult haircuts.
So, our answer is D. She gave 8 children’s haircuts.
