Write an equation of the line that passes through the points ( 4, 2), (0, -6) *
9514 1404 393
Answer:
y = 2x -6
Step-by-step explanation:
One form you can use for this purpose is ...
(x2 -x1)(y -y1) = (y2 -y1)(x -x1)
Filling in the given point values, this is ...
(0 -4)(y -2) = (-6 -2)(x -4)
-4y +8 = -8x +32
Generally, we like the equation to have coefficients with no common factors. All of these coefficients can be divided by -4.
y -2 = 2x -8
This can be rearranged to any form you may like--or left as is.
y = 2x -6 . . . . . slope-intercept form
A pack of four bags of coffee cost $39.96. How much would 16 bags of coffee cost.
SHOW YOUR WORK
Answer:
$159.84
What we know - 4 bags cost $39.96
What we need to know - How much 16 bags cost
Step-by-step explanation:
We can solve this by simply knowing how many times 4 goes into 16. We can do this by writing the equation 16 ÷ 4 = 4. We now know that 4 goes into 16 4 times. By doing this we can now multiply $39.96 by 4 to get the cost of 16 bags which is $159.84.

Answer:
D. 181.7 miles
Step-by-step explanation:
If the odometer can read to the nearest 0.1 miles, then you don't want to use A because its not as precise. You don't want to use B because its rounded up to the nearest hundreds. You don't want to use C because we don't know whats in the hundredths place, if the odometer only reads to the nearest 0.1 miles then it could be 181.3, or 181.9, we don't know that. Your answer is D.

Round to the nearest power of 10
3 x10^8
4×10^7
4x10^8
4x10^9
Answer:
4 x 10⁸
Step-by-step explanation:
Well 4 x 10⁸ is 400, 000, 000 which is the closest to 395, 280, 204. For future reference, the number of powers the 10 is raised to is the number of zeros it will have.
A hair stylist knows that 87% of her customers get a haircut and 40% get their hair colored on a regular basis. Of the customers who get their hair cut, 24% also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?
0.10
0.21
0.35
0.40
Answer:
Okay so!
Step-by-step explanation:
for a cut that's .87 and for a color that is .24 so you multiply them together to get the probability for the color which is
.35 or C on edge
The probability that a randomly selected customer gets their hair cut and colored is .
What is probability?Probability is the chance of happening an incident or event. A probability is calculated by the ratio of the possible outcomes to total number of outcomes.
Given, the probability of he customer get a hair cut is = P(A) = 87% = 0.87.
The probability of he customer get their hair colored is = P(B) = 40% = 0.4.
Therefore, the probability of a randomly selected customer get hair cut and hair color is = P(A) × P(B) = 0.87 × 0.4 = 0.35
Therefore, 35% of the total customer get hair cut and color.

Use the figure to find the measure of angle 1. *
Answer: angle 1 = 110 degrees
This is because angle 1 and the red 110 degree angle are corresponding angles.
They correspond to one another due to the fact they are both in the southwest corner of each 4-corner angle configuration (which is the result of crossing two lines)
Corresponding angles are congruent only when we have parallel lines like this.
This morning, Mai's car had 15.25 gallons of fuel. Now, 1.9 gallons are left. How much fuel did Mai use?
Answer:
13.35
Step-by-step explanation:
Just subtract. 15.25-1.9 gives you the difference.
Mai used 13.35 gallons of fuel.
Unitary method is a process by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
To calculate the fuel Mai used, we can subtract the remaining fuel from the initial amount of fuel.
This can be done as follows:
Initial amount of fuel = 15.25 gallons
Remaining amount of fuel = 1.9 gallons
Fuel used = Initial amount of fuel - Remaining amount of fuel
Therefore, Fuel used = 15.25 - 1.9
Fuel used = 13.35
Therefore, We can conclude that Mai used 13.35 gallons of fuel.

Students plan to pay back half the debt now though fundraising, and the rest after the harvest. Write an equation to represent the debt they will repay through fundraising. Use a negative integer to show debt. Use "D" to represent the debt that will be repaid by through fundraising.
Answer:
D = [tex]\frac{-d}{-2}[/tex]
Step-by-step explanation:
The students in this question are trying to pay back only half of the current debt (d) with the fundraiser (D). Since debt is money that is owed it would therefore be represented as a negative but in this case the fundraiser needs to be positive since it is money gained. So since we have a negative we would need to divide by -2 in order for the total to be positive.
D = [tex]\frac{-d}{-2}[/tex]
Finally, we are left with this equation which shows the debt that will be repaid through the fundraiser
