Step-by-step explanation:
the equation is y=mx + b. the m (or the thing that comes before the x in the equation) is your slope, the y intercept is the last number. if the last number is preceded by a minus sign, the intercept number is negative
Answer:
For example, number 1's slope is 5/3. On a graph, you would go up 5 (not in block, but in numerical value) and right 3. The y-intercept is -2. This is where your line starts on the graph.
Step-by-step explanation:
y=mx+b b= y-intercept y-intercept=where the line crosses the y-axis m=slope slope== rise/run or slope formula, m=y2-y1/x2-x1

Answers
Answer:
y + 7 = (-14/17)(x - 8)
Step-by-step explanation:
We want the equation of this line in the point-slope form y - k = m(x - h).
We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:
Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:
7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17
The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).
Another way to get this result would be to find m in the usual way:
rise 14
m = ------------- = --------- = -14/17 (same as before).
run -17

Find the product of 51 and -2.5.
Use the distributive property to rewrite and solve.
The first step is done for you.
51(-2.0) + 51(-0.5)
What is the next step in using the distributive property to solve this equation?
A) -102 + 25.5
B) 102 + (-25.5)
C) -102 + (-25.5)
D) -102 + (-25)
Answers
Answer:
A. -102 + 25.5.
Step-by-step explanation:
After multiplying 51 by -2.0, you will get -102. When multiplying 51 by -0.5, you get 25.5. A is the next step in this equation. (Optional answer: read this when this is also in your quiz. -102 + 25.5 = 127.5).

help me it's algebra and dont tell me to look at the lesson :)
Answers
Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.
He's supposed to use a total of between 70 and 74 beads, so
70 ≤ b + g ≤ 74
The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so
1.4 ≤ g/b ≤ 1.6
For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions
b ≥ 0
g ≥ 0
(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)

Answers
Answer:
40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:
40
Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.
Then you will get 40 degrees as your answer.

Step-by-step explanation:
a store sells laptops for 720 each. this price is 20 percent more than what it cost the store to buy each of them. before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost cost. how much would it cost an employee to purchase one of these laptops at the sale?
Answers
Answer:
462
Step-by-step explanation:
720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.
720*5/6= 600
The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.
600*0.77 = 462
The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.
Given :
A store sells laptops for 720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:
Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.
Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:
[tex]=\dfrac{720}{120}\times 100[/tex]
= 600
Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.
Step 4 - So, the total cost of the laptop at which an employee purchase is:
[tex]=\dfrac{77}{100}\times 600[/tex]
= 462

$145.80
Step-by-step explanation:
The original cost of the product was $90. There was a 162% markup. In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%). After taking away 100%, I am left with 62%. I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8. Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.

Answers
Answer:
Given : Michael and Imani go out to eat for lunch.
their food and beverages cost $25.30
8% meals tax,
After adding a tip, the total lunch cost was $32.24
To Find : how much is the bill
What percentage tip did they give?
Solution:
food and beverages cost $25.30
8% meals tax,
Tax = (8/100) 25.3 = 2.02 $
BILL = 25.30 + 2.02
= 27.32 $
BILL = 27.32 $
After adding a tip, the total lunch cost was $32.24.
=> Tip = 32.24. - 27.32 = 4.92$
% of Tip = (4.92 / 27.32) * 100 = 18 %
Tip = 18 %
Step-by-step explanation:
Answer:
Part A: $28.46
Part B: 8.5%
Step-by-step explanation:
Part A:
We know that in this equation that 25.30 is the 100% number and we need to find 8% of this.
We can then divide 8 by 25.30 which is 3.1625 but the problem asks us to "round to the nearest cent" so we then know that the 8% is $3.16 we have to then add the 8% to the total which would be: 25.30 + 3.16 which equals $28.46 which is your answer to Part A.
Part B:
After adding a tip that problem states that the total went up from $28.46 to $32.24 to find out how much they tipped we can minus these 2 totals to find the difference
32.24 - 28.46 = 3.78
We now know that they tipped $3.78 and we now need to convert this into a percentage.
Right now the whole 100% is $32.24, we then divided 32.24 by 3.78 which would be 8.5291 and so on but wo round this it would be 8.5%
The answer to Part B would be 8.5%

Step-by-step explanation:
Hey there!
1,000 - 100 + 10 - 1
1,000 - 100 = 900
= 900 + 10 - 1
900 + 10 = 910
= 910 - 1

Thus that’s why 1,000 - 100 + 10 - 1 is most likely equal to 909
