Answer:
Equation of the straight line in point-slope form
y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)
Equation of the straight line
3x +4y +4=0
Step-by-step explanation:
Explanation:-
Given that the point ( 8,-7) and [tex]m = \frac{-3}{4}[/tex]
Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'
y - y₁ = m (x-x₁)
y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)
4( y+7) = -3(x-8)
4y +28 = -3x +24
3x +4y +28 -24 =0
3x +4y +4=0
Is either x = 18 or x = 14 a solution to x – 8 < 9? A. They are both solutions B. x = 18 is a solution, but x = 14 is not ОО O C. Neither is a solution D. X= 14 is a solution, but X-18 is not
Answer:
Answer is D
Step-by-step explanation:
u have two given values of x
x=18 and x=14
put them in the given equation x-8<9
1.FIRST put x = 18
that is (18)-8<9
10<9--->THIS IS INCORRECT BECAUSE 10 IS MORE THAN 9
2.SECOND put x = 14
that is (14)-8<9
6<9---->THIS IS CORRECT SINCE 6 IS LESS THAN 9.

All i infer is that first, it is called climate change, and second, climate change has nothing to do with math, and third, climate change is mostly from human pollution.
Step-by-step explanation:
Cost of a lizard: $36.50
Markup: 70%
Discount: 53%
Can anyone answer this with work or a detailed explanation? I think I’ve got the answer but I want to be sure.
Answer:
Cost after markup = $62.05
Cost after discount = $29.18
Step-by-step explanation:
It is given that:
Cost of lizard = $36.50
Mark up = 70% = 70/100 = 0.7
Markup = 0.7 * 36.50
Markup = $25.55
Cost after markup = 36.50 + 25.55 = $62.05
Discount = 53%
Discount = 0.53 * 62.05
Discount = $32.87
Price after discount = 62.05 - 32.87 = $29.18
Therefore,
Cost after markup = $62.05
Cost after discount = $29.18

Answer:
Rectangle Y.
Step-by-step explanation:
Find the perimeter of both rectangles.
If you want to find rectangle X, the breadth of the rectangle but the length of it isn't the same since it has been shortened, and since it covers half of the card for length...
Length = 14 ÷ 2 = 7cm
Perimeter = 6cm + 6cm + 7cm + 7cm = 26cm (Rectangle X)
Now, let's find perimeter for rectangle Y.
The length for the rectangle is the same as it isn't shortened or anything else, but the breadth is different as it have been shortened, since it covers half of the card for breadth...
Breadth = 6 ÷ 2 = 3cm
Perimeter = 3cm + 3cm + 14cm + 14cm = 34cm
(Rectangle Y)
Explaination: Rectangle Y will have the longer perimeter, (add in the solution that I wrote for rectangle X and Y)
The ratio of boys to girls in a group is 7:3. If there are 40 more boys than girls, work out how many girls there are
Answer:
Odadasdsadasadad
Step-by-step explanation:
Answer:
These units equal to 40. Therefore, each of these units would be equal to 10. If this is the case, then for the ratio to be true, each of the other units would be 10 as well. Therefore, this will give a total of 100.

Your doctor told you to eat 25 25 grams of fiber each day. You had 4 4 grams of fiber for breakfast. What percent of the 25 25 grams of fiber have you eaten so far?
Answer: 16%
Step-by-step explanation:
Grams of fiber recommended by doctor = 25 grams
Grams of fiber had for breakfast = 4
Percentage of gram ate = Grams had for breakfast / Grams recommended by doctor × 100
= 4/25 × 100
= 4 × 4
= 16%
Answer: 16%

Explanation:
ick to add speaker notes
Step-by-step explanation:
Subtract initial amount (300) and final (150). from there you get 150 dollars that was lost. We know that every step you 5 dollars so then divide 150 and 5 to get 30. So the distance was 30 steps.

Angelica has a babysitting business. She babysat on Friday night and made $60
plus a 20% tip. How much was the tip? How much was the total?
Answer:
The tip was $12. The total was $72.
Step-by-step explanation:
First, we need to find how much the tip is. 20%=1/5 of the amount of money. If you divide 60 by 5, you get 12. This means that the tip was 12 dollars. If you add 60+12 you get 72 meaning that the total amount of money Angelica got was $72.
What is the length of AD?
Answer:
So, We Need To Write An Equation To Find This:
AD = lAl + lDl Step-by-step explanation:
AD = l-7l + l8l
l-7l= 7.
AD = 7 + 8
7+8 = 15
AD = 15 So, AD = 15. This Means That The Answer Is B.
A movie theater charges \$10.50$10.50dollar sign, 10, point, 50 per ticket and \$5$5dollar sign, 5 per bucket of popcorn. You never buy the popcorn because you think it's too expensive.
Is the total price you pay proportional to the number of tickets you buy?
Answer:
yes
Step-by-step explanation:
Let's make a table to see the total price for different numbers of tickets.
Number of tickets 111 222 333
Total price \$10.50$10.50dollar sign, 10, point, 50 \$21$21dollar sign, 21 \$31.50$31.50dollar sign, 31, point, 50
Hint #22 / 4
For each number of tickets bought, let's write the relationship of total price to number of tickets as a ratio in simplest form.
\dfrac{\$10.50}{1} = \$10.50 ~~~~~~~~~\dfrac{\$21}{2} = \$10.50 ~~~~~~~~~\dfrac{\$31.50}{3} = \$10.50

Answer:
Answer will 19/4 hope it helps
Answer:1,1/2
Step-by-step explanation: First, we got to make an common denomanator, which is 24. 2 1/4 would be 2 6/24, and 3/6 would be 12/24. then, we use 2,6/24 and subtract it by 12/24, which is 1, 18/24, simplified to 1,1/2
