Answer:
y=-5x-13
Step-by-step explanation:
use y-y1=m(x-x1)
y+8=-5(x+1)
y+8=-5x-5
subtract 8 from both sides
y=-5x-13

Among the 7th graders in a middle school, three quarters of them play at least one sport. Among the 7th graders who play sports, half of them play more than one sport. Among the 7th graders who play more than one sport, one third of them play more than two sports. Among the 7th graders who play more than two sports, one quarter of them play more than three sports. Sixteen 7th graders play more than three sports at the school. How many 7th graders are in the school
Answer:
512
Step-by-step explanation:
Let the number of 7th graders in the school is x.
As three-quarters of them play at least one sport, so, the number of 7th graders who play sport = [tex]\frac 3 4 x[/tex].
Among the 7th graders who play sports, half of them play more than one sport. So, the number of 7th graders who play more than one sport [tex]= \frac 1 2\times \frac 3 4 x=\frac 3 8 x[/tex].
Among the 7th graders who play more than one sport, one-third of them play more than two sports. So, the number of 7th graders who play more than two sport [tex]= \frac 1 3\times \frac 3 8 x=\frac 1 8 x[/tex].
Among the 7th graders who play more than two sports, one-quarter of them play more than three sports.
So, the number of 7th graders who play more than three sport [tex]= \frac 1 4\times \frac 1 8 x=\frac{1}{32} x[/tex].
7th graders play more than three sports at the school= 16
[tex]\Rightarrow \frac{1}{32} x=16[/tex]
[tex]\Rightarrow x =16 \times 32[/tex]
[tex]\Rightarrow x = 512[/tex]
Hence, the total numbers of 7th graders in the school are 512.
solve for x: -2(x+9)=5(x-7)
Answer: [tex]x[/tex] = [tex]\frac{17}{7}[/tex]
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
Step 1: Expand.
−2[tex]x[/tex] − 18 = 5[tex]x[/tex] − 35
Step 2: Add 2[tex]x[/tex] to both sides.
−18 = 5x − 35 + 2[tex]x[/tex]
Step 3: Simplify 5[tex]x[/tex] − 35 + 2[tex]x[/tex] to 7[tex]x[/tex] − 35.
−18 = 7[tex]x[/tex] − 35
Step 4: Add 35 to both sides.
−18 + 35 = 7[tex]x[/tex]
Step 5: Simplify −18 + 35 to 17.
17 = 7[tex]x[/tex]
Step 6: Divide both sides by 7.
[tex]\frac{17}{7}[/tex] = [tex]x[/tex]
Step 7: Switch sides.
[tex]x[/tex] = [tex]\frac{17}{7}[/tex]

I need help! The 20% off sale is a better deal than the $200 rebate or $150 coupon for the $1,500 dining room set. Explain why this is the best deal for them. Are they under budget?
Answer:
See explanation
Step-by-step explanation:
The 20% off sale is a better deal because 20% off of $1500 will cost $1200. (See work).
However, the 200 or 150 dollars off will cost $1300-1350. Thus, the better deal for the dining room set is to use the 20% off.
If their budget is $1250, they will be $50 under budget because they would be paying $1200 for the set.
Work:
1500 x 20%
1500 x 0.20 = 300
1500-300= $1200
1500-150= 1350
1500-200= 1300
Yes, the Porters are under budget. The 20% off sale is the best deal because $1,500 times 0.20 is $300. $300 is a bigger discount than the $150 coupon and $200 rebate. $300 off $1,500 is $1,200, which is less than the amount budgeted.

What is the increasing and decreasing intervals of this graph?
Answer:
A function is increasing on an interval if its slope is positive on that interval. That is, if you follow it to the right, it'll go up.
The graph increases at 3 and decreases at 1
A function is decreasing on an interval if its slope is negative on that interval. That is, if you follow it to the right, it'll go down.
Step-by-step explanation:
hope this helped
The function is increasing at (1, 0) and decreasing at (3, 0).
Given is a graph we need to determine what is the increasing and decreasing intervals of this graph,
If a function's slope is positive on an interval, the function is increasing on that interval. That is, it will go up if you follow it to the right.
The graph goes up at 3 and down at 1.
If a function's slope is negative on an interval, the function is declining on that interval. That is, it will descend if you follow it to the right.
Hence the function is increasing at (1, 0) and decreasing at (3, 0).
