Answer:
h = -2.5
Step-by-step explanation:
Apply the distributed property: -6h + 8h + 6 = 1Combine like terms: 2h + 6 = 1Subtract 6 from each side, so it now looks like this: 2h = -5Divide each side by 2 to cancel out the 2 next to h. It should now look like this: h = -2.5I hope this helps!
Answer:
h = -2.5
Step-by-step explanation:
-6h + 2(4h + 3) = 1
-6h + 2*4h + 2*3 = 1
-6h + 8h + 6 = 1 {combine like terms}
2h + 6 = 1
2h = 1 - 6
2h = -5
h = -5/2
h = -2.5

A city's population is currently 100,000. If the population doubles every 80 years, what will the population be 160 years from now?
Answer:
Step-by-step explanation:
100,000 doubles to 200,000 in 80 years then 400,000 in 80 more years
400,000 because it doubles once first 80 years to 200,000 then again another 80 years to 400,000
For which equations is the solution for x the same number?
i. 15 - X = -3
ii. x/2 + 6 = 15
iii. -1/3x - 5.7 = 0.3
O A. i and ii
O B. i and iii
O C. ii and iii
O D. i, ii and iii
O E. none of the questions
Answer:
A. i and ii
Step-by-step explanation:
i) 15 - x = -3
x=18
ii) x/2 + 6 = 15
x/2 = 9
x= 18
iii) -1/3x -5.7 = 0.3
-1/3x = 6
x = -18

Stojan has money automatically deposited into a savings account each week. After 2 weeks, he has $14. After 4 weeks he has $28. The unit rate is measured in dollars per week. What is the constant proportional?
Answer:
7
Step-by-step explanation:
HeLLPP! Sean and Mason run out of gas while fishing from their boat in the bay. They set off an emergency flare with an initial velocity of 35 meters per second. The height of the flare in meters can be modeled by h(t)=−5t2 + 35t, where t represents the number of seconds after the launch. How long will it take the flare to get to 30 meters?
Remember to only enter a number. Also, you will get two answers--I want to know when it will first get to 30 meters.
Answer:
So it will reach the 30 meter mark at 1.7 seconds

Step-by-step explanation:
let f(x)= p+ 8/x-q. the line x=4 is a vertical asymptote to the graph of f. what is the value of q and p, if the y intercept is (0,4)?
Answer:
The value of q and p is 4 and -24 respectively.
Step-by-step explanation:
Being [tex]f(x)=\frac{p+8}{x-q}[/tex] , the line x=4 is a vertical asymptote to the graph of f(x). The line r is an asymptote of a function if the graph of the function is infinitely close to the line r. That is, an asymptote is a line to which a function approaches indefinitely, without ever touching it.
Being a rational function that which can be expressed as the quotient of two polynomials, a vertical asymptote occurs when the denominator is 0, that is, where the function is not defined. In this case:
x - q= 0
Solving:
x= q
Being the line x=4 the vertical asymptote, then
4=q
Then the function f (x) is:
[tex]f(x)=y=\frac{p+8}{x-4}[/tex]
The y intercept is (0,4). This is, x= 0 and y=4. Replacing:
[tex]4=\frac{p+8}{0-4}[/tex]
Solving:
[tex]4=\frac{p+8}{-4}[/tex]
4*(-4)= p+8
-16= p+8
-16 - 8= p
-24= p
The value of q and p is 4 and -24 respectively.
Find the greatest common factor between 18 and 60? Help me or I die.....Jk help me plz
Step-by-step explanation:
I dont know the answer exactly but to find the greatest common factor you have to find out like the numbers that go into the timetable your talking about like e.g a factor of 18 would be 6,3,2 etc. once you have done that between both of them then you have to find the same numbers between them. and that's the answer. hope it helped I'm not exactly good at explaining

Jeff has two sticker-printing machines. Each machine can print 42 stickers per minute. On day 1, only the first machine was used, and it printed 89 stickers. On the following day, the first machine printed for x minutes and the second machine printed for y minutes. Which expression shows the total number of stickers printed by both machines during these two days? (1 point) a 131x + 42y b 42 + 89x + y c 89 + 42x + 42y d 89x + 84y
Answer:
c 89+42x+42y
Step-by-step explanation:
On day 1 :
First Machine= 89 stickers
Second Machine= none
On day 2 :
First Machine= ? stickers ( if in 1min = 42stickers
x min=?
( x min/1 min × 42stickers)
=42x stickers.
Second Machine=?stickers ( if in 1min = 42stickers
y min=?
( y min/1 min × 42stickers)
=42y stickers.
Total = 89 + 42x + 42y

The perimeter of a flower garden with three sides is 46 feet. One side of the garden is 11 feet long. Another side of the garden is 13 feet long. What is the length of the third side? Enter your answer in the box. feet
Answer:
22ftStep-by-step explanation:
Step one:
given that the orientation of the garden is a triangular shape(it has three sides)
the perimeter is given as=46ft
one side y=11ft
the second side z= 13ft
let the third side be xft
Step two:
the expression for the perimeter = z+y+x
46=11+13+x
46=24+x
solve for x
x=46-24
x=22ft
Therefore the third side is 22ft long

She rounded her estimation up.
Step-by-step explanation:
Shannon paid $57.25 for 28 pounds ($57.25÷28=2.0446428571)
If you round the answer to the nearest dollar, you'll look at the number in the tenths place (0). Zero is not 5 or greater. That makes the 2 stay the same.
A container of water holds 128 fluid ounces. Toya drinks 8 fluid ounces of water every hour. How many fluid ounces are in the container after 8 hours
Answer: 64 fluid ounces
Step-by-step explanation:
Amount of water in the container = 128 fluid ounces
Amount drank by Toya every hour = 8 fluid ounces
For 8 hours, Toya would have drank:
= 8 × 8 fluid ounces
= 64 fluid ounces
To calculate the amount of fluid ounces
thataree in the container after 8 hours, we then subtract 64 fluid ounces from 128 fluid ounces. This will be:
= 128 fluid ounces - 64 fluid ounces
= 64 fluid ounces
Math question plz help me
Answer:
The required equation of the line is:
[tex]y=\frac{1}{4}x-1[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-4x+3[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -4.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1=\frac{1}{4}\left(x-8\right)[/tex]
add 1 to both sides
[tex]y-1+1=\frac{1}{4}\left(x-8\right)+1[/tex]
[tex]y=\frac{1}{4}x-1[/tex]
