Answer:
x-intercepts is (4,0)
y -intercepts is (0,-2)
Step-by-step explanation:
Using slope intercept form, x- intercept is (4,0) and y - intercept is (0,-2)
What is slope intercept form and how it can be used to find y and x intercept of the line?The slope intercept of a line is given by the equation y = m x+ c
y is y coordinate, x is x coordinate, m is the slope of the line
c is y- intercept of the line
y- intercept can also be found if a point on the line is given say (a, b) and slope is given .We put this point in the given slope intercept form and find c.
For finding x - intercept, put y = 0 in the equation and find value of x.
Given line -4x +8y = -16
Then add 4x both sides , we get
⇒4x+4x +8y = -16+4x
⇒ 8 y = 4x -16
Divide both sides by 8
⇒ y = (4/8) x - (16/8)
⇒ y = (1/2)x -2
Comparing this equation with y =mx+c
⇒ c =-2
Put y = 0 in the equation y = (1/2)x -2
⇒ 0 = x/2 -2
⇒2 = x/2
⇒4 =x
Therefore x- intercept is (4,0) and y - intercept is (0,-2)

You are a contractor and charge $90 for a site visit plus an additional $24 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $810 working at two separate work sites. Let the number of hours you work be y.
Answer:
x=29.66hrs
Step-by-step explanation:
Firstly, we can model the equation for the total cost as
Let y be the total cost
Let x be the number of hours
Y=98+24x
Also, given that you have earned $810
We can substitute Y=810 and solve for x
810=98+24x
810-98=24x
712=24x
Dividing both sides by 24
712/24=x
x=29.66hrs

Find the total distance from Mercury to Earth. HELP!
Answer:
5.67*10^7
Step-by-step explanation:
Since the distance from mercury to venus is 30,700,000, and the distance from venus to earth is 26,000,000, we can simply add these together to find the distance from mercury to earth:
30,700,000
+26,000,000
__________
56,700,000
Now, to convert it to scientific form, just multiply 10^7 (which is the number of digits-1) and 5.67. Therefore, the answer is 5.67*10^7

Find two numbers if their ratio is 9:11 and their difference is 6.
Answer:
Step-by-step explanation:
27,33
9*3 is 27
11*3 is 33
33-27 is 6
i only have one, sorry!
Answer:
Step-by-step explanation:
Let the larger number = y
Let the smaller number = x
x/y = 9/11
y - x = 6
Add x to both sides of the second equation
y = 6 + x
Substitute into the first equation
x/(x + 6) = 9/11
Cross multiply
11x = 9(x + 6)
Remove the brackets
11x = 9x + 54
Subtract 9x from both sides.
2x = 54
x = 54/2
x = 27
y = 27 + 6
y = 33
(27,33)
The way I've done it, there isn't a second pair.
I suppose you could do it this way.
9/11 = -27/-33
-27 - - 33 = 6
So the second pair could be
(-27, - 33)
Alright then! First question!
A graph has height (inches) on the x-axis and arm span (inches) on the y-axis. Points are at (30, 27), (45, 45), (53, 50), (60, 60), (67, 70), and (73, 72).
Identify if there is a relationship between the variables.
(A) No, there is no relationship because the points are all up and down.
(B) Yes, the relationship displayed shows arm span increasing as height increases.
(C) Yes, the relationship displayed shows arm span decreasing as height increases.
Answer:
hmmm...i wanna go with B
Step-by-step explanation:
because it goes from 30 to 45 and 45 and 45 to 53 to 50 then the 50 goes 60 meaning their both increasing as it it goes on
at least i believe im right haha hope this helped if its not to late
Answer: The answer is (B) Yes, the relationship displayed shows arm span increasing as height increases.

4b+14=22
solve the equation
Answer:
B= 2
Step-by-step explanation:
4b+14=22
-14 -14
4b=8
/4 /4
b=2
The value of b in the expression is,
b = 2
We have to given that,
An expression to simplify,
4b + 14 = 22
Now, We can simplify it as,
4b + 14 = 22
Subtract 14 both side,
4b + 14 - 14 = 22 - 14
4b = 8
Divide by 4;
b = 8/4
b = 2
Therefore, The solution of expression is,
b = 2

: Susan works as a hostess where she makes $8.75 per hour. She also babysits and earns $10.00 per hour. Last week she made $165.00. If she worked 6 hours more as a hostess than she did babysitting, how many hours did she babysit last week?
Answer:
She worked 12 hours as a babysitter and hours 6 as a hostess
Step-by-step explanation:
She woks 6 hours and gets 52.20 as a hostess so if she worked 6 hours as a babysitter then she would make 60 and 165-60=105 and since she worked 6 hours as a baby sitter than she has to work 12 hours as a hostess to make 105 we know that 105+60 =165.
