what is the slope of the graph of 2x - 5y =20
Answer:
2/5
Step-by-step explanation:
convert to slope-intercept form y=mx+b:
2x - 5y = 20
-5y = 20 -2x
y = -4 (-2/-5)x
y = 2/5x - 4
the slope of the graph represented by 2x - 5y = 20 is 2/5.
To find the slope of the graph represented by the equation 2x - 5y = 20, we need to rearrange the equation into slope-intercept form (y = mx + b), where m is the slope.
Let's start by isolating the term with y:
2x - 5y = 20
-5y = -2x + 20
Next, divide the entire equation by -5 to solve for y:
y = (2/5)x - 4
Comparing the equation with the slope-intercept form, we can determine that the slope (m) is 2/5. Therefore, the slope of the graph represented by 2x - 5y = 20 is 2/5.

A plumber charges a $50 fee plus $100 per hour to complete a plumbing job. The total amount spent on a plumbing job can be expressed by the function T(x) = 100x + 50 where x represents the number of hours spent on the plumbing job. The maximum time spent on one job per day is 8 hours. Find a reasonable domain and range for this situation.
Answer:
Between 150 and 800
T is between 150 and 800
Step-by-step explanation:
given information
charges=$50
charges per hour=$100
let the amount of time spent be x
therefore the function for the total amount is
T(x) = 100x + 50
we want to estimate the amount for 1 hour and 8 hours
for 1 hour we have
x=1
T(x) = 100x + 50
T(1) = 100(1)+ 50
T(1) = 150
for 8 hours we have
x=8
T(x) = 100x + 50
T(8) = 100(8)+ 50
T(8) = 800+50
T(8) = 850
the domain is between 150 and 800

Your first job is to babysit a couple of times a week. You charge a flatfee of $10 for transportation back and forth to the house plus $5.50per hour. Let t be the time in hours that you babysit. Write analgebraic expression to define the amount of money you will makefor t hours of work.
Answer:
5.50t + 10
Step-by-step explanation:
Total amount of money made will sum of
transportation fees and money charged for t hours of baby siting
Given
transportation fees of back and forth to the house = $10
also given that
fees of 1 hour babysitting = $5.50
we have to find fee for t hours baby sitting ,
fees of t hours babysitting = fees of 1 hour babysitting*t
fees of t hours babysitting = 5.50t
Total amount of money made = fees of t hours babysitting + transportation fees of back and forth to the house
Total amount of money made = 5.50t + 10
Thus,
algebraic expression to define the amount of money you will make for t hours of work is 5.50t + 10

Answer:
box 1, 4 and 5 are correct
Step-by-step explanation:
Box 1 is correct if you simplify the equation by multiplying both sides by 4. When you multiply the left side by 4 you end up with 56 + 8x since 4 times [tex]\frac{1}{4}[/tex] equals 1. The right side becomes 4 x 20 = 80. So 56 + 8X = 80. If you continue to solve for X, you first have to subtract 56 from both sides of the equal sign which looks like this: 56 - 56 + 8X = 80 - 56 which reduces down to 8X = 24. Dividing both sides by 8 then reduces that equation down to X = 3.
Box 4 is also correct. When you have an equation like [tex]\frac{1}{4}[/tex] (8x + 56), you have to multiple both numbers on the inside of the parentheses by the number on the outside of the parentheses. So the equation is ([tex]\frac{1}{4}[/tex] X 8x) + ([tex]\frac{1}{4}[/tex] X 56) which results in 2x + 14. The right side of the equal sign does not change so now you have
2x + 14 = 20. To get rid of the 14 on the left, you subtract 14 from both sides.
2x + 14 - 14 = 20 - 14. On the left, 14-14=0 so you end up with just 2x. On the right 20-14=6. So now you have the equation 2x = 6. If you continue to solve for x, you divide both sides of the equal sign by 2. This will give you x = 3. Same as what you get by solving for x in Box 1 above.
Box 5 is also correct. As you see above when you solve for X in both answers above, X = 3.

What is the corresponding angle or side?
Answer:
Number 1 would be FK
Number 2 would be SQR
Answer:
1) FK
2) SQR
Step-by-step explanation:
In congruence statements such as these, each letter's position corresponds to the letter in the same position on the other side.
For example, in 1, MK corresponds to FK because M and F are in the same position and K is in the same position as itself (reflexive property).
In 2, FHG corresponds to SQR because each letter is in the same position in the given congruence statement.

Elizabeth withdrew $31 at a time from her bank account and withdrew a total of $279. Fran withdrew $46 at a time from her bank account and withdrew a total of $184. Who made the greater number of withdrawals? [ Select ] made the greater number of withdrawals, because she made [ Select ] withdrawals, while [ Select ] only made [ Select ] withdrawals.
Answer: See explanation
Step-by-step explanation:
Elizabeth withdrew $31 at a time from her bank account and withdrew a total of $279. This means Elizabeth withdrew ($279/$31) = 9 times.
Fran withdrew $46 at a time from her bank account and withdrew a total of $184. This means that Fran withdrew ($184/$46)= 4 times.
Therefore, Elizabeth made the greater number of withdrawals.
[Elizabeth] made the greater number of withdrawals, because she made [9] withdrawals, while [Fran] only made [4] withdrawals.

A′(3, -5), B′(1, -7), C′(3, -5)
D.
A′(-3, 3), B′(-1, 1), C′(-2, -3)
The missing figure is attached down
Answer:
The coordinates of the vertices of Δ A'B'C' are A' (-3, 3), B' (-1, 1), C' (-2, 3) ⇒ A
Step-by-step explanation:
If the point (x, y) reflected across the x-axis , then its image is (x, -y)
If the point (x, y) translated vertically up by k units then its image is (x, y + k)
Let us solve the question using the rules above
∵ The coordinates of Δ ABC are A (-3, 1), B (-1, 3), C = (-2, 1)
∵ Δ ABC reflected across the x-axis at first
→ By using the first rule above change the signs of y coordinates
∴ The image of A = (-3, -1)
∴ The image of B = (-1, -3)
∴ The image of C = (-2, -1)
∵ Then it translated 4 units up
→ Use the second rule above, where k = 4, add each y-coordinates by 4
∴ A' = (-3, -1 + 4)
∴ A' = (-3, 3)
∴ B' = (-1, -3 + 4)
∴ B' = (-1, 1)
∴ C' = (-2, -1 + 4)
∴ C' = (-2, 3)
The coordinates of the vertices of Δ A'B'C' are A' (-3, 3), B' (-1, 1), C' (-2, 3)
