Write in slope-intercept form (solve for y): 5x - 2y = 8
Answers
Answer:
y = 5/2 x - 4
Step-by-step explanation:
For slope-intercept form, just solve for y:
5x - 2y = 8
[tex]\frac{5x}{2} - \frac{8}{2} = \frac{2y}{2}[/tex]
5/2 x - 4 = y or
y = 5/2 x - 4
The slope intercept form is y= 5/2x - 4.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have the Equation
5x - 2y = 8.
As, we know from the slope intercept form
y= mx + b
So, 5x - 2y = 8
5x - 8 = 2y
5/2x - 8/2 = y
y= 5/2x - 4
where slope is 5/2 and y intercept is -4.

Amanda filled her gas tank three times last week. Here are the amounts of gas she bought (in gallons). 10.7,15 , 3.7 What is the total amount of gas Amanda bought last week?
Answers
Answer:
29.4 gallons
Step-by-step explanation:
Given that
the amounts of gas she bought (in gallons). 10.7,15 , 3.7
total amount of gas Amanda bought last week will be sum of 10.7 , 15 and 3.7
total amount of gas Amanda bought last week = 10.7 + 15 + 3.7
=> total amount of gas Amanda bought last week = 29.4
Thus, Amanda bought 29.4 gallons in total in last week.

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. In kilometers, How far did Andre run in 60 minutes ?
help ASAP
Answers
Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.

Answers
Let's solve for b.
x=−5−b+2x
Step 1: Flip the equation.
−b+2x−5=x
Step 2: Add -2x to both sides.
−b+2x−5+−2x=x+−2x
−b−5=−x
Step 3: Add 5 to both sides.
−b−5+5=−x+5
−b=−x+5
Step 4: Divide both sides by -1.

the sale tax rate on groceries in a certain state is 9% if the price of a grocery item before sales tax is g dollars, which expression represents the cost of the grocery item including sales tax?
Answers
Step-by-step explanation:
g + 0.09g = the final price
multiplying 0.09(9/100) with g will give you the tax
then you add it up to get the final cost.
The expression representing the cost of the grocery item including sales tax is 1.09g.
What is Percentage?Percentage is a dimensionless number and it has no measurement units.
It is usually denoted by the sign %. Sometimes it has also used in the abbreviated form 'pct.'.
Percentage of a number is the quotient of the number dividing with the whole and then multiply with 100. The reverse calculation can be done to find the number corresponding to a percentage.
Price of a grocery item before sales tax = g dollars
Sales tax rate on groceries = 9%
Amount of sales tax = 9% × g
= (9/100) × g
= 0.09 g
Total cost of the grocery = g + 0.09g
= 1.09g
Hence the total cost of the grocery item including sales tax is 1.09g.

Example 2: Leonardo saw the new sound system he wanted for $2623.95, including taxes. He had to buy it on
credit and had two options:
-
Use his new bank credit card, which has an interest rate of 14.5% compounding daily (Because the this
credit card is new, he has no outstanding balance from the previous month)
Apply for the store credit card, which offers an immediate rebate of $100 on the price, but has an interest
rate of 19.3%, compounded daily.
As with most credit cards, Leonardo would not pay any interest if he paid off the balance before the due date on
his first statement. However, he cannot afford to do this. Both cards require a minimum monthly payment of 2.1%
on the outstanding balance, but Leonardo is confident that he can make regular payments of $110.
Answers
Answer:
assuming 30 day months:
Leonardo can pay up to $110 per month
credit card
daily interest = 14.5% / 360 = 0.040278%
monthly interest = (1 + 0.040278%)³⁰ - 1 = 1.2154%
I prepared an amortization schedule using an excel spreadsheet
It will take Leonardo 29 months to completely pay off his debt. The last payment will only be $37. Leonardo will be able to save $65 on his last payment if he uses his credit card.
store credit
daily interest = 19.3% / 360 = 0.05361%
monthly interest = (1 + 0.05361%)³⁰ - 1 = 1.6209%
principal will be $100 lower, $2,523.95
I prepared an amortization schedule using an excel spreadsheet
It will also take Leonardo 29 months to completely pay off his debt, but the last payment will be $102, which is higher than the $37 that he would need to pay using a credit card.
