Answer:
y=5/2x+13.5
Step-by-step explanation:
5x-2y=10
-2y=-5x+10
y= 5/2x-5
y-6=5/2(x+3)
y-6=5/2x+ 7.5
y=5/2x+13.5
Answer:
Step-by-step explanation:
First you must isolate y in the given equation
5x - 2y = 10 Subtract 5x from both sides
-2y = -5x + 10 Divide both sides by - 2
y = -5/-2 x + 10 / -2
y = 2.5 x - 5 The new equation has a slope of 2.5
x = - 2
y = 6
y = 2.5x + b
6 = 2.5*-2 + b
6 = -5 + b Add 5 to both sides
6+ 5 = b
b = 11
Answer: y = 2.5x + 11

x^2=5 using exponents
Answer:
±√5 are the solutions to x^2=5
Step-by-step explanation:
Write out x^2=5. Now enclose each of the two sides in parentheses. Apply the exponent (1/2) to both sides:
(x^2)^(1/2) = (5)^(1/2)
The left side simplifies to x and the right side to ±√5.
So ±√5 are the solutions to x^2=5.

I will give Brainliest to the first person
Please explain step by step.
Answer:
(- 1, 3 )
Step-by-step explanation:
y = - x + 2 → (1)
3x - y = - 6 → (2)
Substitute y = - x + 2 into (2)
3x - (- x + 2) = - 6 ← distribute parenthesis and simplify left side
3x + x - 2 = - 6
4x - 2 = - 6 ( add 2 to both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Substitute x = - 1 into (1)
y = - (- 1) + 2 = 1 + 2 = 3
solution is (- 1, 3 )

Sukriti sold two bicycles at Rs.3750 each. She gained 25% in first
bicycle and lost 25% on another bicycle. How much does she loss
or gain in the total price?
Answer:
Rs. 500 lossStep-by-step explanation:
SP is 3750
First case, 25% gain with CP of x:
3750 = 1.25xx = 3750/1.25x = 3000Gain amount:
3750 - 3000 = 750Second case , 25% loss with CP of x:
3750 = 0.75xx = 3750/0.75x = 5000Loss amount:
5000 - 3750 = 1250Total loss is the difference between gain and loss:
1250 - 750 = 500You are saving money for a new bicycle, which costs $85.99. So far you have saved $47.52. How much more money do you need before you can purchase the new bicycle

Under her cell phone plan, Avery pays a flat cost of $58.50 per month and $5 per gigabyte. She wants to keep her bill at $64.50 per month. Write and solve an equation which can be used to determine x, the number of gigabytes of data Avery can use while staying within her budget.
Answer:
x=1
Step-by-step explanation:
64.50=5x+58.50
64.50=5(1)+58.50
64.50=63.50 CORRECT
It can't be 2 because it will be over 64.50
5(2)+58.50
10+58.50
68.50 WRONG
Avery can use up to 1.2 gigabytes of data while staying within her budget of $64.50 per month.
The equation to determine the number of gigabytes of data Avery can use while staying within her budget can be written as:
$58.50 + $5x = $64.50
Where:
$58.50 represents the flat cost per month
$5x represents the cost based on the number of gigabytes used (x gigabytes)
$64.50 is the total budget she wants to stay within
To solve for x, we can subtract $58.50 from both sides of the equation:
$5x = $6.00
Then, divide both sides by $5:
x = 1.2
So, Avery can use up to 1.2 gigabytes of data while staying within her budget of $64.50 per month.

Step-by-step explanation:
Given :- A taxi service charges $1.00 for the first 1/10 mile then $0.10 for each additional 1/10 mile after that. How much does it cost to go 2 miles in the taxi ?
Solution :-
→ charge for first (1/10) mile = $1
then,
→ distance left = 2 miles - (1/10) miles = (20 - 1)/10 = (19/10) miles .
Now,
→ charge for each additional 1/10 mile = $0.10
then,
→ charge for each additional 1 mile = $(0.10 * 10) = $1
So,
→ charge for each additional 19/10 mile = 1 * (19/10) = $(1.9)
therefore,
→ Total cost for 2 miles = 1.9 + 1 = $2.9 (Ans.)

Two boats leave the same marina. One heads north, and the other heads east. After some time, the northbound boat has traveled 16 miles, and the eastbound boat has traveled 12 miles. How far apart are the two boats?
Answer:
Equation:
y = x+1
Distance Equation:
sqrt[x^2 + y^2] = 5
===========================
Substitue for "y" and solve for "x":
sqrt[x^2 + (x+1)^2] = 5
x^2 + x^2 + 2x + 1 = 25
2x^2 + 2x -24 = 0
x^2 + x - 12 = 0
Factor:
(x+4)(x-3) = 0
x = 3 miles (eastbound distance)
x+1 = 4 miles (southbound distance)

Step-by-step explanation:
Address formula, input values.

7 /6 & 4
7/6 ÷ 4= ?
Multiply 7/6 with reciprocal of 4
= 7/6 x 1/4
= 7/24The simplified form of the provided expression "7/6 divided by 4" is 7/24.
To simplify the expression 7/6 divided by 4, we can follow these steps:
First, let's represent the division as a fraction by placing the numerator (7/6) over the denominator (4): (7/6) / 4.
To divide fractions, we can multiply the numerator of the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 4 is 1/4.
Thus, we have (7/6) x (1/4).
To multiply the fractions, we multiply the numerators together and the denominators together. So, (7 x 1) / (6 x 4) = 7/24.
Therefore, the simplified form of 7/6 divided by 4 is 7/24.
