Answer:
x = 3, y = 1
Step-by-step explanation:
By substitution since y = -2x + 7, substitute that for the 2nd y so
-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1
If you use elimination you can subtract the two equations from each other to get rid of the y so
y = -2x + 7
-y = -3x + 8
so 0 = -5x + 15, 5x = 15, x=3

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

1. The amount paid for different weights of oranges at a farmer’s market are shown below. Oranges (lb) Price ($) 2 3 3 4.50 5 7.50 ? 12 (a) Is the relationship between the price and the weight of the oranges proportional? Use the first three rows of data to answer this question. Show your work and explain. How many pounds of oranges cost $12? Show your work.
due today.
Answer:
Relationship is proportional ;
8 oranges
Step-by-step explanation:
Oranges (lb) 2 ___ 3 ____5 ___?
Price ($) __ 3 ___4.50___7.50_12
For proportionality :
Oranges = k * price
Where, k = constant of proportionality
2 = 3k
k = 2 /3
k = 0.666666
Using k :
Number of oranges at price = 4.50 should be:
0.66666 * 4.50 = 3
Number of oranges at price = 7.50 should be:
0.66666 * 7.50 = 5
Hence, relationship is proportional
Number of oranges at $12
0.66666 * 12 = 8
Adele believes that 0.462 is written as "four tenths, sixty-two hundredths." Is she correct? Explain your answer. *
Answer:
Adele is not correct.
Step-by-step explanation:
The statement in itself wields an incorrect answer. However, when she states "sixty-two hundredths" it is further proven incorrect. This is because the 0.062 part of the total 0.462 would be pronounced as 62 thousandths.
Therefore, Adele is incorrect. The correct answer, however, would be: "Zero and four-hundred sixty-two thousandths."

What is the proportion of 36 / x equals 8/7
Answer:
Step-by-step explanation:
Multiply all terms by the same value to eliminate fraction denominators
36/x=8/7
x times 36/x=x times 8/7
Cancel multiplied terms that are in the denominator
cancel both x’s for you should have 36=x times 8/7
Combine multiplied terms into a single fraction
36=8x/7
Multiply all terms by the same value to eliminate fraction denominators
36=8x/7 so you multiply 7 times 36=7 times 8x/7
so you simplify so you get 252=8x
then you Divide both sides of the equation by the same term
252=8x 252/8=8x/8 so you get 63/2
so your final answer is x=63/2

Step-by-step explanation:
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{6\sqrt{3} }{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]
cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]
tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{6\sqrt{3} }{6}[/tex] = [tex]\sqrt{3}[/tex]

Try adding the percent of 5.
Step-by-step explanation:
(5 percent off 19.00 is 18.05 The difference is 0.95)
It might be ADDING in the situation
cause 19.00 + (5percent) = 19.95
Why: I think its adding a percent of 5
Because clue content.. And the clue was (total cost with service fee)
(total) is one of the context clues for addition or adding.
and it adding service fee.
so it wants an addition of the total cost with service fee.

Answer:
the total amount collected is 2,665
Step-by-step explanation:
The computation of the total amount collected is shown below:
= price × number of tickets sold × price + number of tickets sold × price + price
= 14 × 15 × 10 + 56 × 10 + 5
= 2,100 + 560 + 5
= 2,665
Hence, the total amount collected is 2,665
Ron works 8 hours a day, 5 days a week, $15 dollars an hour, for 12 weeks.
What is his gross pay?
Answer:
If Ron works 8 hours a day and get's paid $15 an hour
for 5 days a week and works for 12 weeks
1 hour = $15
8 hours = $120
So Ron get's paid $120 a day
So if he works 5 days a week then
120 x 5 = $600
Ron get's paid $600 a week
So if Ron works for 12 weeks then
600 x 12 = $7,200
Ron's gross pay is $7,200

Jen has 3 bags of pears. Each bag has 5 pears. If Jen gives the same number of pears to 4 friends, how many pairs will each friend get?
Answer:
3 pears each
Step-by-step explanation:
3 bags of pears
5 pears in each
1=5
2=5
3=5
thats 15 pears
15/4=3.75 (so its just 3)
The number of pears each friend get will be 3.75 pears for each friend.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Jen has 3 bags of pears. Each bag has 5 pears. Then the total number of the pears will be given by the multiplication of the numbers 3 and 5.
Total pears = 3 x 5
Total pears = 15 pears
If Jen gives the same number of pears to 4 friends.
Then the number of pears each friend gets will be
⇒ 15 / 4
⇒ 3.75 pears for each friend
Thus, the number of pears each friend get will be 3.75 pears for each friend.
