Thisss one toooo plsss
Answer:
5
Step-by-step explanation:
x + y = 3
xy = 2
x = 1 and y = 2 or x = 2 and y = 1
x + y = 1 + 2 = 3
xy = (1)(2) = 2
y^2 + x^2 = (2)^2 + (1)^2 = 4 + 1 = 5
HELP PLS :)))) could you also explain how you got the answer thanksss!:)))))
A box contains 5 purple marbles, 3 green marbles and 2 orange marbles. You draw the first marble, return it to the box and draw a second marble. What is P(both marbles are orange)?
Answer:
1/15
Step-by-step explanation:
1/5+3+2 all of the marbles
2/10 odds of drawing an orange marble(bc 2 orange marble)
3/9 because to get 3 green and 1 marble is removed and 9 is total marbles left
2/10*3/9=1/15 muliply odds because 2 draws of marbles
Solve
4x+3/7+2=x+5/2
Answer:
x= 1/42
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+3/7+2=x+5/2
combine like terms (2 and 3/7)
4x+17/7=x+5/2
Step 2: Subtract x from both sides.
4x-x+17/7=x-x+5/2
3x+17/7=5/2
Step 3: Subtract 17/7 from both sides.
3x+17/7−17/7=5/2-17/7
3x=1/14
Step 4: Divide both sides by 3.
3x/3=1/14/3
1/14 * 1/3 = 1/42
x=1/42

A gum tree reached a height of 150 ft in 15 years. Cathy and Darla write different equations to find the yearly average growth g of the tree. Cathy writes 15g = 150. Darla writes 150/15 = g. Do these equations have the same solution? Explain.
Answer:
Yes, they have the same answer because because 150/15 = 10 and in the equation 15g = 150, you have to solve it by dividing 150 by 15 which gets 10. Therefor, they are the same.
Step-by-step explanation:
Answer: They have the same solution.
Step-by-step explanation: 15g=150 has an answer of 10 ft. (divide 150 by 15 to get g alone.) 150/15=g has an answer of 10 as well. (Simplify to find g.)

For the diagram below let m∠1 = (7x + 5)°, m∠2 = (9x − 8)°, and m∠3 = (11x − 15)°. A triangle with exterior angles 1, 2, 3. Complete the work shown to find the m∠3. Set the sum of the exterior angles to 360° and solve for x. 7x + 5 + 9x − 8 + 11x − 15 = 360 27x − 18 = 360 27x = 378 x = 14 Substitute the value of x into the expression that represents mAngle3. mAngle3 = 11(14) – 15 mAngle3 = °

what is the cost of the item that would make these discount equivalent?
Discount:
30% off $22.50 off
Answer:
$15.75
Step-by-step explanation:
Turn the percentage into a decimal.
30% = 0.3
Multiply.
22.5 * 0.3 = 6.75
Subtract.
22.5 - 6.75 = 15.75

Mr. Johnson currently has a square garden. He wants to redesign his garden and make it into a rectangle with a length that is 5 feet shorter than three times its width. He decides the perimeter should be 70. PLEASEEEEE ITS URGENT
Answer:
Width of the rectangle = 10 feet
Length of the rectangle = 25 feet
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Width of the rectangle = x feet
Length of the rectangle = 3x - 5 feet
Perimeter of the rectangle = 70 feet
Perimeter of a rectangle = 2(length + width)
70 = 2{x + (3x - 5)}
70 = 2{x + 3x - 5}
70 = 2(4x - 5)
70 = 8x - 10
70 + 10 = 8x
80 = 8x
Divide both sides by 8
x = 80 / 8
= 10
Width of the rectangle = 10 feet
Length of the rectangle = 3(10) - 5
= 30 - 5
= 25 feet
What is f(−1) for the function given? f(x)=x2−3x+8
Answer:
12
Step-by-step explanation:
I am assuming you are asking for f(x)=x^2-3x+8? You plug (-1) in for all portions of x. This means you get (-1)^2-3(-1)+8. (-1)^2 is simply 1 because -1 x -1=1. 3*-1 is -3. This makes the equation 1 - (-3) + 8. The middle section simplifies down to +3 making it 1+3+8, or 12.

Answer:
329/9, the answer seems wrong but I triple checked because I thought so too. The answer is 100% correct
Step-by-step explanation:
Angle EFG + Angle FGH + Angle GEF = 180 degrees
(2x+1) + (6x+2) + (x + 19) = 180 degrees
9x + 22 = 180 degrees
9x = 158 degrees
x= 158/9
x+19 = Angle GEF
158/9 + 19 = Angle GEF
329/9 =Angle GEF
Double check:
(2x+1) + (6x+2) + (x + 19), x=158/9
2(158/9) + 1 = 325/9
6(158/9) +2 = 322/3
(158/9) +19 = 329/9
325/9 + 322/3 + 329/9 = 180
