solve the simultaneous equation
Answer:
x = [tex]-\frac{11}{5}, 3[/tex]
y = [tex]-\frac{8}{5},1[/tex]
Step-by-step explanation:
3xy - y² = 8 -------(1)
x - 2y = 1 ------(2)
From equation (2),
x = 2y + 1
By substituting the value of x in equation (1),
3y(2y + 1) - y² = 8
6y² + 3y - y² = 8
5y² + 3y - 8 = 0
5y² + 8y - 5y - 8 = 0
y(5y + 8) - 1(5y + 8) = 0
(y - 1)(5y + 8) = 0
y = [tex]-\frac{8}{5},1[/tex]
From equation (2),
x = 2y + 1
For y = [tex]-\frac{8}{5}[/tex],
x = [tex]-2(\frac{8}{5})+1[/tex]
x = [tex]-\frac{11}{5}[/tex]
For y = 1,
x = 2(1) + 1
x = 3
Therefore, x = [tex]-\frac{11}{5}, 3[/tex]
y = [tex]-\frac{8}{5},1[/tex]

One health club charges a $40 membership fee and $40 per month. Another club charges a $100 membership fee and $25 per month. Write and solve an equation to find the number of months that it will take for the two health clubs to be equal
Answer:
After 4 months, the charges will be same.
Step-by-step explanation:
Membership charges of club one = $40
Per month charges = $40
Let,
x be the number of months
y be the total amount
y = 40x + 40
Membership charges of club two = $100
Per month charges = $25
y = 25x + 100
For equal charges, both equations will be same
40x + 40 = 25x + 100
40x - 25x = 100 - 40
15x = 60
[tex]\frac{15x}{15}=\frac{60}{15}\\x=4[/tex]
Therefore,
After 4 months, the charges will be same.

SOMEONE PLEASE HELP ME ASAP WITH THIS GEOMETRY PROBLEM
Answer: TVU is 51 degrees
Step-by-step explanation: The pre-image and new image are formed via a translation which is basically sliding. A translation is a rigid transformation, which means it preserve angles measures and sides length. So when we translate these two figures they are congruent. Using that logic, Segment AB translate to TU which means TU is 25 cm. Angle B translate to Angle U and Angle T was originally conguent to Angle A.
To find Angle V, we are going to use triangle interior angle theorem. 72+57+x=180
129+x=180
x=51

so 0.375 x 24 = 9 make me brainlist pls
Answer:
The answer is 9
Step-by-step explanation:
First, you wanna get rid of the fraction 3/8 so divide 3/8 or 3 ➗ 8 which will give you 0.375. Then multiply 0.375 to 24 to get your product.
Problem:3/8 x 24=?
Step 1:Turn fraction into a decimal
3 divided by 8 =0.375
Step 2:Multiply 0.375 to 24
0.375 x 24= 9
Answer:3/8 x 24=9

(2x -5) + (x) + (2x - 3) = 32.
5x-8 = 32.
ii) 5x-8=32
5x= 32+8
5x = 40
x= 40/5
x = 8
iii) 2x -5
2 × 8 -5 = 11.
2x-3
2×8-3
16-3 = 13
x =8
sides of the triangle= 8, 11, 13.
