x = 2y − 4
7x + 5y = −66
Answer:
Step-by-step explanation
Substitute 2y-1 for x in the second equation:
7x + 5y = -66
7(2y-4) + 5y = -66
then solve for y:
14y - 28 + 5y = -66
19y = -38
y = -2
Substitute -2 for y in the first equation:
x = 2y - 4
x = 2(-2) - 4
x = -8
The lines intersect at (-8,-2)

Find the value of x that makes the equation true 17 - 5(2x - 9) = -(-6x + 10) + 4
Answer:
i think x=4.75
Step-by-step explanation:
Answer:
17/4
Step-by-step explanation:
17−5(2x−9)=−(−6x+10)+4
17−5(2x−9)=−(−6x+10)+4
17+−10x+45=6x+−10+4
(−10x)+(17+45)=(6x)+(−10+4)
−10x+62=6x+−6
−10x+62=6x−6
−10x+62−6x=6x−6−6x
−16x+62=−6
−16x+62−62=−6−62
−16x=−68
-16x/16 = -68/16
x = 17/4

Book club A charges $20 for membership and $2 per book rental. Book club B charges $10 for membership and $3 per book rental. For how many movie rentals will the cost be the same at both book clubs? What does that cost?
Given:
Book club A charges $20 for membership and $2 per book rental.
Book club B charges $10 for membership and $3 per book rental.
To find:
The number of books for which the cost be the same at both book clubs.
Solution:
Let x be the number of books.
Book club A charges $20 for membership and $2 per book rental. So, the total cost is
[tex]C_1=20+2x[/tex] ...(i)
Book club B charges $10 for membership and $3 per book rental. So, the total cost is
[tex]C_2=10+3x[/tex] ...(ii)
Equating (i) and (ii), we get
[tex]10+3x=20+2x[/tex]
[tex]3x-2x=20-10[/tex]
[tex]x=10[/tex]
The total cost is
[tex]C_1=20+2(10)[/tex]
[tex]C_1=20+20[/tex]
[tex]C_1=40[/tex]
Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.

since P and Q share the same letter you're putting “A” in the middle where the two intersect. since U have B and Q have b we're putting it outside. so Q only supposed to have G. P is empty and U now have B,C,D,F,H.
p^1- p complement means everything outside of P so that will be b,c,d,f,g,h.

the product of two positive consecutive integers is five more than three times the larger integer. find the larger integer.
Answer:
When calculating consecutive integers, the smaller number is x and the larger number is (x + 1). This is because the sum of the consecutive integers are equal to 5 more than 3 times the larger integer. So the smaller number is -7 and the larger number is -6.
