D (26, 10,400)
E (27, 10,600)
Answers
Answer:
b and d because with every month, he gains $400. and if you multiply the x-value by 400, the only two that have the correct y-value are b and d
a should be 8,800
c should be 9,600

4x+6y=−6
(6, −5)
(0, −12)
(3, −3)
(4, −7)
Answers
Answer:
(3, -3)Step-by-step explanation:
METHOD 1.Put the coordinates of the given points to the equations and check the equality.
[tex]\left\{\begin{array}{ccc}y=3x-12&(1)\\4x+6y=-6&(2)\end{array}\right[/tex]
for (6, -5)
(1)
-5 = 3(6) - 12
-5 = 18 - 12
-5 = 6 FALSE
for (0, -12)
(1)
-12 = 3(0) - 12
-12 = 0 - 12
-12 = -12 TRUE
(2)
4(0) + 6(-12) = -6
0 - 72 = -6
-72 = -6 FALSE
for (3, -3)
(1)
-3 = 3(3) - 12
-3 = 9 - 12
-3 = -3 TRUE
(2)
4(3) + 6(-3) = -6
12 - 18 = -6
-6 = -6 TRUE
for (4, -7)
(1)
-7 = 3(4) - 12
-7 = 12 - 12
-7 = 0 FALSE
ANSWER: (3, -3)
METHOD 2:Solve the system of equations:
[tex]\left\{\begin{array}{ccc}y=3x-12&(1)\\4x+6y=-6&(2)\end{array}\right[/tex]
substitute (1) to (2):
[tex]4x+6(3x-12)=-6\qquad|\text{use the distributive property}\\4x+(6)(3x)+(6)(-12)=-6\\4x+18x-72=-6\qquad|\text{add 72 to both sides}\\22x=66\qquad|\text{divide both sides by 22}\\\boxed{x=3}[/tex]
put it to (1):
[tex]y=3(3)-12\\y=9-12\\\boxed{y=-3}[/tex]
[tex]\left\{\begin{array}{ccc}x=3\\y=-3\end{array}\right[/tex]

Simplify 7(9x - 3) - 4(2x - 1)
34x
55x - 17
55x - 25
Answers
Answer:
the answer is the second one, 55x-17
Step-by-step explanation:
So what you do is you open the parenthesis and evaluate and simplify the expression.
Here is the simplification: (7)(9x)+(7)(−3)+(−4)(2x)+(−4)(−1)
=63x+−21+−8x+4
And reduce that further and you get 55x-17.

2) Orion buys 3 books for a total of $25.50. He pays $8 plus sales tax for each book. He wants

t
Answers
Answer: I think the Sales tax is 0.5 because 0.5 X 3 is 1.5, He paid $24 in total for the books so you would do 24 + 1.5 and get 25.50, So it would have to be 0.5 sales tax for one book. Sorry about my English.
Answer: the equation would be 3(t + 8) = 25.50 :)

write an equation in slope-intercept form when given the information:
slope = 0, goes through the point (-3 , 3)
Answers
Answer:
[tex]y=3[/tex]
Step-by-step explanation:
We are given the slope of the line and a point on the line.
So, we can utilize the point-slope form, given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
We know that the slope is 0. So, m = 0.
And we will let (-3, 3) be (x₁, y₁). Hence, by subsitution:
[tex]y-(3)=0(x-(-3))[/tex]
Simplify:
[tex]y-3=0[/tex]
We can add 3 to both sides. Hence, our equation is:
[tex]y=3[/tex]
As you would've expect, since it had a slope of 0, it is a horizontal line.

a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?
Answers
Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.
Creating a system of equations thus :
n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)Substitute for n and q
(q+3) + (q+6) + q = 36
3q + 9 = 36
3q = 36 - 9
q = 27 ÷ 3
q = 9 quarters
n = 9 + 3 = 12 nickels
d = 9 + 6 = 15 dimes
Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.
