Steps to solve:
-7x - 5y = -68 when x = -6
~Substitute and simplify
-7(-6) - 5y = -68
42 - 5y = -68
~Subtract 42 to both sides
-5y = -110
~Divide -5 to both sides
y = 22

1)
$24.82
O
$21.60
$25,44
The total cost of the leash will be $22.90. The correct option is A.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Kirk finds a dog leash with a price tag of $24 at a pet store. The leash is 10% off the original price. He must also pay 6% sales tax.
The cost after 10% off is:-
Cost = 24 - 24 x ( 10 / 100 )
Cost = 24 - 2.4
Cost = 21.6
Total cost after 6% sales tax = 21.6 + ( 21.6 x 0.06)
Total cost after 6% sales tax = 21.6 + 1.296 = $22.9
Therefore, the total cost of the leash will be $22.90. The correct option is A.

Raj is deciding between two cell phone plans, A and B, which are both linear functions. The monthly charge for plan A according to the number of minutes used is shown in the table. Monthly Charge for Plan A Minutes used, x Monthly charge ($), y 0 14.45 3 14.84 6 15.23 9 15.62 12 16.01 Plan B has the same monthly base charge as plan A, but it charges a different amount per minute used. If the total monthly charge for plan B is $22.10 when 45 minutes are used, what is the slope of the linear function that represents the cost of plan B?
Answer:
B
Step-by-step explanation:
The slope of the linear function for plan B is of $0.17.
---------------------------
A linear function has an equation in the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, measuring how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.---------------------------
Plan B has the same monthly base charge as plan A, that is, from the table, when [tex]x = 0, y = 14.45[/tex], and thus, (0, 14.45) is one of the points of the function.The monthly charge for 45 minutes is of $22.10, thus, another point is (45, 22.10).Given two points, the slope is given by the change in y divided by the change in x. Thus:[tex]m = \frac{22.1 - 14.45}{45 - 0} = 0.17[/tex]
The slope is of $0.17.

find three consecutive even integers if the third is 8 less than twice the second
Answer:
8, 10, 12
Step-by-step explanation:
Because they are even there is a whole number x so that (1st)2x, (2nd) 2x+2, and (3rd)2x+4 are the 3 consecutive integers.
so
If the third is 8 less than twice the 2nd then:
3rd = 2 (2nd) - 8
2x + 4 = 2 (2x+2) - 8
2x + 4 = 4x + 4 - 8
2x + 4 = 4x - 4 Add 4 to each side
2x + 4 + 4 = 4x - 4 + 4
2x + 8 = 4x Subtract 2x from each side
2x - 2x + 8 = 4x - 2x
8 = 2x Divide each side by 2
8/2 = 2x/2
8/2 = x
4 = x
No we plug into our equations to find the integers.
2x = 2(4) = 8
2x + 2 = 2(4) + 2 = 8 + 2 = 10
2x + 4 = 2(4) + 4 = 8 + 4 = 12
So our integers are 8, 10, 12
solve for k 4.5+1.5k=18−3k

Step-by-step explanation:
[tex] \sf{4.5 + 1.5k = 18 - 3k}[/tex]
Move 3k to left hand side and change it's sign
Similarly, move 4.5 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{4.5k = 18 - 4.5}}[/tex]
Subtract 4.5 from 18
[tex] \longrightarrow{ \sf{4.5k = 13.5}}[/tex]
Divide both sides by 4.5
[tex] \longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}[/tex]
Calculate
[tex] \longrightarrow{ \sf{k = 3}}[/tex]
Hope I helped!
Best regards! :D
Answer:
k = 3
Step-by-step explanation:
Subtract 4.5 from both sides:
4.5 + 1.5k = 18 - 3k
-4.5 -4.5
1.5k = 13.5 -3k
Subtract -3k from both sides:
1.5k = 13.5 - 3k
+3k +3k
4.5k = 13.5
Now simplify:
4.5k = 13.5
k = 3

Please use method of substitution numbers 9;10;11;12
Answer:
1. x = 1, y = 2.
12. x = 1, y = -3.
Step-by-step explanation:
I won't do all these for you, just the first and the last. The method is similar for all 12.
1.
y = x + 1
x + y = 3
Substitute y = x + 1 into the second equation:
x + y = 3 so:
x + (x + 1) = 3
2x + 1 = 3
2x + 1 -1 = 3 - 1
2x = 2
x = 1.
Now substitute x = 1 into the first equation to get the value of y:
y = x + 1
y = 1 + 1
y = 2.
12.
4x = y + 7
3x + 4y + 9 = 0
Solve for y in the first equation:
4x = y + 7 Subtract 7 from both sides of the equation:
4x - 7 = y + 7 - 7
y = 4x - 7.
Now substitute y = 4x - 7 in the second equation:
3x + 4y + 9 = 0 so:
3x + 4(4x - 7) + 9 = 0
3x + 16x - 28 + 9 = 0
19x - 19 = 0
19x - 19 + 19 = 0 + 19
19x = 19
x = 19/19 = 1.
Now substitute x = 1 in the first equation:
4x = y + 7
4*1 = y + 7 Subtract 7 from both sides of the equation:
4 - 7 = y + 7 - 7
-3 = y.

What is the slope of the line 4x – 2y = 5?
Answer:
y =2 x − 5/ 2
is this a right triangle?
The only way to really tell is to check it with the Pythagorean Theorem.
The Pythagorean Theorem describes every right triangle, and every triangle that fits the Pythagorean Theorem has a right angle in it. Guaranteed. This is incredibly handy.
If this IS a right triangle, then
(one leg squared) + (the other leg squared) = (the hypotenuse squared) .
Let's check it out:
-- One leg squared = (11 cm)² . That's 121 cm² .
-- The other leg squared = (√99 cm)² . That's 99 cm² .
-- Their sum is (121 + 99) cm² . That's 220 cm² .
-- The hypotenuse squared is (15 cm)² . That's 225 cm² .
Is 220 cm² equal to 225 cm² ?
NO ! They are not equal. They are different !
The sum of the squares of the legs is NOT equal to the square of the hippopotamus.
==> This triangle does NOT fit the Pythagorean Theorem.
==> It is NOT a right triangle.
(The angle in the bottom corner is slightly bigger than 90°. But you can't tell by looking at it. It's so close that you can only tell by checkoing the lengths againt the Pythagorean Theorem.)

RS bisects TU at Q. If TQ=5k-9 and QU=15-x
Answer:
x = 4, TU = 22
Step-by-step explanation:
Given that TS bisects TU at Q , then
TQ = QU , substitute values
5x - 9 = 15 - x ( add x to both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Thus
TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22
