Solve the system of equations.
Y=9x-17
y = x + 23

Solve The System Of Equations.Y=9x-17y = X + 23

Answers

Answer 1

Answer:

y=9x-17; x=17/9 or x=1 8/9 or x=1.8

y=x+23; x= -23

Step-by-step explanation:

y=9x-17

0=9x-17 (Move variables to the left-hand side and change its sign)

-9x=-17 (Divide both sides of the equation by -9)

x=17/9, x=1 8/9, or x=1.8

y=x+23

0=x+23 (To find x-intercept/zero, substitute y=0)

-x=23 (Move variable to the left-hand side and change its sign)

x= -23 (Change the signs on both sides of the equation)

x= -23

Answer 2

Answer:

x = 5

y = 28

the expressions both equal y so they are equal to each other.  so you right the equation as

9x - 17 = x + 23

then you subtract x from both sides

and then add 17 to both sides

the final step is to divide 8 on both sides and that gives you the answer x = 5. then you plug that back into the problem so...

y = 5 +23

so y = 28.

hope this helped!

In the equation 6x - 2 = -4x + 2, Spencer claims that the
first step is to add 4x to both sides. Jeremiah claims that
the first step is to subtract 6x from both sides. Who is
correct? Explain.

Answers

Answer:

Spencer is correct

Step-by-step explanation:

Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer

Answer:

Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.

Fun Zone charges an entrance fee
of $4.50 and $0.65 per ticket. Happy
Town charges $0.40 per ticket and a
$5.00 entrance fee. How many
tickets must be purchased in order
for the total to be the same at both
Fun Zone and Happy Town?

Answers

Answer:

2 tickets

Step-by-step explanation:

To be the same they must equal each other.

4.50 + 0.65x = 0.40x + 5

isolate the variable

subtract 4.50 from both sides

0.65x = 0.40x + 0.50

subtract 0.40x from both sides

0.25x = 0.50

divide both sides by 0.25

x = 0.50 ÷ 0.25

A side of the triangle below has been extended to form an exterior angle of 164º. Find the value of x.​

Answers

Answer:

x=50

Step-by-step explanation:

The value of the angle of the triangle 'x' will be 111°.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The sum of the two interior angles of the triangle is equal to the exterior angle of the triangle.

x + 53° = 164°

Simplify the equation, then we have

x + 53° = 164°

x = 164° - 53°

x = 111°

The value of the angle of the triangle 'x' will be 111°.

Answers

Answer:

4w +7 = 5

Step-by-step explanation:

Have a nice day.

Answer:

4w + 7 = 5

Step-by-step explanation:

"sum" means addition (+), so we're to add two items:

item 1 to be added

"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).

Therefore, 4 x w = 4w

item 2 to be added

This is the number 7

The sum

4w + 7

Now, the sum, equals(=)  the number 5, therefore answer:

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that the two inequalities are -2m + 7 < 13 or 5m + 12 > 37. The inequalities will be solved as,

-2m+7<13

-2m<6

m<-3

A television set can be purchased with a $200 down payment plus a $39.99 monthly payment. Alternatively, the television can be purchased with no money down and monthly payments of $59.99. Solve for the number of months until the payments are of equal value.

Answers

Answer:

10 months

Step-by-step explanation:

Let x denotes number of months.

Down payment of first TV = $200

Per month payment of first TV = $39.99

Total payment of first TV [tex]=200+39.99x[/tex]

Down payment of second TV = $0

Per month payment of second TV = $59.99

Total payment of second TV [tex]=0+59.99x=59.99x[/tex]

To find number of months until the payments are of equal value,

solve [tex]200+39.99x=59.99x[/tex]

[tex]200+39.99x=59.99x\\200=59.99x-39.99x\\200=20x\\x=\frac{200}{20}\\ x=10[/tex]

So, payments become of equal value after 10 months.
