Answer:

x=-3 y=-5

Step-by-step explanation:

y = x + 8

X + y = 2

First take the first equation and input it into the second equation.

X+ (x+8)= 2

Now simplify

X+x+8=2

2x+8=2

    -8=-8

2x= -6

÷2   ÷2

x= -3.

Now that you have the x value, input it into the first equation to find y.

y= (-3) +8

y= -5

The solution to the given system of equations is x = -3 and y = 5.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The system of equations is given in the question:

y = x + 8  ...(i)

x + y = 2  ...(ii)

We have to determine the solution to the given system of equations.

Solving given equations using the substitution method.

First, substitute the value of the equation y = x + 8 in equation (ii), and solve for x:

x +  x + 8 = 2

2x + 8 = 2

2x = 2 - 8

2x = -6

x = -3

Now, substitute the value of the equation y = x + 8 in equation (ii), and solve for y:

y = -3 + 8

y = 5

Thus, the required solution is x = -3 and y = 5.

Answer:

Option A : 15x² + 62x + 63 is the correct answer.

Step-by-step explanation:

Given measurements of the figure are:

5x + 9 and 3x + 7

We have to find the area. We can find the area by multiplying the two expressions.

Area = (5x+9) * (3x+7)

Area = 5x (3x+7) +9(3x+7)

Area = 15x² + 35x + 27x + 63

Area = 15x² + 62x + 63

Hence,

Option A : 15x² + 62x + 63 is the correct answer.

Answer:

The first blank would be x=6

the other blank would be 9=4.5

Step-by-step explanation:

if you look at the table, you can see that when you insert a number as x (A.K.A the number "two") the number is divided by 2, so in the y row, its half the number that x was.

2÷1=1

4÷2=2

6÷2=3

7÷2=3.5

9÷2=4.5

Answer:

$2250

Step-by-step explanation:

First, find how much more Jayden will get each month by doing 2.5% of 5000, or multiplying 0.025 * 5000 = $125 per month.

Then, since Jayden is leaving it there for 18 months, you can do 125 * 18 = 2250.

The interest he will earn is $2250

Answer:

e=15.33

t=17.88

Step-by-step explanation:

e/9.1=9.6/5.7

cross multiply

5.7e=87.36

e=15.33

t/9.1=11.2/5.7

cross multiply

5.7t=101.92

t=17.88

Answer:

6x - 5 ≥ 8

Step-by-step explanation:

Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?

The inequality sign of

a) At least = greater than or equal to = ≥

Let us represent the number as = x

Hence: "five less than the product of a number and 6 is at least 8" can be written as:

= x × 6 - 5 ≥ 8

= 6x - 5 ≥ 8

Answer:

Cost of one senior citizen ticket = $11

Cost of one child ticket = $12

Step-by-step explanation:

Let,

x be the cost of one senior citizen ticket

y be the cost of one child ticket

According to given statement;

3x + 3y = 69      Eqn 1

5x + 3y = 91      Eqn 2

Subtracting Eqn 1 from Eqn 2

(5x+3y)-(3x+3y) = 91 - 69

5x+3y-3x-3y = 22

2x = 22

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{22}{2}[/tex]

x = 11

Putting x = 11 in Eqn 1

3(11) + 3y = 69

33 + 3y = 69

3y = 69 - 33

3y = 36

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{36}{3}\\y=12[/tex]

Hence,

Cost of one senior citizen ticket = $11

Cost of one child ticket = $12

Step-by-step explanation:

For the first one the equation is Y=2x+2 because look at rise over run which is 4/2 which is 4 divided by 2 which is 2

so the answer is Y=2x+2

The second one is, the points are (2,2) (3,3)
