Answer:

B. 11+11=10+12

Step-by-step explanation:

11+11 is 22

And 10+12 is 22

So the statement is true because both sides are equal

Answer:

From the graph, it is clear that the point of intersection is:

And the x-coordinate of the point of intersection for the two lines is:

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}2x+y=-9\\ 2x-5y=-3\end{bmatrix}[/tex]

solving the system of equations

subtracting 2x+y = -9 from 2x-5y = -3

[tex]2x-5y=-3[/tex]

[tex]-[/tex]

[tex]\underline{2x+y=-9}[/tex]

[tex]-6y=6[/tex]

so

[tex]\begin{bmatrix}2x+y=-9\\ -6y=6\end{bmatrix}[/tex]

solving for y

[tex]-6y=6[/tex]

Divide both sides by -6

[tex]\frac{-6y}{-6}=\frac{6}{-6}[/tex]

[tex]y=-1[/tex]

[tex]\mathrm{For\:}2x+y=-9\mathrm{\:plug\:in\:}y=-1[/tex]

[tex]2x-1=-9[/tex]

[tex]2x=-8[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{-8}{2}[/tex]

[tex]x=-4[/tex]

Thus, the x-coordinate of the point of intersection for the two lines below will be:

[tex]x=-4[/tex]

Also, the graph is attached.

From the graph, it is clear that the point of intersection is:

And the x-coordinate of the point of intersection for the two lines is:

Answer:

y=1.125x

Step-by-step explanation:

9/8 is the ratio

so, I would do 9/8 which is 1.125. so, one euro is worth 1.125 dollar

y(dollars)=1.125x(euros)

TEST

27 dollars=1.125 • 24

Answer:

Step-by-step explanation:

3x^2+(7-3)+6x

3x^2+6x+4

Answer:

x = -8

y = 5

Step-by-step explanation:

2x = -3y-1

x = (-3y-1)/2

3x + 4y = -4

3[(-3y-1)/2]+4y = -4

(-9y-3/2)+4y = -4 (x2 all)

-9y-3+8y = -8

-9y+8y = -8+3

-y = -5

y = 5

3x+4.5 = -4

3x+20 = -4

3x = -24

x = -8

checking:

2.(-8)+3.5 = -1

-16+15 = -1 (checked)

Answer:

x= 4 or -4

Step-by-step explanation:

take the root of both sides then solve

Answer:

x = 50°

Step-by-step explanation:

According to exterior angle property of a traingle , measure of exterior angle is equal to sum of it's two interior angles of the triangle. So,

[tex]x = 15 + 35 = 50[/tex]

Answer:

X < 6

Step-by-step explanation:

Add 8 to both sides

x < 6

Answer:

X<6

Step-by-step explanation:

x-8<-2

So first off, you want to get X by itself. To do that you have to do the opposite of what the number is. If the number is negative you add it. If the number is positive, you subtract it. What you do on one side, you do on both.

x-8<-2

+8      +8

X<-2+8

Next, You need to add alike terms.

X<6

Step 1: Define Systems

y + 5x = 1

5y - x = 5

Step 2: Rewrite Systems

y + 5x = 1

Step 3: Redefine Systems

y = 1 - 5x

5y - x = 5

Step 4: Solve for x

Step 5: Solve for y

Answer:

- 4, 13, - 21, 47

Step-by-step explanation:

Using the recursive rule and a₁ = - 4 , then

a₂ = - 2a₁ + 5 = - 2(- 4) + 5 = 8 + 5 = 13

a₃ = - 2a₂ + 5 = - 2(13) + 5 = - 26 + 5 = - 21

a₄ = - 2a₃ + 5 = - 2(- 21) + 5 = 42 + 5 = 47

Thus the first 4 terms are - 4, 13, - 21, 47

Answer:

Step-by-step explanation:

((3×5)+4)/5=

19/5

Answer:$5.75

Step-by-step explanation:

For the cube first we find the surface on one side which is 3x3=9ft^2

we have 6 sides 9x6=54ft^2

For the pyramid first we find the surface of the base which is 15x15=225in^2

next we find the surface of the sides which is 7*15/2=52.5in^2 52.5*4=210in^2

210+225=435in^2

Answer:

435 inches for pyramid 54ft for cube
