Answer:D

y = -5/3x +4

Step-by-step explanation:

Answer:

y=0.25

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1.8−0.4y=2(1.1−y)

1.8+−0.4y=(2)(1.1)+(2)(−y)(Distribute)

1.8+−0.4y=2.2+−2y

−0.4y+1.8=−2y+2.2

Step 2: Add 2y to both sides.

−0.4y+1.8+2y=−2y+2.2+2y

1.6y+1.8=2.2

Step 3: Subtract 1.8 from both sides.

1.6y+1.8−1.8=2.2−1.8

1.6y=0.4

Step 4: Divide both sides by 1.6.

1.6y/1.6 = 0.4/1.6

Answer:

Student 3 had the greatest percentage error.

Step-by-step explanation:

Student 1

Actual length = 50in

Measured length = 49in

Error = 50 - 49 = 1

Error% = 1/50 × 100

= 1 × 2

= 2%

Student 2

Actual length = 100cm

Measured length = 110cm

Error = 100 - 110 = 10

Error% = 10/100 × 100

= 10 × 1

= 10%

Student 3

Actual length = 2cm

Measured length = 2.5cm

Error = 2 - 2.5 = 0.5

Error% = 0.5/2 × 100

= 0.5 × 50

= 25%

Student 4

Actual length = 10ft

Measured length = 9½ft

Error = 10 - 9½ = ½

Error% = ½/10 × 100

= ½ × 10

= 1 × 5

= 5%

Step-by-step explanation:

Answer:

The answer is 5 ( 6 + x ) = 20

Step-by-step explanation:

Five times = You are multiplying 5 to a number(s)

Sum of 6 and some number = Sum means to add. You are adding 6 to an unknown number.

In terms of x = You do not know what you are adding 6 with. Therefore 6+x.

is 20 = The total is 20.

To solve:

5 ( 6 + x ) = 20

30 + 5x = 20  Use the distributive property and multiply 5 to the 6 and the x

-30 + 5x = -30   Subtract the 30 on both sides

5x = -10              The 30's would cancel each other out and this is what's left

5x/5 = -10 / 5           Divide 5 on both sides.

x = -2                        The 5 cancels each other on the left side.

x = -2                        Is your answer

Hope this helps!

Answer:

a). y = 1.6x

b). Distance traveled = 115.2 feet

Step-by-step explanation:

From the graph attached,

A). Distance traveled by Kirk ∝ Duration of walk

    D ∝ t

    D = kt

    Or y = kx

    Since a point (5, 8) lies on the line given in the graph,

    8 = 5k

    k = [tex]\frac{8}{5}[/tex] = 1.6

    Therefore, equation will be,

    y = 1.6x

B). We have to find the distance walked after 72 seconds.

    By putting x = 72 seconds

    y = 1.6 × 72

       = 115.2 feet

    Distance traveled by Kirk = 115.2 feet

Answer:

12.07

Step-by-step explanation:

12×100=1200

1200+7=1207

1207÷100= 12.07

To find m,

m= Y2-Y1 / X2-X1

m= 10-5 / 4-2

m= 5/2

m= 2.5

To find b,

Use coordinate (4,10)

y=mx+b

10=2.5(4)+b

10=10+b

b=0

y=2.5x

the answer is y=2.5x

Answer:

The ordered pair (-6, -2) is in the solution set of the system of equations shown below ⇒ D

Step-by-step explanation:

To find the ordered pair that is in the solution set of the system of the equation substitute x and y in each equation by the coordinates of the ordered pair, if the two sides of equations are equal, then the ordered pair is in the solution set of the system of equations

∵ The equations are y² - x² + 32 = 0 ⇒ (1) and 3y - x = 0 ⇒ (2)

∵ The 1st ordered pair is (2, 6)

∴ x = 2 and y = 6

→ Substitute them in equation (2) first

∵ The left side = 3y - x

∴ The left side = 3(6) - 2 = 18 - 2 = 16

∵ The right sides = 0

∴ Left side ≠ Right side

∴ (2, 6) is not a solution to the system of equations

∵ The 2nd ordered pair is (3, 1)

∴ x = 3 and y = 1

→ Substitute them in equation (2) first

∵ The left side = 3y - x

∴ The left side = 3(1) - 3 = 3 - 3 = 0

∵ The right sides = 0

∴ Left side = Right side

→ Substitute them in equation (1)

∵ The left side = y² - x² + 32

∴ The left side = (1)² - (3)² + 32 = 1 - 9 + 32 = 24

∵ The right sides = 0

∴ Left side ≠ Right side

∴ (3, 1) is not a solution to the system of equations

∵ The 3rd ordered pair is (-1, -3)

∴ x = -1 and y = -3

→ Substitute them in equation (2) first

∵ The left side = 3y - x

∴ The left side = 3(-3) - (-1) = -9 + 1 = -8

∵ The right sides = 0

∴ Left side ≠ Right side

∴ (-1, -3) is not a solution to the system of equations

∵ The 4th ordered pair is (-6, -2)

∴ x = -6 and y = -2

→ Substitute them in equation (2) first

∵ The left side = 3y - x

∴ The left side = 3(-2) - (-6) = -6 + 6 = 0

∵ The right sides = 0

∴ Left side = Right side

→ Substitute them in equation (1)

∵ The left side = y² - x² + 32

∴ The left side = (-2)² - (-6)² + 32 = 4 - 36 + 32 = 0

∵ The right sides = 0

∴ Left side = Right side

∴ (-6, -2) is a solution to the system of equations

The ordered pair (-6, -2) is in the solution set of the system of equations shown below

Answer:

x = [tex]27.5^{o}[/tex]

Step-by-step explanation:

complementary angles are two or more angles whose sum is equal to [tex]90^{o}[/tex].

Thus given that;

m<BAM = x + 24

m<CTX = x + 11

So that,

m<BAM + m<CTX = 90

⇒ (x + 24) + (x + 11) = 90

x + 24 + x + 11 = 90

2x + 35 = 90

2x = 90 - 35

2x = 55

x = [tex]\frac{55}{2}[/tex]

 = 27.5

The value of x is [tex]27.5^{o}[/tex].

So that,

m<BAM = x + 24

             = 27.5 +24

             = [tex]51.5^{o}[/tex]

m<CTX = x + 11

            = 27.5 + 11

           = [tex]38.5^{o}[/tex]
