Answer 1

Answer:

y=2x-6. ---------(1)

4x-2y=14. --------(2)

substituting equation 2 in 1

4x-2(2x-6)=14

4x-4x+12=14

so it has no solution

© The ratio of boys to girls in a class is 5:4. There are 36 students in the class. How many
students are girls?​

Answers

Answer:

16

Step-by-step explanation:

[tex]no \: of \: girls = \frac{4}{5 + 4} \times 36 \\ \\ = \frac{4}{9} \times 36 \\ \\ = 4 \times 4 \\ \\ = 16[/tex]

Answer:

Step-by-step explanation:

let the ratio of boys and girls be 5x and 4x

According to question,

5x+4x = 36

or, 9x= 36

x=4

number of boys = 5x

                            = 5·4= 20

number of girls = 4x

                         = 4.4=16

therefore the total no of boys is 20 ans girls is 16

the vertices of xyz are x (1,-4)

Answers

Answer:

5. The vertices of ΔX'Y'Z' are (-3, -7), (-6, -4), (-1, -2)

6. The vertices of ΔX'Y'Z' are (6, -7), (3, -4), (8, -2)

Step-by-step explanation:

If the point (x, y) translated by T → (h, k), then its image is (x + h, y + k)

#5

In ΔXYZ

∵ X = (1, -4), Y = (-2, -1), Z = (3, 1)

∵ T → (-4, -3)

h = -4 and k = -3

→ Use the rule above to find the image of the vertices of the Δ

∵ X' = (1 + -4, -4 + -3)

X' = (-3, -7)

∵ Y' = (-2 + -4, -1 + -3)

Y' = (-6, -4)

∵ Z' = (3 + -4, 1 + -3)

Z' = (-1, -2)

The vertices of ΔX'Y'Z' are (-3, -7), (-6, -4), (-1, -2)

#6

In ΔXYZ

∵ X = (1, -4), Y = (-2, -1), Z = (3, 1)

∵ T → (5, -3)

h = 5 and k = -3

→ Use the rule above to find the image of the vertices of the Δ

∵ X' = (1 + 5, -4 + -3)

X' = (6, -7)

∵ Y' = (-2 + 5, -1 + -3)

Y' = (3, -4)

∵ Z' = (3 + 5, 1 + -3)

Z' = (8, -2)

The vertices of ΔX'Y'Z' are (6, -7), (3, -4), (8, -2)

Michael earns $9 per hour. He works 28 hours each week. How much does he earn in 6 weeks?

Answers

Answer:

$1, 512

This is how:

1) Michael works 28 hours in one week. So how many hours does he work in 6 weeks?

So you need to calculate : 28 × 6 = 168

SO THIS IS THE TOTAL NUMBER OF HOURS FOR 6 WEEKS.

2) because Michael gets paid $9 PER HOUR :

You will need to multiply the amount of money he receives with the total number of hours he works.

168 × 9 = $ 1, 512

He earns $1,512 in 6 weeks

Tawanna factored one or both pieces of the expression incorrectly.
Tawanna did not include each factor in the GCF.
Tawanna should have used each common factor once.
Tawanna included only one of the variables in her solution.
Mark this and return

Answers

Answer:

Tawanna should have used each common factor once.

Step-by-step explanation:

Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b.

Factors of 2ab: 1, 2, a, and b

Factors of 8b: 1, 2, 4, 8, and b

GCF: (1) (1) (2) (2) (b) (b)

GCF = Greatest common factor

She has calculated the GCF incorrectly as she should use each common factor once only. But she has taken all the common factors twice which is wrong.

Hence, the error in Tawanna’s solution is that "Tawanna should have used each common factor once.". Hence, the correct option is (c).

Answer:

C - Tawanna should have used each common factor once.

Step-by-step explanation:

For this one, try plugging in 1.

y = 1.1(1)^2 + 4.2(1) - 4.9

1.1 + 4.2 - 4.9

1.1 + 4.2 = 5.3

5.3 - 4.9 = 0.4

0.4 is the closest for (1, 0.3)

So the correct answer is B. All the others don't make sense and are not close enough.

Answers

Tracy = x
Jocelyn = 3x - 80

Solution: Tracy spent $30
If Daniel spent x

Answers

The slope-intercept form: y = mx + b

So we need to "solve" given equation for y

3.3x - 3y = 2.4           {subtracting 3.3x from both sides}

- 3y = 2.4 - 3.3x        {dividing both sides by (-3)}
