Step-by-step explanation:

multiple 3a x 3a u wud get 9a to the power 2

-2 x -2 u wud get = 4

then combine the two and write the answer

Answer:

9a² - 12a + 4

Step-by-step explanation:

Given

(3a - 2)(3a - 2)

Each term in the second factor is multiplied by each term in the first factor, that is

3a(3a - 2) - 2(3a - 2) ← distribute both parenthesis

= 9a² - 6a - 6a + 4 ← collect like terms

= 9a² - 12a + 4

John will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.96 and costs an additional $0.12 per mile driven.
The second plan has an initial fee of $47.96 and costs an additional $0.16 per mile driven. How many miles would John need to drive for the two plans to cost
the same?
II miles
Х
?

Answers

So for starts we can go 0.16 x 63 miles = 10.04 so the total for the second plan would be $58 with driving 63 miles. and for the first plan would be 0.12 divided by 3 would be 0.04 so we add them together and we get $58 with driving a 3rd of a mile.

Overall:

1st plan: $58 with driving a 3rd of a mile.

2nd plan: $58 with driving 63 miles.

2 Hiroaki says that a constant of proportionality must be a whole number and

cannot be a fraction or a decimal. Explain why Hiroaki is incorrect.

Answers

Given:

Hiroaki says that a constant of proportionality must be a whole number and  cannot be a fraction or a decimal.

To find:

The explanation, why Hiroaki is incorrect.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

where, k is the constant of proportionality.

It means, the constant of proportionality is the ratio of two directly proportional variables.

So, constant of proportionality can be any real.

Thus, the statement that a constant of proportionality must be a whole number and  cannot be a fraction or a decimal is incorrect.

Hence, Hiroaki is incorrect because constant of proportionality can be any real.

Write an equation of the parabola in vertex from y=a(x-h)^2 +k that passes through (-7,-15) and has vertex (-5,9).

Answers

Answer:

Step-by-step explanation:

We have the work form of the equation, and we also have values for x, y, h, and k. All we need to do is fill those in and solve for a:

[tex]-15=a(-7-(-5))^2+9[/tex]

Let's clean that up a bit.

[tex]-15=a(-2)^2+9[/tex] and

-15 = 4a + 9 and

-24 = 4a so

a = -6

Now we'll fill in the a value along with the h and k to get

[tex]y=-6(x+5)^2+9[/tex] which is choice C

3(2x-4)+6=30

x=___

Answers

Answer:

x = 6

Step-by-step explanation:

Use distributive property: a(b + c) = a*b + a*c

3(2x - 4) + 6= 30

3*2x - 3*4 + 6 = 30

6x - 12 + 6 = 30

6x - 6 = 30

     6x = 30+ 6

     6x = 36

       x = 36/6

x = 6

Answer:

x = 6

Step-by-step explanation:

Simplify 3(2x-4) first: 3 (2x) 3(-4) =

6x - 12+6 = 30

Combine like terms: -12 + 6 = -6

6x - 6 = 30

Add 6 to both sides: 6x = 36

Divide both sides by 6: x = 6

CHECK:

3( 2(6) - 4) +6 = 30

3 (12-4) +6 = 30

3(8) +6 = 30

24+ 6 = 30

30 = 30

Help me to do this problem System by sustitution.
4) y = -3x - 7
-6x - 2y = 14​

Answers

Answer:

The system of equations has infinite solutions

Step-by-step explanation:

∵ y = -3x - 7 ⇒ (1)

∵ -6x - 2y = 14 ⇒ (2)

→ Substitute y in equation (2) by equation (1)

∴ -6x - 2(-3x - 7) = 14

→ Simplify the left side

∵ -6x - 2(-3x) - 2(-7) = 14

∴ -6x + 6x + 14 = 14

→ Add the like terms in the left side

∵ (-6x + 6x) + 14 = 14

∴ 0 + 14 = 14

∴ 14 = 14

∵ The variable is disappeared and the two sides of the equation equal

∴ The equation has many solutions

→ That means x and y can be any numbers

∴ The system of equations has infinite solutions
