Which of the following expressions is not equivalent to 12x + 18y?

A.
6(2x + 3y)

B.
3(4x + 18y)

C.
6(2x) + 18y

D.
6x + 9y + 6x + 9y

Answer:

y = -3x - 16

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Given: y - 2 = -3(x + 6)

Slope-intercept form: y = mx + b

To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). By looking at the given equation, we can see that the slope is -3. We are also given the value of one point: (-6, 2).

To find the y-intercept, input the given values of the slope and the point into the equation format and solve for b:

y = mx + b

2 = -3(-6) + b

2 = 18 + b

Subtract 18 from both sides of the equation to isolate b:

2 - 18 = 18 - 18 + b

-16 = b

The y-intercept is -16.

Now that we know the slope and the y-intercept, we can write the equation:

y = -3x - 16

Answer:

y=2x-1

Step-by-step explanation:

Gradient : (7-3) / (4-2) = 2

y=2x+c

substitute one of the points

3=2*2+c

c=-1

y=2x-1

Step-by-step explanation:

1. (4m² - 1.5m + 2) + (9m - 2m³ + 2m)

= 4m² - 1.5m + 2 + 9m - 2m³ + 2m

= 4m² + (-1.5m + 9m + 2m) + 2 + 2m³

= 4m² + 9.5m + 2 + 2m³

= 2m³ + 4m² + 9.5m + 2

2. (-3y + 2y² - 6) + (3y + 4y² + x)

= -3y + 2y² - 6 + 3y + 4y² + x

= (-3y + 3y) + (2y² + 4y²) - 6 + x

= 0y + 6y² - 6 + x

= 6y² - 6 + x

Answer:

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = 3

Step-by-step explanation:

Multiply both sides by 3. I take it mean 1/3 * x and not 1/(3*x) which puts x in the denominator.

6x - 15 = (1/3) x * 3             Cancel on the right.

6x - 15 = x                          Subtract 6x from both sides.

6x - 6x - 15 = x - 6x           Collect light terms

- 15 = - 5x                          Divide by - 5

-15/-5 = -5x/-5

x = 3

Answer:

A

Step-by-step explanation:

At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1)  part. This happens for x=1. So you can already rule out answers C and D.

Now fill in x=-2 in both remaining answers and see what happens.

For A: y = -2(-2 - 1)² + 3 = -15

For B: y = (-2 - 1)² + 3 = 12

That eliminates B and leaves A.

The question is incomplete, the complete question is shown in the image attached.

Answer:

Material 1

Step-by-step explanation:

Given the table shown in the complete question, we can see that the weights in material 1 does not have a proportional relationship with length.

If something has a proportional relationship, then it increases or decreases by a constant value called the constant of proportionality. This is not the case in material 1 as seen from the table.

Answer:

Volume = 315 cm³

Step-by-step explanation:

Volume = Length × Width × Height

→ Substitute in the values

Volume = 6 cm × 3.5 cm × 15 cm

→ Simplify

Volume = 315 cm³

Answer:

y=5/4-10

Step-by-step explanation:

Answer:

1. x = 16

2. 2x + 9 = 41

Step-by-step explanation:

So this is the first step.

2x + 9 + 3x + 1 = 90 (collect like terms)

5x + 10 = 90 (subtract 10 on both sides)

5x = 80 (divide by 5 on each side)

x = 16

Plug in to 2x + 9

2(16) + 9 =

32 + 9 =

41 = 2x + 9

Hope this helps! Have a blessed day!

Answer:

A. 15-year mortgage =$141,478.20

30-year mortgage =$187,707.60

B. $46,229.40

Step-by-step explanation:

A. Calculation to Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the​ 30-year mortgage.

Calculation for 15-year mortgage

Cost amount to save for 15-year mortgage=$785.99*15-year*12 months

Cost amount to save for 15-year mortgage =$141,478.20

Calculation for 30-year mortgage

Cost amount to save for 30-year mortgage =$521.41*30-year*12 months

Cost amount to save for 30-year mortgage =$187,707.60

B. Calculation for How much would they save if they selected the​ 15-year mortgage

Using this formula

Amount to save=30-year mortgage -15-year mortgage

Let plug in the formula

Amount to save=$187,707.60-$141,478.20

Amount to save=$46,229.40

Therefore How much would they save if they selected the​ 15-year mortgage will be $46,229.40

Answer:

42

Step-by-step explanation:

[tex]41^{2}[/tex] + [tex]9^{2}[/tex] = [tex]c^{2}[/tex]

So, what's 41 to the power 2?

Thus;

1,681

Do the same for the other one.

9 to the power of 2

Thus;

81

Add all these up all your final answer to get a total of 1,762.

1681+81=1762

Thus;

[tex]c^{2} = 1762[/tex]

Then square root your final answer

[tex]\sqrt[]{1762}[/tex]=[tex]c^{2}[/tex]

Thus;

42= [tex]c^{2}[/tex]

Answer: plane A = 333.33mph

Plane B = 500mph

Step-by-step explanation:

Given data:

Distance between the two planes = 2400miles.

Plane A flew North

Plane B flew south

Solution:

Let v represent plane A.

Let 2v represent plane B.

Distance between the two plane

v + 1.5* v = 3*v

7.5v = 2500miles

v = 333.33mph

Plane B has one and half times the speed of plane A

= 1.5 * 333.33

= 500mph

Answer:

12$ an hour.

Step-by-step explanation:

Simply set it up as fraction in a way set it as  30/2.5 and divide both values by 2.5 which you get 12 from 30 and 1 from 2.5 there's your unit rate. 12/1 or 12$ an hour.

Answer:  17/18

In words, this is seventeen eighteenths

==========================================

Work Shown:

4/9 + 9/18

8/18 + 9/18 ... see note below

(8+9)/18

17/18

----------------

note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.

The diagram below shows a visual representation of why 4/9 = 8/18.

In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.

Answer: its 17/18
