Answer:

4(2x - 3) is how I would write it algebraically.

Step-by-step explanation:

The number is x, as it is unknown. 2x means you multiply the unknown number by 2.

2x

Now, you subtract 3.

2x - 3

And then you multiply the result of that by 4, hence the parentheses.

4(2x - 3)

To solve, just distribute 4. 4*2x = 8x. 4*-3 = -12.

8x - 12

Answer:

8x-12

Step-by-step explanation:

(2x-3)* 4 = 8x-12

The equation of the line that a slope of 6 and a y-intercept of -9 will be y = 6x - 9.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The equation of the line that a slope of 6 and a y-intercept of -9 will be

The equation of the line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

Then we have

m = 6 and c = - 9

Then the equation of the line will be

y = 6x - 9

Answer: 3

Step-by-step explanation:

Vince will have to buy three cartons of 500 ml each.

An expression in mathematics is a combination of terms both constants and variables.

Given is that every time Vince orders Chinese food, he gets egg drop soup. So, he decides to learn how to make it himself. His recipe calls for 1.5 liters of broth, but he can only find 500 milliliter cartons at the store.

We know that -

1 Liter = 1000 milliliters

1.5 liter = 1500 liters

Now -

1 carton 500 ml.

Then, 1 ml will be in (1/500) carton.

So, 1500 ml will be in (1/500 x 1500) = 3 cartons

Therefore, Vince will have to buy three cartons of 500 ml each.

Answer:

y = 1/2x + 5

Step-by-step explanation:

The formula for an equation is y = mx + b

m is the slope. It is given

y = 1/2x + b

b is the y-intercept

In this case, we must substitute to find the y-intercept

We are given coordinate pair (4,7)

Plug our pair in and we get => 7 = 1/2(4) + b

=> 7 = 2 + b

easily, we find b = 5

We get our equation: y = 1/2x + 5

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

log₃[1 + log₃(2ˣ - 7)] = 1

log₃[1 + log₃(2ˣ - 7)] = log₃(3)

1 + log₃(2ˣ - 7) = 3

log₃(2ˣ - 7) = 2

log₃(2ˣ - 7) = log₃(3)²

2ˣ - 7 = 9

2ˣ = 9 + 7

2ˣ = 16

2ˣ = 2⁴

x = 4

By putting x = 4 in the original equation,

log₃[1 + log₃(2⁴ - 7)] = 1

log₃[1 + log₃(16 - 7)] = 1

log₃[1 + log₃(9)] = 1

log₃[1 + log₃(3)²] = 1

log₃[1 + 2] = 1

log₃[3] = 1

1 = 1

Therefore, x = 4 is not the extraneous solution and there is no error in your answer.

Answer:

Figure P'Q'R'S' has been dilated by a scale factor = 1.5 to form image quadrilateral P"Q"R"S".

Step-by-step explanation:

From the graph attached,

Coordinates of point T' → (2, -2)

Coordinates of point T'' → (3, -3)

As it's clear form the picture, quadrilateral P'Q'R'S' has been dilated to form the image quadrilateral P"Q"R"S" by a scale factor = k

By the rule,

T'(x, y) → T"(kx, ky)

Therefore, T'(2, -2) → T"(2k, -2k)

T"(2k, -2k) → T"(3, -3)

By comparing x-coordinates,

2k = 3

k = [tex]\frac{3}{2}[/tex]

k = 1.5

Therefore, figure P'Q'R'S' has been dilated by a scale factor = 1.5 to form quadrilateral P"Q"R"S".

Answer:

Hence doubling the dimension gives a volume greater than doubling the original volume.

Step-by-step explanation:

Given The dimension :

Original dimension : 6 meters by 5 meters by 12 meters

Volume of original dimension :

6 * 5 * 12 = 360 m³

If dimension is doubled :

2 * 6 = 12

2 * 5 = 10

2 * 12 = 24

Volume = (12 * 10 * 24) = 2880 m³

2 * original volume = 2 * 360 = 720 m³

Hence doubling the dimension gives a volume greater than doubling the original volume.

Answer: (-5, 2). Please mark me brainliest

Step-by-step explanation: So we are finding the coordinates of point A first we have to mark the x-coordinate (-5) so we have to look at the horizontal line (x-coordinate) and the A is an -5 so the first part should be -5 next we have to do the vertical line (y-coordinate) and it is on the 2 so 2 so the answer is (-5,2).

Answer:

See Explanation

Step-by-step explanation:

Given

(1) CALL and (2) BARK

Required

Why is the number of arrangement of (1) less than (2)

The reason is that in (1), letter L occurred twice. When there is a repetition of letters, the number of ways of arrangement reduces

For (1)

There are 4 letters and L is repeated twice.

[tex]Arrangement = \frac{4!}{2!}[/tex]

[tex]Arrangement = \frac{24}{2}[/tex]

[tex]Arrangement = 12[/tex]

For (2)

There are 4 letters and no repetition

[tex]Arrangement = 4![/tex]

[tex]Arrangement = 24[/tex]

The reason why the number of ways of CALL is less than the number of ways of arranging the letters of BARK should be explained below.

The reason should be that in (1), letter L occurred twice. At the time When there is a repetition of letters, the number of ways of arrangement decreases.

So here arrangement be like

When there is 4 letters and L is repeated twice.

=4!/2!

= 24/2

= 12

And,

When there is 4 letters and no repetition

= 4!

= 24

There are 8 girls

Step-by-step explanation:

We see that right now there are 6 more boys than girls and if there were 2 girls there would be 14 boys meaning there would be 12 more boys than girls if you continue in this pattern you would get-

7:1= 6 more boys                   35:5=30 more boys                                                

14:2= 12 more boys                42:6= 36 more boys

21:3=18 more boys                 49:7= 42 more boys

28:4= 24 more boys               56:8= 48 more

This shows us that if there are 8 girls in  group there are 56 boys meaning there are 48 more boys than girls if the group had 8 girls

Answer:

does not represent a linear function.

Step-by-step explanation:

For the function to be linear, the slope must be the same for every poknt along the function. If is not, then is not a linear function.

Let us now calculate the slope;

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

We shall take the first two points

[tex]m = \frac{4 - 2}{2 - 1} \\ m = \frac{2}{1} \\ m = 2[/tex]

Next we shall take the 2nd and 3rd points

[tex]m = \frac{8 - 4}{3 - 2} \\ m = \frac{4}{1} \\ m = 4[/tex]

The slope is not the same for these two different point, hence this table does not represent a linear function.

Sum of the opposite pair of a cyclic quadrilateral is 180°.

c= 180-102= 78°

c= 180-102= 78°d= 180-92= 88°

 intercepted arc

=>2(102°)= 140+a°

a=64°

Answer:

C  None of the above

Step-by-step explanation:

Here are the required options

Choose all answers that apply

A  (5g+3h).8  

B  (5g+3h).6  

C  None of the above

Given the expression;

(5g+3h+4).2

Expand

(5g+3h+4).2

= 2(5g+3h+4)

= 2(5g) + 2(3h) + 2(4)

= 10g+6h+8

Checking option A;

(5g+3h).8

Expand

= 8(5g+3h)

= 8(5g) + 8(3h)

= 40g+24h

Checking option B:

(5g+3h).6

Expand

= 6(5g+3h)

Using the distributive law;

= 6(5g) + 6(3h)

= 30g+18h

Since none of the expressions for A and B is equivalent to 10g+6h+8, hence NONE of the options are correct
