Answer:

its either b or d

Answer:

11. A) 12

12. D)11

Step-by-step explanation:

11. We substitute x with 12 in 3(x)-11.

3(12)-11=

36-11= 25

We substitute x with 12 for the second equation (x+13).

12+13=25

Both answers match so the answer for #11 is 12.

12.We substitute x with 11 in 4(x)-4.

4(11)-4=

44-4=40

We substitute x with 11 for the second equation (2(x)+18)

2(11)+18=

22+18=40

Both answers match so the answer for #12 is 11.

Step-by-step explanation:

The expression [tex]\frac{x+3}{3+x}[/tex] is reduced to 1 and the expression [tex]\frac{3-x}{x-3}[/tex] is reduced to -1.

The two given expressions are [tex]\frac{x+3}{3+x}[/tex] and [tex]\frac{3-x}{x-3}[/tex].

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Here,

[tex]\frac{x+3}{3+x}=\frac{x+3}{x+3}=1[/tex]

Now, [tex]\frac{3-x}{x-3}=\frac{-(x-3)}{x-3}=-1[/tex]

Therefore, the expression [tex]\frac{x+3}{3+x}[/tex] is reduced to 1 and the expression [tex]\frac{3-x}{x-3}[/tex] is reduced to -1.

Answer:

y<-4/3x+5

Step-by-step explanation:

the two points that are high lighted are (3,1) and (0,5)

the slope is -4/3

and the point where the line intersects with the y-axis is (0,5) so the y-intercept is 5

so the line is y=-4/3x+5

now you need to determine the inequality

since the line is dotted then it is less than or greater than

as you can see by the line all of the y values on the y-axis, starting from the line that we made, are all less than the line or less than 5

Answer:

It's the first option 5%

Step-by-step explanation:

The probability of a premature baby girl being born at this hospital is,

⇒ 5%

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Now, If the likelihood of boys being born is 56%,

Then, the complement of that is the likelihood of girls being born which is,

⇒ 100% - 56% = 44%.

Since, we are given that of the baby girls born, 12% are premature, the probability of a premature baby girl  being born is:

⇒ (0.44)(0.12)

= 0.0528

⇒ 5.28%

Thus, The probability of a premature baby girl being born at this hospital is,

⇒ 5%

Answer: The amount raised by Ariana in the first two weeks =$480

Step-by-step explanation:

Given: The first week she raises 30% of $600 .

The second week she raises 50% of the $600.

Amount raised in the first week = 50% of $600

= 0.50 x 600

= $ 300

Amount raised in the second week = 30% of $600

=0.30 x 600

= $180

The amount raised by Ariana in the first two weeks = $300+$180

= $480

Hence, The amount raised by Ariana in the first two weeks =$480

Answer:

$6n will represent the total revenue made from selling n tickets at $6 per ticket

Step-by-step explanation:

Here, we want to get what 6n means in the given context

Mathematically when calculating profit, we have to subtract the cost from the revenue

The revenue refers to the money made ;

From the question, $6 tickets were sold to a total of n people

The money made from these sales will be the product of the cost of each ticket by the number of people who bought the ticket

That will be $6 * n = $6n

Answer:

y = 2x + 2

Step-by-step explanation:

y = mx+c

m = slope

c =y -intercept

Therefore, the required equation is:

y = 2x + c

Putting the point (0,4) in it as it lies on a line, we get:

4 = 2 + c

Therefore:

c = 2

So, y = 2x + 2

Brainlist pls!

The equation of a line that passes through the point (0,4) and has a gradient of 2 is y = 2x + 4

The equation of a line in point-slope form is expressed as:

y = y1 = m(x-x1)

Given the following

Slope m = 2

(x1, y1) = (0, 4)

Substitute

y - 4 = 2(x- 0)

y -4 = 2x

y = 2x + 4

Hence the equation of a line that passes through the point (0,4) and has a gradient of 2 is y = 2x + 4

Answer: 1/3

Step-by-step explanation: slope is the difference between the y values over the difference of the x values

The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope could be positive or negative.

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

Slope m = (-4 + 5)/(3 - 0)

m = 1/3

Hence "The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3".

Answer:

Cassava = ⅓ or 33.333%

Maize = ⅔x⅔ = 44.444%

total so far =77.777%

Remaining vegetable area =(100–77.777%) = 22.222%

If remaining area vegetables = 22.222% = 10 acres

Maize = ⅔x⅔ = 44.444% or 20 acres

Cassava = ⅓ or 33.333% or 15 acres

Total land area = 45 acres.

Answer:

88:56 = 11:7

Step-by-step explanation:

Step One

Add the two ratios together 11 + 7 = 18

Now set up a ratio to solve for 11 parts out of 18

11:18 = x:144         Proportion

11 / 18 = x / 144    Equation: Cross mulitiply

11*144 = 18x         Combine the left side

1584   = 18x         Divide by 18

1584 / 18  = x

88 = x

That is the larger amount (11 is larger than 7)

Find the smaller amount

144 - 88 = 56

The two amounts are in the ratio of 11:7

88:56 = 11:7
