Answer:

B. 3(a + 7) + 3/(a + 2)

Step-by-step explanation:

Just substitute (a+2) in for every (x) in the equation:

f(a + 2) = 3 ((a + 2) + 5) + 4/(a+2)

           = 3 (a + 7) + 4/(a+2)

[tex]x + x +8 = 46 \\ 2x = 46 - 8 \\ x = 48 \div 2 \\ x = 24[/tex]

Answer:

The function is [tex]y = 40x + 350[/tex]

When he sold 30 cellphones, he earned $1550.

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope(how much y changes when x changes by 1), and b is the y-intercept, that is, the value of w when x = 0.

Base salary of $350 each month and earns an additional $40 for each cellphone he sells.

If he sells 0 cellphones, he earns $350, so [tex]b = 350[/tex].

For each cellphone he sells, he earns $40, so [tex]m = 40[/tex]

The function is:

[tex]y = mx + b = 40x + 350[/tex]

Tomas' earnings for a month where he sold 30 cellphones.

This is y when [tex]x = 30[/tex]. So

[tex]y = 40*30 + 350 = 1550[/tex]

When he sold 30 cellphones, he earned $1550.

Answer:

$18

Step-by-step explanation:

Since there was a 20% discount all we have to do is add 20% to the sale price.

15 increase 20% =

15 × (1 + 20%) = 15 × (1 + 0.2) = 18

Answer:

The point on the Y goes at the end of the equation. The dimensions of the point on the Y is the slope. So Y=2/3x+6

Hope this helps! :)

Answer:

y = 10x + 5

Step-by-step explanation:

Remember when x = 0 that is when you get your y-intercept. So when you look at the chart you  can see that your answer has to have a +5 so now you are  down to only to answers.

Now slope is the change of Y over the change of X , so 5 to 55 is 50

and 0 to 5 is 5

[tex]\frac{y}{x}[/tex]=[tex]\frac{50}{5}[/tex] and that equals 10

put both parts together and

y = 10x + 5

Answer:

Step-by-step explanation:

In x-y coordinates, the direction is 70° CCW from 90° (north), so is 160° from the +x axis. In 4 hours at 18 Nm/h, the ship will travel 4×18 Nm = 72 Nm.

The coordinates in the x-y plane can be found to be ...

  72(cos(160°), sin(160°)) ≈ (-67.7, 24.6)

The ship traveled 67.7 nautical miles west and 24.6 nautical miles north from the port.

Answer:

let required no be x

[tex] \frac{1}{7} = \frac{x}{42} [/tex]

by doing crisscrossed multiplication

[tex]42 \times 1 = 7 \times x[/tex]

42=7x

dividing both side by 7

[tex] \frac{42}{7} = 7x \div 7[/tex]

6=x

therefore x=6

therefore value of remaining no.is 6

Step-by-step explanation:

solution

here,

let, the required number be x

1/7=x/42

or, 42= 7x

or, x= 42/ 7

therefore, x= 6

Answer:

C= 18.85 if you want circumference, A= 28.27 if you want area.

Step-by-step explanation:

For circumference, you would want to multiply the radius with pi (pi x 3.14). The formula for it that you could keep in mind is, "C = 2 pi r" For area, the formula of the circle is, "A = pi r^2" or "Area equals pi r squared"

The circumference of a circle with a radius of 3 inches is 18.84 inches.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

We have to find the  circumference of a circle with a radius of 3 inches.

The formula for circumference of circle is 2πr

Where r is the radius of the circle.

Given radius is 3 inches

Circumference=2π(3)

=6π

The value of π is 3.14

=6×3.14

=18.84 inches

Hence, the circumference of a circle with a radius of 3 inches is 18.84 inches.

d) n = [tex]\frac{s-6}{4}[/tex]

Step-by-step explanation:

This type of graph is called a segment.

To write the solution set which represents the graph

of a segment, read the segment from left to right.

If you take a look at the segment shown here, we would start with the endpoint on the left which is a -4, our variable x would be in the middle, and we would finish things off with the endpoint on the right, which is 5.

Since we have an open dot at -4, we use a less than sign between the -4 and the x and since we have a closed dot at 5, we use a less tan or equal to sign between the x and the 5.

It's important to understand that when representing a segment by reading it from left to right, you will only use "less than" or "less than or equal to" between the parts, never "greater than" or "greater than or equal to."

So the solution for this graph is read {x: -4 < x ≤ 5}.
