Let a be the number of trumpet players
Let b be the number of saxophone players
---------------------
(1) a = b-10
(2) b =3a
----------------
Substitute
(2) into (1)
(1) a =3a-10
(1) 2a =10 

 (1) a = 5and
(2) b = 3(5)(2)
b =  15
------------------
There are 5 trumpet players and 15 saxophone player

The rent for an apartment is represented by R(a) = 2.00a + 50.00, where a is the area of the apartment in square feet. The rent
QveST [7]

Answer:

<em>The correct option is:  D)  S(a) = 2.00a + 100.00; shift 50 units up</em>

Step-by-step explanation:

The rent for an apartment is represented by  R(a) = 2.00a + 50.00

Now, the rent increases by $50.00 when the apartment is furnished. So, the rent of a furnished apartment will be:  (2.00a+50.00+50.00) = (2.00a+100.00) dollar

Thus the new function will be:   S(a)= 2.00a+100.00

<u>As the output of the original function is increased by 50.00, so the graph of the original function will shift 50 units upward</u>.

Greg earns $14 per hour at his office job, along with a $25 weekly bonus. The following inequality represents his earnings on hi
Neporo4naja [7]

Answer:

Greg worked more than 20 hours.

Step-by-step explanation:

Let's solve the inequality for h so we know how many hours Greg worked:

Step 1. Subtract 25 from both sides of the inequality

14h+25>305

14h+25-25>305-25

14h>280

Step 2. Divide both sides by 14

\frac{14h}{14} >\frac{280}{14}

h>20

We can conclude that Greg worked more than 20 hours.

Average Temperatures Suppose the temperature (degrees F) in a river at a point x meters downstream from a factory that is discha
mr Goodwill [35]

Answer:

Step-by-step explanation:

Average Temperatures Suppose the temperature (degrees F) in a river at a point x meters downstream from a factory that is discharging hot water into the river is given by

T(x) = 160-0.05x^2

a. [0, 10]

For x = 0

T(0) = 160 - 0.05 × 0^2

T(0) = 160

For x = 10

T(10) = 160 - 0.05 × 10^2

T(10) = 160 - 5 = 155

The average temperature

= (160 + 155)/2 = 157.5

b. [10, 40]

For x = 10

T(10) = 160 - 0.05 × 10^2

T(10) = 160 - 5 = 155

For x = 40

T(10) = 160 - 0.05 × 40^2

T(10) = 160 - 80 = 80

The average temperature

= (80 + 155)/2 = 117.5

c. [0, 40]

For x = 0

T(0) = 160 - 0.05 × 0^2

T(0) = 160

For x = 40

T(10) = 160 - 0.05 × 40^2

T(10) = 160 - 80 = 80

The average temperature

= (160 + 80)/2 = 120

The slope-intercept form of the equation of a line that passes through point (-2,-13) is y=5x-3. What is the point-slope form of
marissa [1.9K]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

<h3>Point - slope form of equation: </h3>

        \sf \boxed{\bf y - y_1=m(x-x_1)}

Slope intercept of the line : y =5x - 3

Comparing with y = mx +b , m =slope = 5

m = 5 and Point (-2 ,-13)

     y - [-13] = 5(x - [-2])

     y + 13 = 5(x + 2)
