If √6x

Mathematics
1 answer:
weeeeeb [17]3 years ago
4 0

Answer:

B) 15

Step-by-step explanation:

sqrt(6x) = 3 sqrt(10)

Square each side

(sqrt(6x))^2 = (3 sqrt(10))^2

Remember (ab)^2 = a^2 b^2

6x = (3^2) sqrt(10))^2

6x = 9 * 10

6x = 90

Divide each side by 6

6x/6 = 90/6

x = 15

3x -15x - 30 > 54

-12x-30>54

-12x<54+30    

I moved 30 from left side to right which becomes positive and > becomes <

A medical clinic is reducing the number of incoming patients by giving vaccines before flu season. During week 5 of flu season,
8_murik_8 [283]

Answer:

f(x) = -6x +120

Step-by-step explanation:

Let's call y the number of patients treated each week

Let's call x the week number.

If the reduction in the number of patients each week is linear then the equation that models this situation will have the following form:

y = mx + b

Where m is the slope of the equation and b is the intercept with the x-axis.

If we know two points on the line then we can find the values of m and b.

We know that During week 5 of flu season, the clinic saw 90 patients, then we have the point:

(5, 90)

We know that In week 10 of flu season, the clinic saw 60 patients, then we have the point:

(10, 60).

Then we can find m and b using the followings formulas:

m=\frac{y_2-y_1}{x_2-x_1}   and b=y_1-mx_1

In this case: (x_1, y_1) = (5, 90) and (x_2, y_2) = (10, 60)

Then:

m=\frac{60-90}{10-5}

m=-6

And

b=90-(-6)(5)

b=120

Finally the function that shows the number of patients seen each week at the clinic is:

f(x) = -6x +120

Solve each absolute value equation and chose The correct answer from the choices provided |x|+5=18
Kamila [148]

Solve the absolute value equation.

First subtract 5 from both sides.

|x|+5=18

|x|=13

If the absolute value of x is 13 that x equals 13 and -13. Absolute value means distance from 0.

x=13,-13
