Answer:

Graph is a straight line.

Step-by-step explanation:

We have given a function.

f(x) = 4x+5

We have to graph the function.

Sicce, f(x) = mx+c is equation of line where m is slope and c is y-intercept.

comparing given equation with equation of line, we have

m = 4 and c = 5.

putting f(x) =  in given equation,we have

0 = 4x+5

x = -5/4 hence x-intercept = -5/4 = 1.25

Dram graph and point out the y-intercept and x-intercept.

Graph is attached.Graph is a straight line.

Answer:

Step-by-step explanation:

The 5 is the y intercept. So that point will be (0,5). The 4 in front of the x is the slope. SO from (0,5) you would up up 4 and over 1. This will bring you to (1,9). You can do this in both directions.

A pharmacist has 40% and 60iodine solutions on hand. How many liters of each iodine solutions will be required to produce 4 lite
Schach [20]

A pharmacist has 40% and 80% of iodine solutions on hand. How many liters of each iodine solution will be required to produce 4 liters of a 50% iodine mixture?

.

Let x = liters of 40% iodine

then

4-x = liters of 80% iodine

Using algebra:

.40x + .80(4-x) = .50(4)

.40x + 3.20-.80x = 2

3.20-.40x = 2

x = 4 liters (40% iodine)

80% iodine:

4-x = 4-4 = 0 liters needed (80% iodine)

If the circumference of a circle measures 25.12cm, what is the area of the circle in terms of pi?
kiruha [24]

Answer:

Step-by-step explanation:

The formula for circumfrance is 2*(pi)*R and the formula for area is (pi)* R^2 or (pi) R-squared.

Circumfrance is 25.12 so....

25.12 = 2 * (pi) R........ you want to find R because you need it to find the area

R is about 4; it is 3.99797 .

You use the R that you goot from cirdumfrance to find area.

Area = (pi) (4)^2 = 50. 265

or is you prefer a more precise answer, Area = 50.2145
