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 farmer sells 8.9 kilograms of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. H

aleksandrvk [35]

Answer: 2.225 kg

Step-by-step explanation:

You know that:

- The total weight the farmer sold was 8.9 kilograms.

- 3/4 of this weight is apples, and the rest is pears.

Therefore, to calculate the amount of kilograms of pears she sold at the farmer's market (which you can call x), you need to apply the following proccedure.

Thefore, you obtain the following result:

$x=8.9kg-(8.9kg*\frac{3}{4})\\x=2.225kg$

soymeal is 14 percent protein cornmeal is 7 percent protein how many pounds of each should be mixed together in order to get 280

erma4kov [3.2K]

Let the weight of soymeal be s, and let the weight of cornmeal be c.
You need a total of 280 lb, so that gives us one equation.

s + c = 280

Now we use the protein to write another equation.
The protein in s lb of soymeal is 0.14s.
The protein in c lb of cornmeal is 0.07c.
The protein in 280 lb of 0.09% protein mix is 0.09(280).
This gives us a second equation.

0.14s + 0.07c = 0.09(280)

Now we solve the two equations as a system of equations.

s + c = 280
0.14s + 0.07c = 0.09(280)

Solve the first equation for s and plug in tot eh second equation.

s = 280 - c

0.14(280 - c) + 0.07c = 25.2

39.2 - 0.14c + 0.07c = 25.2

-0.07c = -14

c = 200

Now we substitute c = 200 in the first equation to find s.

s + 200 = 280

s = 80

Answer: 200 lb of soymeal and 80 lb of cornmeal

Please help this is important -1.5x+12=2.5x-12

Anna35 [415]

Answer:

x = 6

Step-by-step explanation:

move all terms to the left:

-1.5x+12-(2.5x-12)=0

get rid of parentheses

-1.5x-2.5x+12+12=0

add all the numbers together, and all the variable.

-4x+24=0

move all terms containing x to the left, all other terms to the right

-4x=-24

x=-24/-4 - divide

x=+6
