If you are only given slope intercept how would u sketch the line ?

Answers

Answer 1

Answer: If you're only given the slope you can't graph the line on an x and y axis because there are no intercepts. But if you are given slope intercept equation, y=mx+b, b is the y intercept and then you find and plot that and then m is the slope and find another point on the line and draw a line through those two points and that is the graphed line.

If f(x) varies directly with x and f(x) = 2 when x = 10, then what is the value of f(x) when x = 40?a.8
b.45
c.200
d.320

Answers

Answer: a.8

Step-by-step explanation:

Given : If f(x) varies directly with x and f(x) = 2 when x = 10

We know if two quantities (x and f(x)) are directly proportional then

$(x_1)/(f(x_1))=(x_2)/(f(x_2))$

Now, for the given problem we have ,

$(10)/(2)=(40)/(f(40))\n\n\Rightarrow\ f(40)=(40*2)/(10)\n\n\Rightarrow\ f(40)=8$

Hence, if x = 40, then f(x)=8.

this is simple multiplication
do 2*4 and 10*4
so you get f(x)=8 and x=40

if you wanna do it by doing division do
2=10
f(x)=40
cross multiply then divide
so do 2*40 to get 80
then do 80/10 to get 8

The revenue, in dollars, of a company that produces jeans can be modeled by 2x2 + 17x – 175. The cost, in dollars, of producing the jeans can be modeled by 2x2 – 3x – 125. The number of pairs of jeans that have been sold is represented by x. The profit is the difference between the revenue and the cost, 20x – 50.If 75 pairs are sold, what's the company's profit?

A farm yard contains some pigs and some chickens. Altogether there are 60 heads and 200 legs. How many pigs are there in the yard?

Answers

Answer:

40 pigs.

Step-by-step explanation:

p=pigs c=chickens.

4p=pigs have 4 legs.

2c=chickens have 2 legs.

4p+2c=200

p+c=60

Do the elimination method:

4p+2c=200

(-4)p+c=60

4p+2c=200

-4p-4c=-240

-2c=-40

c=20

p+20=60

p=60-20

p=40

Hope this helps!
