f(-2) means replace x in the equation with -2, then solve:

-2^2 +5(-2)

Simplify:

4 + -10

Add:

-6

Why does -6 - (-2) equal -4?
lukranit [14]

Answer:

when you subtract a negative number the two negative signs cancel out and it turns to a positive number

Step-by-step explanation:

in -6 - (-2)

the two - signs cancel out so it ends up being

-6+2 which is why it equals -4

If 4 bags of corn can feed a herd of cows for 6 days, how many bags will feed the herd for 9 days ?
VARVARA [1.3K]
Well, if 6/4 equals 1.5 --

Then 1.5*5, (which is the next quantity of days before it hits 9) equals 7.5.

Hope this helps.

All triangle angles have 60 degree angles. What are the side lengths?
Alex_Xolod [135]
If all the angles are 60 degrees, this is an equilateral triangle. This means that all the sides have the same lengths. Whatever length side a is, b and c have the same length. 

Hope this helps :)

Two lines, C and D, are represented by the equations given below:
lakkis [162]

y=x+14 line 1

y=3x+2 line 2

These are both the equation of lines written in slope intercept form

y=mx+b where m is the slope and the point (0,b) is the y intercept.

The first line has a slope of m=1. The 2nd line has a slope of m=3

Since these lines have different slopes, they are not parallel, thus they will cross at some point. What you have to determine is where the lines cross, which will be a point (x,y) that is on both lines.

We already have y solved in terms of x from either equation so we can use substitution to solve the system.

Since y=x+14 from line 1, put x+14 in place of y in the equation of line 2.

x+14=3x+2

solve for x.

Subtract x from both sides...

14= 3x-x+2

14=2x+2

subtract 2 from both sides

14-2=2x

12=2x

divide both sides by 2

6=x

We now have the x value of the common point. Plug the value 6 in for x in one of the original equations and solve for y.

y=6+14

y=20

These two lines cross at the point (6,20) which is a point the two lines have in common.
