Mila [183]3 years ago

Answer:

-24.5 or 7i or -71 (see below)

Step-by-step explanation:

Im gonna guess that you mean (22-16)(2x+49)=0

Therefore, since one of the brackets must be equal to 0 and 22-16 is 6, 2x+49=0 so x is -24.5

However, if you meant (22-16)(x^2+49)=0

then x^2+49=0 so x^2 =-49

Therefore, the answer is complex and therefore 7i or -7i

7 Carolina fosters 5 puppies. For each puppy she buys a crate that costs c dollars
Elena L [17]

2 Answers:

Choice B and Choice C

====================================================

Reasoning:

c = cost of one crate (some unknown amount in dollars)

c+20 = cost of a crate and a leash

5(c+20) = cost of five sets of items mentioned

5(c+20) = 475 is one equation we can form

5c+100 = 475 is another equation we can form

I used the distributive rule to go from 5(c+20) to 5c+100.

The 100 indicates that the five leashes combine to $100, since 5*20 = 100.

The 5c represents the cost of all five crates combined.

So 5c+100 is another way to express the total cost of all five crates and all five leashes.

---------------

Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.

Solve using substitution: y + 2x = -1 and y - 3X = 16
marusya05 [52]

Answer:

Alright i'm just going to assume your doing both of them one at a time.


y + 2x = - 1: So Alright Graph using the slope and y-intercept

Slope: - 2

Y-intercept: - 1

And the other

- 3x = 16: same as well So the Answer to this is Except solve for x by simplifying both sides of the equation, then isolating the variable

Exact form: x = - 16/3

Decimal form: x = - 5.3 Well Hope this helps :)
