Use the definition of absolute value.

• If 4x + 3 ≥ 0, then

|4x + 3| = 15

4x + 3 = 15

4x = 12

x = 3

• Otherwise, if 4x + 3 < 0, then

|4x + 3| = 15

-(4x + 3) = 15

4x + 3 = -15

4x = -18

x = -9/2

Then the solutions are {-9/2, 3}.

The length of a rectangle is twice the width. The perimeter is 48 inches
balu736 [363]

Answer:

x=16;y=8

Step-by-step explanation:

x=length

y=width

the length of a rectangle is twice the width

so,

x=2y........(1)

the perimeter is 48 inches

so,

2(x+y)=48

x+y=24....(2)

2y+y=24        [from 1]

y=8........(2)

so

x=2.8        [from 1 &2]

x=16

Chisaka has less than 145kg of food remaining in her spaceship. She needs a constant amount of food each day that she spacewalks
Veseljchak [2.6K]
If Chisaka does not space walks, the days she spend spacewalking are equal to zero. Since <span>S represents the number of days Chisaka spacewalks, we just need to replace </span>S=0 in our inequality to find how long her food will last if she does not spacewalks:
2.22S+1.3N\ \textless \ 145
2.22(0)+1.3N\ \textless \ 145
1.3N\ \textless \ 145

From this calculation we can infer that the coefficient of N, 1.3, is the amount of food she needs per day if she doesn't spacewalks. Similarly the coefficient of S, 2.2, is the amount of food she need per day if she spacewalks.

We can conclude that Chisaka will need 1.3 kg of food if she doesn't spacewalks, and 2.2 kg of food if she spacewalks.

Math Help please!
ivolga24 [154]
<span>I believe you MEANT 8/(x^2-25)+9/(x-5)  Parentheses in this format are important...the way you typed it means (8/x^2)-25+(9/x)-5 which I doubt you mean. Anyway.

If you factor the first denominator you will see that it is equal to (x+5)(x-5). Division by zero has no meaning so x cannot equal -5 or 5.

If we multiply the second fraction by (x+5) we will have a common denominator of (x^2-25) for the entire equation leaving us with:

(8+9x+45)/(x^2-25)

(9x+53)/(x^2-25)

The second problem is worked in exactly the same way, notice that there is no "solution" as there is no equal sign.  This is an "expression" not an "equation".</span>
