Answer:

x = 4 or x = –4

Step-by-step explanation:

2x² – 17 = 15

Add 17 to both sides:

2x² = 32

Divide both sides by 2:

x² = 16

Take the square root:

√x² = √16

Simplify:

x = ±4

Therefore:

x = 4 or x = –4

BaLLatris [955]

Answer:

The maximum size of the smaller jars is 6 liters

Step-by-step explanation:

Container 1=174 liters of oil

Container 2=258 liters of oil

Same pours the entire content of container one and container 2 into the same number of smaller jars

The maximum size of the smaller jar can be found by finding the highest common factor of 174 and 258

Factors of 174=1,2,3,6,29

Factors of 258=1,2,3,6,43

Common factors of 174 and 258=1,2,3 and 6

Highest common factor=6

Therefore,

The maximum size of the smaller jars is 6 liters

If I receive 3 hour of sick time for every 40 hours I work, and I work 30 hours per week how many hours of sick time do I receiv

mamaluj [8]

Answer:

The total number of hours of sick time you will receive per year=117 hours

Step-by-step explanation:

The total number of sick hours I receive can be expressed as follows;

T=S×N

where;

T=Total number of sick hours

S=number of sick hours per 40 hours of work

N=total number of work works

In our case;

T=unknown

S=(3/40) hours

N=number of hours per week×number of weeks in a year=(30×52)=1,560 weeks

replacing in the expression below;

Total number of sick hours(T)=number of sick hours per 40 hours of work(S)×total number of work works(N)

T=(3/40)×1,560

T=117

The total number of hours of sick time you will receive per year=117 hours

What is the slope of AB when A is (–3, 4) and B is (0, –2)?

Naily [24]

Answer:

- 2/3 is the slope

Step-by-step explanation:

slope = rise/run

Change in y's / Change in x's

(-3,4) (0,2)

y2 - y 1 = 4 - 2

over

x2 - x1 = -3 - 0

slope = 4-2/-3-0

slope = -2/3
