Answer:

Solution of the equation 2|x +7|-3=5 is :

Answer:

  x = -3 and x = -11

Step-by-step explanation:

Find the "bare" absolute value function, then solve the two resulting equations.

  2|x+7| -3 = 5

  2|x +7| = 8 . . . . . add 3

  |x +7| = 4 . . . . . . divide by 2

This resolves to two equations:

  x +7 = 4

  x = -3 . . . . . subtract 7

and

  x +7 = -4

  x = -11 . . . . . subtract 7

The two solutions are ...

  x = -3 and x = -11

A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses
laila [671]

Answer:

Probability of missing two passes in a row is 0.08.

Step-by-step explanation:

Event E = A football player misses twice in a row.

P(E) = ?

Event X = Football player misses the first pass

P(X) = 0.4

Event Y = Football player misses just after he first miss

P(Y) = 0.2

Both the events are exclusive so the probability of occuring of these two events can be calculated by the formula:

P(E) = P(X).P(Y)

P(E) = 0.4*0.2

P(E) = 0.08

3. Jim invests $3500, compounded annually at 12% for 3 years. What is the total
irga5000 [103]

Answer:

None of the above, it should be $4760

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 3500 × 0.12 × 3 = 1260

I = $ 1,260.00

The simple interest accumulated

on a principal of $ 3,500.00

at a rate of 12% per year

for 3 years is $ 1,260.00

Rewrite: 72x3/4<br> please show how you got answer
Alex_Xolod [135]

We have been given the expression

72 \times \frac{3}{4}

We can rewrite the expression as \frac{72\times 3}{4}

In order to simplify the given expression, we can check if we have any common terms in the numerator and denominator.

We can write the term 72 which is in the numerator as 18\times 4

Thus, the expression becomes

\frac{18\times 4\times 3}{4}

We can see that 4 is common in both numerator and denominator. Hence, we can cancel 4. Thus, we are left with

18 \times 3\\&#10;=54

Therefore, we can rewrite the given expression as 54.
