F(x)=x^2-2x-7 given the polynomial function find f(-5)

UkoKoshka [18]

Answer:

f(-5)=28

Step-by-step explanation:

f(x)=x²-2x-7

f(-5) means that we have to replace x by -5.

f(-5)=(-5)²-2(-5)-7=25+10-7=25+3=28

1. Jamie purchases gifts for three friends. She chooses a book for $12.80 and then finds two identical necklaces. Her budget is

Evgen [1.6K]

Step-by-step explanation:

(48 - 12.80)/2 = $17.6

250/6 ≈ 42 and more

485 - 319 = 166 more people

14.5x + 80 > 500
14.5x > 420
x > 420/14.5
x > 29

1.25x + 3 ≤ 28
1.25x ≤ 25
x ≤ 25/1.25
x ≤ 20 miles

6. This seems a typo... 460 is likely $60

60x + 145 ≤ 625
60x ≤ 625 - 145
60x ≤ 480
x ≤ 480/60
x ≤ 8 days

22. One kilometer is approximately 0.62 mile. What fraction represents this length?

bixtya [17]

Answer:

One kilometer is $\frac{31}{50}$ miles

Explanation:

To convert a decimal to a fraction:

1- Write the decimal as a fraction whose denominator is 1

2- Multiply both numerator and denominator by multiples of 10 to eliminate the decimal point

3- Simplify the fraction you have

Now, for the given problem:

The given decimal is 0.62, following the above steps:

Step 1:

$0.62 = \frac{0.62}{1}$

Step 2:

We have two digits after the decimal point, so to eliminate the decimal point, we will multiply the numerator and the denominator by 100

$0.62 = \frac{0.62}{1} * \frac{100}{100} = \frac{62}{100}$

Step 3:

We can note that, in the fraction obtained from step 2, both the numerator and the denominator are divisible by 2, so we simplify as follows:

$\frac{62}{100} = \frac{62/2}{100/2} =\frac{31}{50}$

Hope this helps :)
