Answer:

The graph is attached below

Step-by-step explanation:

$y=\frac{3}{4} x+5$

Complete the table. Plug in some random number for x and find out y

x $y=\frac{3}{4} x+5$

-4 y=-3+5=2

0 y=0+5=5

4 y=3+5=8

Now graph the points we got from the table

(-4,2) (0,5) (4,8)

The graph is attached below

XZ=n, WZ=2x-5, and the perimeter of ΔXWZ is 20. What is the value of n?

Sergio039 [100]

Answer:

Step-by-step explanation:

Since it's an isosceles triangle, WX=WZ= 2n-5

Perimeter = n + (2n-5) + (2n-5)

= 5n - 10

The Perimeter is given to be 20

5n - 10 = 20

5n = 30

n = 6

Write $\frac{99}{100}\cdot(0.\overline{4})$ as a fully simplified fraction.

Oksi-84 [34.3K]

Answer:

$\frac{11}{25}$

Explanation:

The expression that must be rewritten as a fully simplified fraction is:

$\frac{99}{100}\cdot(0.\overline{4})$

You must, first, convert $0.\overline{4}$ as a fraction.

The line over the decimal 4 means that the digit 4 repeats indefinetly.

To find the fraction that represents this number you follow this procedure:

$F=0.\overline 4\\ \\ 10F=4.\overline 4\\ \\ 10F-F=4\\ \\ 9F=4\\ \\ F=4/9$

Now, you can mutiply both fractions:

$\frac{99}{100}.\frac{4}{9}=\frac{99\times 4}{100\times9}=\frac{11}{25}$

the expression -300 + 14y represents a submarine that began at a depth of 300 feet below sea level and ascended at a rate of 14

spayn [35]

Answer:

174 feet below sea level

Step-by-step explanation:

y is the number of minutes so you can multiply 14 by 9

14*9 is 126

then you add 126 to -300

126 + (-300) is essentially 126 - 300 and that is -174

the submarine was at 174 feet below sea level
