Answer:

x=50

Step-by-step explanation:

x in (-oo:+oo)

(2/5)*x+10 = 30 // - 30

(2/5)*x-30+10 = 0

2/5*x-20 = 0 // + 20

2/5*x = 20 // : 2/5

x = 20/2/5

x = 50

x = 50

Write the absolute value equation given the transformations
Evgesh-ka [11]

Answer:

<em>y = - 0.5 | x - 5 | + 2</em><em> </em>

Step-by-step explanation:

g(x) = |x|

1^{st} step - shifts right 5 units: g(x + 5) = | x <u><em>- 5</em></u> |

2^{nd} step - shifts up 2 units: g(x + 5) + 2 = | x - 5 | <u><em>+ 2</em></u>

3^{rd} step - reflected: - g(x + 5) + 2 =<em> - </em>| x - 5 | + 2

4^{th} step - stretched by 0.5: <em>y = - </em><u><em>0.5</em></u><em> | x - 5 | + 2</em>

<em>y = - 0.5 | x - 5 | + 2</em>

<h3>Total snow fall for three days is 8.75 inches</h3>

<em><u>Solution:</u></em>

Given that,

Snow fell over the past three days

First\ day = 3\frac{2}{4}\ inches = \frac{14}{4}\ inches\\\\Second\ day = 3\frac{2}{4}\ inches = \frac{14}{4}\ inches\\\\Third\ day = 1\frac{3}{4}\ inches = \frac{7}{4}\ inches

<em><u>What was the total snowfall for the three days?</u></em>

Total snowfall = first day + second day + third day

Total\ snowfall = \frac{14}{4} + \frac{14}{4} + \frac{7}{4}\\\\Total\ snowfall = \frac{14 + 14 + 7}{4}\\\\Total\ snowfall = \frac{35}{4} \text{ or } 8.75\ inches

Thus total snow fall for three days is 8.75 inches
