Shen will donate up to $440 to charity. The money will be divided between two charities: the City Youth Fund and the Educational

natka813 [3]

Answer:

Step-by-step explanation:

Let the amount donated to City Youth Fund = $x

And the amount donated to the Educational Growth Foundation = $y

Amount donated to the Educational Growth Foundation is at least four times the amount donated to City Youth Fund.

y ≥ 4x ------(1)

Total amount she can donate is up to $440

x + y ≤ 440 ------(2)

And the constraints are x ≥ 0 --------(3)

y ≥ 0 ------(4)

And solution set will be the common shaded area of both inequalities as shown in the graph attached.

(By using a graphing tool we can find the graph).

Log7^x-log7^3=1 <br>if anyone can help me with this problem please help me

vagabundo [1.1K]

Log7 (x+3) - log7 (x-3) = 1
log7 [(x+3) / (x-3)] = 1
raise both sides to power of 7
(x+3) / (x-3) = 7
7x – 21 = x + 3
6x = 24
x = 4
