4^{2x}=7^{x-1}\\
16^x=7^x\cdot7^{-1}\\
\dfrac{16^x}{7^x}=\dfrac{1}{7}\\
\left(\dfrac{16}{7}\right)^x=\dfrac{1}{7}\\
x=\log_{\tfrac{16}{7}}\dfrac{1}{7}\approx-2.35389

Point p is the midpoint of de dp 6x+4 and de = 14x -10
vfiekz [6]

Answer:

x = 9

Step-by-step explanation:

A midpoint is found by adding up two numbers and then dividing by 2 (Also known as an average). Therefore, a midpoint marks half of a line. That means that DP is 1/2 of DE. We can now form an equation. 6x + 4 = 1/2 * (14x - 10), making 6x + 4 = 7x - 5 by using the distributive property. Next, isolate x by subtracting by 6x on both sides and adding by 5 on both sides. You would get x = 5 + 4, which means that x = 9.

Mason's annual income is $42,500. He receives an increase of 3.5% every year
Marysya12 [62]

The function that models Mason's yearly income is 42,500(1  + 0.035)^x.

Mason's income after 5 years would be $48,084.85.

<h3>What would be Mason's income after 5 years?</h3>

The function that models Mason's income is an exponential function that has the form:

p(1 + r)^x

Where:

  • r = percentage increase
  • x = number of years
  • p = present income

42,500(1  + 0.035)^x

Income after 5 years: 42,500(1  + 0.025)^5 = $48,084.85
