7x +33 < 26 isolate the term with a variable by subtracting 33
7x < -7 divide by 7
x < -1
7.) (x, y) —> (1/2*x, 1/2*y)
Answer:
f(x)=(1.023) ⋅ 3^x Growth
f(x)=3 ⋅ (0.072)^x Decay
f(x)=4 ⋅ (0.035)^x Decay
f(x)=2 ⋅ (1.34)^x Growth
Step-by-step explanation:
An exponential function at its heart has a base number of rate. If the rate is less than 1, then the function decays. If the base number or rate is greater than 1, then the function grows and increase.
f(x)=(1.023) ⋅ 3^x Rate 3 - Growth
f(x)=3 ⋅ (0.072)^x Rate 0.072 - Decay
f(x)=4 ⋅ (0.035)^x Rate 0.035 - Decay
f(x)=2 ⋅ (1.34)^x Rate 1.34 - Growth
Answer:
Step-by-step explanation:
To isolate <em>a</em>, we add -3.75 to both sides.
<em>a</em>-(-3.75)=6.11
<em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>
<em>a</em>=6.11<em><u>+(-3.75)</u></em> Simplifying, we get:
<em>a</em>=2.36
