Answer:
x≤1
Step-by-step explanation:
7≥3x+4
Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo. Esto cambia la dirección de la señal.
3x+4≤7
Resta 4 en los dos lados.
3x≤7−4
Resta 4 de 7 para obtener 3.
3x≤3
Divide los dos lados por 3. Dado que 3 es >0, la dirección de desigualdad sigue siendo la misma.
x≤
3
3
Divide 3 entre 3 para obtener 1.
x≤1
Question 1.
The Pythagoras Theorem states that the square of the hypotenuse is equal to the sum of the square of the two legs.

From the question, the hypotenuse is h=10 yd and one of the legs is 2yd.
This implies that,

Evaluate the exponents

Subbtract 4 from each side





The correct answer is C
Question 2
We want to solve

using inverse functions.
The inverse of an exponential function is a logarithmic function.
We take natural log of both sides to get;

Recall that

This means

Logarithm of the base is 1


Divide both sides by 4

Answer:
She will not have enough. She will only have $1480.
Step-by-step explanation:
The formula for simple interest is A=P(1+rt)
A=final amount
P=initial amount
r=interest rate per month
t=time in months
A=1000(1+(0.02)(24))=1480
Rachel will not have enough money after two years (24 months.)
Hope that helps!
