we know that
if the exponential function passes through the given point, then the point must satisfy the equation of the exponential function
we proceed to verify each case if the point satisfied the exponential function
<u>case A</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function not passes through the point
<u>case B</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function passes through the point
<u>case C</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function not passes through the point
<u>case D</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function passes through the point
therefore
<u>the answer is</u>
3 is the answer beacause she can build a domaind, square, and a rectangle
I think the answer is $560
working:
$875 * 64% = $560
Answer:
La edad actual de Beatriz es de:
30 años
Step-by-step explanation:
Planteamiento:
5e = 4b
(e+3) + (b+3) = 60
e = edad actual de José
b = edad actual de Beatriz
Desarrollo:
de la segunda ecuación del planteamiento:
e + b + 6 = 60
e + b = 60 - 6
e + b = 54
e = 54 - b
sustituyendo este último valor en la primer ecuación del planteamiento:
5(54-b) = 4b
5*54 + 5*-b = 4b
270 - 5b = 4b
270 = 4b + 5b
270 = 9b
b = 270/9
b = 30
e = 54 - b
e = 54 - 30
e = 24
Comprobación:
5e = 4b
5*24 = 4*30 = 120
