Answer:
a) y = .70x + 20
-To find this, use the rate as x since it will change based on the number of miles. Since 20 is a flat fee, it can be added at the end as a constant.
b) This graph forms a straight line.
-This is because the answer in a is a linear equation.
c) The slope is .70 and the y-intercept is 20.
-For this one, the y-intercept is always the constant at the end of the equation and the slope is the coefficient of x.
Answer:
208.........not sure but this can be the ans
Answer:
100*x + 14*y
Step-by-step explanation:
Tenemos que en el sistema decimal un número de 3 cifras se representa de este modo:
100*x + 10*y + z
También es llamado descomposición polinómica y de esta manera podremos encontrar la expresión algebraica.
Nos dicen la relación entre unidades y decenas, 4 veces mayor las unidades que las decenas, por lo tanto:
z = 4*y
Reemplazamos y nos queda:
100*x + 10*y + 4*y
reduciendo nos queda:
100*x + 14*y
Por lo tanto esta sería la expresión algebraica.
M+k because the subtraction sign and negative cancel out to become positive
Hey!
First, let's write the problem.
Multiply
with
.
Subtract
from both sides.
Divide both sides by
.
