Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount

IrinaK [193]

Answer:

25 times

Step-by-step explanation:

To find how many times he visited, plug in 85 as y and solve for x:

y = 3x + 10

85 = 3x + 10

75 = 3x

25 = x

So, Carlos visited the gym 25 times

Let f (x)=x^2+2x-35 enter the x-intercepts of the quadratic function in the boxes __and___

serious [3.7K]

Answer:

The x-intercepts of the quadratic function are -7 and 5.

Step-by-step explanation:

The given function is

$f(x)=x^2+2x-35$

Equate f(x)=0, to find the x-intercepts of the function.

$x^2+2x-35=0$

$x^2+7x-5x-35=0$

$x(x+7)-5(x+7)=0$

$(x+7)(x-5)=0$

$x+7=0\Rightarrow x=-7$

$x-5=0\Rightarrow x=5$

Therefore the x-intercepts of the quadratic function are -7 and 5.

If the graph of the equation y=(x+2)^2 is reflected with respect to the y-axis, what is the equation of the resulting graph?

alexandr1967 [171]

Answer:

Is important to remember that the reflection of the point (a,b) across the y-axis is the point (-a,b).

Our original equation is $y= (x+2)^2$

And after the reflection respect x we got:

$y= (-x+2)^2$

Step-by-step explanation:

Is important to remember that the reflection of the point (a,b) across the y-axis is the point (-a,b).

Our original equation is $y= (x+2)^2$

And after the reflection respect x we got:

$y= (-x+2)^2$
