If the graph y= 9x + 4 is translated 4 units up what equation describes the new graoh

The equation that would describe the original equation <span> y= 9x + 4 translated 4 units up would be y = (9x + 4) + 4 = y = 9x + 8. The new graph would be 4 points higher than the parent function which changes the y-intercept of the function however it will still have the same slope.</span>

HELP!!!!
OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here.  It's very simple to follow:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

which, for us, looks like this:

d=\sqrt{(13-4)^2+(19-7)^2} and

d=\sqrt{9^2+12^2} and

d=\sqrt{81+144} and

d=\sqrt{225} so

d = 15

at a particular school 50% of students travel by bus. if this represents 600 children how many children attend the school
hichkok12 [17]

Answer:

1200 students at the school

Step-by-step explanation:

Let x be the total number of students at the school

50% ride the bus

600 students ride the bus

x*50% = 600

Changing to decimal form

.50x = 600

Divide each side by .5

.50x/.5 = 600/.5

x =1200

1200 students at the school

Josh is going to the store to buy candy. Bags of candy corn cost $3 and bags of chocolate cost $5. He needs to buy at least 20 b
tino4ka555 [31]

Answer:

x + y ≥ 20

3x + 5y > 60

Step-by-step explanation:

Let

Bags of candy corn = x

Bags of chocolate = y

Cost of bags of candy corn = $3

Cost of bags of chocolate = $5

He needs to buy at least 20 bags of candy and he cannot spend more than $60

system of linear inequalities to model the situation.

x + y ≥ 20

3x + 5y > 60

The system ot inequalities which models the situation

x + y ≥ 20

3x + 5y > 60

Determine whether each equation below is linear or nonlinear.
Kruka [31]

Answer:

A) y=\frac{1}{2}x+3 - Linear

B) y=4x+2 - Linear      

C) xy=12 - Nonlinear

Step-by-step explanation:

To determine whether a function is linear or nonlinear.

The function of a straight line is given as :

y=mx+b

where m represents slope of line and b represents the y-intercept.

Any function that can be represented as a function of straight line is called a linear function otherwise it is nonlinear.

We will check the equations given for linear or nonlinear.

A) y=\frac{1}{2}x+3

The function is in the form y=mx+b and hence it is a linear function with slope m=\frac{1}{2} and y-intercept b=3.

B) y=4x+2

The function is in the form y=mx+b and hence it is a linear function with slope m=4 and y-intercept b=2.

C) xy=12

On solving for y

Dividing both sides by  x

\frac{xy}{x}=\frac{12}{x}

y=\frac{12}{x}

This function cannot be represented in the form y=mx+b, hence it is a nonlinear function.

Which equation has solution x = -3?
vladimir1956 [14]
Hi Brainiac

1/2(2x-6) = -6
We need to distribute
(1/2)(2x) + (1/2)(-6) = -6
2x/2 + -6/2 = -6
x - 3 = -6
x = -6 + 3
x = -3
Thus, The answer is D

I apologize for the late answer :(
