How do you complete this task?
Assoli18 [71]

Answer:

-3/2

Step-by-step explanation:

y=mx +b

where m is the slope and b is the y intercept

we just need to rewrite 3x+2y+18=0 to look like that

We need to get y by itself

3x+18= -2y

we need y to be positive and to have no number in front of it (no coeficcent)

y= -3/2x-9

the slope is therefore -3/2

A bag contains pennies and nickels. You are given the number of pennies in the bag
stira [4]
There are 3 nickels because if you use the ratio 6 to 1 you multiply 6 by 3 to get 18 pennies and you do the same with the one and that’s how I got 3 nickels.

ad-work [718]

Answer:

The slope is 70

The slope represents the speed of your car

Step-by-step explanation:

The slope is 70, y = mx + c, where m is the slope

The slope represents the speed of your car

speed = distance/time

speed x time = distance

As y represents the distance you travel, x is the time, slope is the speed, you get the distance travelled.

F(x) =2x^2+12x-6 Does this function have a minimum or maximum value? What is this minimum or maximum value?
Alex777 [14]

Let's compare the given function with the model for a quadratic equation:

\begin{gathered} f(x)=ax^2+bx+b \\ a=2,b=12,c=-6 \end{gathered}

Since the value of a is positive, the parabola has its concavity upwards, and the function has a minimum value.

The minimum value can be found calculating the y-coordinate of the vertex:

\begin{gathered} x_v=-\frac{b}{2a}=-\frac{12}{4}=-3 \\  \\ y_v=2\cdot(-3)^2+12\cdot(-3)-6 \\ y_v=2\cdot9-36-6^{} \\ y_v=-24 \end{gathered}

Therefore the minimum value is -24.
