I believe that -3 is less than 3x-6 because if you look at their graph -3’s graph is below 3x-6 graph

Which phrase best describes the scatterplot below?

Vikentia [17]

Answer:

Strong negative correlation

Step-by-step explanation:

n the scatter plot attached below, as the variable in the x-axis increases, the variable on the y-axis decreases. Thus, if a line of best fit is drawn, it would show a line that slopes downwards to our right. This shows a negative correlation between both variables in the scatter plot.

Also, we also see that the data points represented on the scatter plot are clustered more closely along the slope, showing strong negative correlation.

Therefore, the phrase that best describes the scatter plot is: strong negative correlation.

Olve the two-step equation and identify the steps. 2 = − 7 4 + 1 4 x

saul85 [17]

Answer:

x = 5.142

Step-by-step explanation:

2=-74+14x

if you want to make x the subject (work out its value), you need to single out x

1) the first thing that we can do is get rid of the -74

2) do this by adding it on to both sides of the equation. This is called the inverse

2+-74=-72 -74+14x=14x

-72=14x

3) to get x on its own, we now need to get rid of the 14

REMEMBER: 14x = 14×x

4) We do the inverse by dividing both sides by 14

-72÷14=-5.142...

its surprising that its not an integer

5.142=x

x=5.142

PLEASE LET ME KNOW IF THIS IS CORRECT

Simplify the expression. What classification describes the resulting polynomial? (3x^2-11x-4)-(2x^2-x-6)

Gnoma [55]

The expression can be simplified to a polynomial of degree 2.

$x^2 - 10x + 2$

<h3>How to simplify the expression?</h3>

Here we have the expression:

$(3x^2 -11x - 4) - (2x^2 - x - 6)$

We can directly simplify this by taking the variable as common factor:

$(3 - 2)*x^2 + (-11 + 1)*x + (-4 + 6)\\\\x^2 - 10x + 2$

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.

How long did it take to reach the bottom of the slope

mafiozo [28]

To solve this we are going to use the kinematic equation for final velocity: $V_{f}=V_{i}+at$
where
$V_{f}$ is the final velocity
$V_{i}$ is the initial velocity
$a$ is the acceleration
$t$ is the time

We know for our problem that the the velocity at the beginning of the slope is $2.0ms^{-1}$ , so $V_{i}=2.0$ . We also know that the speed ad the bottom of the slope is $20ms^{-1}$ , so $V_{f}=20$ . We also know that the acceleration is $6ms^{-2}$ , so $a=6$ . Lets replace those values in our formula and solve for $t$ :
$V_{f}=V_{i}+at$
$20=2+6t$
$6t=18$
$t= \frac{18}{3}$
$t=3$ seconds

We can conclude that it takes the roller coaster 3 seconds to reach the bottom of the slope.
