Answer:

d < -3

Step-by-step explanation:

Move the constant to the right-hand side and change its sign:

2.5d <  - 1.3d - 11.4

Move the variable to the left-hand side and change its signs:

2.5d + 1.3d < 11.4

Collect like terms:

3.8d <  - 11.4

Divide both sides of the inequality by 3.8:

3.8 \div  - 11.4 =  - 3

Therefore, the answer is d < -3.

Answer:

d < -3

Step-by-step explanation:

2.5d+11.4<-1.3d

3.8d+11.4<0

3.8d<-11.4

d < -3

Just isolate and solve for x and remember, what you do to one side, you must do to the other.

Hope this helps!

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a measure of how similar two datasets are acting.

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases and other data starts to decrease in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

The correlation shown by the graph is negative.

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).

What is an equation of the line that passes through the points (-4,1) and (4,4)?
Ray Of Light [21]

Answer:

y = \frac{3}{8} x +  \frac{5}{2}

Step-by-step explanation:

☆Remember: m =  \frac{y_2 - y_1}{x_2 - x_1}

☆Remember: Slope-intercept form -> y = mx + b

☆Now. We first need to find the slope.

m =  \frac{4 - 1}{4 -  (- 4)}  =  \frac{3}{8}

☆Now the y-intercept.

y =  mx + b \\  \\ 4 =  \frac{3}{8} (4) + b \\  \\ 4 =  \frac{3}{2}  + b \\   \frac{ -  \frac{ 3}{  2} =  -  \frac{ 3}{ 2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  }{ \frac{5}{2} = b }
