Answer:

x < -5

Step-by-step explanation:

We have that The solution set for -the inequality 4x+10≥5x+55​ is mathematically given as

From the question we are told

What is the solution set for -4x+10≥5x+55​

Generally the equation for the Inequality is mathematically given as

Therefore

-4x + 10>5+55

-9x > 45

x < -5

The solution set for -the inequality 4x+10≥5x+55​ is mathematically given as

Answer:

C

Step-by-step explanation:

1. subtract 5x on both sides

-9x+10>55

2. subtract 10 on both sides

-9x>45

3. divide both sides by 9

x<-5

(sorry I didn't have the less than or equal to & more than or equal to sign

What is the equation of the line of the best fit for the following data? Round to the slope and y-intercept of the line to three
BigorU [14]

Answer:

D. y=-0.927x+13.634

Step-by-step explanation:

We graph the points on the graph. The graph is attached.

Let us take two points (1, 14) and (15, 1), and calculate the slope mbetween them <em>(we choose these points because the line passing through them will be the best fit for all points) </em>

m=\frac{14-1}{1-15} =\frac{13}{-14} =-0.9286

Thus we have the equation

y=-0.9286x+b

Let us now calculate b from the point (1,14)

14=-0.9286(1)+b

b=14.9286

So the equation we get is

y=-0.9286x+14.9286

Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D. y=-0.927x+13.634 is the closest one, so we pick it.
