Which number line shows all the values of that make the inequality - 3x +1 < 7 true? ​

Mathematics

Yakvenalex [24]3 years ago
5 0

Answer:

D

Step-by-step explanation:

First, simplify the equation.

-3x+1<7

-3x<6

x>-2 (the sign flips because you are dividing by negative)

> means x is greater than -2 so the line will go towards the right.

Because the sign is >, the dot is open.

You drive your car for 4.5 hours at an average speed of 70 miles per hour how far did you go
SVEN [57.7K]
In this question, you are given the average speed of the car(70miles per hour) and the time of car travel(4.5 hours). The information is enough to find the car travelling distance. The equation would be:

Distance traveled= average speed * duration= 70miles/h * 4.5 h= 315miles

Which function's graph has x-intercepts at x=−1 and x=3, and a vertex at point (1,−4)?
Luda [366]

Answer:

Top right option: g(x) = (x+1)(x-3)

Step-by-step explanation:

x=-1 is the solution to x+1=0

x=3 is the solution to x-3=0

Therefore, your expression so far is (x+1)(x-3) or x²-2x-3.

Since the vertex must be (1,-4) we must check if x=1 satisfies the equation x=-b/2a:

x=-b/2a

1=-(-2)/2(1)

1=2/2

1=1

Both sides are equal to each other, so the final function is g(x) = (x+1)(x-3)
