Answer:

g(-3)=42

Step-by-step explanation:

Given:

g(x)=4x^2+6

Let's substitute -3 for x

g(-3)=4(-3)^2+6

Now, let's solve

g(-3)=4(9)+6

g(-3)=36+6

g(-3)=42

Hope this helps

G(-3)=42 or g(x)=42 or 42
(Not sure how your program would write the answer)
Basically what you do is input -3 into wherever there is an x. So the equation would become 4(-3)^2+6 which equals 42

Masja [62]

Answer:

about 26 min

Step-by-step explanation:

Toni rows a boat 4.5 km/h upstream and then turns around and rows 5.5 km/h back downstream to her starting point

First we find the average speed

We add both speed and divide it by 2

\frac{4.5+5.5}{2} = 5

Now we find the distance for round trip

given total time is 48 mins. convert mins into hours

48 mins = 48 divide by 60 = 0.8

average speed = 5 km/hr

Distance = speed * time = 5 * 0.8 = 4 km

distance covered both ways = 4 km

so 4 divide by 2 = 2 km each way

To find time taken for upstream = distance of each way / speed of upstream

time = \frac{2}{4.5} = 0.44 hours

Now convert hours into minutes

0.44* 60= 26.4 minutes

Describe how you could represent the fraction 4/10 using a model or number line. Dont make the answer huge thank you
Rzqust [24]

Answer:

As a model for representing fractions, the number line differs from other models (e.g., sets, regions) in several important ways. First, a length represents the unit, and the number line model suggests not only iteration of the unit but also simultaneous subdivisions of all iterated units. That is, the number line can be treated as a ruler.

PLEASE I NEED HELP WITH BOTTOM PART WILL MARK BRAINLIEST!!
kipiarov [429]

Answer:

13.

parallel: y = 1/3x -3

perpendicular: y = -3x - 3

14.

parallel: y = 4x - 1/2

perpendicular: y = -1/4x - 1/2

15.

parallel: y = -2x + 4

perpendicular: y= 1/2x + 4

16.

parallel: y = -2x-2

perpendicular: y= 1/2x-2

17.

parallel: y = -2x+8

perpendicular: y= 1/2x + 8

Step-by-step explanation:

A perpendicular has a negative reciprocal slope and a parallel has the same slope
