BRAINLIESTTTTTTTTTTTTT!

Mathematics
1 answer:
astraxan [27]3 years ago

Ok for question in the picture : the y axis is measured in gallons not hours. So niether one of the choices with 10 and 50 in them are correct. The gallons go up from 10-50gallons during the time interval 4<x<7 hours. So, the first answer choice is correct.

1. for this one I would just plug in the point (7,-2) to each answer choice because they all have a slope of -3.
y+2 = -3(x-7)
-2+2= -3(7)+21
0=0
after plugging them in I got the third answer choice is correct.

Any questions?

Find the equation of a line that passes through points (1,8) and (4,4).​
daser333 [38]

Step-by-step explanation: Using the equation, y = mx + b, the slope-intercept form, plug in the values you have and solve for b. (m is the slope.) You have y = -8 and x = 4 and m = 1/2.

Will give 99 points and brainliest
Jobisdone [24]

Answer:

First page

a: 0.864

b: x = 7, -8.75

Second page:

Domain: (3, ∞)

Range: (-∞, ∞)

Asymptote: x = 3

Third page:  About 464 visitors

Step-by-step explanation:

See first attached photo for page 1 work

Second page:  A log argument must be positive (the number in the log x place), so and number for x greater than 3 will satisfy this requirement.  

x - 3 > 0,   so x > 3

The range of a log x fucntion is (-∞, ∞),

Since x ≠ 3, there is a vertical asymptote at x = 3, the graph will not cross the line x = 3

*See second attached photo for the graph

Third page:  Take the visitors of one year, and divide it by the visitors of the previous year to determine the % growth.  

EX:  from 2003 to 2004 the number of visitors grew from 310 to 322, a % change of

322/310 = 1.07, or 7%

Do this will all the years and you will see that each year there was about a 7% growth.  

So in year 2009, there will be 434(1.07) = 464.38 visitors, or about 464 visitors

A triangle has side lengths of 20 cm, 99 cm, and 108 cm. Classify it as acute, obtuse, or right.
Tasya [4]
This doesn't make sense, as a triangle much equal 180, so it cannot have two angles bigger than 90, because this would mean it cannot be acute. A right triangle has one angle that is 90, obtuse as one that is bigger than 90 and two that are less, and an acute has three angles less than 90. Maybe there's a typo here?
