North America burned 4.5 x 1016 btu of petroleum in 1998. At this rate, how many BTU's will be burned in 9 year?

1 answer:

4 0

Hello. Sonny solving this equation, multiplying 4.5 by 1016 will give us 4,572 BTU's a year. However, we are looking for the amount looking for the amount that will burn in 9 years. When you multiply 4,572 by 9, you get 41,148. 41,148 BTU's will be burned in 9 years.

Answer:

Kevin and Vijay are chatting

Step-by-step explanation:

Consider: Kevin=k

Heather=h

Randyor=v

Vijay=v

Abby=a

The values or the variables can be =o if they are not chatting and =1 if they arre chatting, then:

k+h>=1

v+r=1

a=r

v=k

if h=1 then a=1 and k=1, then as a=r, r=1 and as v=k, v=1, but then v+r=2, which is not possible because v+r=, then we can fisrt conclude than h=0.

.As k+h>=1, and h=0, then k=1. As k=v, then v=1.

As v+r=1, and v=1, then r=0. As r=a, a=0

So in conclusion, a=0, r=0, v=1, k=1 and h=0, so Kevin and Vijay are chatting

Does the point (-4, 3) fall on the graph of this line? How do you know? Show your work. ( 2 points) PLEASE HELP ILL MARK BRAINLI

Elanso [62]

Answer:

Step-by-step explanation:

Since we know the line goes through points $(8,9)$ and $(2,4)$ , we can construct a line in slope-intercept form

$y = mx + b$

where $m$ is the slope and $b$ is the Y-intercept.

The slope can be found using the two points provided:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$\frac{9 - 4}{8 - 2}$

$\frac{5}{6}$

The line is now represented as

$y = \frac{5}{6}x + b$

To solve for $b$ , we can plug in one of the two points:

$y = \frac{5}{6}x + b$

$(9) = \frac{5}{6}(8) + b$

$4 = \frac{20}{3} + b$

$b = \frac{-8}{3}$

We know have our line:

$y = \frac{5}{6}x - \frac{8}{3}$

To determine if the point $(-4, 3)$ falls on this line, we just plug the numbers into the equation and see if it holds true:

$y = \frac{5}{6}x - \frac{8}{3}$

$(3) = \frac{5}{6}(-4) - \frac{8}{3}$

$3 = \frac{-10}{3} - \frac{8}{3}$

$3 = \frac{-18}{3}$

$3 = -6$

This does not hold true, so the point is not on the line.

Line L is Parallel to Line M. Find the value of x and y (pls help asap)

LenaWriter [7]

Answer:

x = 9 and y = 13

Step-by-step explanation:

10x - 17 and 8x + 1 are Alternate Exterior angles so they equal the same.

So we are going make them equal each other.

10x - 17 = 8x + 1 ( plus 17 on both sides)

10x = 8x + 18 (subtract 8x on both sides)

2x = 18 (divide by 2)

x = 9

PLUG IN 8(9) + 1 = 73 so...

6y + 29 + 73 = 180 (two angle next to each other have to equal 180)

6y + 102 = 180 ( subtract 102 on both sides)

6y = 68 (divide by 6 on both sides)

y = 13

PLUG IN

6(13) + 29 = 107
