Point K is on line segment JL. Given JK = 2x – 2, KL

Scorpion4ik [409]

Answer:

KL = 10

Step-by-step explanation:

JK + KL = JL

2x – 2 + x – 9 = 2x + 8

Combine like terms

3x -11 = 2x+8

Subtract 2x from each side

3x-2x -11 = 2x+8-2x

x-11 = 8

Add 11 to each side

x-11+11 = 8+11

x = 19

KL = x – 9

= 19-9

= 10

How many seconds are there in a month of 30 days express it in scientific notation

Evgesh-ka [11]

Answer: 2.592 x 10^6 seconds

Explanation:

There are 3600s in 1 hr

And 24hrs in 1 day which mean

There are 3600 x 24 = 86400s in 1 day

And one month = 30 days

86400 x 30 = 2, 592, 000s in 1 month

Write in scientific notation:

2, 592, 000 = 2.592 x 10^6

Find a solution of the linear inequality. y ≥ 4x – 5 a. (1, 1) b. (2, 1) c. (3, 4) d. (3, 0)

frez [133]

Answer:

$A(1,1)$

Step-by-step explanation:

we have

$y\geq 4x-5$

we know that

If a ordered pair is a solution of the inequality

then

the ordered pair must be located on the shaded area of the solution of the inequality

Using a graphing tool

Graph the inequality and plot the points

$A(1,1),B(2,1),C(3,4),D(3,0)$

see the attached figure

The point A is located on the shaded area

therefore

the point A is a solution of the inequality

\frac{x}{4}=\frac{\frac{1}{36}}{x}\\
\\
x^2=4.\frac{1}{36}\\
\\
x^2=\frac{1}{9}\\

Given the function f(x) = 2x-5 and g(x), which function has a greater slope?

adell [148]

Answer:

g(x) has a greater slope

Step-by-step explanation:

step 1

Find the slope of f(x)

we have

$f(x)=2x-5$

This is a linear function in slope intercept form

$f(x)=mx+b$

where

m is the slope

b is the y-intercept

so

$m=2$

step 2

Find the slope of g(x)

take two points from the table

(2,0) and (4,5)

$m=(5-0)/(4-2)\\m=5/2=2.5$

step 3

Compare the slopes

$2.5 > 2$

so

The slope of g(x) is greater than the slope of f(x)
