Answer:

infinite solutions

Step-by-step explanation:

If the left side equals the right side, then every value you input for the variable will make a TRUE statement --> which means there are infinite solutions.

For example: x + 1 = x + 1

Any value you choose for "x" will result in a true statement.

This is because they are the same line, which is another way of showing that they have infinite solutions.

If LK=MK, LK=7x-10,KN=x+3, MN=9x-11 and KJ=28 find LJ

beks73 [17]

Suppose J, K, L, M, N are points on the same line.

MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14

Since LK = MK and LK = 7x - 10, then

7x - 10 = 8x - 14

8x - 7x = -10 + 14

x = 4

LJ = MK + KJ

MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18

LJ = 18 + 28 = 46

Use a linear approximation to estimate the number (8.07)^2/3.

Tanya [424]

So let f(x) = x^(2/3)
Then let f'(x) = 2/3 x^(-1/3) = 2 / (3x^(1/3)) 

When x = 8, 
f(8) = 8^(2/3) = 4 
f'(8) = 2 / (3*8^(1/3)) = 1/3 

So near x = 8, the linear approximation is 
f(x) ≈ f(8) + f'(8) (x - 8) 
f(x) ≈ 4 + 1/3 (x - 8) 

So the linear approximation for x = 8.03 is... 
f(8.03) ≈ 4 + 1/3 (8.03 - 8) 
f(8.03) ≈ 4 + 1/3 (0.03) 
f(8.03) ≈ 4.01 

8.03^(2/3) ≈ 4.01

There is a bag with only red marbles and blue marbles.

natulia [17]

Answer:

There must be 35 red marbles.

Step-by-step explanation:

This question can be solved using a rule of three.

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability of randomly choosing a red marble is 7/9.

This means that for each set of 9 marbles, 7 must be red.

There are 45 marbles in total in the bag and each is equally likely to be chosen. Work out how many red marbles there must be.

How many red marbles out of 45?

7 red - 9 marbles

x red - 45 marbles

$9x = 45*7$

Simplifying by 9

$x = 5*7$

$x = 35$

There must be 35 red marbles.

PLEASE ANSWER! (BRAINLIEST)

gavmur [86]

First, find the distance AB by the formula:

$AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}.$

If A(0,-7) and B(8,8), then

$AB=\sqrt{(8-0)^2+(8-(-7))^2}=\sqrt{8^2+15^2}=\sqrt{64+225}=\sqrt{289}=17.$

Dilating polygon ABCD by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′, you increase the distance AB twice, A'B'=2AB. Thus, A'B'=2·17=34 units.

Answer: AB=17 units, A'B'=34 units.
