(2x-3)^2=81
If x is a solution to the equation above and x > 0, what is the value of x?
X=

Answers

Answer 1

Answer:

putting roots on both sides,

[tex] \sqrt{(2x - 3)} {}^{2} = \sqrt{81} [/tex]

or, 2x-3 =9

or, 2x= 9+3

or, 2x = 12

Or, x = 12÷2

:. x=6

Marc is creating a rectangular garden in his backyard. The length of the garden is 18 feet. The perimeter of the garden must be at least 60 feet and no more than 76 feet.

Then the inequality is given as,

60 < 2(W + 18) < 76

Simplify the inequality, then the value of the width W will be

60 < 2(W + 18) < 76

30 < (W + 18) < 38

12 < W < 20

Thus, the value of the width will be from 12 to 20.

Find the extraneous solution of the equation |4x−42|=−10x.

Answers

Answer:

x=3 is the extraneous solution

Step-by-step explanation:

|4x-42| = -10x

Since it's absolute value and we know that there are two possibilities, we need two equations to set up to solve for x.

1st equation:

4x - 42 = -10x

2nd equation:

4x - 42 = 10x

Solve both equations for x:

1st equation:4x - 42 = -10x14x-42 = 014x=42x = 32nd equation:4x-42=10x-6x-42=0-6x=42x=-7

Plug in both values for x in the original equation to find the extraneous solution:

x=-7

|4x-42|=-10x|4(-7)-42|=-10(-7)|-28-42|=70|-70|=7070=70

x=3

|4x-42|=-10x|4(3)-42|=-10(3)|-30|=-3030≠-30

1. In part (b) of the example, why isn't AB a correct answer? 2. In part (c) of the example, would KJL be an appropriate answer?

Answers

Answer:

Step-by-step explanation:

1. AB isn't a correct answer because it only refers to the part of the line between point A and point B. This is incorrect because it doesn't represent the whole line which goes on infinity past point A (as seen by the arrow).

2. KJL would not be an appropriate answer because the points must be listed in the same order that they appear in direction of the line. The angle shown is angle K so K should be the middle letter as it is the middle point with the angle. KJL would not be appropriate because it would refer to the angle J if there was another line between J and L.

what’s the slope-intercept form of y + 3 = 4(x - 5),

Answers

Slope-intercept form is: y = mx + b

m = slope

b = y-intercept

y + 3 = 4(x - 5)

Distribute the 4

y + 3 = 4x - 20

Subtract 3 from both sides.

y = 4x - 23

Answer:

Step-by-step explanation:

Slope intercept form...

y=mx+c

where, m=slope

c=intercept

y + 3 = 4(x - 5)

Open the Brackets.

y + 3 = 4x - 20

SUBTRACT 3 FROM BOTH SIDES.

y + 3 (-3)= 4x - 20 (-3)

Take note of the signs and solve.

y = 4x - 23

4 is the slope.

-23 is the intercept.

Car A is moving twice as fast as car B. Car B starts 174. Meters in front of car A. If car A passes car B in 27 seconds, how fast is car B going.

Answers

Answer: The speed of car B is 6.44 m/s

Step-by-step explanation:

Let's define:

Sa = Speed of car A.

Sb = Speed of car B.

I assume that at t = 0s, the position of car A is 0m (then at t = 0s, the position of car B is 174m)

Then we can write the positions of each car as:

Pa(t) = Sa*t

Pb(t) = Sb*t + 174m.

We also know that Sa = 2*Sb.

And we know that at t= 27s, car A passes car B.

Then at t = 27s, the positions of both cars must be the same:

Pa(27s) = Pb(27s)

Sa*27s = Sb*27s + 174m.

Now we can replace Sa by 2*Sb (from the above equation)

2*Sb*27s = Sb*27s + 174m

Now we can solve this for Sb.

2*Sb*27s - Sb*27s = 174m

Sb*27s = 174m

Sb = 174m/27s = 6.44m/s.

The speed of car B is 6.44 m/s
