Answer:

plug in whatever you found for x and see if its equal on both sides.

Step-by-step explanation:

Answer:

To check an answer for an equation, you can substitute the answer you've found in place of the variable you solved it for.

The value of the unknown, x, can be plugged into the equation. You can then compare both sides to see if they are equal.

For your given equation, let's substitute 1 for x in the equation you've given.

3x + 5 = x + 7

3(1) + 5 = 1 +7

Simplify this.

3 + 5 = 8

8 = 8

You know that 8 does equal 8, so your value for x is correct.

I hope this helps you ^^

Good luck :)

Answer:

y = -2x - 5

Step-by-step explanation:

x1 = -3 , y1 = 1  ; m = -2

point slope form : y - y1 = m(x -x1)

y - 1 = -2(x - [-3])

y - 1 = -2(x + 3)

y - 1 = -2x + 3*(-2)

y - 1 = -2x - 6

    y = -2x - 6 + 1

    y = -2x - 5

Answer:

The value of k determines where the parabola is on the y-axis. In other words, its "height". If k we're to be positive, the parabola would move to the positive side of y-axis, not negative.

Answer:

A rotation and a translation

or

rotation

Step-by-step explanation:

Again, we have to rotate to make the shape fit in, right?

But it wouldn't fit... Or will it? If you can take 2 guesses, you can try the rotation and a translation or the rotation.

Sorry, I'm also getting confused at some point :(!

Answer:

  (a)  Reflection and rotation

Step-by-step explanation:

The order of the vertices in the original polygon CDEF is clockwise. The order of vertices in the image polygon GEIH is counterclockwise. This means a reflection is involved in the transformation. Rotation with or without translation will not reverse the orientation.

The only choice that includes reflection is ...

  A reflection and a rotation

__

A reflection alone cannot do the transformation shown. A reflection together with rotation and/or translation will do it. For example, reflection across the y-axis, and 90° counterclockwise rotation about the point F'. Or, reflection across the line y=-x and translation right 3 and down 1.

Answer:

H0: p1=p2    against the claim Ha: p1≠p2

Step-by-step explanation:

Here the proportion of the people going for medical checkup before the program is p1= 0.76

The proportion of the people going for medical checkup after the program is p2= 686/880=0.78

Our null and alternate hypothesis will be

H0: proportion of the people going for medical checkup before the program is equal to the proportion of the people going for medical checkup after the program

against the claim

Ha:  proportion of the people going for medical checkup before the program is not equal to the proportion of the people going for medical checkup after the program

Mathematically this can be written as

H0: p1=p2    against the claim Ha: p1≠p2

Answer:

  $4444.44

Step-by-step explanation:

The amount of interest on a given principal is found by ...

  I = Prt . . . . principal P earning annual rate r for t years.

We want ...

  400 = P×0.09×1

  P = 400/0.09 ≈ 4444.44

Alex needs to borrow $4444.44.

_____

Additional comment

For exactly $400 in interest, the amount is not an integral number of cents, so some rounding of interest or loan amount must occur. In that case, the minimum to borrow is that which will give a calculated interest of at least $399.995. That amount is $399.994/0.09 ≈ $4444.3888.... ≈ $4444.39. Alex can borrow a minimum of $4444.39 and still have to pay $400 in interest.

Answer:

Step-by-step explanation:

Answer:

270 = 15,268.14030 in³

Step-by-step explanation:

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and do not round your answer)?

Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³

Using a typical ten digit calculator

3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)

Volume of cylinder = pi x r^2 x height

Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.

Multiply the volume of a cylinder by total candles:

56.52 x 270 = 15,260.4 cubic cm

Answer:

pay,  say, dip, day,  pal,  spa, pas.

Step-by-step explanation:

The number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.

Arrangement of the things or object is mean to make the group of them in a systematic order, in all the possible ways.

The number of possible ways to arrange is the n!.

Here, n is the number of objects.

The given letter in the problem is DISPLAY. There is total 7 letters in this word. Now here three words have to be selected.

Here, all the 7 letters are different, thus the combination of selecting  three letters from the 7-letter word (DISPLAY) can be given as,

[tex]^7C_3=\dfrac{7\times6\times5}{3\times2\times1}\\[/tex]

[tex]^7C_3=35[/tex]

Thus the number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.
