Answer:

They are not Congruent = A

Step-by-step explanation:

Its not congruent because the left one is slightly a little bit bigger than the right. If you look close enough you can see that. Plus if you add the lines together the right one is slightly tilted.

Answer:

a = 1.5

Step-by-step explanation:

Given:

-3√123 = -2√123 x ------

Assume;

Blank = a

Computation:

a = -3√123 / -2√123

a = 3 / 2

a = 1.5

Answer:

C. Distribute 4 to (6 - x).

Step-by-step explanation:

Person above is right.

Juan’s first step should be C. Distribute 4 to (6 – x).

Suppose a, b and c are three numbers. Then we have:

a(b + c) = a b + a c

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

We are given an equation as;

4(6 – x) = 12

Here Juan wants to solve the equation, using the Distributive Property.

thus, 4(6 – x) = 12

First step is to distribute 4.

4(6) – 4(x) = 12

Then solve;

24 - 4x = 12

x = 3

Hence, Juan’s first step should be C. Distribute 4 to (6 – x).

Answer:

work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

Answer:

Step-by-step explanation:

You can cross multiply (15 x 13095) = 40x

196425 = 40x

divide by 40

x = 4,910.625

x = 4,911

Step-by-step explanation:

The nth term of a geometric progression can be determined by using the formula:

Tn=arn−1

where: a = first term and r = common ratio

Substitute the given values of first term and common ratio into the formula:

Tn=arn−1

T5=(40)(0.5)5−1

T5=(40)(0.5)4

T5=(40)(0.0625)

T5=2.5

Step-by-step explanation:

Step 1: Define Equation

3(4x - 5) - 4x + 1 = -6

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -6 does indeed equal -6.

∴ x = 1 is the solution to the equation.

Answer:

The temperature in the greenhouse was at least 68 degrees before the heater stopped working.

Step-by-step explanation:

It was at 68 then it dropped by 2 degrees.

Step-by-step explanation:

22+15x=34-17x

So now, the 34 will join the 22 and the 15x will join the -17x

22-34=-17x-15x

-12=-2x

So now, we divide both sides by -2x

and the negative will cancel negative so

x=6

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 27 are: 1, 3, 9, 27

Then the greatest common factor is 9.

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

Start point: (5,6)

End point: (-5,12)

rate of change = (12-6) / (-5-5) = 6/-10 = - 3/5 = - 0.6

Answer:

The rate of change is -0.6

Step-by-step explanation:

Given

[tex](x_1,y_1) = (5,6)[/tex]

[tex](x_2,y_2) = (-5,12)[/tex]

Required

Determine the rate of change

The rate of change means the slope (m) and it is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{12-6}{-5-5}[/tex]

[tex]m = \frac{6}{-10}[/tex]

[tex]m = -\frac{6}{10}[/tex]

Simplify the fraction

[tex]m = -\frac{3}{5}[/tex]

[tex]m=-0.6[/tex]

The rate of change is -0.6

Answer:

X = 5 and Y = 8

Step-by-step explanation:

4x + 3y = 44

3x + 3y = 39

- - -

__________

x = 44 - 39

x = 5........eq 1

Now putting the values in any equation

4 ( 5 ) + 3 y = 44

20 + 3 y = 44

[tex]4(5) + 3y = 44[/tex]

[tex]20 + 3y = 44[/tex]

[tex]3y = 44 - 20[/tex]

[tex]3y = 24[/tex]

[tex]y = \frac{24}{3} [/tex]

[tex]y = 8[/tex]
