2x+3y=12
if y=8
what is x

Answers

Answer 1

Answer:

-6

Step-by-step explanation:

2x + 3(8) = 12

2x + 24 = 12

2x = 12 - 24

2x = -12

x = -12/2

x = -6

2x+3y=12if Y=8what Is X
Answer 2
X=-6

2x+3y=12
2x+3(8)=12
2x+24=12
-24 -24

Because it is extremely hard to find the area of this figure all together, it would be in our best interest to split this figure up into three different pieces: the two horizontal rectangles, and the verticle rectangle. We can find the area of all three and add them up. Be aware that there are two different ways that you can break this figure up, As shown in the attachments. I will be using the first image (the one with the tall horizontal rectangles, NOT the almost-squares).

So, we see that we have enough information to solve for the area of the left-most rectangle. Area = lw. 10 x 4 = 40, so the area is 40. Next, we have to notice, that the horizontal rectangles are also the same, so both of the areas of the two horizontal rectangles are 40.

Now, we can find the middle rectangle. We know that the length of the entire thing is 18, but it is taken up by 8 (4+4) of the horizontal triangles, so 18-8=10, so the length Is 10. We also know that the height of the horizontal rectangles is 10, so 10-3=7. Our dimensions for the rectangle are 10x7 or 70 square units. If we add them all together, 40+40+70=150.

The area is 150 square units

Answers

Answer:

m∠b = m∠r

Step-by-step explanation:

The triangle was reflected across line m.

A reflection is a rigid transformation. A rigid transformation does not change the measurement or size of a shape, so the pre-image and the image are congruent.

The angles on the pre-image corresponds to the angles on the image. This also is for line segments.

This means (for angle measurements):

Angle A is congruent to Angle P

Angle C is congruent to Angle S

Angle B is congruent to Angle R

Option D should be the correct answer.

After two six-sided dice are rolled, what is the probability that the dice faces add up to either a 4 or 6?
0.222
0.139
0.167
0.083

Answers

Answer:

0.222

Step-by-step explanation:

out of 36 outcomes you have 8 possible outcomes for a '4' or '6':

1,5

5,1

3,3

2,4

4,2

2,2

1,3

3,1

8/36 = 2/9 = .2 repeating

The probability that the dice faces add up to either 4 or 6 is 0.222.

What is Probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

Here, After two six sided dice are rolled,

Hence, Total outcomes = 36

So, Probability of getting sum 4 that is,  {(1, 3), (2, 2), (3, 1)};

P = 3/36    

And, Probability of getting sum 6 = 5/36

Hence, Total Probability of getting sum either 4 or 6 = 3/ 36 + 5/36

                                                                         = 8/36

                                                                         = 2/9

                                                                         = 0.222

Thus, the probability that the dice faces add up to either 4 or 6 is 0.222.

Select the correct answer. What is the range of function m? m(x) = √x - 3 + 1​

Answers

Answer:

i think it is b

Step-by-step explanation:

The range for m is [3, ∞)

What is function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

m(x)= √(x- 3) + 1

For x= 0

m(0) = √(-3) + 1

m(0) = √3i + 1

So, m ≠ 0, 1, 2 because it leads to imaginary value.

Thus, m ≥ 3

i.e., m=4

m(3)= √3-3 + 1= 1

and, m(4)= √(4- 3)+ 1 = 2

Hence, the range for m is [3, ∞)

Miguel withdrew $20 per week from his bank account for 4 weeks. Which expression shows the change in his account balance?
A. -20+4
B. -20-4
C. -20x4
D. -20 ÷4

Answers

Answer:

c

Step-by-step explanation:

The expression that shows the change in Miguel's account balance is -20×4. Thus, option (C) is correct.

Given, Miguel withdrew $20 per week from his bank account for 4 weeks.

Since he withdrew money, the change in his account balance would be negative.

The expression -20 represents the amount he withdrew each week, and the -4 represents the number of weeks.

Multiplying 4 with the initial balance of -20 gives us the change in his account balance.

Therefore, the expression -20×4 correctly represents the change in Miguel's account balance.
