Mathematics
1 answer:
Norma-Jean [14]3 years ago
6 0

Answer:

Step-by-step explanation:

4x + 15 = 3

Subtract 15 from both sides

4x + 15 - 15 = 3 - 15

4x = -12

Divide both sides by 4

4x/4 = -12/4

x = -3

Check:

substitute x = -3 in the LHS of the  equation,

4*(-3) + 15 = -12 + 15

                 = 3 = RHS

50 PONITS! Only help if you know the answer please and thank you!
Ghella [55]

Answer: (-x,y)

Step-by-Step Explanation:

In geometry, when a figure is reflected over particularly the y-axis, one coordinate will change.

The y coordinate will remain the same, not value wise. (positive in your case.)

Wherease the x coordinate will be the opposite additive inverse.

For example if you have (4,3) and it is reflected over the y-axis, the new coordinate will be (-4,y)

Hope this helps! :)

Which of the following represents “6 less
kykrilka [37]

Answer:

C) 3x - 6

Step-by-step explanation:

Let the unknown number be represented by placeholder x.

Then the product of 3 and the number is represented by 3*x or 3x.

This value diminished by 6 corresponds to 3x-6.

So the expression representing the required overall construct mathematically is given by 3x-6

Option a, 6x-3 represents the difference of 6 times x and 3.

Option b, 3-6x represents the difference of 3 and (6 times x).

Option d, 6-3x represents the difference of 6 and (3 times x).

Find an equation of the line that contains the point (-1,3) and is parallel to the line x+3y=6.
Bas_tet [7]

Answer:

Step-by-step explanation:

3y = -x + 6

y = -1/3x + 2

y - 3 = -1/3(x + 1)

y - 3 = -1/3x - 1/3

y - 9/3 = -1/3x - 1/3

y = -1/3x + 8/3

15 POINTS I REALLY NEED HELP!!!!!!!!!!!!!!!!!!!!!The solution to 16x = 48 is x = ___. (Only input the number.) Numerical Answers
AlexFokin [52]
<em>Hello there, and thank you for asking your question here on brainly.

<u>Short answer: 3
</u>
Why?

You can find this out by dividing 48 and 16. The number you get from it is how much 16s are in 48, which is the answer to our question. (48 / 16 ==> 3) Check: 16 * 3 = 48. This is correct.

Hope this helped you! ♥</em>

What is the length of MN
Lina20 [59]

The Pythagorean theorem is: a²+b²=c², and "c" will always be the hypotenuse or the longest side of the triangle.

In order to find MN you can make a triangle, and then you can find the lengths of the other sides(a and b).

You should get a = 4 and b = 6. Next you plug these numbers into the equation.

(4)² + (6)² = c²

16 + 36 = c²

52 = c²

√52 = c
