Find the values of x and y that satisfy both the equations
12x + 3y = 15 and 2x – 3y = 13.​

Answers

Answer 1

Answer:

X=1 and Y=1 in the first question

Step-by-step explanation:

simply 12X means 12*x, so x=1 and 12*1+3*1=15 question 1

and question 2

2X means 2*X x=8 so 2*8=16 so 16-3 because Y=1 and

16-3=13

Please show explanation ​

Answers

Answer:

35 and 15

Step-by-step explanation:

7+3=10

50÷10=5 so you multiply each number by five

7×5=35

and

3×5=15

Step-by-step explanation:

let the number be 7x &3x

now,

7x+3x= 50

10x=50

x=50

10

x=5

again,

7x=7×5 = 35

3x= 3×5 =15

therefore the two number are 35 & 15.

What is the value of x?

Answers

x=12 because say if we choose the base line as our example then the baseline for the small triangle is 7 and the baseline for the bigger triangle is 28. To get from 7 to 28 you have to times by 4 , so the triangle has been enlarged by 4. If we get the side where it says 25 (for the smaller triangle) we can times it by 4 to get 100. Our equation is now 100=6x+28. To work this equation out you do -28 for both sides which equals to 72=6x.
Then we divide by 6 on both sides to get our answer as 12=x

find the median of this set of numbers 5,11,2,12,4,2​

Answers

Step-by-step explanation:

2,2,4,5,11,12

the median is 5

Answer:

2, 2, 4, 5, 11, 12 (put the numbers from least to greatest)

since it's an even set of numbers, the median is between two of the numbers. so find where the middle is by counting how many numbers you have, and then dividing by 2. in this case it's 3, so there should be 3 values on either side of the median. so the median is between 4 and 5. So you add those two values together and divide by 2 (because that's how many numbers you added) and you get 4.5 as your median.

Answer:

A. [tex] y = \frac{1}{4}x + 2 [/tex].

Step-by-step explanation:

Equation of a line in slope-intercept form, is given as [tex] y = mx + b [/tex].

Given a slope (m) of ¼, and y-intercept (b) of 2, we can get the equation if the line by substituting m = ¼, and b = 2 into [tex] y = mx + b [/tex].

Thus, the equation of the line would be:

[tex] y = \frac{1}{4}x + 2 [/tex].

−4(m+3)=24
What does m=

Answers

Answer: m= -9

Step-by-step explanation: First use distributive property, -4(m) is -4m and -4(3) is -12. Then you have -4m -12 =24. Then use 12 and add it to the other side of the equation, cause of the subtraction sign, 12+24=36. Then you have -4m=36. Then divide the 4 to get the m by its self. 36 divided by -4 is -9. Your answer is m=-9

Solve the quadratic equation by completing the square.

Answers

Answer:

x'1 = -1

x'2 = 8

Step-by-step explanation:

Answer:

x = - 1, x = 8

Step-by-step explanation:

Given

x² - 7x - 8 = 0 ( add 8 to both sides )

x² - 7x = 8

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- [tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] = 8 + [tex]\frac{49}{4}[/tex] = [tex]\frac{81}{4}[/tex]

(x - [tex]\frac{7}{2}[/tex] )² = [tex]\frac{81}{4}[/tex] ( take the square root of both sides )

x - [tex]\frac{7}{2}[/tex] = ± [tex]\sqrt{\frac{81}{4} }[/tex] = ± [tex]\frac{9}{2}[/tex] ( add [tex]\frac{7}{2}[/tex] to both sides )

x = [tex]\frac{7}{2}[/tex] ± [tex]\frac{9}{2}[/tex]

Thus

x = [tex]\frac{7}{2}[/tex] - [tex]\frac{9}{2}[/tex] =  [tex]\frac{-2}{2}[/tex] = - 1

x = [tex]\frac{7}{2}[/tex] + [tex]\frac{9}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8
