The value of y varies directly with x. If x = 3, then y = 13. Show your work for finding the value of x when y = 39
Answer:
x = 9 when y = 39Step-by-step explanation:
To solve this, we will use a proportion, since x varies directly with y, each will increase proportionately to the other.
3 / 13 = x / 39
Step 1: Cross Multiply13x = 117
Step 2: Divide both sides by 1313x / 13 = 117 / 13
x = 9
Step 3: Check3 / 13 = 9 / 39
117 = 117 ✅
x = 9 when y = 39what is the rule for gallons

Solve for z.
12 = 15(z-1/5
Answer:
z= 1
Step-by-step explanation:
Rewrite the equation as
15(z−1/5)z12
Apply the distributive property
15z+15(−1/5)= 12
Cancel the common factor of 5
15z+3*−1= 12
Multiply 3 by −1
15z−3= 12
Divide each term by 15 and simplify
5z−1 = 4
Since the expression on each side of the equation has the same denominator, the numerators must be equal
5z−1= 4
Move all terms not containing z to the right side of the equation
5z= 5
Divide each term by 5 and simplify
z = 1

3. Lim
x-infinity
x² +6x²+1/
x²+3
[AP]
=======================================================
Explanation:
Let n be the degree of the numerator
Let d be the degree of the denominator
If n < d, then the limit at infinity is always 0. This is because the denominator is growing faster compared to the numerator. I suggest looking at a table of values to see this in action.
In this case, n = 3 and d = 4, so we see that n < d is the case here. So that's why the answer is 0.
----------------------
Side notes:
If n = d, then the limit at infinity is equal to a/b, where a and b are the leading terms of the numerator and denominator. If n > d, then the numerator is growing faster than the denominator, meaning the ultimate result is infinity.BRAINLIEST ANSWER WILL GET BRAINLIEST

Step-by-step explanation:
[tex]\frac{(4-\sqrt{5})(4+\sqrt{5}) }{2\sqrt{11}} = \frac{ \sqrt{a}}{y} \\Hence,\\\frac{4^2-(\sqrt{5})^2 }{2\sqrt{11}} = \frac{ \sqrt{a}}{y}\\\frac{16-5}{2\sqrt{11} } = \frac{ \sqrt{a}}{y}\\\frac{11}{2\sqrt{11}} = \frac{ \sqrt{a}}{y}\\\frac{\sqrt{11}*\sqrt{11} }{2\sqrt{11}} = \frac{ \sqrt{a}}{y}\\\frac{\sqrt{11} }{2} = \frac{ \sqrt{a}}{y}\\a=11,b =2[/tex]

Misha found that the equation –|2x – 10| – 1 = 2 had two possible solutions: x = 3.5 and x = –6.5. Which explains whether or not her solutions are correct?
She is correct, because both solutions satisfy the equation.
She is not correct, because she made a sign error.
She is not correct, because there are no solutions.
She is not correct, because there is only one solution: x = 3.5.
She is not correct, because there are no solutions. (Option C).
What is an equation?An equation refers to any mathematical statement that contains the equality sign. Now we can see in the equation that there is a negative sign before the absolute value.
Now we have;
–|2x – 10| – 1 = 2
–|2x – 10| = 3
This is not possible because the absolute value does not return a negative value and the expression can never equal 3.
Thus, she is not correct, because there are no solutions.

The larger of two numbers is sixteen less than twice the smaller number. If the sum of the numbers is 44, find the two numbers. Write your answer as two numbers separated by a coma.
Answer:
20, 24
Step-by-step explanation:
smaller: x
larger: 2x - 16
x + 2x - 16 = 44
3x -16 = 44
3x = 60
x = 20
smaller: x = 20
larger: 2x - 16 = 2(20) - 16 = 24

Answer:
x-intercept = (0, 2) or 2
y-intercept = (1, 0) or 1
Step-by-step explanation:
The x-intercept is where the line passes the x-axis, and the y-intercept is where the line passes the y-axis.
The line passes through the y-axis at (0, 2)
The line passes through the x-axis at (1, 0)

write 28 + 24 as a product of two factors using the GCF and the distributive property
Answer:
4 x 13
Step-by-step explanation:
GCD of 28 and 24 is 4
28 = 4 x 7
24 = 4 x 6
u take the 4 out
4 (7 + 6)
4 x 13
The product of two factors using the GCF and the distributive property is 4(13).
What is the meaning of the greatest common divisor/factor?
The largest integer of highest degree that is an exact divisor of each of two or more integers.
The greatest common divisor of 24 and 28
24=2×2×2×3
28=2×2×7
We can see that the 2 and 2 is common in 24 and 28
The GCD of 28 and 24 is=2×2= 4
For the distributive property we have
28 = 4 x 7
24 = 4 x 6
we take the 4 out
4 (7 + 6)
=4 x 13
Therefore the GCD is 4 and by distributive property product is 4(13).
