Answer:

a = 11 , b = 2

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]

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

Answers

Answer:

x = 9 when y = 39

Step-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 Multiply

13x = 117

Step 2: Divide both sides by 13

13x / 13 = 117 / 13

x = 9

Step 3: Check

3 / 13 = 9 / 39

117 = 117 ✅

x = 9 when y = 39

-3 (4b - 10) = 114
What does b equal?

Answers

Answer:

b = -9.5

Step-by-step explanation:

-3 (4b - 10) = 144

-12b + 30 = 144

       -30      -30

-12b = 114

/-12      /-12

b = -9.5

Hope this helps!

Divide both sides by the numeric factor on the left side, then solve.
b = -7

First fine the slope.
How?
2 random points and plug them in the slope formula.
In this case :
(-3,0)(0,4) —> 4-0/0-(-3) = 4/3 <— slope
The y intercept is the point where x equals 0
In this case :
(0,4) —> 4 is the y-Intercept
Now, plug in for the equation y= mx + b ( m = slope and b = y intercept)
y = 4/3x + 4

Mr. Richard plans to take 25 students on a school trip. They plan to go to Zoo. The bus fee is $100 for the entire trip. Entrance fee is $2.50 per person. How much should each student pay? Note: Mr. Richard does not need to pay.

Answers

Answer:

$162.50

Step-by-step explanation:

+$100

25x2.50= $62.50

+$62.50

100+62.50=162.50

Answer:

Each student should pay $6.50

Step-by-step explanation:

The question is not very clear.

If Mr. Richard has to pay to enter:

Total cost = $100 + ($2.50×26) = $165

Cost per student = [tex]\frac{165}{25}[/tex] = $6.60

Each student should pay $6.60

If Mr. Richard doesn't have to pay to enter:

Total cost = $100 + ($2.50×25) = $162.5

Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50

Each student should pay $6.50

Solve for z.
12 = 15(z-1/5

Answers

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

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.

Answers

She is not correct, because there are no solutions.

Explanation: If you isolate the absolute value by adding 1 both sides of the equation, you get -|2x-10|=3. There are no solutions, because the left side of the equation will always be negative and will never equal 3.

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.

[AP]

Answers

Answer:  0

=======================================================

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.

write 28 + 24 as a product of two factors using the GCF and the distributive property

Answers

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).
