If y varies directly as x and x=6 when y=0.5, find y when x=10
Answer:
y = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 6 when y = 0.5 , then
0.5 = 6k ( divide both sides by 6 )
[tex]\frac{0.5}{6}[/tex] = k , that is k = [tex]\frac{1}{12}[/tex]
y = [tex]\frac{1}{12}[/tex] x ← equation of variation
When x = 10, then
y = [tex]\frac{1}{12}[/tex] × 10 = [tex]\frac{10}{12}[/tex] = [tex]\frac{5}{6}[/tex]

Dawn says -2(-3)(4) is equal to 6(4). Javier says -2(-3)(4) is equal to -2(-12). Who is right? Explain
Answer:
Both of them
Step-by-step explanation:
-2*-3 = 6
So -2(-3)(4) is equal to 6(4).
-3*4 = -12
So -2(-3)(4) is equal to -2(-12).

Consider an equilateral triangle that is small enough to fit in your pocket. Now consider an equilateral triangle that is big enough to fill a movie screen! What must be true about the measure of each of the interior angles for these two triangles? Does the size of a triangle influence its angle measures? What about other polygons?
Answer:
Step-by-step explanation:
First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.
Second Question: No the size does not influence the size of the interior angle.
Third Question: That's true for all polygons. Size is not affect the interior angle size.

Solve for x.
4(5x−20)=−20
Enter your answer in the box.
x =?
Answer:
4(5x-20)=-20 should be x=3
Answer:
x = 3
Step-by-step explanation:
4(5x−20)=−20 | Given
20x - 80 = -20 | Distribute the number on the outside (multiply all numbers on the inside by the number on the outside, 4×5x and 4×-20)
20x = 60 | Add 80 to both sides (do the opposite operation, if its a negative number add it to both sides)
x = 3 | Divide both sides by 20x (20x turns into x and 60 turns into 3 via 60÷20)

Maureen is in charge of renting a climbing wall for the school’s fundraiser. The equation y = 170x represents the total cost of renting a climbing wall from Company A. The table shows the relationship between cost and rental time for Company B. The graph shows the relationship for Company C. Which company, if any, offers the best deal? Explain.
GRAPH COMPANY B:
2 340
3 510
4 680

4 700
5 875
PLEASE EXPLAIN NOT ONLY SAYING WHICH COMPANY ONLY??!!
Answer:
Company A and B
Step-by-step explanation:
For company A- 170 is the cost for one hour
For company B- 170 is the cost for one hour
For company C- 175 is the cost for one hour
So company A and B offer the best deal since they both offer $170 per hour.

What's 3/5 of 1/4?!!!!! Plz help me!
Answer:
2.4 or [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign.
Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:
[tex]\frac{12}{5}[/tex]

A=30 squared
A=900 square feet
Answer:
C) 900 square feet
Step-by-step explanation:
A = s^2
A = 30^2 ->30^2 is the same as 30 × 30
A = 900 square feet

Simplify the given equation.
17x - 6 + 3x - 5 = x + 11 + 4x
Answer:
x = 22/15
Step-by-step explanation:
17x - 6 + 3x - 5 = x + 11 + 4x
= (17x + 3x) (-6 - 5) = x + 11 + 4x
= 20x - 11 = x + 11 + 4x
= 20x - 11 = (x + 4x) + 11
= 20x - 11 = 5x + 11
= 20x - 5x = 11 + 11
= 15x = 22
Exact form: 22/15
decimal: 1.4666666...
mixed number: 1 7/15
Write the ratio 2 3/5 in simplest form.

If the function f has five distinct zeros, which of the following could represent the complete graph off in the xy-plane?
Answer:
The zeros of a function are the points where the graph of the function crosses the x-axis.
Clearly Graph in option D could be the function which has 5 zeroes as it passes through the axis at 5 points.
Step-by-step explanation:
The graph of the function will intersect the x-axis five times. Then the correct option is D.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
If the function f has five distinct zeros.
Then the graph represents the complete graph of the function in the xy-plane will be
We know that the zeroes of the function are the intersection points of the x-axis and the function.
That means the graph will intersect the x-axis five times.
Then the correct option is D.
