if y varies directly with X and Y=24 when x=6, find x when y = 32
Answers
Answer:
8
Step-by-step explanation:
if y varies with x, then they are directly proportional, so their ratio is constant (ie x divided by y is allways the same)
when x = 6, y = 24:
y / x = 4
when y = 32:
32 / x = 4
so x = 32 / 4 = 8
y=24
To get to 24, you multiply x by 4
x= ____
y=32
To get x, start with y and do the reverse, dividing by 4. 32/4=8
So, x=8

Step-by-step explanation:
Edge 2020
A correct option is an option (b)
Given,
The function is [tex]y=6.4 cos(\frac{\pi x}{26})+12[/tex]
For minimum hours of sunlight, [tex]cos(\frac{\pi x}{26})[/tex] should have the lowest value, that is -1 for [tex]x=26[/tex] {because [tex]cos (\pi )=-1[/tex] is the lowest value of cosine function}
Thus.
[tex]y_{minimum} = -6.4 + 12 \\y_{minimum}= 5.6[/tex]
So, the option is an option (b)

Can someone help me with 14 and a few others I need help ):
Answers
Answer:
26, -0.85, 17
Step-by-step explanation:
hi! so for 14, you can plug in -11 for every x in the equation.
f(-11)= 15-(-11)
=15+11
=26
your answer is 26.
for 15, we can plug in 0.3 for x.
g(0.3)=-2.5(0.3)-0.1
= -0.75-0.1
= -0.85
your answer is -0.85.
for 16, you can plug in -17 for x.
f(-17)= -(-17)
=17
your answer is 17.
Answer:
14: 26
15: -8.5
16: 17
Step-by-step explanation:
The f(x) basically gives you what x is, as the inside of parenthesis means the value of x. You then can plug in x into the equation for each of the equations. Whenever you get something like 24- (-42) The negatives cancel out and you add the two values together instead.

karinne hit 4 more home runs than 1/2 the number of home runs Lu hit. Together they hit 10 home runs. Let X represent the number of home runs Lu hit. Write an equation to represent the situation
Answers
It is given that Lu hit x numbers of home run.
So, number of home run hit by Karinne is more home runs than 1/2 the number of home runs Lu hit.
So, number of home run Karinne hit is :
[tex]y = 4 + 0.5x[/tex]
Also,
[tex]x + y = 10[/tex]
Solving above two equation, we get :
x + ( 4 + 0.5x ) = 10
1.5x + 4 = 10
1.5x = 6
x = 4
Therefore, number of home run hit by Lu is 4.
Hence, this is the required solution.
Creating a mathematical expression using the scenario described, the expression which represents the total number of home runs is 1.5x + 4 = 10
Total Number of home runs :
(1/2)x + 4 + x = 10
1.5x + 4 = 10
1.5x = 10 - 4
1.5x = 6
x = 6/1.5
x = 4
Therefore, the equation which represents the situation is 1.5x + 4 = 10

It is B
Step-by-step explanation:
If you find the perimeters of each of the rectangles, you get 11x2, 15x2, and then 19x2
How did I get the x2?
All you have to do is add the length and width together, but it only gives half of the perimeter as there is another half at the other corner of the rectangle. The 11, 15, and 19 was from adding the 4s with the 7s. In the first rectangle, you do 7+4 equals 11, but you have to multiply it by 2, hence the first sentence at the beginning. Then you can find the slope, or the rate of change, as it increases by intervals of 8. The four that is added to every extra rectangle added to it is multiplied by 2, because there is another four at the other side of the rectangle. Then you can find the answer using process of elimination because B, is the only answer that the y-values increase by 8, while the x-values increase by 1, as the x values are counting how many rectangles are in each rectangle.
