Answer:

y = 3x

Step-by-step explanation:

y = 13

x= 4

here

y∝x

that is

y= k x where k is constant

Since the equation is in the formy=kx we know that

13=K×4

k=13/4=3.25

so we can write this

y = 3.23 x ≅ 3x

Which transformations have been applied to the graph of f(x) = x2 to produce the graph of g(x) = –5x2 + 100x – 450? Check all th
madam [21]

Consider the function g(x) =-5x^2 + 100x- 450. First you need to simplify it by expressing the perfect square:

g(x) =-5x^2 + 100x- 450=-5(x^2-20x+90)=-5(x^2-2\cdot x\cdot 10+10^2-10^2+90)=-5((x-10)^2-100+90)=-5(x-10)^2+50.

So you get g(x) =-5(x-10)^2+50.

Now you can consider all transformations that have been applied to the graph of f(x) = x^2 to produce the graph of g(x):

  1. translate the graph of the function f(x) right 10 units - this transformation gives you the graph of the function f_1(x)=(x-10)^2;
  2. reflect graph of the function f_1(x) about the x-axis. This transformation gives you the graph of the function f_2(x)=-(x-10)^2;
  3. stretch the graph of the function f_2(x) in the y-direction by multiplying the whole function by 5, then you get the function f_3(x)=-5(x-10)^2;
  4. translate the graph of the function f_3(x) up 50 units, then you get the graph of the function g(x) =-5(x-10)^2+50.

From the algorithm above you can conclude that choices B, E and F are correct.

Find the solution of the inequality
Salsk061 [2.6K]

Answer:

option D

x≥3

Step-by-step explanation:

Given in the question an inequality

−4x + 2 ≤ −10

rearrange x terms to the left and constant to the right

-4x  ≤ −10 - 2

-4x  ≤ -12

cancel - on both sides, due to sign change inequality will also be change

 4x ≥ 12

  x ≥ 12/4

  x ≥ 3

So, the solution of the inequality is x ≥ 3, x is greater than or equal to 3.

Which relationship is likely ONLY a correlation and NOT one of causation?
gogolik [260]
"Correlation does not imply causation<span>" is a phrase used in </span>statistics<span> to emphasize that a </span>correlation<span> between two variables does not imply that one </span>causes the other. Correlation is the relationship between two sets of variables used to describe or predict information. Causation<span>, also known as cause and effect, is when an observed event or action appears to have caused a second event or action.

Hope this helps. :)</span>
