Answer:

y = 2x

As you can see 2 times x would equal to y in this situation so the constant of variation would be y=2x

Hope it is right and helped :3

If f(x-3)=x^2-4x+5, what's f(1-x)

olganol [36]

Answer:

$\large\boxed{f(1-x)=x^2-4x+5}$

Step-by-step explanation:

$f(x-3)=x^2-4x+5\\\\f((x-3)+3)\to\text{put x + 3 to the equation of the function:}\\\\f(x-3+3)=(x+3)^2-4(x+3)+5\\\text{use the distributive property and}\ (a+b)^2=a^2+2ab+b^2\\f(x)=x^2+2(x)(3)+3^2+(-4)(x)+(-4)(3)+5\\f(x)=x^2+6x+9-4x-12+5\qquad\text{combine like terms}\\f(x)=x^2+(6x-4x)+(9-12+5)\\f(x)=x^2+2x+2\\\\f(1-x)\to\text{put 1 - x to the equation of the funtion f(x):}\\\\f(1-x)=(1-x)^2+2(1-x)+2\\\text{use the distributive property and}\ (a-b)^2=a^2-2ab+b^2$

$f(1-x)=1^2-2(1)(x)+x^2+(2)(1)+(2)(-x)+2\\f(1-x)=1-2x+x^2+2-2x+2\qquad\text{combine like terms}\\f(1-x)=x^2+(-2x-2x)+(1+2+2)\\f(1-x)=x^2-4x+5$

1. What is the correct way to write 3,350,000 in scientific notation? * O 3.35 x 10^6 O 3.35 x 10^10 335 x 10^5 O 335 x 10^9

Tomtit [17]

We have the following:

$3350000=3.35\cdot1000000=3.35\cdot10^6$

therefore, the answer is 3.35 x 10^6

Brainiest for correct answer

yarga [219]

Answer:

angle a = 104 degrees, angle b = angle c = 123 degrees

Step-by-step explanation:

angle c = 180 - 57

angle c = 123 degrees

angle a = 180 - 76

angle a = 104 degrees

angle b = 180 - 57

angle b = 123 degrees

Please help... How many odd perfect squares are between 5 and 211?

frez [133]

Answer:

we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Step-by-step explanation:

Let us check by taking squares

3² = 9

5² = 25

7² = 49

9² = 81

11² = 121

13² = 169

As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.

Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6
