How to I find this?<br><br> What percent of 60 is 42?

Tpy6a [65]

So let's put it this way-
N% x 60 = 42
You want to isolate the variable
42/60 = N%
42/60 is .7 which is 70%
Hope this helps :)

1. Consider f(x) = 3x - 5

Rzqust [24]

Answer:

3

Step-by-step explanation:

Here we have the function

$f(x)=3x-5$

We want to find the following ratio:

$\frac{f(x+h)-f(x)}{h}$

Note that the limit of this for $h\rightarrow 0$ is equivalent to the derivative of the function.

Here we have:

$f(x+h)=3(x+h)-5=3x+3h-5$

And

$f(x)=3x-5$

Therefore we have

$f(x+h)-f(x)=3x+3h-5-(3x-5)=3h$

And therefore,

$\frac{f(x+h)-f(x)}{h}=\frac{3h}{h}=3$

Find a set of parametric equations for y= 5x + 11, given the parameter t= 2 – x

Sati [7]

Answer:

$x = 2-t$ and $y = -5\cdot t +21$

Step-by-step explanation:

Given that $y = 5\cdot x + 11$ and $t = 2-x$ , the parametric equations are obtained by algebraic means:

1) $t = 2-x$ Given

2) $y = 5\cdot x +11$ Given

3) $y = 5\cdot (x\cdot 1)+11$ Associative and modulative properties

4) $y = 5\cdot \left[(-1)^{-1} \cdot (-1)\right]\cdot x +11$ Existence of multiplicative inverse/Commutative property

5) $y = [5\cdot (-1)^{-1}]\cdot [(-1)\cdot x]+11$ Associative property

6) $y = -5\cdot (-x)+11$ $\frac{a}{-b} = -\frac{a}{b}$ / $(-1)\cdot a = -a$

7) $y = -5\cdot (-x+0)+11$ Modulative property

8) $y = -5\cdot [-x + 2 + (-2)]+11$ Existence of additive inverse

9) $y = -5 \cdot [(2-x)+(-2)]+11$ Associative and commutative properties

10) $y = (-5)\cdot (2-x) + (-5)\cdot (-2) +11$ Distributive property

11) $y = (-5)\cdot (2-x) +21$ $(-a)\cdot (-b) = a\cdot b$

12) $y = (-5)\cdot t +21$ By 1)

13) $y = -5\cdot t +21$ $(-a)\cdot b = -a \cdot b$ /Result

14) $t+x = (2-x)+x$ Compatibility with addition

15) $t +(-t) +x = (2-x)+x +(-t)$ Compatibility with addition

16) $[t+(-t)]+x= 2 + [x+(-x)]+(-t)$ Associative property

17) $0+x = (2 + 0) +(-t)$ Associative property

18) $x = 2-t$ Associative and commutative properties/Definition of subtraction/Result

In consequence, the right answer is $x = 2-t$ and $y = -5\cdot t +21$ .
