Complete the equation of the line whose slope is - 2 and y-intercept is (0,3).

Kisachek [45]

Answer:

y = -2x+3

Step-by-step explanation:

The slope intercept form of an equation is

y = mx+b where m is the slope and b is the y intercept

We have a slope of -2 and a y intercept of 3

y = -2x+3

Find becky's mistake Choose 1

ss7ja [257]

Hi there!

mistake= step 2..

If you can see, the equation is the opposite so this means that to find the answer, your gonna have to add first.. instead of subtracting..

1.Add the terms:

$7+\frac{5}{4}=7\frac{5}{4}$

2.Simplifly the terms:

$7\frac{5}{4}=7\frac{25}{20}$

$\frac{4}{5}=\frac{16}{20}$

3.Subtract the terms:

$7\frac{25}{20}-\frac{16}{20}=7\frac{9}{20}$

Therefore, the mistake was step 2...

What is the inverse of f(x)=x^4+7 for x>0 where function g is the inverse of function f? -

Ann [662]

Answer:

$g(x) = \sqrt[4]{x-7},~ x\geq 7$

Step by step explanation:

$y= f(x) = x^4+7\\\\\text{Replace x with y and solve for y:}\\\\~~~~~~~x = y^4 +7\\\\\implies y^4 = x-7\\\\\implies y = \pm\sqrt[4]{x-7}\\\\ \implies f^{-1}(x) = \pm\sqrt[4]{x-7}$

find the equation of a line through (2,4) and parallel to y= 4x-2. write equation using function notation

iragen [17]

Parallel lines have the same slope.

We have y = 4x - 2 → slope m = 4.

Therefore we have y = 4x + b. Put the coordinates of the point (2, 4) to the equation of line:

4 = 4(2) + b

4 = 8 + b subtract 8 from both sides

-4 = b → b = -4

<h3>Answer: y = 4x - 4</h3>
