In the second and third line, where 3x was taken off both sides. On the left -3x-3x should have given -6x.
3x should have been added to both sides in order to cancel out the -3x

The domain of f(x) is {-2,0,1}. If f(x) = 4x+1, what is the range?

bekas [8.4K]

The range of function is: {-7,1,5}

Step-by-step explanation:

Given function is:

$f(x) = 4x+1$

Also the domain: {-2,0,1}

In order to find the range,, we have to put the domains values in the function

So,

Putting x = -2

$=4(-2)+1\\= -8+1\\=-7$

Putting x = 0

$=4(0)+1\\= 0+1\\=1$

Putting x = 1

$=4(1)+1\\= 4+1\\= 5$

Hence,

The range of function is: {-7,1,5}

Keywords: domain, range

If 60% of a number is 90, what is 4/5 of the number?

sukhopar [10]

Answer:

120

Step-by-step explanation:

Let the required number be x

So,

60% of x = 90

0.6x = 90

x = 90/0.6

x = 900/6

x = 150

$\frac{4}{5} x = \frac{4}{5} \times 150 = 4 \times 30 = 120 \\$

Answer:

The slope intercept form is $y=\frac{1}{2}x-5$

Step-by-step explanation:

Given : Equation $y+3=\frac{1}{2}(x-4)$

To find : Rewrite the equation in slope-intercept form ?

Solution :

The slope-intercept form is $y=mx+c$

Equation $y+3=\frac{1}{2}(x-4)$

$y+3=\frac{1}{2}x-\frac{1}{2}\times 4$

$y+3=\frac{1}{2}x-2$

$y=\frac{1}{2}x-2-3$

$y=\frac{1}{2}x-5$

Therefore, the slope intercept form is $y=\frac{1}{2}x-5$
