Which ratio is different from the other three 2/5 610 8/20 12:30

agasfer [191]

When we make decimals of all the fractions, we would get the following:

$\frac{2}{5} = 0.4$
$\frac{6}{10} = 0.6$
$\frac{8}{20} = 0.4$
$\frac{12}{30} = 0.4$

As you can see, all the numbers equal 0.4, with the exception of 6/10. Hence, the number with the other ratio is 6/10.

Find the product and simplify your answer. -n(-2n4+9n-5)

Harman [31]

Answer:

$+2n^5 - 9n^2 + 5n$

Step-by-step explanation:

To solve the expression

$-n(-2n^4+9n-5)$

first we will multiply -n with each term and then find their products.

When doing multiplication the powers will be added and co-efficient will be multiplied.

$-n(-2n^4+9n-5)\\-n(-2n^4) -n(+9n) -n(-5)\\+2n^5 - 9n^2 + 5n$

create a linear function f(x), whose graph has the given slope that meets the given condition. slope of -7, f(-5)=2

sergejj [24]

Our goal is to fit the given information into the slope-intercept form.
y=mx+b

We can place the slope in 'm.'
y= -7x+b

Then, input the values for the x and y.
2= -7(-5)+b
2=35+b
b=2-35
b= -33

'b' is the intercept, so now that we know that, we can plug in all the values and find our final equation.

y= -7x -33
