A line has a slope of -1/4 and passes through point (-5/4, 1) What is the equation of the line?

Vedmedyk [2.9K]

The line of the equation would be y = -1/4x + 11/16.

In order to find that, we'll put the ordered pair and the slope into slope intercept form. Then we can solve for the intercept.

y = mx + b
1 = -1/4(-5/4) + b
1 = 5/16 + b
11/16 = b

So then we put that in the equation with slope for the final equation.

What is the answer and how do you solve 21x^3/3x^−1

Sunny_sXe [5.5K]

Answer:

as written: 7x^2

perhaps intended: 7x^4

Step-by-step explanation:

As written, the Order of Operations specifies that the only denominator factor is 3, so the expression is interpreted as ...

$\dfrac{21x^3}{3}x^{-1}=\dfrac{21}{3}x^{3-1}=7x^2$

___

Sometimes grouping of denominator factors is intended, but parentheses are not written as they should be. If the intention is ...

21x^3/(3x^-1)

then the simplification is ...

$\dfrac{21x^3}{3x^{-1}}=\dfrac{21}{3}x^{3-(-1)}=7x^4$

_____

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^b/a^c = a^(b-c)

To get on the top players list , don needs to have a minimum average score of 225 after playing four games. His scores on his fi

Black_prince [1.1K]

Average must be 225 or more
4 games so
$\frac{score1+score2+score3+score4}{4} \geq 225$
score1=192
score2=214
score3=250
score4=?
so
$\frac{192+214+250+?}{4} \geq 225$
$\frac{656+?}{4} \geq 225$
times both sides by 4 to clear fraction
656+?≥900
minus 656 from both sides
?≥244

min score is 244
