Simplify the following expressions. Put your a (3x³-5x² - 7+ 4x4) + (9x4 - 10x² - 5x³ + 3) =

leonid [27]

first we need to get rid of the ( ) so that we can see what the question really says

(3x³-5x² - 7+ 4x4) + (9x4 - 10x² - 5x³ + 3)

= 3x³-5x²-7+4x⁴+9x⁴-10x²-5x³+3

now all we need to do is add up the numbers with the same x's

3x³-5x²-7+4x⁴+9x⁴-10x²-5x³+3

= 13x⁴-2x³-15x²-4

What is the equation of the line that passes through (-3,-1 ) and has a slope of 3/5

vfiekz [6]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point (-3, -1) and the slope m = 3/5. Substitute:

$y-(-1)=\dfrac{3}{5}(x-(-3))\\\\y+1=\dfrac{3}{5}(x+3)\qquad\text{use distributive property}\\\\y+1=\dfrac{3}{5}x+\dfrac{9}{5}\qqua\text{subtract 1 from both sides}\\\\y=\dfrac{3}{5}x+\dfrac{4}{5}\qquad\text{multiply both sides by 5}\\\\5y=3x+4\qquad\text{subtract 3x from both sides}\\\\-3x+5y=4\qquad\text{change the signs}\\\\3x-5y=-4$

Answer:

point-slope form: y + 1 = 3/5(x + 3)

slope-intercept form: y = 3/5x + 4/5

standard form: 3x - 5y = -4
