Phantasy [73]

Answer:

1.y−7=3(x+3)

2.y=3x+16

Step-by-step explanation:

use point-slope formula to find the slope and plug it into the equation

y-y₁=m(x-x₁)

slope= - $\frac{y2-y1}{x2-x1}$

plug in the value of x and y from both of the coordinates into this equation and then use one set of points and slope to get your equation

Simplify the expression 4x(2x2 − 7x + 3).<br> This one is killing me..

Papessa [141]

$Use:\\distributive\ property:a(b+c)=ab+ac\\commutative\ property:a\cdot b=b\cdot a\\assiocative\ property:a\cdot(b\cdot c)=(a\cdot b)\cdot c\\and\ a^n\cdot a^m=a^{n+m}\\-----------------------\\\\4x(2x^2-7x+3)=(4x)(2x^2)+(4x)(-7x)+(4x)(3)\\\\=(4\cdot2)(x^1\cdot x^2)-(4\cdot7)(x^1\cdot x^1)+(4\cdot3)(x)\\\\=8x^{1+2}-28x^{1+1}+12x\\\\=\boxed{8x^3-28x^2+12x}$

lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together

mezya [45]

Answer:

$\frac{5}{6}$ quarts

Step-by-step explanation:

Total amount of drinks = $\frac{1}{3}$ + $\frac{1}{2}$

You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.

$\frac{1}{3}$ + $\frac{1}{2}$ = $\frac{2}{6}$ + $\frac{3}{6}$
