Solve for 45 points and explain well

Delicious77 [7]

Answer:

Step-by-step explanation:

$\text{The intercept form of an equation of a line:}\\\\\dfrac{x}{a}+\dfrac{y}{b}=1\\\\a-x\ intercept\\b-y\ intercept\\\\\text{We have:}\\\\point\ (2,\ 4)\to x=2,\ y=4\\a=c\\b=c\\\\\text{Substitute:}\\\\\dfrac{2}{c}+\dfrac{4}{c}=1\\\\\dfrac{2+4}{c}=1\\\\\dfrac{6}{c}=1\qquad\text{multiply both sides by}\ c\neq0\\\\6=c\to c=6$

$\text{Put it to the equation in the intercept form:}\\\\\dfrac{x}{6}+\dfrac{y}{6}=1\\\\\dfrac{x+y}{6}=1\qquad\text{multiply both sides by 6}\\\\x+y=6\qquad\text{subtract}\ x\ \text{from both sides}\\\\y=-x+6$

Help will mark brainliest

vlada-n [284]

Answer:

Step 1 : Plug values into the quadratic formula

x = -(-5) +/- √ (-5)^2 - (4)(2)(-3) / (2)(2)

Step 2 : Solve

x = 5 +/- √ 25 + 24 / 4

x = 5 +/- √ 49 / 4

x = 5 +/- 7 / 4

x1 = 5 - 7 / 4 AND x2 = 5 + 7 /4

x1 = -1/2 OR - 0.5

x2 = 3

Hope this helps!!
