Find the x-intercept of the line whose equation is 8x + 2y =4

Alex787 [66]

Answer:

<h2>x - intercept= 1/2</h2>

Step-by-step explanation:

$8x + 2y =4\\Substitute ,y for ;0\\8x+2(0)=4\\8x+0=4\\8x=4\\\frac{8x}{8} =\frac{4}{8} x = 1/2\\(\frac{1}{2} , 0) -x-intercept$

METHOD 2

$(-\frac{c}{a} , 0)\\a = 8\\b = 2\\c = -4\\\frac{-(-4)}{8} \\x-intercept = \frac{4}{8} \\\\x-intercept = \frac{1}{2}\\(1/2 , 0)$

Of the two bottles shown of sunblock shown, which is the better buy? Explain. Sunblock 1: 4 ounce bottle $8.49 Sunblock 2: 5 oun

Pepsi [2]

8.49/4 = 2.1225

Sunblock 1 costs $2.12 per ounce of sunblock.

10.29/5 = 2.058

Sunblock 2 costs $2.06 per ounce of sunblock.

Sunblock 2 is the better buy because it is cheaper ounce-per-ounce.
