The graph of which of the following equation has x-intercept of 3 and 0 ?
Hatshy [7]

Answer:

From the given graph , The equation y =  x² - 3 x has x-intercept of 3 , 0

Step-by-step explanation:

Given as :

Let The standard equation of line

y = m x + c

where m is the slope of line and c is  y-intercept

For, x-intercept , put y = 0

For y-intercept , put x = 0

A) y = x + 3

for x-intercept , y = 0

So, 0 = x + 3

i.e x = - 3

B) y = x² + 3 x

for x-intercept , y = 0

So, 0 = x² + 3 x

i.e 0 =  x² + 3 x

Or,  x ( x + 3) = 0

Or, x = 0 , x = - 3

C) y = x² - 3 x

for x-intercept , y = 0

So, 0 = x² - 3 x

i.e 0 =  x² - 3 x

Or,  x ( x - 3) = 0

Or, x = 0 , x =  3

D) x = y² - 3 y

for x-intercept , y = 0

So, x = 0 - 0

i.e x = 0

Hence, From the given graph , The equation y =  x² - 3 x has x-intercept of 3 , 0 Answer

[6] Jessica sold one third of her records and then bought 84 more. She now has 178 records. How many records did Jessica begin w
tia_tia [17]

Answer:

  • 141 records

Step-by-step explanation:

Let the initial number be x

<u>Sold 1/3x, and now has:</u>

  • x - 1/3x = 2/3x

<u>Bought 84 more and now got 178:</u>

  • 2/3x + 84 = 178
  • 2/3x = 94
  • x = 94 ÷ 2/3
  • x = 94 × 3/2
  • x = 141

Jessica had 141 records initially
