Answer:
y = 18
Step-by-step explanation:
y/3 - 4 = 2
y/3 = 6
y = 18
Answer:
y = (x + 1)²
Step-by-step explanation:
y = 1 + x² + 2x
⇒ x² + 2x + 1 = y
⇒ (x + 1)(x + 1) = y
⇒ (x + 1)² = y
y-intercept when x = 0:
(0 + 1)² = 1² = 1
Therefore, intercepts the y-axis at (0, 1)
x-intercept when y = 0
(x + 1)² = 0
x + 1 = 0
x = -1
Therefore, intercepts (touches) x-axis at (-1, 0)
X intercept is where the line crosses the x axis or where y=0
y intercept is where the line crosses the y axis or where x=0
x intercept
set y=0
4x-3y=12
4x-3(0)=12
4x=12
divide by 4
x=3
the x intercept is 3
y intercept
set x=0
4x-3y=12
4(0)-3y=12
-3y=12
divide by -3
y=-4
the y intercept is -4
x intercept: 3
y intercept: -4
answer is first one
Her niece sees 15 goats.
Step-by-step explanation:
Given,
Total animals on barn = 40
Total legs counted by May's niece = 110
A goat has 4 legs and chicken has 2 legs.
Let,
x represent the number of goats
y represent the number of chicken
x+y=40 Eqn 1
4x+2y=110 Eqn 2
Multiplying Eqn 1 by 4

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 2

Putting y = 25 in Eqn 1

Her niece sees 15 goats.
