Answer:
The answer is (4x - 3)/(x + 6)
Step-by-step explanation:
∵ (4x² - 7x + 3)/(x² + 5x - 6)
Factorize the numerator:
4x² - 7x + 3 = (4x - 3)(x - 1)
Factorize the denominator:
x² + 5x - 6 = (x - 1)(x + 6)
∴ (4x - 3)(x - 1)/(x - 1)(x + 6) ⇒ reduce (x - 1) from in up and down
∴ The answer is (4x - 3)/(x + 6) ⇒ the fourth answer
So you would take the 360 cm and divide it by 2.5 cm or 1 inch to see how many inches the ceiling is.
360÷2.5= 144 inches
Answer:
Step-by-step explanation:
Answer: 720
Step-by-step explanation:
480 : 16 marked
480-16 = 464
They saw 464 unmarked squirrels and 16 marked squirrels
464/16 = 29
They saw 29 unmarked squirrels for every 1 makes squirrel
29 * 24 = 696
They would have seen 696 unmarked squirrels for the 24 marked squirrels.
696 + 24 = 720
1) To graph y = 2x +3, give 2 different value for x & find its related y value:
for instance if x = 0 , then y = 3
if x = 1, then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.
2) The inverse of y=2x+3
a) Switch the x & y ===> x=2y+3
b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y
c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y
And the inverse function of y = 2x+3 is y= 1/2(x+3)
