3 x-intercepts:

1) x = -1
2) x = 3
3) x = 4

Answer:

x-intercept states that the graph crosses the x-axis.

i.,e substitute y=f(x)= 0 and solve for x;

Given the function: f(x) = (x+1)(x-3)(x-4)

By definition of f(x)

Substitute f(x) =0 and solve for x;

(x+1)(x-3)(x-4) = 0

By zero product property: if ab = 0 then either a = 0 or b =0

x+1 = 0 ,    x-3 =0    and  x-4 = 0

⇒ x = -1 , 3 and 4

therefore, the number of x-intercepts are 3

At the ice cream parlor,sundaes cost $4.25 and waffle cones cost $3.75.You and your friends have $50 to spend.Your group buys 5
stich3 [128]

Answer:

You can buy 7 waffle cones.

Step-by-step explanation:

Let sundae = x

Let waffle cones = y

4.25x + 3.75y ≤ 50

4.25 (5) + 3.75y ≤ 50

21.25 + 3.75y ≤ 50

3.75y ≤ 28.75

y ≤ 7.666666666

* round to the nearest whole to get 7

The hypotenuse of a right triangle is twice the length of one of its legs. The length of the other leg is three feet. Find the l
aliya0001 [1]

a^2 + b^2 = c^2

Let c = hypotenuse = 2x

One of the legs = x. Let a or b = x.

I will let a = x. We can then say that b = 3.

3^2 + x^2 = (2x)^2

9 + x^2 = 4x^2

9 = 4x^2 - x^2

9 = 2x^2

9/2 = x^2

sqrt{9/2} = sqrt{x^2}

3/sqrt{2} = x

Rational denominator.

[3•sqrt{2}]/2 = x = a

Side 3 is given to be 3 feet. So, b = 3.

Hypotenuse = 2x

Hypotenuse = 2([3•sqrt{2}]/2)

Hypotenuse = 3•sqrt{2}

Understand?

The three sides are 3, [3•sqrt{2}]/2 and

3•sqrt{2}.
