Answer: y=3

Explanation: In slope-intercept form if a variable is 0 you leave it out so really this equation is y=0x+3 but the 0 cancels out the x, so you're left with y=3

Determine the maximum number of zeros. Then, determine the x-intercepts of the function. x^3-3x^2-22x+24

JulijaS [17]

Answer:

Three zeros $x=-4,\ x=1,\ x=6$

x-intercepts: (-4,0), (1,0), (6,0)

Step-by-step explanation:

Plot the graph of the function $y=x^3-3x^2-22x+24$ on the coordinate plane. This graph intersects the x-axis at three different points (see attached diagram):

(-4,0);
(1,0);
(6,0).

This means $x=-4,\ x=1,\ x=6$ are zeros of the function $y=x^3-3x^2-22x+24$

The answer is t ≤ 11.

Subtract 10 from each side.

21 - 10 ≥ t + 10 - 10
t ≤ 11

Mark cast a shadow that is 4 feet long. At the same time, a nearby tree casts a shadow that is 20 feet long. If mark is 6 feet t

Trava [24]

Answer:

30 ft

Step-by-step explanation:

We can use the given information to set up a ratio...

$\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}$

$\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}$

We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):

120 = 4x

Divide both sides by 4

x=30 ft

Solve (2x-1/4)+(x/3)=2 Please provide a step by step with explanation

andrew11 [14]

Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7
