The big desk in your boss's office is 75 inches long. How long is that in feet?

masya89 [10]

Answer:

The big desk in your boss's office is 6.25 feet long.

Step-by-step explanation:

As given

The big desk in your boss's office is 75 inches long.

As the relationship between inches and feet.

As 1 feet = 12 inches

$1\ inches = \frac{1}{12}\ feet$

Now convert 75 inches into feet.

$75\ inches = \frac{75}{12}\ feet$

$75\ inches = 6.25\ feet$

Therefore the big desk in your boss's office is 6.25 feet long.

Graph the equation<br> y=-2x+1

Fofino [41]

Start by plotting the y-intercept at (0,1).

From that point, count "up 2, right 1" to get a second point on your graph.

If needed repeat that "up 2, right 1" from that second point to get a third point.

Draw the line that connects these 2 or 3 points.

Solve x2 – 8x + 15 < 0.<br><br> Select the critical points for the inequality shown.

quester [9]

Answer:

x=3,5

Explanation:

x2−8x+15=0

Try to express the terms of the equation in square form.

Adding 16 both sides of the equation,

(x2−2⋅x⋅4+42)+15=16

or,(x−4)2+15−16=0

or,(x−4)2−1=0

or,(x−4)2−12=0

This is the a2−b2=(a+b)(a−b)form.

(x−4+1)(x−4−1)=0

or,(x−3)(x−5)=0

Now, equate both the terms to zero since both of them when multiplied, give zero.

Either,

x−3=0

∴x=3

Or,

x−5=0

∴x=5

Ans:x=3,5 Hope this helpsXD...!!
