State whether the value for the unknown makes inequalities 74/e < 12

Mathematics

Answer:

Yes

Step-by-step explanation:

74/e < 12

Since e is in the denominator, e can not be 0.

If e > 0,

74/e < 12

74 < 12e

e > 74/12

e < 37/6

If e < 0,

(When you multiply by e, which is a negative value, inequality reverses)

74 > 12e

e < 74/12

e < 37/6

Answer:

37/6 < e or e<0

Step-by-step explanation:

74/e < 12

Multiply each side by e

74/e *e < 12*e

74 <12e

Divide each side by 12

74/12 <12e/12

37/6 < e

If e is less than 0, the inequality will flip

74/e *e > 12*e

Divide each side by 12

74/12 >12e/12

37/6 > e

But we limited it to less than 0

0 >e

Answer:

Linear: greater than 2011

Quadratic: lesser than 2011

Cubic: lesser than 2011

Step-by-step explanation:

At x = 2

Linear regression equation:

y = -6777.54(2) + 110001.04

y = 96445.96

More than 2011

Quadratic: y = -251.10(2)² - 2760.02(2) + 98618.06

y = 92093.62

lesser than 2011

Cubic: y = -6.23(2)² - 101.67(2)² - 3747.49(2) + 100142.23

y = 92190.73

lesser than 2011

Help me with #5 pleaseeeeeeeeeee

Answer:

\angle 1 = 45 degrees

Step-by-step explanation:

Sum of 3 angles in a triangle is 180..

The angles given are:

60

7x + 12

1

So we sum to 180 and write:

60+7x+12+\angle 1=180\\72+7x+\angle 1=180\\7x+\angle 1=108

Also, straight angle is 180 degrees, thus Angle 1 and (14x + 9) angle is sum to 180, thus we can write:

14x+9+\angle 1=180\\14x + \angle 1=171

Or we can write this as:

14x + \angle 1=171\\\angle 1 = 171 - 14x

We substitute this expression for Angle 1 into 1st equation we got and solve for x first,

7x+\angle 1 = 108\\7x+( 171 - 14x)=108\\-7x=-63\\x=9

Since x = 9, the angle "14x + 9" would be:

14(9) + 9 = 135

Hence Angle 1 would be:

\angle 1 + 14x + 9 = 180\\\angle 1 + 135 = 180\\\angle 1 = 45
