If x= -2 and y=√12 then 2(3x³+ 2y²)=

Mathematics

Illusion [34]1 year ago
7 0

Answer:

Step-by-step explanation:

Begin by filling in x as -2 and y as √12 in the given expression:

2(3(-2)^3+2(\sqrt{12})^2).  Work inside the parenthesis first and deal with those exponents:

(-2)³ is the same as (-2)(-2)(-2) which is -8;

(√12)² is the same as (√12)(√12) which is √144 which is 12.

Filling those simplifications in:

2(3(-8)+2(12))=2(-24+24)=2(0)=0

Substitution method of y=x+5 and 5x+y=3
Levart [38]
To solve by substitution, you need to fill in the value for either x or y. Since y = x + 5, you already have the y value. It's x + 5. Now you need to find x before you can go any further. So let's take 5x + y = 3 and fill x + 5 in for y. 5x + y = 5 5x + x + 5 = 3 Now solve for x. 5x + x + 5 = 3 6x + 5 = 3 6x = 3 - 5 6x = -2 x = -2/6 or -0.33 Now solve x + 5 for y. y = x + 5 y = -0.33 + 5 y = 4.67 So x = -0.33 and y = 4.67

The compound inequality 8.00 ≤ x &lt; 9.50 represents all values, x, for which college students are paid hourly as teacher assis
Orlov [11]

Answer: x≥ 8.00 and x < 9.50 is the correct option.

Step-by-step explanation:

Since, given expression 8.00 ≤ x < 9.50

Where x is the value for which college students are paid hourly as teacher assistants.

so, x is greater than or equal to 8.00

Therefore, x\geq 8.00  

And, x is less than 9.50

Therefore,  x < 9.50

On combining both expression we get,  x\geq 8.00 and x < 9.50.

Thus, Third Option is correct.
