Evaluate the expression when x=3 and y= -2

Mathematics
1 answer:
Paul [167]4 years ago

Answer:

-11

Step-by-step explanation:

To evaluate an expression with variables, replace the variables with what the question tells you to.

Replace "x" with 3. Replace "y" with -2.

-x + 4y

= -(3) + 4(-2)       Multiply 4 and -2 first to get -8

= (-3) + (-8)         Add normally. -3 + (-8) is the same as (-3) - 8.

= -11             Answer

Therefore the solution is -11.

How many times larger is 4x10^7 than 5x10^5
irina1246 [14]

Answer:

8 times larger

Step-by-step explanation:

4 · 10^{7} = 4 · 10 · 10 · <u>10</u> · <u>10</u> · <em>10</em> · <em>10</em> · 10

4 · 100 · <u>100</u> · <em>100</em> · 10

400 · 10000 · 10

= 40000000

5 · 10^{5} = 5 · 10 · 10 · <u>10</u> · <u>10</u> · 10

50 · 100 · <u>100</u> · 10

5000 · 1000

= 5000000

40000000 ÷ 5000000 = 8

Answer:

<em>( About ) 1.77 seconds; Option B</em>

Step-by-step explanation:

We are given the equation h ( t ) = - 16t^2 + 50, so in order to determine the time let us determine the x - intercept for y ⇒ 0;

- 16t^2 + 50 = 0,

- 16t^2 = - 50,

t^2 = 25 / 8,

Thus t ⇒ √ ( 25 / 8 ), and t ⇒ - √ ( 25 / 8 ),

t ⇒ ( 5√2 )/ 4, and - ( 5√2 )/ 4,

But time is represented only by a positive value, thus

t ⇒ ( 5√2 )/ 4 = 1.767766953......., ( About ) 1.77 seconds

<em>Answer; ( About ) 1.77 seconds; Option B</em>
