- 2x – 5 < 12<br> Yo help

Elina [12.6K]

Answer:

x > -17/2

Step-by-step explanation:

Step 1: Write inequality

-2x - 5 < 12

Step 2: Solve for <em>x</em>

<u>Add 5 to both sides:</u> -2x < 17

<u>Divide both sides by -2:</u> x > -17/2

Here, we can see that any number greater than -17/2 would work, so x could equal 01234718905731857013570 if we wanted it to, as long as it is greater than -8.5.

Write the equation using function notation f(x). then find f(0)<br><br> 2x^2 - 3y = 6

Grace [21]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: f(0) = -2$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: 2 {x}^{2} - 3y = 6$

$\qquad \tt \rightarrow \: 3y + 6 = 2 {x}^{2}$

$\qquad \tt \rightarrow \: 3y = 2 {x}^{2} - 6$

$\qquad \tt \rightarrow \: y = \cfrac{2 {x}^{2} - 6 }{3}$

$\qquad \tt \rightarrow \: y = \cfrac{2 {}^{} }{3} {x}^{2} - 2$

[ here, y can be replaced with f(x) because y is a function of x ]

$\qquad \tt \rightarrow \: f(x) = \cfrac{2 {}^{} }{3} {x}^{2} - 2$

$\large\textsf{Find f(0):}$

$\qquad \tt \rightarrow \: f(0) = \cfrac{2 {}^{} }{3} {(0)}^{2} - 2$

$\qquad \tt \rightarrow \: f(0) = 0 - 2$

$\qquad \tt \rightarrow \: f(0) = - 2$

Find the solution of the system of equations. 3x-8y = 19<br>3x + 5y = -46<br>

sattari [20]

(-7,-5)

Step-by-step explanation:

3x-8y = 19

minus

3x + 5y = -46

0x - 13y = 65

- 13y = 65

÷-13

y = - 5

Substitute y = - 5 into one of the functions:

3x-8y = 19

-8 x - 5 = 40

3x + 40 =19

-40

3x. = - 21

÷3

x= - 7

Solution is (-7,-5)

Hope this helps!

The average of six numbers is 4. If the average of two if those numbers is 2,what is the average of the other 4 numbers?

harina [27]

Answer: Average of other 4 numbers =5

Step-by-step explanation:

Sum of n numbers = Average of n numbers x n

Given: Average of 6 numbers =4

so sum of 6 numbers = 6x 4 = 24

Average of 2 numbers = 2

Sum of 2 numbers = 2 x 2 =4

Sum of rest of 4 numbers = sum of 6 numbers - Sum of 2 numbers

= 24-4

=20

Average of 4 numbers = $\dfrac{20}{4}$

i.e. Average of 4 numbers =5
