The numerical value of the expression (6x² - 4x - 7) when x =2 is 9

<h3>What is the numerical value of the expression when x=2?</h3>

Given the expression in the question;

6x² - 4x - 7

x = 2

To determine the numerical value of the expression when x =2, replace all the occurrence of x with 2 in the expression and simplify.

6x² - 4x - 7

6(2)² - 4(2) - 7

24 - 8 - 7

24 - 15

9

Therefore, the numerical value of the expression (6x² - 4x - 7) when x =2 is 9

avanturin [10]

Hey there!

-4.36 + 1.2 [2.8 +(-3.51)]

= -4.36 + 1.2(2.8 - 3.51)

= 4.36 1.2(-0.71)

= -4.36 - 0.852

= -5.212

Therefore, your answer is: -5.212

Good luck on your assignment and enjoy your day!

So it is an isosceles triangle that means that the bottom two angles are equal...
so 
40 = 5x 
divide both sides by 5 and you get 8

now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40

You are correct!!! :)

Start your dot on 3 on the y axis. Move is downwards on the y axis by 5 everytime you move over once on the x axis. Shade all the stuff above the line since it says y is greater than -5x+3
