The value of a is 26?! That's not a function tho?

Easy if you know the formula

all this means is that your x value is a, and when it is, will give you the value 26.

f(a) = 6a - 4 = 26

6a = 30
a = 5

Solve 2x2 − 12x + 20 = 0.<br><br> 3 ± i<br> 3 ± 2i<br> 1 ± 2i<br> 2 ± 3i

makkiz [27]

This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i

write the slope intercept form of the equation of the line with a slope of -2/5 that passes through 15, -9/2

Sever21 [200]

Answer:

The equation of line in slop-intercept form is y = $\dfrac{-2x}{5}$ + $\dfrac{3}{2}$

Step-by-step explanation:

Given as :

The slope of the a line = m = $\dfrac{-2}{5}$

The line is passes through points $x_1 , y_1$ = 15 , $\dfrac{- 9}{2}$

<u>According to question</u>

Equation of line in slope - intercept form

y - $y_1$ = m × ( x - $x_1$ )

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × ( x - 15 )

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × x - ( $\dfrac{-2}{5}$ ) × 15

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × x + 6

Or, y = $\dfrac{-2}{5}$ × x + 6 - $\dfrac{9}{2}$

Or, y = $\dfrac{-2}{5}$ × x + $\dfrac{12-9}{2}$

Or, y = $\dfrac{-2}{5}$ × x + $\dfrac{3}{2}$

So, The equation of line in slop-intercept form y = $\dfrac{-2}{5}$ × x + $\dfrac{3}{2}$

Hence, The equation of line in slop-intercept form is y = $\dfrac{-2x}{5}$ + $\dfrac{3}{2}$ Answer

A=area

H=2b+4

A=1/2 bh

A=(1/2)(2b+4)b

(1/2)(2b+4)b<=168

Or
