Answer:

19°

Step-by-step explanation:

m<A + m<B + m<C = 180°

a + 17° + 49° + 5a = 180°

6a + 66° = 180°

6a = 114°

a = 19°

Those two functions just miss each other so there are no real solutions. Every polynomial with complex coefficients has complex solutions.

$2x^2 + 2 = 3x$

$2x^2 - 3x = -2$

$2( x^2 - \frac 3 2 x) = -2$

$x^2 - \frac 3 2 x = -1$

$x^2- \frac 3 2 x+ (\frac 3 4)^2= -1 + (\frac 3 4 )^2$

$(x - \frac 3 4)^2 = -\frac 7{16}$

$x - \frac 3 4 = \pm \sqrt{ -\frac 7{16}}$

$x = \frac 3 4 \pm \frac i 4 \sqrt{7}$

$x = \frac 1 4(3 \pm i \sqrt{7})$

What is the solution for x in the equation. <br> 4x - 3+5 = 2x + 7 - 8x

FrozenT [24]

Answer:

hence solution for x in the equation is x= 1/2

Step-by-step explanation:

4x - 3+5 = 2x + 7 - 8x

4x +2 = -6x +7

taking x to the other side then we get

4x+6x = -2+7

10x = 5

divide both side by 10

10x/10 =5/10

x= 1/2

hence solution for x in the equation is x= 1/2

Giving that (4,-8) is on a graph of f(x) find the corresponding point for the function f(x+3)

VLD [36.1K]

When the adding is inside the parentheses it is a horizontal shift to the left.

This affects the x - axis.

So, we take our x coordinate, 4, and subtract 3.

4 - 3 = 1

So, the new point is:
( 1, -8)
