Answer:

x = 90
y = 64

Step-by-step explanation:

If we take the arcs to mean that those angles are congruent, then the sum of exterior angles is ...

x° +2y° +75° +67° = 360°

y = 109 -x/2 . . . . . . subtract non-x terms and divide by 2

Because x° forms a linear pair with a right angle, we know ...

x° = 180° -90° = 90°

Then ...

y = 109 -90/2 = 64

The values of x and y are 90 and 64, respectively.

Answer:

Angle 1 = 35

Angle 2 = 70

Angle 3 = 75

Step-by-step explanation:

Let's define Angle 1 as <em>x</em>

<em />

Angle 1 = x

Angle 2 = 2x

Angle 3 = 2x + 5

x + 2x +2x + 5 = 180

5x + 5 = 180

5x = 175

x = 35

Angle 1 = 35

Angle 2 = 70

Angle 3 = 75

What is the simplified form of this expression (-3x^2+4x)+(2x^2-x-11)

zlopas [31]

Answer:

SolutioN :

$\bf \: \star ( - 3x^{2} + 4x) + (2 {x}^{2} - x - 11)$

$\longrightarrow \bf \: - 3 {x}^{2} + 4x + 2 {x}^{2} - x - 11$

$\longrightarrow \bf \: - 3 {x}^{2} + 2 {x}^{2} + 4x - x - 11$

$\longrightarrow \boxed{\bf \: - {x}^{2} + 3x - 11}$

What is the graph of y= 3/4x - 3

alexira [117]

-3 is the y intercept, so place a point there. The slope is 3/4. So from your -3 point, go up 3 and over 4. Make a point. Do that another time and also from the -3 intercept go down 3 and over left 4, the. you’ve got yourself a nice line.

The quadratic equation 2x^2+4x-30=0 has two solutions. one of the solutions is x=3 the other solution is?

BartSMP [9]

Answer:

2x^2+4x-30=0

Step-by-step explanation:

2x^2+10x-6x-30=0

2x(x+5)-6(x+5)=0

(2x-6)(x+5)=0

2x-6=0 x+5=0

x=6/2 x=-5

x=3
