The answer is A.) -5..because you plug 3 into the x so it would be -2(3)+1 and -2(3) is -6 and then add one and you get -5

C. 3

Step-by-step explanation:

You know the angle sum is ...

∠FGT +∠TGH = ∠FGH

You can use this relation with the given values to find x.

90 + (8x +4) = 39x +1

93 = 31x . . . . . . . . . . . . . add -1-8x, collect terms

A) The person that has a greater probability of selecting a quadrilateral is Robert.

B) The person that has a greater probability of selecting a polygon is; Robert.

C) The event that is more likely to happen is the Probability of Sandy selecting a polygon with at least 2 sides parallel.

<h3>How to Identify Polygons?</h3>

Sandy has; Square, Rhombus, Equilateral Triangle, Regular Hexagon

Robert has Scalene Triangle, Kite, Right Isosceles Triangle, Isosceles Trapezoid, Quadrilateral.

A) Sandy's probability of selecting a quadrilateral = 2/4 = 0.5

Robert's probability of selecting a quadrilateral = 3/5 = 0.6

The person that has a greater probability of selecting a quadrilateral is Robert

B) The person that has a greater probability of selecting a polygon is; Robert because he has more.

C) Probability of Sandy selecting a polygon with at least 2 sides parallel is; 3/4 = 0.75

The Probability of Robert selecting a polygon with at least 2 sides parallel is; 2/5 = 0.4

The event that is more likely to happen is the Probability of Sandy selecting a polygon with at least 2 sides parallel.

Identify the x-intercept and y-intercept of the equation below.

Radda [10]

Answer:

x intercept at (7/3 , 0)

y intercept at (0,-3)

Step-by-step explanation:

9x-7y=21

we need to find x and y intercepts

To find x intercept , plug in 0 for y

9x - 7(0) = 21

9x = 21

divide by 9 on both sides

x= 21/ 9 = 7/3

so x intercept at (7/3 , 0)

To find y intercept , plug in 0 for x

9(0) - 7(y) = 21

-7y = 21

divide by -7 on both sides

y= -3

so y intercept at (0,-3)
