Determine the x-intercept and y-intercept of the following linear equations

Blizzard [7]

Answer:

Step-by-step explanation:

the x intercept takes coordinate (x,0)

the y intercept takes coordinate (0,y)

x intercept y intercept

40: x+y=5 (5,0) (0,5)

x=0 , y=5, when y=0 x=5

41: x-y=5 (5,0) (0,-5)

x=0, -y=5 then y=-5, when y=0, x=5

42: 3x+4y=12 (4,0) (0,3)

x=0, 4y=12⇒y=12/4⇒y=3

y=0, 3x=12⇒x=12/3⇒x=4

43: 2x+3y=6 (3,0) (0,2)

x=0 , 3y=6⇒y=6/3=2

y=0 ,3y=6 ⇒ y=6/3 ⇒y=2

44: 3x+4y=-24 (-8,0) (0,-6)

x=0 , 4y=-24⇒y=-24/4 ⇒ y=-6

y=0 , 3x=-24⇒ x=-24/3⇒x=-8

45: 1/3x+2/3y=5/6 (5/2,0) (0,5/4)

x=0 , 2/3 y=5/6 ⇒12y=15 ⇒ y=15/12 ⇒y=5/4

y=0 , 1/3 x=5/6 ⇒6x=15 ⇒x=15/6 ⇒x=5/2

46: x=-2 (-2,0) no y intercept

it is vertical line , there is no y intercept

47: y=15 no x intercept (0,15)

horixzontal line, no x intercept

48: 3x-7y=8 (8/3,0) (0,-8/7)

x=0 , -7y=8 ⇒y=-8/7

y=0 , 3x=8 ⇒x=8/3

Which choice is true for a square?

liq [111]

Answer: A

Step-by-step explanation:

A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. ... A square however is a rhombus since all four of its sides are of the same length.

A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.

Find the measure of the arc or angle indicated. NO LINKS.

Advocard [28]

9514 1404 393

Answer:

10. A) 120°

11. D) 40°

12. D) 54°

13. A) 101°

Step-by-step explanation:

The applicable rules of angles and arcs are ...

the whole is the sum of the parts
arcs of a circle total 360°
an inscribed angle intercepts an arc of twice its measure

10) Angles C and L intercept the same arc (DE) so will have the same measure.

15x = 16x -4

4 = x . . . . . . . . add 4-15x

arc DE = 2(15x) = 30(4) = 120 . . . degrees

11) Arc VW is twice the measure of angle X, so ...

9x +8 = 2(5x)

8 = x . . . . . . . . . subtract 9x

∠VXW = 5x = 5(8) = 40 . . . degrees

12) Arc EFG is twice the measure of angle W, so ...

70° +FG = 2(88°)

FG = 106° . . . . . . . . . subtract 70°

Arc FGW is twice the measure of angle E, so ...

106° +GW = 2(80°)

GW = 54° . . . . . . . . . . subtract 106°

13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.

RS +ST +TR = 360°

119° +2(70°) +TR = 360°

TR = 101° . . . . . . . . subtract 259°

Answer:

Step-by-step explanation:

Hello,

$f(x) =\dfrac{ x^2+5x+6}{x+2}=\dfrac{(x+2)(x+3)}{x+2}=x+3$

no discontinuity point

zero = -3

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
