Answer:

Instead of moving the 3x to the opposite side of the equation they moved the 2x. And the correct answer is x=-6 not x=6.

Step-by-step explanation:

Student Work:

2(x + 4) – 8 = 3x+10-4

2x + 8–8 = 3x + 6

2x = 3x + 6

- 3x – 3x

X = 6

My work:

2(x+4)-8=3x+10-4

2x+8-8=3x+6

2x=3x+6

-x=6

x=-6

Can a chord also be classified as a radius?
klemol [59]
No.

A chord is a straight segment that joins two points of the circumference. It starts at a point in the circumference and ends at other point in the circumference.

The radius goes from the center of the circle (which is not on the circumference) to one point of the circumference.

The diameter is a chord (the largest chord possible); but not the radius.

which function rule is represented by the tablex 0 1 2 3y 0 -7 -14 -21a y= 7xb y= -7xc y= x-8d y= 7x-14
salantis [7]

The answer is y = -7x

Expalnation

Two points on the table are (0,0) and (1,-7)

Change in y = -7-0 = -7

Change in x = 1-0 = 1

Slope m of the function = -7/1= -7

Using y= mx + c

Picking point (0,0), x = 0, y = 0

y = mx + c becomes

0 = -7(0) + c

0 = 0 + c

c= 0

Hence, the equation is y = -7x + 0

which is y = -7x

Option b is the correct answer

F(x)=3^2-2and g(x) =4x+2 what is the value of (f+g)(2)
morpeh [17]

Step-by-step explanation:

f(x) =  {3}^{2}  - 2 = 9 - 2 = 7 \\ g(x) = 4x + 2 \\  \therefore \: (f + g)(x) = 7 + 4x + 2 \\  \therefore \: (f + g)(x) =  4x + 9 \\ \therefore \: (f + g)(2) =  4 \times 2 + 9 \\ \therefore \: (f + g)(2) =  8 + 9 \\  \red{\boxed{ \bold{ \therefore \: (f + g)(2) =  17}}}
