P has a y intercept of 6 and a slope of 1 up for every two to the right, 1/2

y = (1/2) x + 6

Q has a y intercept of -3 and a slope of 4 down from every one to the right, -4.

y = -4x - 3

For the solution we equate the two ys,

(1/2)x + 6 = -4x - 3

x + 12 = -8x - 6

9x = -18

x = -2

y = (1/2) (-2) + 6 = 5

Solution: (x,y)=(-2, 5)

Which step is incorrect when solving the equation 2(x+9)=4(x+7)+2?

iragen [17]

Answer:

3. 2x+18=4x+26

Step-by-step explanation:

2(x+9)=4(x+7)+2

2x+18=4x+28+2

2x+18=4x+30

The step that made an error in solving this linear equation is step 3.

Hope this helps ;) ❤❤❤

Rotate the one on the left to look like the one on the right.

BC = SP

AB = SR

AD = RQ

CD = PQ

A = R

B = S

C = P

D = Q

In circle K , diameter CD is drawn and point E is located on the circle such that CE=16 and DE=30 .What is the length of the rad

egoroff_w [7]

Answer:

The length of the radius of the circle K is $17\ units$

Step-by-step explanation:

we know that

The triangle CDE is a right triangle with the 90 degree angle at point E

Applying the Pythagoras Theorem

Find the length of CD (diameter of the circle K)

$CD^{2}=CE^{2}+DE^{2}$

substitute the values

$CD^{2}=16^{2}+30^{2}$

$CD^{2}=1,156$

$CD=34\ units$

Find the radius

Remember that the radius is half the diameter

$r=34/2=17\ units$
