Fed [463]4 years ago
3 0

Answer:

\text{B. }26}

Step-by-step explanation:

Since \overline{PN} and \overline{PQ} are equal, we can set them equal to each other:

7x+5=10x-4,\\9=3x,\\x=3

Substitute x=3 to solve for \overline{PQ}:

\overline{PQ}=10(3)-4=\boxed{\text{B. }26}}

Simplify.<br><br><br><br> A.<br> –28xy<br><br> B.<br> –28<br><br> C.<br> 28xy<br><br> D.<br> 27
Evgen [1.6K]

Your attachment says:            (-1/2) · (4x) · (-2) · (7y) · (-1)

Let's put together the
1st, 3rd, and 5th factors:        (-1/2) · (-2) · (-1)  =  -1

So now we have                      (-1) · (4x) · (7y)

Well                                           (4x) · (7y)  =  (4 · 7) · (x · y)  =  28 · x · y

So all together we have          (-1) · (28 · x · y)  =  -28xy

10) The line FG is a diameter of the circle with centre C (6, 1). Given F is (2.-3), find the coordinates of G.​
Maurinko [17]

Answer:

Coordinates of the endpoint g is (10,5)

Step-by-step explanation:

The coordinates of a midpoint can be found using the formula;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

In this case, we have the mid point but we want to get the end point

Thus;

(6,1) = (x1 + 2)/2 , (y1-3)/2

x1 + 2 = 2(6)

x1 + 2 = 12

x1 = 12-2

x1 = 10

y1 - 3 = 2(1)

y1 -3 = 2

y1 = 2 + 3

y1 = 5

The coordinates of G are (10,5)

Evaluate f(-2) for f(x)= 8x^2-7x+3
prisoha [69]

Answer: 49

Step-by-step explanation:

We know, x = -2

Substituting value of x in 8x^{2} -7x+3,

8(-2)^{2} - 7(-2) + 3\\=8(4) -7(-2) + 3\\=32+14+3\\=49
