Answer:

y = 5x + 12

Step-by-step explanation:

Use the formula: y - y1 = m(x - x1)

Plug in all numbers into your equation: y - 7 = 5(x - -1)

Minus with a minus becomes a positive: y - 7 = 5(x + 1)

Distribute:                    y - 7 = 5x + 5

Add 7 to both sides:      +7          +7

Answer: y = 5x + 12

Find m angle d for m angle b = 65<br> The figure is not drawn to scale
Aleksandr [31]

Answer:

Denote O as center of circle, draw OA, OC.

As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):

=> AOC + D = 180

Moreover, angle  AOC = 2 x angle B = 2 x 65 = 130

=> D = 180 - 130 = 50 deg

Hope this helps!

Under the last-in, first-out (LIFO) inventory valuation method, a price index for inventory must be established for tax purposes
frosja888 [35]

Answer:

The laspeyres method of weighted aggregate price index is used of LIFO inventory valuation, therefore laspeyres index number is 106.08

Step-by-step explanation:

First of all we would have to perform the following table:

                                             

Product   Ending Inventory(Q0)  Begining(P0)   Ending(P1)   P0×Q0   P1×Q0  

    A                    500                         0.15               0.21                75        105

    B                       50                         1.60               1.80                 80         90

    C                       100                        4.50             4.20                 450      420

    D                       40                          12.00          13.40                 480     536

                                                                                             Total  1085     1151

Therefore, using laspeyres index number, we calculate the following:

laspeyres index number=(∑P1×Q0/∑P0×Q0)×100

laspeyres index number=(1151/1085)×100

laspeyres index number=106.08

Solve for x: 6 x2 + 2x - 3 2 = 0
Zigmanuir [339]

I think the answer is 10 because:

6x2=12

12+2x-32=0

make the like terms together = 12-32+2x=0

= -20+2x=0

again make the like terms together = 2x=0+20 [sign changes when it goes to the other side]

so, 2x=20

x=20/2 [ multiplication will change into division when it goes to the other side]

therefore x=10
