Point slope form is y-y1=m(x-x1)

Since we have to write the equation of a perpendicular line we will have to use the slope that is opposite and reciprocal.

y - (-1) = - \frac{1}{5} (x - (-2))
y + 1 = - \frac{1}{5} (x + 2)

Hope this helps :)

The value of a and b
Jlenok [28]

Answer:

Both a and b would both equal 45 degrees

Step-by-step explanation:

To find this, we need to note that a and 135 create a straight line. Since a straight line has 180 degrees, we can create an equation to solve for a.

135 + a = 180

a = 45

Now that we know a is equal to 45, we can tell that b is also equal to that amount. This is because two parallel lines cut by a transversal creates the same angle.

3² +4² = 5²,
AlekseyPX

Answer:

They are all true

Step-by-step explanation:

1. 3² +4² = 5²

3x3 + 4x4 = 5x5

  9   +  16  =  25

25 = 25

-----------------------

2. 6² + 8² = 10²

36 + 64 = 100

100 = 100

------------------

3. 9² + 12² = 15²

81 + 144 = 225

225 = 225

-------------------

4. 5² +12² =13²

25 + 144 = 169

169 =169

-------------------

a truck weighs 5,400 pounds. An open-wheel race car weighs 1/4 as much. how much does the race car weigh
gtnhenbr [62]
Since 1/4 is equal to 0.25 than you would do 5,400 times 0.25 and get the answer of 13,500.0. So the race car weighs 13,500 pounds.

Magaldi is constructing its cash budget. Its budgeted monthly sales are $20,000, and they are constant from month to month. 60%
iogann1982 [59]

Answer:

$5,820

Step-by-step explanation:

The average net cash flow during the month is total cash receipt minus total payments.

Cash receipt on the month's sales=60%*$20,000*98.5%=$11820

60% cash received ,the 98.5% is after cash discount of 1.5%

cash receipt from previous month sale=40%*$20,000=$8,000

Payment for purchases=$20,000*40%=$8,000

payment for wages,rent and taxes=$20,000*30%=$6000

Total cash inflow=$11,820+$8,000=$19820

total cash outflow=$8,000+$6,000=$14,000

average net cash flow=$19,820-$14,000=$5,820
