Answer:

y-9= -4(x+1)

Step-by-step explanation:

First, you should know what the format for point slope form is. y-y1=m(x-x1). Now, fill in the points to the x1 and y1 variables. It doesn't matter what ordered pair you use. If the number you fill in is negative, for example, -1, change it to a positive 1. If you're plugging in a positive number such as 9, it becomes -9. Now, it may look like this: y-9=m(x+1). However, you still need to find slope. You can use the expression y-y1/x-x1. 9-1=8. -1-1= -2. So, your slope is 8/-2. However, you can simplify this to -4. Now, plug in -4 to your equation to have your final answer: y-9=-4(x+1).

Show me how to solve 4.2÷0.6 using base 10 blocks
allochka39001 [22]

Answer:

7

Step-by-step explanation:

We are to solve 4.2÷0.6 using base 10 blocks

4.2 = 42/10

0.6 = 6/10

4.2÷0.6

= 42/10 ÷ 6/10

= 42/10 * 10/6

= 42/6

= 7

Hence the required expression using base 10 block is 7

Roy’s Used Cars has 12 trucks, 20 cars and 15 SUV’s on the lot. If the Roy randomly gives away a vehicle to some lucky customer,
malfutka [58]
<h2>Answer:</h2><h2>The probability that Roy gives randomly an SUV = 15 / 47</h2>

Step-by-step explanation:

The total number of used cars owned by Roy = 47

[12 trucks + 20 cars + 15 SUV = 47 cars]

The total number in sample space, n (S) = 47

The probability that Roy is giving away and SUV = ?

Let A be the event that Roy is giving an SUV

Total no of SUV's , n (A) = 15

The probability of giving an SUV, P (A) = n (A) / n (S)

                      P (A)  = 15 / 47

Given: Tangents <br> LA<br> and <br> LB<br><br> m∠AOB=110°<br> Find: m∠ALO.
Sonbull [250]

Answer:

m<ALO=35°

Step-by-step explanation:

we know that

The right triangle AOL is congruent with the right triangle BOL

because

OA=OB=radius of the circle

OL is a common side

LA=LB ---> by applying the Pythagoras theorem

therefore

m<AOL=m<AOB/2

m<AOL=110°/2

m<AOL=55°

Remember that

m<AOL+m<ALO=90° ------> by complementary angles

m<ALO=90°-55°=35°
