Choose all the equations that are true if y = 6.

Mathematics
1 answer:
Anni [7]3 years ago
7 0

Answer:

The first and third.

Step-by-step explanation:

For the first one, you just subtract 52.37 and 46.37 and the answer is 6, so that makes the equation 6=y, which is right. The second one equals 6.75, so that's not what we need. For the third one, you divide by 8 on both sides to isolate y, and that results in y=6, which is right. For the fourth one you subtract by 3.2 on both sides to isolate y and that results in 5.8, which isn't what we need. I think for the last one you meant to type y=4+24, in which case that would be y=28, which isn't what we need.

Answer:

x=50

Step-by-step explanation:

Because these angles are vertical, they are equal. Let’s find x.

3x+12=162

3x=150

x=50

So, x=50.

Write the equation of the line that passes through (–1, 5) and has a slope of 3 in point-slope form.
Mama L [17]

The point-slope form:

y-y_1=m(x-x_1)

We have:

(-1,\ 5)\to x_1=-1,\ y_1=5\\m=3

Substitute:

y-5=3(x-(-1))\\\\y-5=3(x+1)

Answer: C. y - 5 = 3(x + 1)

An electric company has to track on-time payments and late payments for each customer monthly. It is impossible for a customer t
OLga [1]

Answer:

The  probability that a customer pays late each month is    P(B)  =  0.27

Step-by-step explanation:

Let     P( A ) be the probability that the customer pays on time and the value is  0.55

Let  P( B )  be the  probability that a customer pays late each month

So

  The probability that a customer pays late or on-time each month  is  P(A u B) and  the value is  0.82

The probability that a customer pays on-time and late each month is  P(A n B) and  the value is  zero ( 0 ) given that it is impossible

   Now The probability that a customer pays late or on-time each month  is mathematically represented as

      P(A u B)  =  P(A) +  P(B)  -   P(A n B)

=>     0.82  =  0.55 + P( B ) -   0

=>    P(B)  =  0.27
