write the point-slope equation of the line that passes through(3,5) and (7,1)

Answer:

Step-by-step explanation:

1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.

2) If you meant X^2+12x=40:

a) Take half of the coefficient of x:  that would be (1/2)(12), or 6.  

b) Square this result, obtaining:  6² = 36

c) Add this 36 to x^2 + 12x + 40, and then subtract it:  We get:  

x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76

We have to add 36, as indicated above, to "complete the square."

Answer:

33 is 83% of 40.

Step-by-step explanation:

33/40 = 0.825

0.825 equals 82.5%

82.5% rounded is 83%.

I hope this helps!

The required value of percentage is 82.5%. Here, 33 represents approximately 82.5 percent of the total value of 40.

To find the percent, we need to determine what portion of 40 is represented by 33. We can set up a proportion to solve this problem.

Let x represent the unknown percentage.

We can set up the proportion:

33/40 = x/100

To solve for x, we can cross-multiply and then divide:

= (33 × 100) / 40

= 3300/40

Apply division operation to get:

= 82.5

Therefore, 33 is 82.5 percent of 40.

This means that 33 is equivalent to 82.5 percent of 40.

Answer:

a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8x = 32

b) Nina delivered 4 times as many papers the second week as the first week

Step-by-step explanation:

From the question, we are told that:

Nina delivers newspapers.

In the first week, she delivers 8 papers.

In the second week, she delivers 32 papers.

Let x represent the number of times

The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8paper × x = 32 papers

8x = 32

Solving for x

8x = 32

x = 32/8

x = 4 times

Therefore, Nina delivered 4 times as many papers the second week as the first week

Answer:

16

Step-by-step explanation:

If x = 3 and  , y = 2.  

2 x 3 = 6  and 5 x 2 = 10.

10 + 6 = 16

The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

We have to determine, the value of the expression 2x + 5y when x = 3 and y = 2.

According to the question,

Expression; 2x + 5y

To determine the value of the expression calculation must be done in a single unit following all the steps given below.

The value of expression 2x+5y,

When the value of x = 3 and y = 2,

Therefore,

[tex]= 2x + 5y[/tex]

Substitute the value of x = 3 and y = 2 in the given expression,

[tex]= 2(3)+ 5(2)\\\\= 6 + 10\\\\= 16[/tex]

Hence, The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

The slope is -4/5. Hope this helps!

Step-by-step explanation

To find the slope- Look at both points, Count how many units it is from the other point. Count how many units down and how many units right. Then its rise over run. So how many units down would go ontop of how many units right. This means the answer should be -4/5
