Write the equation of a line with a slope of -7/2 passing through the point 2,-4

Answers

Answer 1

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3

if you need to factor the equation the answer is : (x-6) (x-5)

Solve for
2x - 5 = 6
a. X= %
b. X = 11/2
C. X = 9
d. X = 6
Do u divide by 6

Answers

it would be B. add 5 to both sides, then it would be 2x=11. then divide by 2 to both sides. the most simplified answer is 11/2 i’m pretty sure.

Over which interval on the x-axis is there a negative
rate of change in the function?
O-2 to -1
O -1.5 to 0.5
O 0 to 1
O 0.5 to 1.5

Answers

There is a negative rate of change in the function In the interval (-2,-1) on the x-axis.

What is the average rate of change between two coordinates?

The slope of the straight line connecting two points is the average rate of change between those two coordinates.

We can infer from the graph,

the slope of the straight line connecting these points is negative in the range of -2 to -1.

As a result, the function's rate of change over this interval is negative.

Hence, In the interval –2 to –1 there is a negative rate of change in the function.

Answers

Answer:

Step-by-step explanation:

Since this is a test/homework, I'll give you a hint.

For a linear graph, if you took a ruler, and traced the "dots", it should always be in a straight line.

Another way, is finding a pattern. I can't really explain this so much, since it's fairly basic. Just find two dots, and see if they are similar in any way. If they are, good job! Find another. If their isn't, maybe try searching for another.

The third way: You could use the equation mx+b=y, but this is just a bit ridiculous for this problem, since you could just eye it.

Answers

Answer:
Assuming you're referring to the sides of a right triangle, the missing side X would be 12.
Step-by-step explanation:
The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. [tex]13^{2}[/tex] is 169, [tex]5^{2}[/tex] is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.

Find the length of the missing side. Simplify all radicals.

Answers

Answer:
b = 9√5 (see below)
Step-by-step explanation:
Using the Pythagorean Theorem, you can find the missing side. The two sides connect to the right angle are the legs, and the sloping side across from the right angle is the hypotenuse.
We know that:
a² + b² = c²
—where a and b are legs and c is the hypotenuse.
Plug in the known values:
a² + b² = c²
18² + b² = 27²
324 + b² = 729
b² = 405
√b² = √405
b = √81 √5
b = 9√5

Answer:
20
Step-by-step explanation:
A^2+B^2=C^2
18^2+B^2= 27^2
324+B^2= 729
-324 -324
B^2 = 405
B= [tex]\sqrt{405)\\[/tex]
B=20

The test will cover 120 pages in his textbook. He has read only 36 pages. If he plans to read an equal amount every day of the week to finish the 120 pages, how much must read each day?

Answers

Answer:
He must read each day=12 pages
Step-by-step explanation:
We are given that
Total number of pages in textbook=120
He has read number of pages=36
Number of days in a week=7
We have to find the number of pages read each day to finish 120 pages in a week.
Number of pages remaining for reading=120-36
Number of pages remaining for reading=84
Now,
Number of pages read each day=[tex]\frac{84}{7}[/tex]
Number of pages read each day=12
Hence, he must read each day=12 pages
