which equation is perpendicular to y= -2x + 5 ?

A) y= -2x -5
B) y= 2x -3
C) y= 1/2x -2
D) y=-1/2x+1

Answers

Answer 1
Ok so in order for the equation to be perpendicular, the slope have to be opposite of each other.

The original equation had -2 as the slope. The opposite of -2 is 1/2.

When the number is negative, the opposite of it is positive.
And in order for them to be completely opposite, you have to flip the number. So 2 turned into 1/2, since the denominator of 2 is 1.

And so since the opposite slope is 1/2, C is the correct answer.

which one is greater 3/40 or 7.5%

Answers

Answer: they are equal

To write a fraction as a percentage the easiest method is if we can change the denominator to 100.

#3/40 xx2.5/2.5 = 7.5/100 = 7.5%#

In many cases that method does not work,

so we can also do this by #xx 100%#

#3/40 xx 100%#

=#7.5%#

Three numbers add up to 210. The second number is 10 more than the first and the third number is 3 times the first. Find the numbers by modelling the problem using an algebraic equation.

Answers

Answer:

I. First number, a = 40.

II. Second number, b = 50.

III. Third number, c = 120.

Step-by-step explanation:

Let the three numbers be a, b and c respectively.

Given the following data;

Translating the word problem into an algebraic equation, we have;

a + b + c = 210

b = a + 10

c = 3a

Substituting the value of b and c into the equation, we have;

a + a + 10 + 3a = 210

5a + 10 = 210

5a = 210 - 10

5a = 200

a = 200/5

a = 40

To find the value of b;

b = a + 10

b = 40 + 10

b = 50

To find c

c = 3a

c = 3*40

c = 120

How come this person didn’t divide EVERYTHING on the left by 2? I thought you had to...

Answers

The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.

In the expression

2 (6x - 1) + 2 (2x + 5)

both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:

(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)

… = 1 (6x - 1) + 1 (2x - 5)

… = (6x - 1) + (2x - 5)

and so on.

Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,

2×41 + 2×19 = 120

If you divide *everything* on the left by 2, you end up with fractions:

(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2

but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.

What is 8.478 in expanded form?

Answers

Answer: 1


explanation: the 1000 expands form

The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

What is an expanded form of numbers?

We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.

Given that, we are asked to find the expanded form of 8.478,

The expanded form is :-

8 =  1 place = 8×1

0.4 = 1/10 place = 4×1/10

0.07 = 1/100 place = 7×1/100

0.008 = 1/1000 place = 8×1/1000

Therefore,

8.478 = 8×1+4×1/10×7×1/100+8×1/1000

Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)
