The equations of four lines are given. Identify which lines are perpendicular.


Line 1: y+8x=−5


Line 2: x+16y=−5


Line 3: y=−6x−7


Line 4: y+3=18(x−1)


Lines 2 and 3 are perpendicular.

Lines 1 and 2 are perpendicular.

All four lines are perpendicular.

Lines 1 and 4 are perpendicular.

Answers

Answer 1

Answer:

None of the options match

Step-by-step explanation:

First let's check option 1: lines 2 and 3.

line 2 in mx+b form: y=-1/16x -5

line 3, already in mx+b form: y=-6x-7

if it was perpendicular, the slopes should have been -1/16 and 16 or -6 and 1/6.

now for the 2nd option: lines 1 and 2.

line 1 in mx+b form: y=-8x-5

line 2 in mx+b form: y=-1/16x-5

Again, the slopes do not match, they should have been -8 and 1/8 or -1/16 and 16.

For the 3rd option: all lines

this is obviously wrong since lines 1, 2 and 2, 3 are not perpendicular themselves. No need to bother checking this option.

Lastly, 1 and 4.

line 1 in mx+b form: y=-8x-5

line 4 --> y+3=18x-18 --> y=18x-21

This is also wrong since the slopes should have been -8 and 1/8 or 18 and -1/18.

To conclude, I think the answer is none. None of the combinations on here are perpendicular anyways...

Answer 2

Answer:

D

Step-by-step explanation:

We have the four lines:

[tex]\displaystyle\text{Line 1: }y+8x&=-5 \\\\ \text{Line 2: } x+\frac{1}{6}y&=-5\\\\\text{Line 3: } y&=-6x-7 \\\\\text{Line 4: } y+3&=\frac{1}{8}(x-1)[/tex]

Remember that for two lines to be perpendicular, their slopes are negative reciprocals of each other.

So, let’s determine the slope of each line.

For Line 1, we can rewrite our equation as:

[tex]y=-8x-5[/tex]

So, the slope of Line 1 is -8.

We can rewrite Line 2 as:

[tex]\displaystyle \begin{aligned} \frac{1}{6}y&=-x-5\\y&=-6x-30\end{aligned}[/tex]

So, the slope of Line 2 is -6.

The slope of Line 3 is also -6.

And the slope of Line 4 is 1/8.

So, the slopes of perpendicular lines must be negative reciprocals.

The negative reciprocal of -8 (slope of Line 1) is 1/8. We multiply by a negative and then take the reciprocal.

Since the slope of Line 4 is 1/8, this means that Lines 1 and 4 are perpendicular.

For Lines 2 and 3, they have the same slope, not negative reciprocals of each other.

So, they will instead of parallel instead of perpendicular.

And Line 1 is perpendicular only to Line 4, and no other line.

Therefore, our answer is D.

Describe the transformation of the graph y = (x)^3 + 6

Answers

The graph of y = x^3 + 6 is the result of shifting y = x^3 up 6 units

If f(x) = x^3, then g(x) = f(x) + 6 leads to g(x) = x^3+6.

The reason we shift up 6 is because we're adding 6 to the y coordinate.

Think of y = f(x), so f(x)+6 is the same as y+6.

The number 8 % as a fraction in the simplest from is 2/25

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the value of A is = 8 %

So , the equation will be

The value of A = 8 %

Now , the value 8 percentage can be written as a fraction of 100

So , the value of A will be

The value of A = 8/100

Now , on dividing the numerator and denominator by 4 , we get

The value of A = 2 / 25

So , the value of A in the simplest form of the number A is 2/25

Hence , The number 8 % as a fraction in the simplest from is 2/25

Joshua and Brandon buying a pizza for their math class. They will spend $77. Joshua will pay six times more then Brandon. How much will Joshua pay?

Answers

Answer:

$66

Step-by-step explanation:

For this problem, we will simply write two equations to solve how much each person will pay.

Let x represent the amount of dollars joshua pays and y represent the amount of dollars brandon pays.  Then we can say the following:

x + y = 77

x = 6y

Using these two equations, we can solve for how much Joshua will pay.

x + y = 77

6y + y = 77

7y = 77

y = 11

x + y = 77

x + 11 = 77

x = 77 - 11

x = 66

Hence, Joshua pays $66 and Brandon pays $11.

Cheers.

Step-by-step explanation:

The parenthesis basically mean "multiply". So, this is a simple equation meaning -7 x 2. And remember, anytime we multiply a positive by a negative, you get a negative. So, simply multiply 7 x 2 = 14 and add a negative sign to make the solution true. So, -7 x 2 or (-7)2 = -14

Marshall gave the cashier $100 to pay for 4 new video games. The cashier gave him $4.08 in change. Each video game cost the same amount. What is the cost in dollars and cents for each video game? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.

Answers

Answer:

Cost in dollars and cents for each video game = $23.98

Step-by-step explanation:

Total amount Marshall paid for four video games = $100

Total change given to Marshall = $4.08

Actual cost of the video games = Total amount Marshall paid for four video games - Total change given to Marshall

= $100 - $4.08

= $95.92

Total number of videos games bought = 4

What is the cost in dollars and cents for each video game

Cost of each video game = Actual cost of the video games / Total number of videos games bought

= $95.92 / 4

= $23.98

Cost in dollars and cents for each video game = $23.98

23 dollars .98 cent

Write the expression (2−3i)+5i(1−3i)
as a complex number in standard form.

Answers

Answer:

17 + 2i

Step-by-step explanation:

Given

(2 - 3i) + 5i(1 - 3i) ← distribute both parenthesis

= 2 - 3i + 5i - 15i²  [ i² = - 1 ]

= 2 + 2i + 15

= 17 + 2i ← in standard form

The standard form of a complex number (2 − 3i) + 5i(1 − 3i) is 17 + 2i.

What is a complex number?

A complex number is a component of a number system that includes the imaginary unit, represented by the letter i as an extension of the real numbers.

Given:

(2−3i) + 5i(1−3i)

Use the distributive property and expand the expression,

(2 − 3i + 5i - 15i²)

2 + 2i - 15(-1)           [i² = - 1]

2i + 17

Therefore, the standard form of a complex number (2 − 3i) + 5i(1 − 3i) is 17 + 2i.
