Answer:

Correct: Option a. negative reciprocals

Step-by-step explanation:

Perpendicular lines are defined as those who intersect at an angle of 90°.

There is an easy way to find out if two equations of lines correspond to perpendicular lines or not.

If line 1 is

y=m1x+b1

And line 2 is:

y=m2x+b2

The condition for the lines to be perpendicular is that:

m1*m2=-1

Solving for m2:

[tex]\displaystyle m2 = -\frac{1}{m1}[/tex]

As seen, both slopes are negative reciprocals.

Correct: Option a. negative reciprocals

the middle value is the median

Answer:

1) b. 1.562x10⁸

2) a. 4.8x10⁶

4) d. 2.3x10³

5) a. 4.21x10 -⁶

6) 6.6835x10⁵

Step-by-step explanation:

1) (2.2x10⁴)•(7.1x10³)= 156200000

2) 9.6x10⁹÷2x10³= 4800000

4) 6.9x10⁸= 2300

5) 5.6x10 -⁷ + 3.65x10 -⁶= 4.21x10 -⁶

6) 6.72x10⁵ - 3.65x10³= 668350

Answer:

c.  (-4, 4)

Step-by-step explanation:

y = 0.8x + 7.2

20x + 32y = 48

20x + 32y = 48

20x + 32(0.8x + 7.2) = 48

20x + 25.6x + 230.4 = 48

45.6x + 230.4 = 48

45.6x = -182.4

x = -4

y = 0.8x + 7.2

y = 0.8(-4) + 7.2

y = -3.2 + 7.2

y = 4

Answer:

B. y=1/3x+4

Step-by-step explanation:

The graph shows a line with a slope of -3. Perpendicular slopes is the reciprocal with a different sign (positive or negative). The perpendicular of -3 is 1/3, and B. is the only option with this slope.

Answer:

B. y=1/3x+4

Answer:

Look at step-by-step explanation.

Step-by-step explanation:

First write everything in terms of sin and cos:

(sinx)(sinx/cosx) + (sinx)/(sinx/cosx) = (1/cosx)

Then simplify the expression where you can:

(sin^2)/(cosx) + (cosx) = (1/cosx)

Next find a common denominator and add the two numbers on the left side of the equation:

(sin^2)/(cosx) + (cos^2x)/(cos^2x) = (1/cosx)

((sin2^x)+(cos2^x)/(cosx)) = (1/cos)

Finally, use the identity, sin2^x + cos2^x = 1, to simply to numerator:

(1/cosx) = (1/cosx)

Answer:

84.3

Step-by-step explanation:

843 ÷ 10

The place value of 843 is

8 = Hundreds

4 = Tens

3 = Units or ones

Hence,

843 ÷ 10

= 843/10

= 84.3

Answer:

y = 11t + 8

Step-by-step explanation:

Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:

y = 11t + 8

Where "t" represents the amount of tickets bought.

Answer:

1+18-11+16

Step-by-step explanation:

if the elevator went up it will be plus but if the elevator came down it will be minus and then you will get 1+18 because it went up and then it go down 11 floor and it will be 1+18-11 and then it went up again 16 floor so the last answer will be 1+18-11+16

Step-by-step explanation:

Answer:

Maximum of 50 persons

Step-by-step explanation:

Straight line equation

let the total prices be y

and the number of persons be x

1.  Brenda's Bridal Catering charges

the expression for the charges is

y=mx+c

y=18x+300---------------1

2.  Sarah's Complete Catering charges

the expression for the charges is

y=mx+c

y=15x+450---------------2

equating 1 and 2 we can then solve for the number of guest as

18x+300=15x+450

18x-15x=450-300

3x=150

divide both sides by 3

x=150/3

x=50

x<=50

Therefore she can invite a maximum of 50 persons
