What is (9,4) reflected over the x-axis

Answer:

y=mx+b

Step-by-step explanation:

Answer:

y=mx+b

Explanation:

The slope-intercept formula is y=mx+b. The b represents the y-intercept, which is the point where a line on a graph meets the y-axis. The coordinates for this would be (0,b). The m represents the slope, which is the rate of change. The x represents any x variable that you plug in. The y represents the y variable.

what the hell is this question

Answer:

40

Step-by-step explanation:

divide 320 by 8 and get 40 cause ratio is 1:8 so answer is 40:320

Answer:

All it says is PDF NOT AVAILABLE.. can you type the question out.

Answer:

x=20

Step-by-step explanation:

7+0.20x=5+0.30x              

then take the 7 and subtracet the 2 from it, then take the 0.30 and subtract the 0.20 from it then you should get 2=0.10x      

then to get rid of the 0.10 you take it and divide it from the 2 which gives you 20 then you have 20=x and thats your answer

The exact value of cos (α + β) is (4√2-21) / 15.

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Given that,

Sin α = 2/5, and α is in second quadrant,

cos β = 1/3 , and β is in fourth quadrant

Since, α is in second quadrant, the value of cos α will be negative.

The value of cos α, by right angle triangle property,

cos α = -√21 / 5  

Since, β is in the fourth quadrant, the value of  sin β will be negative.

The value of sin β  = -  2√2 / 3

Cos (α + β) = cos α.cos β - sin α. sin β

Substitute the values here,

Cos (α + β) = (-√21 / 5)  . 1/3 - 2/5. ( -  2√2 / 3)

                   = -21/15 + 4√2/15

                   =  (4√2-21) / 15

The value of cos (α + β) is (4√2-21) / 15.

Step-by-step explanation:

Answer:

X=62

Step-by-step explanation:

X=62 because the side where x is and where the other degree is, they are congruent. And since you have to add 12 it would have to be 62 to be equal to 74.

Answer:

I will answer in English, you can translate it after, as this is math, will be easier to read.

This can be translated to:

Present the fraction:

a) - 7/9 as a fraction with 27 denominator

b) 7/17 as a fraction with 102 denominator

c) 13/16 as a fraction with 80 denominator

d) 11/13 as a fraction with 78 denominator

a) We can multiply both numerator and denominator by the same number, and the quotient remains the same:

We know that 9*3 = 27

then: (-7/9)*(3/3) = -21/27

b) Here we can use that 102 = 17*6

Then we multiply the numerator and denominator by 6:

(7/17)*(6/6) = 42/102.

c) We can use that 16*5 = 80.

Then we should multiply both denominator and numerator by 5.

(13/16)*(5/5) = 65/80

d) We can use that 6*13 = 78, then we can multiply both denominator and numerator by 6.

(11/13)*(6/6) = 66/78

Answer:

Step-by-step explanation:

2x+6=3(x+2)-x  

2x+6=3x+6-x  add x to both sides

3x+6=3x+6  subtract 3x

6=6

X can equal any real number to make this a true equation

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.

A = 16/4 marked blocks = 25%

B = 16/8 marked blocks = 50%

C = 16/6 marked blocks = ?

D = 16/10 marked blocks = 62,5%

So answer would be A

Use the rise/run strategy to draw the line. Start at the y-intercept (0, 12), and count 8 up and 1 to the right to the point (1, 20). Then, draw a line through the points. Test the point (3,36) in the equation y = 8x + 12 to verify that the line is correct.
