Answer:

y = -x - 4

Step-by-step explanation:

Looking at this graph straight off the bat we see the line is going downwards from left to right which is an indication of a negative slope. The slope is 1 considering the line's rise/run (2 units/2 units down on the graph). Thus, we know our slope is 2/2 = 1. Thus, our slope would appear as -(1)x or -x in the equation.

Next, we need to identify where the line crosses the y-axis to identify our y-axis point. Tracing the line, we see that it comes into contact with the vertical y-axis at -4 (4 units South on the y-axis).

Putting these both together we see the equation of the line is y = -x - 4.

Answer:

x = 8

Step-by-step explanation:

Firstly, create an equation or formula

- because they are congurent, IN = AT, so:

2x+10 = 26 (minus 10 from both sides)

2x = 16 (divide both sides by 2)

x = 8

Sub into the formula:

2 x 8 + 10 = 26

26 = 26

Answer:

the awnser is c

Step-by-step explanation:

first you take 41.20$ and you subtract you're 5%

therefore that gives you 39.14$

subtract 39.14$ from 41.20

and you get a left over of 2.06$

therefore c is you're awnser

A percentage is a number or ratio expressed as a fraction of 100.

The amount spent on shipping and handling charges is $2.06.

A percentage is a number or ratio expressed as a fraction of 100.

Example:

50% = 50 / 100 = 1/2

20% = 20 / 100 = 1/5

25% = 25 / 100 = 1 / 4

10% = 10 / 100 = 1 / 10

We have,

Total spending on books = $41.20

Shipping and handling charges = 5% of $41.20

The amount spent on shipping and handling charges:

= 5% of $41.20

= 5/100 x 41.20

= 5/100 x 4120/100

= 5 x 4120 / 10000

= 20600 / 10000

= $2.06

Thus the amount spent on shipping and handling charge is $2.06.

Part A

We have 20 cards, 4 of which are kings (one of each suit). The probability of getting a king on the first draw is 4/20 = 1/5.

===========================================================

Part B

We have 20-4 = 16 cards that aren't a king out of 20 total.

The probability of getting a non-king card is 16/20 = 4/5

After selecting the first card and not putting it back, we have 20-1 = 19 cards left. Four of which are a king, so 4/19 represents the probability of getting a king on this draw.

So (4/5)*(4/19) = 16/95 is the probability of getting a king on the second draw where the first draw is not a king.

===========================================================

Part C

16/20 is the probability of getting no kings on the first draw

15/19 is the probability of getting no kings on the second draw (notice I stepped the values down by 1)

14/18 is the probability of getting no kings on the third draw

Multiplying out the fractions gives

(16/20)*(15/19)*(14/18) = 28/57

I skipped a few steps when multiplying the fractions but you get the idea.

The probability of drawing 3 cards, none of which are a king, is 28/57

Subtract this from 1 to get the complementary probability

1-(28/57) = 57/57 - 28/57 = (57-28)/57 = 29/57

This works because we have two choices: either we get no kings, or we get at least one king. So that's why the two events are complementary and their probabilities add to 1.

No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because

- 15:12 = 5:4

- 5:3

- 10:6 = 5:3

Given,

5:3 and 10:6 are equivalent ratios.

We need to see whether these ratios are equivalent to 15:12.

The ratios which are equal are called proportional ratios.

Example:

1:2 = 5:10 = 6:12 = 7:14

5/10 = 1/2

6/12 = 1/2

7/14 = 1/2

We have,

5:3 and 10:6

- 5/3

- 10/6 = 5/3

We have,

15:12

= 15/12

= 3x5/3x4

= 5/4

We see that 5:3 and 10:6 are not equivalent to 15:!2.

Thus,

No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because

- 15:12 = 5:4

- 5:3

- 10:6 = 5:3

Answer:

x=35

y=145

z=25

Step-by-step explanation:

(do first)x:

55 + 90 = 145

180-145=35

(do last)y:

25+10=35

180-35=145

(do second)z:

65+90=155

180-155=25

Answer:

x = 35, y = 145, z = 25

Step-by-step explanation:

All triangles' angles have a sum of 180°. Because we know this, we can solve the first triangle easily.

180 = x + 90 + 55

180 = x + 145

35 = x

Angles x and y are what we call suplementary angles. This means they have a sum of 180°.

180 = 35 + y

145 = y

Once again, we know that triangles have a sum of 180°. So the next triangle should now be easy to solve.

180 = 10 + 145 + z

180 = 155 + z

25 = z

Answer:

f(1) = - 5, f(5) = 6

Step-by-step explanation:

(a)

f(1) with x = 1 is in the interval x ≤ 1 , thus

f(1) = - 5

(b)

f(5) with x = 5 is in the interval x > 1 , thus f(x) = 2x - 4 , so

f(5) = 2(5) - 4 = 10 - 4 = 6

Answer:

third option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

y + 4 = 2(x - 3) ← distribute parenthesis

y + 4 = 2x - 6 ( subtract 4 from both sides )

y = 2x - 10 ← in slope- intercept form

The slope- intercept form of  the equation y+4=2(x−3) is y = 2x - 10 .

Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.

Given:

The equation is

 y+4=2(x−3)

We have to find the correct slope-intercept form of the equation.

The equation of a line in slope- intercept form is

y = mx + c

According to given question we have,

y + 4 = 2(x - 3)

Distribute parenthesis we get,

y + 4 = 2x - 6

subtract 4 from both sides  we get,

y = 2x - 10

Therefore , the  slope- intercept form of  the equation y+4=2(x−3) is y = 2x - 10 .

Answer:

[tex]YZ = 19cm[/tex]

Step-by-step explanation:

To figure out what line YZ equals, we must first find x. And to do this, let's set up an equation.

Firstly, we know that XY is 8cm, and XZ is 4x+3. So, we know that XY + YZ will equal XZ. Let's set that up:

[tex]8 + 2x+7=4x+3[/tex]

Combine like terms.

[tex]2x+15=4x+3[/tex]

Subtract 2x from both sides.

[tex]15=2x+3[/tex]

Subtract 3 from both sides.

[tex]12=2x[/tex]

Divide both sides by 2.

[tex]6=x[/tex]

Now, we just need to plug 6 into the equation of YZ.

[tex]2(6)+7[/tex]

[tex]12+7[/tex]

[tex]YZ = 19[/tex]
