Answer 1

Answer:

The answer is A

Step-by-step explanation:

Happy valentines

Answer 2

Answer:

Choice 2

Step-by-step explanation:

The downward sloping line has a y intercept of +1 and a slope of -2, hence its equation is y=-2x+1. Since the shaded region includes some points on the line and above the line, we know that the relation must be >=. Thus, one of the inequalities must be

y>=-2x+1

The upward sloping line has a y intercept of -2 and a slope of +1, hence its equation is y=x-2. Since the shaded region includes some points on the line and below the line, we know that the relation must be <=. Thus, the other inequality must be

y<=x-2

the directions are : The table shows a proportional relationship between x and y. What is the unit rate of y per x.

Answers

Answer:

Step-by-step explanation:

To find the unit rate you can pick any row and do y divided by x

For example, x = 3 and y = 12 so you can do 12 / 3 = 4.

You could also use x = 5 and y = 20, so it would be 20 / 5 = 5

If f(x) = -22 - 2x -1, then f(x+1) = -x? - 2x - 4?

Answers

Answer:

f(x+1) = -21 -2x-4

Step-by-step explanation:

Explanation:-

Given that the function f(x) = -22-2x-1

f(x+1) = -22 -2( x+1) -1

= -22 -2x-2-1

= -2x -21 -4

f(x+1) = -21 -2x-4

Height: 6.7 Length: 22

Step-by-step explanation:

Use Soh (sin(angle)=[tex]\frac{opposite}{hypotenuse}[/tex]) Cah (cos(angle)=[tex]\frac{adjacent}{hypotenuse}[/tex]) Toa (tan(angle)=[tex]\frac{opposite}{adjacent}[/tex])

Height:

You'd use sin so the equation is sin17=x/23 which is equal to (rounded) 6.7

Length:

You'd use cos so the equation is cos17=y/23 which is equal to (rounded) 22

*You always need to use a calculator when using sin, cos, and tan*

*SohCahToa is an easy way to remember the equations!*

In a bag, there are only black pins, green pins, pink pins and white pins
A pin is taken at random out of the bag
Complete the table

Answers

Answer:

P of white: 0.26

P of green: 0.39

Step-by-step explanation:

Assume the probability of a white pin is p.

Then the probability of a green pin is (3/2)p because their ratio is 3:2.

The sum of the probabilities must be 1.

0.1+(3/2)p+0.25+p=1

(5/2)p+0.35=1

(5/2)p=0.65

p=(2/5)(0.65)=0.26

(3/2)p=0.39

If 4x- 7 = 2x, then 2x = ?

Answers

If [tex]4x-7=2x[/tex], then [tex]2x=7[/tex].

Hope this helps.

Answer:

Step-by-step explanation:

We solve for x first.

So: 4x - 7 = 2x

Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x

2x - 7 = 0

Add 7 to both sides: 2x - 7 + 7 = 0 + 7

2x = 7

Divide by 2: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]

x = [tex]\frac{7}{2}[/tex]

Now, we substitute x for [tex]\frac{7}{2}[/tex] like this:

2 ( [tex]\frac{7}{2}[/tex]) = 7

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 40 kg if a mix that will sell for $1.30 per kg?

Answers

Answer:

40kg

Step-by-step explanation:

x + y = 60, y = 60 - x

x(2.50) + y(1) = 60(1.50)

Substitute:

2.50 x + 60 - x = 90

1.50x = 30

x = 20 kg

y = 40 kg

5L of a solvent cost $72 per liter than the value of 5L of solvent is?

Answers

Answer:

$360.

Step-by-step explanation:

Given that 5 liters of a solvent cost $ 72 per liter, to determine the value of 5 liters of solvent the following mathematical calculation must be carried out, consisting of multiplying the value per liter by the number of liters to be purchased:

72 x 5 = X

360 = X

Therefore, the 5 liters of solvent will have a cost of $ 360, that is, five times the value of the liter, which is $ 72.

try to graph y=0.4 x

Answers

Answer: y = 0.4x in desmos

Step-by-step explanation:

Answer:

Not applicable.

Step-by-step explanation:

You could use Desmos as another person answered. However, if you are graphing by hand, simply choose two points and draw a straight line between them.

For example, you could pick x = 0 and x = 1. This gives you the two points (0, 0) and (1, 0.4)

Plot those two points and use a straight edge to draw a line between the two.

In case you are having trouble plotting (1, 0.4) since it is a decimal, try setting x = 5, you will get (5, 2) which should be much easier to graph.
