Answer:

[tex]\displaystyle m=\frac{5}{4}[/tex]

Step-by-step explanation:

The slope between any two points is given by the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let’s let (4, 5) be (x₁, y₁) and let (8, 10) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{10-5}{8-4}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{5}{4}[/tex]

Therefore, the slope between the two points is 5/4 or 1.25.  

Answer:

50 minutes (I think)

Step-by-step explanation:

A= 800 - 6m

B = 1000 - 10m

800 - 6m = 1000 - 10m

4m = 200

50 = m

Answer:

TRUE

Step-by-step explanation:

y-4 = 2(x-1)

here, 4 is representing the y value and 1 is representing the x value.

And the slope is 2.

Answer:

$4 per Turkey

Step-by-step explanation:

Look on the graph and follow every number to the cost:

2 Turkeys: $8

4 Turkeys: $16

5 Turkeys: $20

Notice how there is a Pattern:

8, 16, and 20 are all multiples of 4  

4 x 2 = 8

4 x 4 = 16

4 x 5 = 20

So, the constant of proportionality for the coast per sandwich and Delicious Deli is $4

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

Explanation:

The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.

A solid boundary line means that points on the boundary are part of the solution set.

Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.

[tex]-5x + 4y \ge -1 \\\\-5(4) + 4(0) \ge -1 \\\\-20 \ge -1 \\\\[/tex]

This is false because -20 is not larger than -1. It's the other way around.

This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.

The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.

Q is located to theight of the x-axis, meaning the first number is a positive, and going up a little past 2 but not past 3. and in the middle so 2 1/2.

Answer:

1.7 degrees fahrenheit

Step-by-step explanation:

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

Work Shown:

y = 4x - 20

4x - 20 = y ...... swap both sides

4x = y + 20 ..... adding 20 to both sides

4x - y = 20 .... subtracting y from both sides

The equation is now in standard form (Ax+By = C) where,

Step-by-step explanation:

first =2* second

second=2*third since the third is half of second

first =2*2*third=4*third

now lets put them all together

first+second+third=224

4*third+2*third+third=224

7*third=224 so the third part is 32

but we need the second piece

2*32=64

Step-by-step explanation:

I have done the test bere

The ratio 2 to 5  can be written as 2 : 5 or 2/5 or 2/(2 + 5) = 2/7 and

5/(2 + 5) = 5/7.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

A ratio a : b can be written as a/b. It can also be written as a/(a + b) and

b/(a + b).

So, the ratio 2 to 5  can be written as 2 : 5 or 2/5 or 2/(2 + 5) = 2/7 and

5/(2 + 5) = 5/7.

Step-by-step explanation:

Answer:

B

Graphs aren't mandatory, but they may help visual learners see why an equation works a certain way. Also, they are a visual tool to quickly find a solution to a problem. Furthermore, they help with presentations to quickly convey an idea to someone (who may not be well versed in mathematics).

For example, if you save $10 a week and already have $50 in a savings account, then the equation you graph is y = 10x+50. Here x is the number of weeks and y is the amount saved.

Now let's say you want to find out how many weeks it would take to have $90 total. You could use guess and check to get the answer. Or you could use algebra and the substitution property. The visual way would be to graph y = 10x+50 and y = 90 together to note how the two lines intersect at (4, 90) to indicate it will take x = 4 weeks to have y = 90 total.

Step-by-step explanation:

Given that:

Jillian is willing to trade her wool cards for David ore cards

The double number line indicates that:

David will trade three ore cards to Jillian for six wool cards;

Based on the ratio, we have:

[tex]= \dfrac{6}{3}[/tex]

= 2

Thus, the number of wool Jillian would need to trade for 1 ore card will be

= 1 × 2

= 2

For 2 ore card

= 2 × 2

= 4

For 3 ore card

= 3  × 2

= 6

The number of wool Jillian would need to trade for 4 ore card will be

= 4 × 2

= 8
