The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month. The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month. Write a system of equations to model th situation. If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month? How many each disc is sold in that month?

Answer: disagree its backwards

Step-by-step explanation: the x intercept always comes first so its actually (-4,2)

Answer:

Step-by-step explanation:

Now if you look at this wrong, the student would be correct. The student made a common mistake that many make. The mistake they made was they put the X and Y backwards when making the point. All they have to do is make sure they put the X first then the Y. What they should have put is (-4,2). For any other point, you would replace X and Y in the points. (X,Y)

Answer:

22

Step-by-step explanation:

180°-90°-68°=22

Answer:

A and B, but I’m gonna explain it the best I can too.

Step-by-step explanation:

5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.

Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.

This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression

they have to add up completely the same.

Answer:

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. A common symbol for a percentage is this symbol "%." Some abbreviations for it can be, "pct," or "pc."

Remember though that a percentage had no unit of measurement as it is a dimensions number.

Use the law of cosines:

Answer:

57

Step-by-step explanation:

cos F = (e² + g² - f²)/2eg

cos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)

        = 0.5516

∠F = arccos 0.5516

∠F = 57° (rounded to the nearest degree)

Step-by-step explanation:

A zucchini plant in Darnell’s garden was 13 centimeters tall when it was first planted. Since then, it has grown approximately 0.6 centimeter per day. a. Write a rule to describe the function. b. After how many days will the zucchini plant be 0.208 meter tall?

Answer: h(d) = 0.6d + 13; 13 days

Answer:

x = 7, y = 2

Step-by-step explanation:

x= 4y -1

since x is by itself 4y-1 will substitute for x in the other equation x+2y=11

it will become 4y-1+2y=11

+1 +1

add one to both sides since is doesn't have a variable.

it will become 4y+2y= 12 now add 4y+2y

becomes 6y=12

_ _

6 6

divide by 6 on each side and you get y=2.

now x=4(2)-1 you will substitute y into the first equation.

x=8-1 subtract 8 from 1 to get 7.

x=7

y=2

Answer:

slope= -3

y-intercept= 6

Step-by-step explanation:

1. Approach

To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.

2.Solve for the slope

The formula to find the slope of a line is;

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where (m) is the variable used to represent the slope.

Use the first two given points, and solve;

(1, 3), (2, 0)

Substitute in,

[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]

Simplify;

[tex]\frac{-3}{1}\\\\=-3[/tex]

3. Put equation into slope-intercept form

The equation of a line in slope-intercept form is;

[tex]y = mx + b[/tex]

Where (m) is the slope, and (b) is the y-intercept.

Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).

[tex]y=-3x+b[/tex]

Substitute in point (3, -3)

[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

Answer:

m=-3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

Slope = Rise/Run

We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.

Then we can do rise/run and 12/4

Which would divide into 3.

ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.
