Answer: y is a false statement

Step-by-step explanation: put all the y terms on one side and all the constants on the other. i'm going to move all the y terms to the right and the constants to the left. on the left we have a -5 leftover and on the right it would be 7y-y-6y. if you add those terms together, you're left with -5=0 which is not possible. y is a false statement

Answer:

The answer is A

Step-by-step explanation:

Answer:

m < 2 = 45°

Step-by-step explanation:

m < 1 and m < 3 are corresponding angles that lie on the same side of the transversal.  Since they are corresponding angles, then it means that they have the same measure.

Therefore, if m < 1 = 135°, then m < 3 = 135°.

Also, the sum of m < 2 and m < 3 = 180° because they are supplementary angles.

Therefore:

m < 2 + m < 3 = 180°

m < 2 + m < 135° = 180°

m < 2 = 180° - m < 135°

m < 2 = 45°

Answer: Im gonna take you down like a sweet muffin.

The number of escapes, takedowns and nearfalls Anahi have is 6, 24 and 70 respectively.

escape is worth 1 point,

a takedown is worth 2 points, and

a nearfall is worth 3 points.

escape = x

takedown = y

nearfall = z

x + y + z = 100. (1)

x + 2y + 3z = 240. (2)

y = 4x. (3)

substitute (3) into both equation

x + 4x + z = 100

x + 8x + 3z = 240

5x + z = 100. (4)

9x + 3z = 240. (5)

Multiply (4) by 3

15x + 3z = 300 (6)

9x + 3z = 240. (5)

Subtract (5) from (6) to eliminate z

6x = 60

x = 60/6

x = 6

Substitute into (3)

y = 4x

y = 4(6)

y = 24

Therefore, from (1)

x + y + z = 100.

6 + 24 + z = 100

30 + z = 100

z = 100 - 30

z = 70

Answer:

a) linear, straight when graphed and no exponents

b) quadratic, x has exponent

c) quadratic, x has exponent

d) linear, no exponent

e) quadratic, x has exponent

f) i think it's neither because there's two variables that can't add together

Step-by-step explanation:

Answer:

A is linear because a linear equation is mapped in the form y=ax+b and results in a straight line when graphed. This equation has a slope, 1, which occupies the space for a and a y-intercept of 3 which occupies the space for b

B is neither because it doesn't fit the linear form or the quadratic form (which is constrained by the equation y=ax^2+bx+c. The highest degree for this form is 2.) I believe this function is actually a type of cubic which is not an option for the question.

C is a quadratic because it follows the form y=ax^2+bx+c and results in a parabola

d. 3x-y=5 is linear because even though it is not in the y=ax+b form, it can be manipulated into it by subtracting 3x from both sides and then dividing by -1 on both sides to get y=3x-5 which fits the form and graphs a line.

e. 5-x^2=89 would be neither because there is only one variable and there is no value of y that can be solved for. While we can find an x value (or perhaps multiple x values depending on the equation) it wouldn't result in a graphable equation which is a necessity to be classified as a linear or quadratic. In fact, I believe this is actually just an equation and not a function at all and since linear and quadratics are forms of functions they cannot be either. This is because a function is defined as a relation between two variables where each input has one (and only one) output and this equation doesn't have two variables and wouldn't have an output.

f. Neither for the same reason as in e

the Answer is...:

X=195

Answer: X is 15

Step-by-step explanation:

Multiply both sides with 3

(x/3) + (10 x 3) = 15 x 3

x + 30 = 45

Add - 30 to both sides

x + 30 - 30 = 45 - 30

x = 15

According to the word problem question;

If the salesperson earns 9 percent commission on sales;

In essence, 9/100 of the sales proceedings belongs to the salesperson.

Mathematically; the equation for the amount he or she earns in commission is;

Consequently, if the amount sold is $6,000;

The amount he or she earns in commission is;

c = $540.

The answer in ordered pair form is therefore;

Answer:

y = 13x - 55

Step-by-step explanation:

So this is what we know

Selling price = $13 per copy

Expenses = $55

The formula for profit in this case is:

Profit = total selling price - expenses

In which y is the profit

The total selling price is 13x. x here is for the number of manuals she sells

The expenses are $55.

This then becomes y =13x - 55

22, 24, 26

Step-by-step explanation:

2n - 2 + 2n + 2n + 2 = 72

6n = 72

n = 72/6

n = 12

∴ so three consecutive even integers whose sum is 72 :

2n - 2

= 2(12) - 2

= 24 - 2

= 22

2n

= 2(12)

= 24

2n + 2

= 2(12) + 2

= 24 + 2

= 26

verification

22 + 24 + 26

= 46 + 26

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

The two requirements for a proportional relationship are: The ratio of the two variables maintain the same ratio.

56 x 56 = 3136

If you subtract 500 from 3136 you get 2636.

Using this information you know subtracting 2636 from 3136 gives you 500.
