Answer:

1) 3x - 15y = 5

2) 6x - 21y = 7

Step-by-step explanation:

standard form:  Ax + By = C

1) y = 1/5x + 1/3

multiply each side by 15 to eliminate fractions: 15y = 3x + 5

final form: 3x - 15y = -5

2) y = 2/7x - 1/3

multiply each side by 21 to eliminate fractions: 21y = 6x - 7

final form: 6x - 21y = 7

Answer:

d

Step-by-step explanation:

Answer:

D. y = -3x

Step-by-step explanation:

plug x into the equation:

y = -3(-4) = 12 (s0 when x = -4, y = 12)

y = -3(-3) = 9

y = -3(-2) = 6

y = -3(-1) = 3

Answer:

1 hour/ 34 minutes

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Unit prices come from dividing the price, $6.99, by the amount of product, 6,

6.99 ÷ 6 = 1.165

Now, because you cannot have more than two digits in the cents part, you would round that up to $1.17 which is over $1.05 dollars per bottle.

Answer: 844.131607

Step-by-step explanation:

750/100=7.5

7.5 is 1%

22.5 is 3%

YEAR 1 (750+22.5) 772.5

772.5/100

7.725 is 1%

23.175 is 3%

YEAR 2 (23.175+772.5) 795.675

795.675/100

7.95675 is 1%

23.87025 is 3%

YEAR 3 (23.87025+795.675) 819.54525

819.54525/100

8.1954525 is 1%

Answer:

88.16

Step-by-step explanation:

You will have to use tan to solve it

The value of x round to the nearest tenth is,

⇒ x = 85

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Base of height = 500

Angle = 10°

Now, We can formulate;

⇒ tan 10° = x / 500

⇒ 0.17 = x / 500

⇒ x = 85

Thus, The value of x round to the nearest tenth is,

⇒ x = 85

Answer:

6

Step-by-step explanation:

20 times 0.3 is 6

Answer:

reduced by 20% so that means it is going to be 20% cheaper. You need to take off 20% of $60

20% is 0.2

of in math ALWAYS means multiply

0.2 X 60 = 12

You get 12 off  

60 - 12 = 48

the new price is $48.00

Here is another way. You get 20 % off and that leaves 80% that you have to pay.

80% of 60  

= 0.8 x 60

= 48

You pay $48.00

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

If you subsitute for x, x will only repeat if it has the same y value.

Yes, The given relation is a function.

Here,

The relation is given as; Y = 3x

We have to find the given relation is a function or not.

What is Function?

A relation is said to be function if there is exactly one value for each value of y.

Now,

The given relation is,

Y = 3x

When, we put x = 1 then y = 3

And, when x = 2 then y = 6 and so on.

Clearly, there is exactly one value of x for value of y.

So, The given relation is a function.

Answer:

The correct answer is

[tex]1296 { x}^{2} [/tex]

Answer:

[tex]x=2,\\x=-2,\\x=\sqrt{3},\\x=-\sqrt{3}[/tex]

Step-by-step explanation:

This is a quadratic in disguise. Let [tex]n=x^2[/tex]. We can rewrite the problem as a quadratic to solve:

[tex]n^2-7n+12=0,\\(n-3)(n-4)=0,\\n=3,\: n=4[/tex].

Now plug in these values of [tex]n[/tex] to solve:

[tex]\begin{cases}x^2=4, \:x=\pm 2\\\\x^2=3, x=\pm\sqrt{3}\end{cases}[/tex].

Therefore, our solutions are [tex]x=\pm 2, \:x=\pm\sqrt{3}[/tex].

Answer:

x = 2√3

Step-by-step explanation:

The sides of a 30-60-90 triangle are always in the ratio 1:√3:2.

The length of the side opposite the 90° angle is 4, so the length of the side opposite the 30° angle is 2 and the length of the side opposite the 60° angle is 2√3.

x = 2√3

Answer:

There is no solution for either variable without further information, as there are two variables given, but only one relationship between them.

You could however use them as a description of a line, which gives every possible solution.

35x - 7y = 49

7y = 35x - 49

y = 5x - 7

We now have an expression describing a line with a slope of five, which crosses the y axis at (0, -7) and the x axis at (1.4, 0)
