Step-by-step explanation:

the simplest form 8/18 is 4/9

Answer:

b

Step-by-step explanation:

b is undefined bc remember that slope is rise/run

if the "run" is 0, then that makes it rise/0  and dividing by 0 is undefined

a has a positive slope bc it goes up from left to right

c has a negative slope bc it goes down left to right

d has a slope of zero -- and it makes sense bc the rise=0 and dividing zero by a nonzero number will equal zero

Answer:

10x+15y

Step-by-step explanation:

The equation in the standard form to represent this situation is 10x + 15y = 340.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that consider x to be the number of gift cards for ​$​10, and y to be the number of gift cards for ​$15.

Also it can purchase gift cards for $10 or ​$15 and have spent ​$340 on gift cards.

Therefore, equation would be;

10x + 15y = 340.

Hence, the equation in the standard form to represent this situation is 10x + 15y = 340.

ANSWER

14.3

EXPLANATION

angle = 21⁰

opposite side = 5.5

adjacent side = x

Knowing this, we must use tangent (opposite / adjacent)

tan (21⁰) = 5.5 / x

x = 5.5 / tan (21⁰) (use calculator)

x= 14.3

Answer:

The solution of (2,5) indeed equals the solution of the equation y=2x+1

Step-by-step explanation:

to solve just plug in the values.

y=2(2)+1 which gives us the y value of y=5

to solve for x, plug in y. 5=2x+1.

subtract 1 from both sides, and you get 4=2x

then divide 2 on both sides to get x, which is 2. therefore this is true.

Answer:

[x - 5]² + [y + 7]² = 6²

Step-by-step explanation:

It should be noted:

"h" represents the x coordinate of the center point, "k" represents the y coordinate of the center point, and "r" represents the radius of the circle.

When the values are substituted:

[x - 5]² + [y - (-7)]² = 6²

⇒ [x - 5]² + [y + 7]² = 6² = 36

Answer: The answer would be 16.

Step-by-step explanation:

[tex]a^{2} +b^{2} =c^{2} \\11^2+12^2=c^2\\121+144=c^{2} \\\sqrt{265} =\sqrt{c^2} \\c=16.27\\c=16[/tex]

16 is the smallest possible whole number for the length of the third side. By using the Pythagorean Theorem, we are able to find the third side.

Answer:

Pretty sure the answer is 3 pounds you can pretty much repeatedly take away 8.17 from 80 till you get 55.49

80 - 8.17 = 71.83

71.83 - 8.17 = 63.66

63.66 - 8.17 = 55.49

so 3 Pounds since you took 8.17 three times to get 55.49
