Answer:
x = sqrt(95)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
7^2 + x^2 = 12^2
49 + x^2 =144
Subtract 49 from each side
x^2 = 144-49
x^2 = 95
Take the square root of each side
sqrt(x^2) = sqrt(95)
x = sqrt(95)
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
7^2 + x^2 = 12^2
49 + x^2 =144
Subtract 49 from each side
x^2 = 144-49
x^2 = 95
Take the square root of each side
sqrt(x^2) = sqrt(95)
x = sqrt(95)

and a pack of LARGE cups costs $2.40. She
paid a total of $21.60. How many packs of

Answers
Step-by-step explanation:
1.80x + 2.40y = 21.60

The straight line 3x + 4y = 24 cuts the y - axis at the point A and cuts the x - axis at the point B. What is the distance AB?
Answers
Step-by-step explanation:
the answer is in the above image
The distance between point A and point B is 10 units.
What is the distance between two points on a plane?The distance between two points on a coordinate plane (x, y) and (x, y) is
= √[(x₂ - x₁)² + (y₂ - y₁)²] units
The given straight line is 3x + 4y = 24.
This straight line will cut the x-axis at a point where y = 0.
Therefore, 3x + 4(0) = 24
⇒ 3x = 24
⇒ x = 8
Therefore, the coordinates of the point A is (8, 0).
Similarly, this straight line will cut the y-axis at a point where x = 0.
Therefore, 3(0) + 4y = 24
⇒ 4y = 24
⇒ y = 6
Therefore, the coordinates of the point B is (0, 6).
Therefore, the distance between point A and point B is
= √[(0 - 8)² + (6 - 0)²] units
= √(64 + 36) units
= √100 units
= 10 units (negative sign is avoided.)

PLEASE HELP! SEE PHOTO FOR QUESTION
Answers
Answer:
A
Step-by-step explanation:
Intercepts are basically points where if one of the coordinates is a number above 0, the other one HAS TO BE 0
Since there are three points where there are x-intercepts (since the y is 0), there will be three x-intercepts.
Since there is only one point where there are y-intercepts (since the x is 0), there will be only one y-intercept.
The intercepts don't give an exact answer so you would have to estimate where they are on the graph. For example, the y-intercept is between 20-30 and is leaning more towards 30, so you would think it's around 27-29 (And if you look at option A, you can see that it's (0,28))
You got the answer wrong because for one of the x-intercepts, you said that it was negative when it was actually positive. (I believe it was the (2.3,0) one.)

Comparing this equation with vertex form of a parabola , where (h,k) is the vertex
h = 2
