Answer:
2 and - 1
Step-by-step explanation:
Calculate the gradients using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, -3) and (x₂, y₂ ) = (3, 7) ← 2 points on line A
[tex]m_{A}[/tex] = [tex]\frac{7+3}{3+2}[/tex] = [tex]\frac{10}{5}[/tex] = 2
with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (7, - 2) ← 2 points on line B
[tex]m_{B}[/tex] = [tex]\frac{-2-7}{7+2}[/tex] = [tex]\frac{-9}{9}[/tex] = - 1

Answers
Answer:
No it would not be because two sides added up would not equal the other side
Step-by-step explanation:
Answer:
No it is not.
Step-by-step explanation:
All right triangles follow the Pythagorean theorem [tex]a^2+b^2=c^2[/tex] where the squares of the two shorter sides of the right angle triangle is equivalent to the square of the longest side.
Squares of the two shorter sides:
[tex]9^{2}+15^{2}=306[/tex]
Square of the longer side:
[tex]17^{2}=289[/tex]
∵ [tex]306\neq 289[/tex], ∴ the triangle is not a right angle triangle.

Find the values of x and y.
X= __
Y= __
Answers
Answer:
x = 20
y = 100
Step-by-step explanation:
To figure out x do this.
3x + 2x = 7x - 40 (collect like terms)
5x = 7x -40 (subtract 7x on both sides)
-2x = -40 (divide by -2 on both sides)
x = 20
Plug in to get y
Since 7x - 40 and y are vertical they equal the same amount
7(20) - 40 = y (multiply 7 by 20)
140 - 40 = y (collect like terms)
100 = y

Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize. Suppose that Isaac is going to buy 6 boxes of this cereal, and let X represent the number of prizes he wins in these boxes. Assume that these boxes represent a random sample, and assume that prizes are independent between boxes. What is the probability that he wins exactly 2 prizes in the 6 boxes?
Answers
Answer: 0.3 on khan academy
Step-by-step explanation: ♂️
The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.
Calculation of the probability:Since Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize this mean
So,
P(box containing prize) = 1/4 = p =0.25
So,
q=1 - p
= 0.75
And total box (n)=6
Let us assume x be number of prize win.
So,
Probability that he will win exactly two prize is
P(X=2)= [tex]\binom {6}{2}(0.25)^2(0.75)^4[/tex]
= 0.2966
=0.30(approx)
hence, The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.

If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answers
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
