Step-by-step explanation:
The slope of the above line = -2
slope of the line perpendicular to the above line = 1/2
If it passes through point (4,-3) , it's equation
A = 1, B = -2 and C = -10
A+B+C= 1+(-2)+(-10)
= 1-2-10
= 1-12
= -11
Answer:
A = 1, B = -2 and C = -10

Answer:
8, 5, 3 are the numbers.
Step-by-step explanation:
Let the three numbers are x, y , and z.
out of which x is the largest and z is the smallest number.
Sum of three numbers is 16.
x + y + z = 16------(1)
The largest number is equal to the sum of the other two.
x = y + z --------(2)
3 times the smallest number is 1 more than the largest.
3z = x + 1 ---------(3)
Now we put the value of x from equation (2) to equation (1)
x + x = 16
2x = 16
x = 8
By putting x = 8 in equation (3)
3z = 8 + 1
3z = 9
z = 3
Now we put the values of x and z in equation (2)
8 = y + 3
y = 8 - 3
y = 5
Therefore, the numbers are 8, 5, 3.

x = 8

4n^2+3=7n
make into trinomial
subtract 7n from both sides
4n^2-7n+3=0
if we can factor this, then we can asume that the factors are equal to zero becase if
xy=0 then assume x and/or y=0 so
to factor an equation in ax^2+bx+c where a is greater than 1 then
b=t+z
a times c=t times z
to factor 4n^2-7n+3 you do
4 times 3=12
what 2 numbers multiply to get 12 and add to get -7
the numbers are -3 and -4 so
split up the -7
4n^2-4n-3n+3
group
(4n^2-4n)+(-3n+3)
undistribute
(4n)(n-1)+(-3)(n-1)
reverse distributive property
ab+ac=a(b+c)
(4n-3)(n-1)=0
set each to zero
4n-3=0
add 3 to both sides
4n=3
divide both sides by 4
n=3/4
n-1=0
add 1 to both sides
n=1
n=3/4 or 1
Answers
explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!
27 = L - M
27 = 10M - M
27 = 9M
M = 3
L = 10M = 10(3) = 30

Answers
The distance formula is expressed as square root of the square of the difference of y's and the square of the difference of x's.
In 1) d = square root of (11-8)^2 + (12-8)^2 d = 5
In 2) d = square root of (9+6)^2 + (3+2)^2 d = 5 square root of 10 d = 15.81
Answer:
1.
option B is correct
2.
Option A is correct.
Step-by-step explanation:
Using distance formula:
1.
Given the points:
(8, 8) and (12, 11)
then;
Therefore, the distance between the two points is, 5 units.
2.
Given the points:
(-2, -6) and (3, 9)
then;
Therefore, the distance between the two points is, 15.8 units

1) he makes 1st shot + he makes 2nd shot
P(A) = 0.4 · 0.4 = 0.16 ( 16 % )
2) he makes 1 st shot + he misses 2nd shot
P(B) = 0.4 · 0.6 = 0.24 ( 24 % )
3) he misses 1st shot and he has no more attempts
P (C) = 0.6 ( 60 %)
0.16 · 2 + 0.24 · 1 + 0.6 · 0 = 0.32 + 0.34 = 0.56
The expected value is 0.56 points.
.56 is the answer....
