Answer:
y = m x + b equation of straight line
Slope = (y2 - y1) / (x2 - x1) = (-3 - 1) / ((7 - (-5)) = -4 / 12 = -1 / 3
y = -x / 3 + b since m is defined above
lf y = 7 then x = -5 given
7 = 5/3 + b
b = (21 - 5) / 3 = 16 / 3 = 5 1/3
y = -x / 3 + 5 1/3
Check: Use point x = -5
y = 5/3 + 16/3 = 21 / 3 = 7 correct
Answer:
y = 50
Step-by-step explanation:
y / 5 = 10
Multiply each side by 5
y/5*5 = 10*5
y = 50
X10+2y=50 pounds this is your answers because if you do 3 times what number is less than 50 but still is even because all you have afterwars are 10 so 10 is 30. then 30 +?=50 its 20 so 10 multply by two plus 3 multiply by 10 equals 50. hope this helps!!!!!!!!!!
The number of real solution of the system y = and y = 3x - 2 is zero
The system of equations are
y =
y = 3x - 2
Then the equation will be
= 3x - 2
Move 3x - 2 to the left hand side of the equation
- 3x + 2 = 0
Find the value of - 4ac
Here value of a = 3
The value of b = -3
The value of c = 2
Substitute the values in the expression
= - 4×3×2
= 9 - 24
= -15
Here the value of - 4ac is -15
Therefore there is no real valued solution
Hence, the number of real solution of the system y = and y = 3x - 2 is zero

Answer:
The measurement justifies the perpendicular bisector theorem
Step-by-step explanation:
Mathematically, what the theorem is saying is that the distance AC is the same as the distance BC
This is because. the line joining both points is coming from the same external point which is on the bisector of the line joining the two points.
Hence, what we are sayingg here is that the lines coming from the point C which is a point on the perpendicular bisector of the line segment AC is equal for both end points on the line segment.
Thus, by measuring both lines, we can see that they are congruent and the triangle we have is an isosceles triangle
