Answer: He added 4 to a negative 42 and said it was 46 but its supposed to simplify to -38. X=3/5
Answer: The slope is 1
Step-by-step explanation:
y2-y1/x2-x1 is the equation to find slope
plug in the numbers and you get: 6-9/1-4
that equals -3/-3 which can be simplified to 1
The x-intercept of the linear equation is the value of x when y is equal to zero. From the given equation above,
y = 0.33x
When y is zero,
0 = 0.33x ; x = 0
When y is zero, x is also zero. This means that the school will not receive any amount when they are unable to sell anything.
Answer:
The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches
