Answer:
x-2y=4
Step-by-step explanation:
So from the question we know the following:
When something is x intercept it means y=0 so we have (4,0)
When something is y intercept it means x=0 so we have (0,-2)
Now you use these to find the slope using the formula m= (y2-y1)/(x2-x1)
Plug in the values
m= (-2-0)/0-4)
m=(-2/-4)
m= 1/2
x-2y=4
Now you just plug this in slope intercept form y=mx+c, where c is y intercept
y=1/2 x -2
Standard form: ax+by=c
y=1/2 x -2 (rearrange to match the above equation)
-1/2 x +y =-2 (multiply both sides by 2 because we can't have a fraction for a in the standard form)
-1x+2y=-4 (now multiply both sides by -1 because a cannot be negative)
x-2y=4
I'm horrible at this so I'm just guessing.
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) <span>≥ 45 is the answer I got.
The answer to that inequality would be
X </span><span>≥ 7 I think.</span>
1. Find the perimeter of the square then the circumference of the circle then subtract the circle from the square.
Area of square=length of side squared=9.8^2=96.04.
Area of circle=(pi*radius)^2=((22/7)*(9.8/2))^2
2. Area of circle=pi*r squared
38.5=((22/7)*r)^2
Solve for r
Square root of 38.5/(22/7))=r
calculate area using above formula
Answer:
Use a graphing calc.
Domain: All real numbers
Range: (negative infinity, 10.45]
Step-by-step explanation:
Using PEMDAS
P = 1x1+9x(0.01)+1x(0.001)
E = no change
M = 1+0.09+0.001
D = no change
A = 1.091
S = no change
final answer is 1.091
