42 divided by 6 pls give me brainlyliest
Answer:
x-intercept:
y-intercept:
Step-by-step explanation:
To find the x-intercept, substitute in for and solve for .
Simplify 2(0):
Subtract 0 - 3 = -3:
Subtract 7 from both sides:
Simplify:
Divide both sides by -4
To find the y-intercept, substitute in for and solve for .
Switch sides:
Simplify -4(0):
Add 3 to both sides:
Simplify:
Divide both sides by 2:
The slope is 0 and the equation is y = -2

Answer:
Hence when the radius is halved the area is divided by 4
2.5 inches^2
Step-by-step explanation:
Given data
Area= 10inches^2
We know that the expression for the area of a circle is given as
Area= πr^2
10= 3.142*r^2
10/3.142= r^2
r^2= 3.18
Square both sides
r= √3.18
r= 1.78 inches
Now let us half the radius and find the area of the new circle
r/2= 1.78/2
r= 0.89
Area of the new circle is
Area= 3.142*0.89^2
Area= 3.142*0.7921
Area= 2.5 inches^2
