First option: 14.0 cm^2
Area of semicircle + area of triangle
1/2(pi)(r^2) + 1/2(b)(h)
1/2(3.14)(1.5^2) + 1/2(3)(7)
3.53+ 10.5
14.03 cm^2
Step (1) Flip the equation
−10x+6=y
Step (2) Add -6 to both sides
−10x+6+−6=y+−6
−10x=y−6
Step (3) Divide both sides by -10
−10x−10=y−6−10
ANSWER
x-3y= 1
The equation needs to be rewritten in proper Slope intercept form ( y = mx+b) where m is the slope and b is the y-intercept.
x-3y = 1
Subtract x from each side:
-3y = 1-x
Divide both sides by -3:
y = 1/-3 - x/-3
Simplify:
y = 1/3x - 1/3
The slope is 1/3
The length of hypotenuse of an isosceles right triangle with two equal legs each 4 cm is given by Pythagorean theorem as follows.
√42+42.
=√32.
=4√2.
4√2 cm.
