Given a funtion in slope-intercept form:
y=mx+b
m=slope or rate of change.
b=y-intercept.
In tyis funtion:
y=4-5/8 x
y=-5/8 x+4
m=is the number beside "x"=-5/8
Therefore:
the rate of change of y respect to x will be -5/8.
Make the two equations equal together and solve for x
(x/3) = -2x+7
multiple both sides by 3
x=-6x+21
solve for x
7x=21
x=3.
now plug in 3 into one of the equation to find your y value.
y=-2(3)+7
y=1
write your answer as a coordinate; (3,1)
Answer:
The relationship is proportional ✧
Let
x------> Cathy's<span> ages
</span>y------> Tony's ages
we know that
x+y=65-----> x=65-y-----> equation 1
y-8=(2/5)*(x-8)-----> equation 2
substitute equation 1 in equation 2
y-8=(2/5)*(65-y-8)---> y-8=22.8-0.4y----> y+0.4y=22.8+8
1.4y=30.8-----> y=22
x=65-y-----> x=65-22----> x=43
the answer is
Cathy's ages is 43 years
Tony's ages is 22 years
The <em><u>correct answer</u></em> is:
C.the point of concurrency of the angle bisectors of the triangle
Explanation:
The largest circle that can be drawn inside a triangle is called an inscribed circle. The center of this circle is called the incenter.
The incenter is formed by the intersection of the angle bisectors of all 3 angles in the triangle.
