How would I do this? What would it be?
Vinvika [58]

50

Step-by-step explanation:

Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.

therefore,

m(Angle BAE)=m(Angle EAC)

x + 30 = 3x - 10

or, 2x=40

or, x=20

Hence,

m(Angle EAC)=

3x - 10

=

(3 \times 20) - 10  = 60 - 10 = 50

F(x)-mx+ b, f(-2)=3 and f(4)=1 , what is the value of m and b
NeX [460]

Answer: m=\dfrac{-1}{3}, b=\dfrac{7}{3}

Step-by-step explanation:

Given

Function is  f(x)=mx+b

f(-2)=3

\therefore 3=m(-2)+b\\\Rightarrow b-2m=3\quad \ldots(i)

f(4)=1\\\therefore 1=4m+b\quad \ldots(ii)

from (i) and (ii) we get

m=\dfrac{-1}{3}, b=\dfrac{7}{3}

The base of a triangle is 9 inches more than 3 times the height. if the area of the triangle is 105 square inches, find the base
wolverine [178]
So to solve you need to set up equations, Using h as the height. So the base is 9 inches more  (+9)  than 3 times the height (3h) so 3h+9 equals the base. You have the area so you need to plug in the equation for the base and h for height and divide it all by 2. h(3h+9)/2=105. after you solve that and get h by itself you should get h= 7 and the b= 30
