5.2 or 4.6 but it is actually 1.4
Answer:
7/540
Step-by-step explanation:
21/60= 7/20 and then you flip the fraction that is dividing the fraction so, 7/20 x 1/27= 7/540
Answer:
x + x / 2 = -7 + -2 / 2 = -4.5
y + y / 2 = -10 + -5 / 2 = -7.5
Step-by-step explanation:
M= (-4.5 , -7.5)
Answer:
The zeros of the given function
is
are -8 and -9.
Step-by-step explanation:
Given : Function ![f(x)=x^2+17x+72](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B17x%2B72)
We have to find the zeros of the functions.
Consider the given Function ![f(x)=x^2+17x+72](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B17x%2B72)
Since, we have to find the zeros of the given functions.
Put f(x) = 0
Thus, ![x^2+17x+72=0](https://tex.z-dn.net/?f=x%5E2%2B17x%2B72%3D0)
We can solve the given equation using middle term splitting method.
17x can be written as 8x + 9x
can be written as ![x^2+8x+9x+72=0](https://tex.z-dn.net/?f=x%5E2%2B8x%2B9x%2B72%3D0)
Taking x common from first two term and 9 common from last two terms, we have,
![x(x+8)+9(x+8)=0](https://tex.z-dn.net/?f=x%28x%2B8%29%2B9%28x%2B8%29%3D0)
Simplify, we have,
or ![(x+9\right)=0](https://tex.z-dn.net/?f=%28x%2B9%5Cright%29%3D0)
x = -8 and x = -9
Apply zero product rule,![a\cdot b= 0 \Rightarrow a=0 \ or \ b=0](https://tex.z-dn.net/?f=a%5Ccdot%20b%3D%200%20%5CRightarrow%20a%3D0%20%5C%20or%20%5C%20b%3D0)
![\left(x+8\right)\left(x+9\right)=0](https://tex.z-dn.net/?f=%5Cleft%28x%2B8%5Cright%29%5Cleft%28x%2B9%5Cright%29%3D0)
Thus, The zero of the given function
is
are -8 and -9.
Use the co‐interior rule, corresponding angle rule, alternate angle rule and vertical opposite angle rule to solve the question above.
angle G5 = angle K1 reason : corresponding angles
angle J1 = angle H3 reason: vertical opposite angles
angle J2 = angle K4 reason: vertical opposite angles
angle G5 = angle K4 reason: co‐ interior angles
angle F6 = angle K4 reason: alternate angle
