Question 11
x+x+1/2x+1/2x=360
x+x+2/2x+=360
x+x+x=360
3x=360
x=120
Then substitute 120 in the place of x
x1=120
x2=120
1/2(120)=60
1/2(120)=60
To check your answer you can add 60+60+120+120 the should be equal to 360
Question 12
x+x+(x-45)+(x-45)+(x-45)=540
x+x+x-45+x-45+x-45=540
5x-135=540
5x=540+135
5x=675
x=675/5
x=135
Then substitute 135 in the place of x
x1=135
x2=135
135-45=90
135-45=90
135-45=90
To check your answer you can add 135+135+90+90-90 the should be equal to 540

Answer: y = -2/3x + 5
Step-by-step explanation: you find the slope by finding “rise/run”. the rise is -2, and the run is 3, so the slope is -2/3. the y intercept is 5
1 zero pair of 25 was added to bring given function into vertex form.
<h3>What is a Zero Pair ?</h3>
A zero Pair is the set of two numbers which when added together gives 0.
The function given is
f(x) = x² -10x -4
To convert it into the vertex form
y = a(x-h)² +k
f(x) = x² -10x +25 -25 -4
f(x) = x² -10x +5² -25-4
f(x) = (x-5)² -29
Therefore this is the given function's vertex form and
1 zero pair of 25 was added to bring it into that.
Therefore Option D is the answer.
