The coordinates plane is illustrated below.
<h3>How to illustrate the information?</h3>A coordinate plane simply means the graphing system for points and lines.
Based on the information given, the area of teb triangle will be:
= 1/2 × b × h
= 1/2 × 11 × 20
= 110

Answer: Option B
B.
Step-by-step explanation:
We have the following equations:
(1)
(2)
Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.
Then we must multiply the number "a" by a value z such that when adding the result is zero.
So
We solve the equation for z
The first equation must be multiplied by a value of
Answer:
a=1.5, b= 3
Step-by-step explanation:
sum of all sides will give us perimeter. Therefore
2a+b+6a+2b+1+4a=28
12a+3b+1=28
12a+3b=27....eqn1
since t two sides of this isosceles triangle are equal:
2a+b=4a
2a=b
substituting in the first equation whenever we encounter a we will have:
6b+3b=27
9b=27
b=3
therefore
