Answer:
<span>x=9</span>
Explanation:
Substitute the y value:
<span>2x+<span>(3⋅6)</span>=36</span>
<span>2x+18=36</span>
Subtract 18 from both sides to isolate the <span>2x</span>:
<span>2x=36−18</span>
<span>2x=18</span>
Divide both sides by 2 to get x on its own:
<span>x=<span>182</span></span>
<span>x=9</span>
Thus, we have our answer.
Let's see by using the Pythagorean theorem.
3 and 4 are legs. 3 is the shortest leg.
7 is the hypotenuse.
The theorem states that:
a² + b² = c²
a = 3
b = 4
c = 7
3² + 4² = 7²
9 + 16 = 49
25 = 49 (Incorrect)
So it is not possible for 3,4,7 to be a right triangle.
Answer:
x=-40
Step-by-step explanation:
1)Moe variable to the left hand side and change its sign 0.1x-0.15x=8-6
2)collect like terms 0.05x=2
3)Divide both sides by "-0.05"
4) x=-40
Answer:
The slope is -4
