Answer:
x = -2/3
Step-by-step explanation:
Step 1: Convert signs
f(x) = -(-3x) + 4
f(x) = 3x + 4
Step 2: Set f(x) and g(x) equal to each other and solve for <em>x</em>
3x + 4 = 2
3x = -2
x = -2/3
And we have our final answer!
Answer: No
Step-by-step explanation: If you mean 3^-2 it would be 0.111111111 repeating. 3^2 is 9 not -2
1.23÷10 = 0.123 is a true statement

The height of building is 35 feet
<em><u>Solution:</u></em>
Given that,
Sam is 6 feet tall and his shadow is 3.6 feet tall
The shadow of building is 21 feet long
<em><u>To find: height of building</u></em>
We can solve this by setting up a ratio comparing the height of the building to the height of the Sam and shadow of the building to the shadow of the Sam
Let us consider,
= height of building
= height of Sam
= shadow of building
= shadow of Sam
Therefore,
Substitute the values,
Thus height of building is 35 feet
Answer:
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. ... The solution to the system will be in the point where the two lines intersect.
