Answer:
your age is 95
Step-by-step explanation:
so what minus 400 gets you 210? 190 so you took 190 away from 400 or reduced it by 190 and got 210 but you said that it was twice your age so we can do the inverse of times 2 which is divided by 2 and you would get 95.
Answer:
I guess divide both side by l because to find w we have to eliminate l first......
Answer:
y = 9
Step-by-step explanation:
The line x = -7 is a vertical line, so the perpendicular line will be horizontal.
Horizontal lines have a slope of 0.
Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation
y = mx + b
9 = 0(4) + b
9 = b
Plug this and the slope into the equation:
y = mx + b
y = 0x + b
y = 9
So, y = 9 is the equation
To determine if 7, 8 and 13 can make a triangle, let's use Pythagorean theorem!
Pythagorean theorem: a² + b² = c²
Now plugging in our numbers: 7² + 8² ≠ 13²
Sadly, these numbers don't work. Therefore we cannot classify the triangle.
Hope this helps!
