Answer:
111.6 cm
Step-by-step explanation:
The area of a triangle can be calculated using the following formula:
Area = (base x height) / 2
Using this formula we can solve this problem in the following way:
- We know base = 12.4, and height = 18
- (12.4 x 18) / 2 = 111.6
Hope this helps!!
6r+7=13+7r
Move 7r to the other side. Sign changes from +7r to -7r.
6r-7r+7=13+7r-7r
6r-7r+7=13
-r+7=13
Move +r to the other side. Sign changes from +7 to -7.
-r+7-7=13-7
-r=6
Multiply by -1 to get positive and for 6
-r(-1)=6(-1)
r=-6
Answer: r=-6
10 x 4 = 40. This should help with the first one.
Answer:
y = -2x - 2
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -2
so now the equation is y = -2x + b
from here, what you could do to find b is...
plug (-2, 2) into the equation
1) x = -2, y = 2
2) 2 = -2(-2) + b
3) 2 = 4 + b
4) -2 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -2)
so "b" would be equal to -2
this makes the final equation y = -2x + (-2) or y = -2x - 2
