Is there a picture of the question?
Iit is the first choice where it says the side length of the white square is b -a....
Answer:
Step-by-step explanation:
Let's substitute the first equation into the second one.
- Multiply by 
and bring all the terms to one side.
I'll use my graphical calculator to solve this but you could factor:
(All rounded to 2 decimal places)
Now we can substitute these values into an equation for 
.
Answer:
a = 4 b = 5
Step-by-step explanation:
8a + 12b = 92......eqn 1
6a - 4b = 4......eqn 2
multiply eqn 2 by 3
18a - 12b = 12.....eqn 2
add eqn 1 and 2 to eliminate b
26a = 104
a = 4
put a = 4 into eqn 2
18(4) - 12b = 12
72 - 12b = 12
72 - 12 = 12b
60 = 12b
5 = b
Answer:
3/4
Step-by-step explanation:
To find the slope using a line on a graph, calculate the difference between two points. To do so, use the formula y2 - y1/x2 - x1.
Two points on this line are (0, -1) and (4, 2). This means:
y2 = 2
y1 = -1
x2 = 4
x1 = 0
Plugging those values in, we get:
2 - (-1)/4 - 0
Evaluating 2 - (-1) and 4 - 0, we get 3/4. Therefore, the slope is 3/4.
