Answer:
find the area of the triangle: 5*4=20 divided by 2 is 10.
split the second figure into a rectangle and triangle: 2*5=10 and 5*5 divided by 2 is 12.5
12.5+10+10=32.5
32.5
Answer: The slope of the line a is 3/4
Step-by-step explanation:
1. The equation of the line has the following form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where m is the slope and b is the y-intercept.
2. As you can see in the graph attached, the line intersect the y-axis at 1, therefore:
b=1
3. So, to calculate the slope, susbtitute: the value of b into the equation of the line and any point of the line and then solve for the slope:
Let's pick the point (4,4), then the slope is:
![4=m(4)+1\\4-1=4m\\3=4m\\m=\frac{3}{4}](https://tex.z-dn.net/?f=4%3Dm%284%29%2B1%5C%5C4-1%3D4m%5C%5C3%3D4m%5C%5Cm%3D%5Cfrac%7B3%7D%7B4%7D)
Answer:
x = -4 or 3
Step-by-step explanation:
+ 6x - 2 = -
+ 4x + 22
2
+ 2x - 24 = 0
+ x - 12 = 0
(x + 4)(x - 3)=0
x = -4 or 3
