Answer:
Part a) The area of the composite figure is
Part b) The area of the triangle is
Step-by-step explanation:
we know that
The area of the composite figure is equal to the area of rectangle plus the area of triangle plus the area of trapezoid
Step 1
Find the area of rectangle
Step 2
Find the area of triangle
Step 3
Find the area of trapezoid
Step 4
Find the area of the composite figure
Answer:
y=2x+1
Step-by-step explanation:
using the slope-intercept formula y=mx+b:
y states it is simply a line, nothing to find here
m•x states the slope, or rate of change
b states the y-intercept, or where the line intersects the vertical line on thr graph, y.
SO with this info:
we can find the slope by choosing <em>any</em> two points. for my example i choose (0,1) and (2,5). the distance between the two is up +4 units (can also be found with 5-1=4). the distance also moves right +2 units (can also be found with 2-0=0). this gives up a fraction of y (up/down) ÷ x (left/right). in other words, its a fraction of 4/2, which can be reduced to 2/1, which is the same thing as 2. our slope is 2.
to find our y-intercept we simply need to find where our bold line with arrows meets our bold vertical line with arrows named y. that point is at (0,1) and since we're only looking for the y point we only need the y point, which is 1. our y-intercept is 1.
that's all. much love :)
<h3>
Answer: D) 4.25</h3>
====================================
Work Shown:
x - 3.4 > 17/68
x - 3.4 > 0.25
x - 3.4 + 3.4 > 0.25 + 3.4 .... add 3.4 to both sides
x > 3.65
Any number larger than 3.65 will work in place of x
Choice A does not work since 3.4 is not larger than 3.65
Choice B and choice C is the same story as well since 21/68 = 0.3088 approximately
Only choice D is larger than 3.65
Answer:
B is 4 because there is no other one digit number that is a common multiple of 4
