3. y-intercept is when x=0, so 2. Slope is change in y divided by change in x, so 4/3, which rounds to 1.3.
4. the equation: y=mx+d, so substitute m for the slope and d as the y-intercept, so you get y=1.3x+2
5. When you look at the graph, when x=7, then y=80. So the student may get an 80.
Answer:
18
Step-by-step explanation:
Supplementary angles means sum of angles is 180.
4x + 4 + 6x - 4 = 180
4x + 6x + 4 - 4 = 180
10x = 180
x = 180 / 10
x = 18
Answer:
the answer
the ratio x:y is 25:18
Step-by-step explanation:
we know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
Answer:
(fog)(x) = 1/(x-2) + 3
Step-by-step explanation:
f(x) = 1/x² +3 g(x) = √(x-2)
(fog)(x) = f(g(x)) = f( √(x-2)) = 1/(√(x-2))² +3
(fog)(x) = 1/(x-2) + 3
Answer: 18 cm^2
Step-by-step explanation:
There are four equal triangle and a rectangle.
Formula of a rectangle = b * h = 2*3 = 6
Formula of triangle = but there four of them so we times them by 4, this leaves us with 2 (b * h) = 2(2*3) = 12
Area of pentagon = area of all triangles + rectangle
Area of pentagon = 12 + 6 = 18
Hope this helps.
