Answer:
y = x + 3 is red line.
y = -3x-2 is green line.
y = -x-7 is black line.
y = 2x + 1 is blue line.
Step-by-step explanation:
first we look at up on both and y intercepts
then find a line.
y = x + 3
x intercept is : x + 3 = 0 so x = -3
y intercept is : 0 + 3 = 0 so y = 3
y = -3x-2
x intercept is : -3x-2 = 0 so x = -2/3
y intercept is : -3*0 -2 = 0 so y = -2
y = -x-7
x intercept is : -x -7 = 0 so x = -7
y intercept is : 0 -7 = 0 so y = -7
y = 2x+ 1
x intercept is : 2x+1 = 0 so x = -1/2
y intercept is : 0*2 + 1 = 0 so y = 1
therefor :
Answer:
y = x + 3 is red line.
y = -3x-2 is green line.
y = -x-7 is black line.
y = 2x + 1 is blue line.
(A)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
v=3
w=−7

Answer:
36 units
Step-by-step explanation:
Split the parallelogram into 3 shapes. Two right triangles and one rectangle.
Find the length of all the sides.
Triangle one: Triangle two:
Leg 1: 8 a^2+b^2=c^2 Leg 1: 8 a^2+b^2=c^2
Leg 2: 6 8^2 + 6^2 = c^2 Leg 2: 6 8^2 + 6^2 = c^2
Hypotenuse: ? 64 + 36 = c^2 Hypotenuse: ? 64 + 36 = c^2
100=c^2 100=c^2
c=10 c=10
Hypotenuse One: 10 units
Hypotenuse Two: 10 units
Base One Length: 8 units
Base Two Length: 8 units
Add all these numbers up and your answer would be 36 units.
Answer:
In terms of the class, the dot product represents the weighed class average.
Step-by-step explanation:
The two vectors are:
- The weight of each of the semester's exams.
In decimal:
- The class average on each of the exams
In decimal:
-----------------------
Dot product:
Suppose there are two vectors, u and v
u = (a,b,c)
v = (d,e,f)
There dot product between the vectors u and v is:
u.v = (a,b,c).(d,e,f) = ad + be + cf
------------------
So
In terms of the class, the dot product represents the weighed class average.
