If k-9=12 then
K= 21
I think you wrote the equation wrong since it doesn’t match any of the answer choices
Answer:
y = - 1x -3
Step-by-step explanation:
First you want to find the slope. you do this by dividing the change in y by the change in x.
8-1/-3-4
when you do this you get 7 over -7. therefore, the slope would be -1.
next, you want to plug this into a point-slope equation.
y-y1=m(x-x1)
y-1=-1(x-4)
now you simplify this equation into a slope intercept equation
y-1=-1(x-4)
at 1 to each side, and distribute the -1
y=-1x-4+1
simplify
y=-1x-3
1) 1,098
2) 123.3 OR 7,000
Answer:
I've attached an image showing the intersection and the angle.
Answer:
C: They are complementary
Step-by-step explanation:
We can see from the image that angle 1, angle 2 and 90° are on a straight line. We know that sum of angles on a straight line is 180°. Thus;
∠1 + ∠2 + 90° = 180°
Rearranging, we have;
∠1 + ∠2 = 180° - 90°
Thus;
∠1 + ∠2 = 90°
Now, from angle proofs in trigonometry, it states that If the non-common sides of two adjacent angles add up to 90°, then it means that the angles are complementary.
In our problem here, sum of ∠1 and ∠2 equals 90°. Also, they are the non-common sides of 2 adjacent angles. Thus, we can say that they are complementary.
Step-by-step explanation:
Answer:y=1
x=4
Step-by-step explanation:
Since we know that y=x-3 and y=1/2x+1 we know that 1/2x+1= x-3
so know we can just simplify and evaluate the equation like this:
x-3= 1/2x +1
-1/2 -1/2
1/2x-3=-1
+3 +3
1/2x=2
x=4
now lets subsititute
y=4-3
y=1
Hope it helps tell me if it's wrong in the comments.
