Answer:
Step-by-step explanation:
-5(2k+4)+1=13-6k
Expanding the brackets.
-10k-20+1=13-6k
-10k-19=13-6k
Adding 6k and 19 on both sides.
-10k+6k=13+19
-4k=32
Divide both sides by -4.
k = -8
Answer:
its a right angle!

Answer:
B and C
Step-by-step explanation:
In order to know your x and y intercept, first rearrange your equation in the form ax+by=c
<u>NB </u> c should always be one so if you rearrange and c is not one, divide the whole equation by the no. represented by c, then to know your x and y intercepts look at the reciprocal of the coefficients of x and y
For example
B. -4x+2y= -6
divide the whole equation by -6 to get
2/3x-1/3y=1
hence the x intercept will be the reciprocal of the coefficient of x which is 3/2
y intercept will be the reciprocal of the coefficient of y which is -3
so if you look at the line, the equation applies
The same will apply to C
The answer is 1/3x + 2/4 .
Answer:
200%
Step-by-step explanation:
If $40 is 100% then multiply it by 3 to get $120
