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
10 to the second power is 100.
22.94 times 100 = 2294
The answer is 2294

Answer:
Easy the pixel turns into %.
Step-by-step explanation:
For example 100x100 image is representet in 100%x100%.
Each 1px in this case is equal to 1%.
The starting equation is
100=S+D+K
S is for Sarah, D is for Dave, and K is for Kate
This is what we know:
S=15+D
and
K=D-5
Now that we know how to find the values of everything, we must plug it in.
100=(15+D)+D+(D-5)
Combine like terms.
100=10+3D
Subtract 10 to isolate variable.
90=3D
Divide by 3 to isolate variable.
30=D
Plug in number to find the answers.
Answer:
Sarah worked for 45 hours
Dave worked for 30 hours
Kate worked for 25 hours
> and = with line through it
