There are many ways to do this, if you wanted to write a numerical expression for: Lauren had $7 she babysits for three hours and earned $8.50 per hour, you would write 7+3x8.50=M. It is much shorter and makes much more sense to write this expression than to write a whole story
We need a slope of -1/2
2x + 4y = 1
4y = -2x + 1
y = -2/4x + 1/4
y = -1/2x + 1/4...slope of -1/2
so the answer is 2x+4y=1
Well there is 1 girl for every 5 boys so you could add 1 + 5 to get 6, and divide the total students by 6 to get 38 girls.
Answer:
option D
Step-by-step explanation:
Answer:
y = 2x + 12
Step-by-step explanation:
Get the standard form equation into y = mx + b form.
Then, use the recipricol of the m value to get the slope for the perpendicular line.
Then, plug in the point and solve for the b value.
Work :
y = -1/2x-5/4
Perpendicular line slope : 2
y = 2x + b
-4 = 2(-8) + b
-4 = -16 + b
b = 12
y = 2x + 12
