Answer:
ANSWER is B. look at the sides and simplified.
So here's how to do it,
slope intercept form is y=mx+b
m is the slope, b is the y- intercept, X is your unknown variable.
you need to solve to get y by its self to get your slope.
for perpendicular lines flip the slope
ex 1, smy=2x+6 --- slope of a perpendicular line will be 1/2
ex 2, y=3/2+8 ---8 perpendicular lien would have a slope of 2/3
parallel lines have the same slope so any equation with with the same slope will be parallel if it has the same degree.
ex. y=2x+14 is parallel to y= 2x+56
slope can be found using the following formula if you have two sets of points on the same line
m= y2-y1 ÷ X2 - X1
Answer:
$25.25-lasagna, $12.25-garlic bread
Step-by-step explanation:
5L+3G=163
- 4L+4G=150
______________
4(5L+3G=163)
-5(4L+4G=150)
_____________
20L+12G=652
-20L-20G=-750
_____________
-8G=-98
-8G/-8 = -98/-8
G=$12.25
now plug that into G in any of the 2 equations at the top and you can solve for L(price of lasagna)
