Answer:
y= -4x+7
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient of the line first.
Using the above formula,
Susbt. m= -4 into the equation:
y= -4x +c
Subst. a coordinate to find c.
When x=3, y= -5,
-5= -4(3) +c
-5= -12 +c
c= 12 -5
c=7
Thus the equation of the line is y= -4x +7.
Answer:
#1: 10 bags
#2: 5 1/2 pounds
#3: 5 bags
Step-by-step explanation:
for number one you just count all the x
for number two I added all the pounds of the bags
for number 3 (im not sure if my answer was right for this one) theres only 5 x's on 1/2. so I think the answer is 5.
180 is the LCM of the three numbers
Answer:
The Answer is D.
Step-by-step explanation:
You just need to plug in x for the first few, if it doesn't match go to the next option.
I tried this and figured out it's d in less than a minute.
Yes
[5.5+(-2.3)] can be rearranged to be 5.5-2.3. It will be 3.2
(-5.5+2.3) can be rearranged to be 2.3-5.5. It will be -3.2
3.2-3.2=0
