Answer:
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form:
where 
is the slope and 
is the y-intercept (the value of y when the line intercepts the y-axis)
<u>1) Find the slope of the line (m)</u>
The equation for slope: 
when the given points are 
and 
Plug in the given points (3,1) and (6,3)
Now, plugging this back into , our equation looks like this:
<u />
<u>2) Find the y-intercept of the line</u>
To find the y-intercept, we take the equation that we have so far and plug in any given point to solve for b. For example, we can use the point (3,1):
Subtract both sides by 2 to isolate b
<u>3) Plug m and b into y=mx+b</u>
I hope this helps!
Answer:
Step-by-step explanation:
A. x^2+3x=4
x=1, -4
B. (2x+3)(x-4)(x+4)=0
x= -3/2, 4, -4
Answer:
The mistake is in step 1 when you do -2(x+4) you do the distributive property first -2 times x is -2x that's correct but -2 times 4 is not 8 it is -8
when you multiply by negatives the answer will always be a negative unless your multiply 2 negative number together then itll be positive ex. 4 × -4 = -16 (negative) but -4 × -4 = 16 (positive)
27 weeks minimum.
To get this, I divided 520 and 20. It equals 26, but there are still 5 dollars left. She cannot buy the bracelet without them, so you must add on 1 more week.
Good luck!
