Answer:
y = -1/2 x + 2
Step-by-step explanation:
Which of the following equations describes the line shown below? Check all
that apply.
(-4, 4)
(2, 1)
The standard equation of a line is y = mx,+b
m is the slope
b is he y-inttercept
Get the slope
Slope m = y2-y1/x2-x1
Substitute the coordinate
M = 1-4/2-(-4)
M = -3/6
M = -1/2
Substitute m= -1/2 and (2,1) into y = mx+b
1 = -1/2(2)+b
1 = -1+b
b = 1+1
b=2
Get the equation
Recall y =mx+b
y = -1/2 x + 2
31.7 + 42.8 + 26.4 + x/4 = 39.1
Add up all the plain numbers on the left side:
100.9 + x/4 = 39.1
Subtract 100.9 from each side:
x/4 = 39.1
Multiply each side by 4:
<em>x = 156.4</em>
Answer:
Step-by-step explanation:15 percent *287 = (15/100)*287 = (15*287)/100 = 4305/100 = 43.05Now we have: 15 percent of 287 = 43.05Question: What is 15 percent of 287?We need to determine 15% of 287 now and the procedure explaining it as suchStep 1: In the given case Output Value is 287.Step 2: Let us consider the unknown value as x.Step 3: Consider the output value of 287 = 100%.Step 4: In the Same way, x = 15%.Step 5: On dividing the pair of simple equations we got the equation as under287 = 100% (1).x = 15% (2).(287%)/(x%) = 100/15Step 6: Reciprocal of both the sides results in the following equationx%/287% = 15/100Step 7: Simplifying the above obtained equation further will tell what is 15% of 287x = 43.05%Therefore, 15% of 287 is 43.05
the Answer is 4 do order of operations
