Answer:
4x + y = 13
Step-by-step explanation:
1. Change 4x + y -2=0 into slope intercept form to find the slope:
y = -4x +2 The slope is -4
2. Plug in x, y and m into y = mx + b
-3 = -4 (4) + b
-3 = -16 + b
13 + b
3. Plug m and b into equation y = mx + b
y = -4x + 13
4. Change equation into standard form:
4x - y = 13
Answer:
34
Step-by-step explanation:
let the missing value is x
(25+x) /2 = 29.5
25+x = 29.5(2)
25+x = 59
x = 59-25
x = 34
Ok so the perimeter is the sum of all four sides, in this case, 26cm. The sides are then x, x, x+5, and x+5. 26=x+x+x+5+x+5 OR 26=4x+10.
x+5=length
x=width
subtract ten from each side:
16=4x
divide both sides by four:
x=4
Now we know the width. The length is the width plus 5.
4+5=9
Length: 9cm
Width: 4cm
$6.50 x 8 = $52 which is the hourly rate for her 8 hours
Then
$0.45 x 74 = 33.3
$33.3 + $52 = $85.30
If your asking to get dead on it's the closest I came because it would be under or over the $85
