The answer to this is C. 45.19
Answer:

Step-by-step explanation:
Answer:
D= 49/8
Step-by-step explanation:
Cross-multiply.
(2d-5)/2 = (5d+2)/9
(2d−5)*(9)=(5d+2)*(2)
18d−45=10d+4
Subtract 10d from both sides.
18d−45−10d=10d+4−10d
8d−45=4
Add 45 to both sides.
8d−45+45=4+45
8d=49
Divide both sides by 8.
d= 49/8
So the answer is 49/8
I hope it's right!
Answer:
Step-by-step explanation:
The equation of the line parallel to
y = x
has a slope of m = 1
This means that the family of lines with the same slope are of the form
y = x - (a)
where -a represents the y intercept, and (a) the x- intercept
With a = 4, the equation intercepts the x axis at x = 4
Please see attached graph
Answer:
The value of y is 4
The equation of line is y = x + 7 .
Step-by-step explanation:
Given as :
The points are
(
,
) = (- 3, y)
(
,
) = (- 9, -2)
The slope = m = 1
Now,<u> The slope is calculated in points form</u>
So, Slope = 
I.e m = 
or, 1 = 
or, 1 = 
or, 1 × (-6) = - 2 - y
or, - 6 = - 2- y
or, y = - 2 + 6
∴ y = 4
So, The new points as
(
,
) = (- 3, 4 )
(
,
) = (- 9, -2)
<u>So, the equation of line in slope - point form can be written as</u>
y -
= m ( x -
)
i.e y - 4 = ( 1 ) × ( x - (-3) )
or, y - 4 = x + 3
∴ y = x + 3 + 4
Or, y = x + 7
So, The equation of line is y = x + 7
Hence The value of y is 4
And The equation of line is y = x + 7 . Answer
