Answer:
61 cm for each book shelf.
Step-by-step explanation:
First it gives you the width of the boxes so you add them together
132 + 108 + 94 = 334
so 334 cm has already been used out of 456 cm.
Next you will 456 - 334 = 122 cm left over
if they are building 2 book cases you with take what cm's you have left and divide it by 2
122 / 2 = 61
So that means each book case will be 61 cm's wide
Answer:
y = 4x–5
Step-by-step explanation:
Slope intercept form is y = mx +b. We can rearrange the equation to fit slope intercept form.
–2y = –8x + 10 (we get this by subtracting 8x from both sides)
In order to isolate the y, we divide both sides by –2.
=
+ 
–2 divided by –2 equals 1, –8 divided by –2 equals 4, and 10 divided by –2 equals 5.
Therefore, the answer is y = 4x–5.
a)
Add the score and then square the sum.
By using the summation notation we can write the above statement is (Σx)²
b)
Square each score and then add the squared values.
By using the summation notation we can write the above statement is Σx²
Subtract 2 point from each score and then add the resulting values.
By using the summation notation we can write the above statement is Σ(x-2)
Subtract 1 point from each score and square the resulting values. Then add the squared values.
By using the summation notation we can write the above statement is Σ(x-1)²
<h2>
The required equation of line is 2x - 3y - 9 = 0.</h2>
Step-by-step explanation:
Here, slope(m) =
and y - intercept(c) = -3
To find, the required equation of line = ?
We know that,
The equation of a line with slope m and y-intercept c is given by
y = mx + c
∴ The required equation of line
y =
x + (- 3)
⇒ y =
x - 3
⇒ y + 3 =
x
⇒ 3(y + 3) = 2x
⇒ 3y + 9 = 2x
⇒ 2x - 3y - 9 = 0
Thus, the required equation of line is 2x - 3y - 9 = 0.
