Answer:

Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
The product of the gradients of perpendicular lines is -1.
Gradient of given line= 3.
(Gradient of line)(3)= -1
3m= -1
m= 
subst. m=
into the equation:

To find the value of c, substitute a coordinate.
When x=0, y=4,

Thus the equation of the line is
.
Answer:
You need to find the volume in two parts then add them together, think of the shed as box and a rectangular prism.
Volumebox=length x width x height
Volumeprism=1/2 x base of triangle x height of triangle x length

Answer:
12
Step-by-step explanation:
You set up cross multiplication 3/4 x 9/x, you go 4x9=36 divided by 3 equals 12
To start off, 5+7=12, so we already know how the number line will be laid out. We will have Point A on 5, and count up 7 units, plotting Point B on 12.
Answer:
Step-by-step explanation:
y
=
x
2
+
91
Explanation:
Let the number be x
, then Square of the number is x
^2
91 more than the square of a number" will be x^
2 + 91
So, we can write it as an algebraic expression with two variables as :
y
=
x
^2 + 91
