Answer:

Step-by-step explanation:
The given equation is written in the form of y=mx+c (where m is the gradient and c is the y-intercept).
Thus, gradient of given equation= -⅔
The products of the gradient of perpendicular lines is -1.
(Gradient of line)(-⅔)= -1
Gradient of line

Hence, m=
.
Subst. m=
into the equation:

To find the value of c, substitute a pair of coordinates into the equation:
When x= -4, y= 2,

Thus, the equation of the line is
.
Answer:
Step-by-step explanation:
-2x + 7(1/2) =15
-4x +7 =30
-4x =23
x=-23/4
Answer:
The mass of 100 cubic centimeters of the material would be
1,000 grams.
The mass of 500 cubic centimeters of the material would be
5,000 grams.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Graph in the picture represents,
y = qˣ
a). Point of intersection of the curve with the y-axis → (0, 1)
b). Since, this graph passes through (1, 4)
By substituting values in the equation,
4 = q¹
q = 4
c). Value of y when x = 10,

y = 1048576
