Answer:
.
Step-by-step explanation:
The relation between variable x and y is linear as the increase of y with respect to x is uniform.
That means the slope of the graph obtained from plotting the points on the coordinate plane is constant and it can be obtained by taking any two pairs of points.
Now, the equation of this straight line graph can be obtained from any two pairs of the given points.
Let us assume the points are (1,5) and (5,10)
Therefore, the required equation of the straight line is

Answer:
b⁶
Step-by-step explanation:
The question tells you how to work it: use the relations you studied.
Here, you have the power of an expression with an exponent. The exponents multiply.

<em>Additional comment</em>
A coefficient is used to indicate repeated addition: 3x = x + x + x.
An exponent is used to indicate repeated multiplication: x³ = x·x·x.
This is still true when the exponent is applied to an expression with an exponent:
(b³)² = (b³)(b³) . . . . the factor b³ is repeated 2 times as indicated by the exponent 2
Of course, each of these indicates repeated multiplication, so we really have ...
(b³)(b³) = (b·b·b)·(b·b·b) = b·b·b·b·b·b
And this can be simplified using an exponent to show the repeated multiplication:
= b⁶
Then, by going the long way around, we arrive at ...
(b³)² = b⁶
Answer:
(7u+1)(2u-5)
Step-by-step explanation:
miltiply the coefficient of u² and the integer -5 = -70
from basic intuition: factors are -35 and +2
(which when added gives -33 and multiplies to give 70)
14u² -35u +2u -5
7u(2u-5) +1(2u-5)
(7u+1)(2u-5)
