Answer:
n = 4
Step-by-step explanation:
Given
10n + 2 = 7n + 14
Collect terms in n on the left side and numbers on the right side
Subtract 7n from both sides
3n + 2 = 14 ( subtract 2 from both sides )
3n = 12 ( divide both sides by 3 )
n = 4
Answer:
-1
Step-by-step explanation:
we would use the slope formula which is y2-y2/x2-x1
so 3-4/5-4= -1
Answer:
Solutions are -10 and 26
Step-by-step explanation:
( - the abolute sign I'm using
( x - 8 ) + 2 = 20
( x - 8 ) = 18
x - 8 = 18 (postive case)
x - 8 + 8 = 18 + 8
x = 26
( x - 8 ) = 18
x - 8 = -18 (negative case)
x - 8 + 8 = -18 + 8
x = -10
Answer:
Step-by-step explanation:
It is known that,
<em>'Vertical stretch, stretches the function up and down towards the y-axis'.</em>
The general form of vertical stretch is given by 'kf(x)', where k>1 is the factor by which function is stretched.
As, we have the function 
which is stretched by a factor of 4.
Thus, the new function will be .
Hence, the equation for the vertical stretch is .
<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a²x(-3b²)x2c. Note that 5, -3 and 2 are
coefficients and a², b² and c are variables. Multiply first the coefficients 5, -3
and 2 and you get -30. Always remember that in multiplying numbers, especially
variables, the base of the exponent must be equal. However, you have variables
of a²,
b²
and, c. You cannot multiply or add them because they are different. So the
answer is -30a² b²c.</span>
