Is 2y-4=10 a function
2 answers:
Answer:
No, is not a function.
Step-by-step explanation:
To find : Is a function ?
Solution :
A function is defined as a relation between sets that associates to every element of a first set exactly one element of the second set.
or relation between input and output.
i.e. f(x)=2x
Where, x is the input and 2x is the output.
We have given, is not a function because it is not a representation of function.
The given expression is an equation as there is only one variable defined as a constant.

Answer:
Step-by-step explanation:
1). Equation of a line which has slope 'm' and y-intercept as 'b' is,
y = mx + b
If slope 'm' = 1 and y-intercept 'b' = -3
Equation of the line will be,
y = x - 3
x - y = 3
2). Equation of a line having slope 'm' and passing through a point (x', y') is,
y - y' = m(x - x')
If the slope 'm' = 1 and point is (-1, 2),
The the equation of the line will be,
y - 2 = 1(x + 1)
y = x + 1 + 2
y = x + 3
x - y = -3
3). Equation of a line passing through two points and
will be,
If this line passes through (-2, 3) and (-3, 4),
y - 3 = -1(x + 2)
y = -x - 2 + 3
y = -x + 1
x + y = 1
Answer:
<h2>PR' = 12units</h2>Step-by-step explanation:
When a figure is dilated, it means there is a transformation carried out on the figure. The dilation may cause the figure to increase or reduce in size depending on the dilation factor.
<u>If the dilation factor of an object is greater than 1, the resulting image will be a magnified image otherwise, it will be a diminished image. </u>
Given the dilation factor in question DP to be 4, this means that the new image formed will be 4times bigger than the original.
According to the diagram, side PR = 3, if this is dilated by factor of 4, the side PR' will be equal to 4*PR
PR' = 4 * PR
PR' = 4*3
PR' = 12units
