Answer:
real , rational and integer
Step-by-step explanation:
it is an integer because all the negative numbers and positive numbers belong to the group integers
it is a rational number because rational numbers are divided into 3 groups which are natural numbers , whole numbers, and integers
it is a real number because real numbers are divided into two rational and irrational numbers
number system
real numbers imaginory numbers
rational numbers irrational numbers
whole numbers ,natural numbers, integers
Given:
The coordinates of point A are (7,4).
It is dilated from the origin by a scale factor r = 3.
To find:
The coordinates of A'.
Solution:
If a figure is dilated from the origin by a scale factor k, then
Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:
Using this rule, we get
Therefore, the coordinates of point A' are (21,12).
Answer:
- 3, -2. -1 , 0 , 1, 2, and 3
when it looks like that it means that it is less then 3
Answer:
y= ab if a≠b
Step-by-step explanation:
y/a −b= y/b −a
multiply each side by ab to clear the fractions
ab(y/a −b) = ab( y/b −a)
distribute
ab * y/a - ab*b = ab * y/b - ab *a
b*y - ab^2 = ay -a^2 b
subtract ay on each side
by -ay -ab^2 = ay-ay -a^2b
by -ay -ab^2 =-a^2b
add ab^2 to each side
by-ay -ab^2 +ab^2 = ab^2 - a^2b
by-ay = ab^2 - a^2b
factor out the y on the left, factor out an ab on the right
y (b-a) = ab(b-a)
divide by (b-a)
y (b-a) /(b-a)= ab(b-a)/(b-a) b-a ≠0 or b≠a
y = ab
Answer:
.
Step-by-step explanation:
The minimun distance between a point and a plane is the perpendicular distance. The formula is
d =
where , A=4, B=3, C=1 and D=-10. So, the distance is
d =
d =
d = .
