Answer:
The multiples of a whole number are found by taking the product of any counting number and that whole number. For example, to find the multiples of 3, multiply 3 by 1, 3 by 2, 3 by 3, and so on. To find the multiples of 5, multiply 5 by 1, 5 by 2, 5 by 3, and so on.
Step-by-step explanation:
5 × 1 = 5
5 × 2 = 10
5 × 3 = 15
5 × 4 = 20
2 × 1 = 2
2 × 2 = 4
2 × 3 = 6
2 × 4 = 8
2 × 5 = 10 and so on
Answer:
A) reflection across the y-axis
Step-by-step explanation:
If 
, then this says that two 
-coordinates are equal for opposite values of 
.
Let 
a point on 
.
Then 
.
We also know that 
and therefore 
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the -axis.
Example if given both and 
, then 
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
Answer:
Brainleist!!!!
Step-by-step explanation:
First calculate the distance between B and D, A and C.
We have the distance between B and D will be: sqrt[(x2-x1)^2+(y2-y1)^2] = 8.5
The distance between A and C will be: 14.14
We have the area of rhombus: 1/2 * 8.5 * 14.14 = 60 square units.
Answer:
50% value change.
Step-by-step explanation:
A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.
Therefore, $15 is a 50% percent change from $10.
Answer:
−x^2−11
Step-by-step explanation:
Distribute the Negative Sign:
=−3x−4+−1(x^2−3x+7)
=−3x+−4+−1x^2+−1(−3x)+(−1)(7)
=−3x+−4+−x^2+3x+−7
Combine Like Terms:
=−3x+−4+−x^2+3x+−7
=(−x^2)+(−3x+3x)+(−4+−7)
=−x^2+−11
