Just in case you didn’t know, you can also use photomath, for math problems. They give you the answer and they also include the steps. You can do that instead of waiting for someone to answer here, it’ll be alot faster:)
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
If you would like to find the x-intercepts of the function f(x) = - 2 * x^2 - 3 * x + 20, you can calculate this using the following steps:
f(x) = - <span>2 * x^2 - 3 * x + 20
</span>f(x) = - (2x - 5) * (x + 4)
1. x = - 4
2. x = 5/2
(x, y) = (-4, 0)
The correct result would be (-4, 0).
Answer: Dilation and stretch
Step-by-step explanation:
- Rigid transformations that are also called as isometry are the transformations which preserves the side lengths and the angle measures of a polygon. It does not affect the size of the shape. The shape doesn't shrink or get enlarger.
There are four rigid transformations: <em>reflections, rotations, translations and glide reflection.</em>
- Dilation and stretch are non rigid transformation because they change the size of the figure. They produces similar figures.
