Answer:
x = 5.4
Step-by-step explanation:
3/x = 4/7.2
cross-multiply:
4x = 21.6
x = 5.4
So you would find out what number in the 9 times tables goes into 25 and there's your answer x
<span>The missing angle measure in triangle ABC is 55°.
The measure of angle BAC in triangle ABC is equal to the measure of angle
EDF in triangle DEF.
The measure of angle ABC in triangle ABC is equal to the measure of </span><span>angle EFD in triangle DEF.
Triangles ABC and DEF are similar by the angle-angle criterion.
True </span>
Answer:
C) The parabola is narrower and reflected across the x-axis.
Step-by-step explanation:
The original parabola has equation:
![f(x) = {x}^{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20)
The transformed parabola has equation
![f(x) = - 1.4 {x}^{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20-%201.4%20%7Bx%7D%5E%7B2%7D%20)
How wide the graph is can be determined by the absolute value of the coefficient.
The smaller the absolute value of the coefficient, the wider the graph.
Since
![|1| \: < \: | - 1.4|](https://tex.z-dn.net/?f=%20%7C1%7C%20%20%5C%3A%20%20%3C%20%20%5C%3A%20%20%7C%20-%201.4%7C%20)
The original graph is wider than the transformed graph.
Also the negative factor tells us there is a reflection in the x-axis.
