decreasing by 1.6
Answer: PTR = 80°
PTQ= 45° PTS= 128°?
Step-by-step explanation:
See angles <ptr <ptq <pts ar based off of the number of degrees on the protractor
Answer:

y=7
Step-by-step explanation:
to find y itercept =0
to find x intercept=0
Answer:
Her actual distance for the trip will be 112.5 miles.
Step-by-step explanation:
You need to analize the information provided in the exercise.
You know that the scale of the map Kelsey is reading is:
![2\ inches=50\ miles](https://tex.z-dn.net/?f=2%5C%20inches%3D50%5C%20miles)
And according to the exercise, Kelsey's trip measures 4.5 inches on that map.
Therefore, in order to calculate what will be her actual distance for the trip (Let be
this distance), you can set up the following proportion:
![\frac{50\ miles}{2\ inches}=\frac{x}{4.5\ inches}](https://tex.z-dn.net/?f=%5Cfrac%7B50%5C%20miles%7D%7B2%5C%20inches%7D%3D%5Cfrac%7Bx%7D%7B4.5%5C%20inches%7D)
Finally, you must solve for
. Then, you get:
![\frac{(50\ miles)(4.5\ inches)}{2\ inches}=x\\\\x=112.5\ miles](https://tex.z-dn.net/?f=%5Cfrac%7B%2850%5C%20miles%29%284.5%5C%20inches%29%7D%7B2%5C%20inches%7D%3Dx%5C%5C%5C%5Cx%3D112.5%5C%20miles)
Therefore, her actual distance for the trip will be 112.5 miles
1. It's useful to divide out the GCF first because it makes factoring easier because the coefficients are smaller requiring less steps. 2. First, identify a,b, and c in the trinomial ax^2+bx+c. Then, write down all factor pairs of c Then, identify which factor pair from the previous step sums up to b. Then, Substitute factor pairs into two binomials 3. Key features are the y-intercept the zeros and the end behavior. to graph these put a pont on the intercepts and draw a line through them that matches the end behavior. 4. A binomial that is the difference of perfect squares is in the form of a^2-b^2 And its factor form is a^2 - b^2=(a-b)(a+b)5. Factoring by grouping often works well with four-term polynomials but the last step of factoring the common binomial only works when both terms contain the exact same binomial.
