Answer:26°
Step-by-step explanation:
Answer:
D. Down 5, Left 2
Step-by-step explanation:
-5 on the outside means it will go down 5.
+2 directly grouped with the variable means it will do the opposite, so it goes left 2.
Answer:
3. BDE is congruent to BAC; corresponding angles postulate
4. B is congruent to B; reflexive property of equality
Step-by-step explanation:
I took the test.
Answer:
<h2>m = 21, b = 5 → y = 21x + 5</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
=====================================
From the table we have y-intercept (0, 5) → <em>b = 5 </em>and other point (1, 26).
Calculate the slope:
![m=\dfrac{26-5}{1-0}=\dfrac{21}{1}=21](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B26-5%7D%7B1-0%7D%3D%5Cdfrac%7B21%7D%7B1%7D%3D21)
