Answer:
7
Step-by-step explanation:
20 - 12 = 8
15 - b = 8
-b = 8 - 15
b = 7 ( -ve signs will become +ve)
Answer:
1a. 8
1b. AB & BC
1c. AC
2.
miles
3. NO
Step-by-step explanation:
1a. AC is your hypotenuse which is C² and BC is B², so we plug it in the equation.
A²+6²=10²
A²+36=100
A²=64
A=
A=8
1b. Legs are the two shorter sides, AB & BC, which are 6 & 8 respectively.
1c. The hypotenuse is the longest side AC
2. Make lines that make the graph for a triangle with a line. My graph is linked below. Then counts the points, AC=6, BC=4, then use the pythagorean therom.
6²+4²=X²
36+16=52
=X
3. 15²+17²=19²
514=361
not possible
so it is not a right triangle
Answer:
daffodil = $13 Tulip = $7
Step-by-step explanation:
6t + 12d = 198
7t + 6d = 127
6t = 198 - 12d
t = 33 -2d
substitute
7(33-2d) + 6d = 127
231 -14d +6d = 127
- 8d = -104
d =13
6t + 12(13) = 198
6t +156 = 198
6t = 42
t = 7

Answer:
y= -3+7x
Step-by-step explanation:
7x-y=3 for y
Move variable to the right
-y+3-7x
Change the signs
y= -3+7x
