Answer:
Step-by-step explanation:
3y = 12x - 9
y = 4x - 3
y - 1 = 4(x - 2)
y - 1 = 4x - 8
y = 4x - 7
Answer:
See below.
Step-by-step explanation:
Multiplying terms with exponents make the exponents add together.
13.) x² · x⁵ = x⁷
14.) b⁵ · b³ = b⁸
15.) y⁴ · y⁷ = y¹¹
16.) m⁴ · m¹ = m⁵
1. 11x+9=-7
-9 -9
11x=-16
/11 /11
x= -16/11
2. 2x-8-6x=90
2x-6x=-4x
-4x-8=90
+8 +8
-4x=98
/-4 /-4
x=-24.5
3. 5(3x-4)=x+6+12x
15x-20=13x+6
-13x. -13x
2x-20=6
+20. +20
2x=26
/2. /2
x=13
Answer:
See below ↓↓
Step-by-step explanation:
<u>A to B</u>
- Avg. speed = Distance covered / Time taken
- Avg. speed = 200 m / 10 s
- Avg. speed = <u>20 m/s</u>
<u></u>
<u>C to D</u>
- Avg. speed = Distance covered / Time taken
- Avg. speed = (500 - 200) m / (60 - 30) s
- Avg. speed = 300 m / 30 s
- Avg. speed = <u>10 m/s</u>
Part A: D
21,60 x 107% =23,11
Part B: D
23,11 x 115% =26,58
