Answer:
x=40
Step-by-step explanation:
Both angles are equal. So the equation needs to equal 156.
Just plug in points for x until the answer is 156.
In this case, when we plug in 40, it works!
Answer:
1. 5lb bag is cheaper
2. 6 mpm (minutes per miles)
3. Brycen
4. 18 mpm faster
5. 32 total shapes
6. 75
7. not enough info
8. 50 miles
9. 2
10. 2
Step-by-step explanation:
3lb=$3.54=1lb=$1.18
5lb=$5.85=1lb=$0.85
12 minutes/2 miles=6 mpm
24 minutes/1 mile=24 mpm
24-6=18 mpm faster
25% of 100= 4
4×8=32
60% of 80= 75
process of elimination:
24.5 is less than 35 so no
50×.7=35, total miles is 50
We write the equation in the form of directional.
y -1 = 6x ⇔ y = 6x + 1
y - 1 = 3x ⇔ y = 3x + 1
y - 7 = 2x - 6 ⇔ y = 2x - 6 + 7
y = 2x + 1
y - 7 = x - 2 ⇔ y = x - 2 + 7
y = x + 5
Equations cleverly arranged .
Point Q = (0,1)
b factor , not only fits the last equation
In the drawing have engraved points Q and R are tangent linear function appropriate to that point . This graphics solution . y = 3x + 1
Answer b
We check choice by the system of equations , where substitute wartoćsi points Q and R to the model equations linear function
The result of equations confirmed our choice Answer b
