Answer:
A AND D
B AND C
Step-by-step explanation:
If you change A into lowest terms it equals D
and if you cjange B into lowest terms it would equals C
Answer:
![y](https://tex.z-dn.net/?f=y%3C4x-5)
![y\leq 2x+3](https://tex.z-dn.net/?f=y%5Cleq%202x%2B3)
Step-by-step explanation:
step 1
Find the equation of the solid line
From the graph take the points (0,3) and (4,11)
Find the slope
![m=(11-3)/(4-0)\\m=8/4=2](https://tex.z-dn.net/?f=m%3D%2811-3%29%2F%284-0%29%5C%5Cm%3D8%2F4%3D2)
The equation of the solid line in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
we have
![m=2](https://tex.z-dn.net/?f=m%3D2)
----> the y-intercept is the point (0,3)
substitute
![y=2x+3](https://tex.z-dn.net/?f=y%3D2x%2B3)
therefore
The inequality is
![y\leq 2x+3](https://tex.z-dn.net/?f=y%5Cleq%202x%2B3)
step 2
Find the equation of the dashed line
The slope is given
![m=4](https://tex.z-dn.net/?f=m%3D4)
From the graph take the y-intercept (0,-5)
The equation of the solid line in slope intercept form is equal to
we have
![m=4](https://tex.z-dn.net/?f=m%3D4)
substitute
![y=4x-5](https://tex.z-dn.net/?f=y%3D4x-5)
therefore
The inequality is
![y](https://tex.z-dn.net/?f=y%3C4x-5)
because the shaded region is below the dashed line
therefore
The system of inequalities is
![y](https://tex.z-dn.net/?f=y%3C4x-5)
![y\leq 2x+3](https://tex.z-dn.net/?f=y%5Cleq%202x%2B3)
Answer:
i think 64 for your answer
Step-by-step explanation:
Answer:
x = 15°
Step-by-step explanation:
Complementary angles are two angles whose sum = 90°
∠A + ∠B = 90°
3x + 45 = 90
3x = 45
x = 45/3
x = 15°
Answer:
$13,671
Step-by-step explanation:
Each stamp cost $1,953, and the collector bought 7 of them.
1953 * 7 = 13671
The collector spent $13,671 on the stamps.
