Answer:
30
Step-by-step explanation:
Exterior angle equals sum of opposite interior angles
3x = 2x + 30
3x - 2x = 30
x = 30
Answer:
4. y+3=-1/3(x-9) 6a. 15x-y=0 6b. $150
Step-by-step explanation:
4.
Point slope form formula: y-y1=m(x-x1)
Includes origin and point (9,-3)
m= y2-y1/x2-x1
-3-0/9-0= -3/9=-1/3
slope= -1/3
Since we already have the point (9,-3),
enter the information above into the point slope form formula.
y-(-3)=-1/3(x-9)
<u>y+3=-1/3(x-9)</u>
6.
3h--> $75
1h--> $15
a)
Standard form: Ax + By = C
m(slope)=15
y=15x
y-15x=0
-15x+y=0
<u>15x-y=0</u>
b)
<u>10 hours of work---> $150</u>
Answer:
x column- 1.25, 7.5, 45.
y column- 5, 30, 180.
Step-by-step explanation:
Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.
