First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
Answer:
40 baskets
Step-by-step explanation:
Find out how many baskets she can make in an hour. Since she makes 4 in 1/2 an hour, multiply 4 by 2 to find out how much she makes in an hour. She makes 8 baskets an hour, so multiply 8 by 5. 8 x 5 = 40.
Answer:
The graph of the line in the attached figure
Step-by-step explanation:
we have
This is the equation of a line into point slope form
The slope is 
The line pass through the point (-6,-7)
To graph the line find the y-intercept
Remember that
The y-intercept of the line is the value of y when the value of x is equal to zero
so
For x=0
The y-intercept is the point (0,-3)
with the point (-6,-7) and (0,-3) plot the line
see the attached figure
Answer:
200
Step-by-step explanation:
Divide 400 by 1/2 or 2.
Answer:
1. 136.3/53% = 257.16981...
2. 99/231.2 = 0.4282
3. 853.2/51% = 1672.94117....
4. 439.7/0.56 = 785.17857
5. 496.1/0.92 = 539.23913
6. 0.32 x 238.3 = 76.256
7. 99/376.3 = 0.26308
8. 0.08 x 493.7 = 39.496
Step-by-step explanation:
Good luck
