- 16:10
- 24:15
- 40:25
8:5 is just a simplier version of these other ratios
This indicates that 5/2 is less than -1 on the number line.
F(x) = 3x
F(7) = 21
g(x) = -x + 1
g(7) = -7 + 1 = -6
(F x g)(7) = (21) (-6) = -126
So you need to solve for the x and y values...I personally would use a graph. The is this website called desmos, it can help you with this kind of problem. You can see that the green point which is (10, 44) is on the line.. Lets check our work...
y = 4x + 4
44 = 4(10) + 4
44 = 40 + 4
44 = 44
This is your answer. I hope this helps love! :)
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
