Answer:
34
Step-by-step explanation:
5(14-2^3) + 8 / 2
= 5(14 - 8) + 4
= 70 - 40 + 4
= 30 + 4
= 34

I = PRT/100
3240 = 18 000 * R * 6 /100
3240 = 180*R*6
3240 / (180*6) = R
3 = R
so the rate will be 3%.
Answer: y=2x-1
We know that the equation of a line is y = mx + b, where m is the gradient and b is the y-intercept.
First to find the gradient, we use the formula y2-y1/x2-x1.
x1 and y1 being the first set of coordinates (2,3) and x2 and y2 being the second set (4,7)
Now we sub in:
m=7-3/4-2
m=4/2
m=2
This is our gradient and we can put it into the equation: y=2x+b
Now we find the y-intercept (b). Since the y-intercept isn’t shown, we can sub in the coordinates to find it.
y=2x+b
Sub (2,3)
3=2(2)+b
3=4+b
-1=b
Sub (4,7)
7=2(4)+b
7=8+b
-1=b
Subbing in both coordinates gives us -1 as the y-intercept, so the finished equation is: y=2x-1
