Value of x
For an isosceles triangle two sides are equal
AB=BC
7x-3=9x-11.
11-3=9x-7x
8=2x
2x=8
x=8/2
x=4
AB =7x-3=7(4)-3=25 units
BC=9x-11=9(4)-11=25 units
AC=4x+1=4(4)+1=17 units
3^4=81
4*5=20
81+20=101
Hope this helped
The y-intercept can be found when you look where in the graph that the line crosses the y-axis.
If you were given an equation, you would plug in x = 0, to find the y-intercept.
In the graph, you can see that the line crosses at the point (0,-1).
Therefore, the y-intercept is -1.
You would multiply the amount by 1.70 for example increasing £50 by 70% would be £85
