Answer:
<em>The sale price of the washing machine is £207.50.</em>
Step-by-step explanation:
<u>Percentages
</u>
To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.
Suppose the normal price of the washing machine was x before the discount. The discount is:
17% of x = 17/100 * x = 0.17x
This discount is given as £42.50, thus:
0.17x = £42.50
Solving:
x = £42.50/0.17
x = £250
The sale price is:
£250 - £42.50 = £207.50
The sale price of the washing machine is £207.50.
X+ 77.5 because if you subtract 25 from 180 you get 155. Then divide 155 by 2 and you get 77.5
The function is y=f(x)=-2x-3
the graph of this function are all pairs (x, y)=(x, f(x))=(x, -2x-3)
the y-intercept of a graph of a function, is the point where the graph cuts the y-axis, which happens at x=0.
at x=0, f(x)=f(0)=-2*0-3=-3
the x-intercept(s) of the graph, are the point(s) where the graph intersects the x-axis. At those points, the y-coordinate is 0.
so the x-intercept(s) are points of the form (x, 0)
now,
(x, 0)=(x, -2x-3)
0=-2x-3
2x=-3
x=-3/2
Answer:
x-intercept: (-3/2, 0)
y-intercept: (0, )
Answer:
2/5
Step-by-step explanation:
Multiply all the fraction
The first answer is 2
The Second is 8
The third is, if the w changes then the p would change as well resulting to multiplication
Hope this helps!!!
