Answer:
b=24
Step-by-step explanation:
you use a^2+b^2=c^2
so 10^2+b^2=26^2
100+b^2=676
subtract 100 from both sides
b^2=576
then sq rt the 576 to get 24
Answer:
x-intercepts: -5 +/-
. y-intercept: 4
Step-by-step explanation:
For x-intercepts use the quadratic equation
![x= (-b +/-\sqrt{b^2-4ac} )/2a](https://tex.z-dn.net/?f=x%3D%20%28-b%20%2B%2F-%5Csqrt%7Bb%5E2-4ac%7D%20%29%2F2a)
Fill in your values:
![x= (-10 +/-\sqrt{100-16} )/2](https://tex.z-dn.net/?f=x%3D%20%28-10%20%2B%2F-%5Csqrt%7B100-16%7D%20%29%2F2)
And solve
![x=-5 +/- \sqrt{21}](https://tex.z-dn.net/?f=x%3D-5%20%2B%2F-%20%5Csqrt%7B21%7D)
For y-intercepts set x=0 and solve. In this case, setting x= 0 gives you y=4.
Answer:
Step-by-step explanation:
Let 'x' be the original price.
x + 39% of x = 197.38
x + 0.39 x = 197.38
1.39x = 197.38
x = 197.38/ 1.39
x = 142
