Answer:
x = 17
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + x^2 = (sqrt(514))^2
225 + x^2 = 514
Subtract 225 from each side
225-225 + x^2 = 514-225
x^2 =289
Take the square root of each side
sqrt(x^2) = sqrt(289)
x = 17
3. 560%
4. 1/200
5. 360%
6. 42, 35% of 120 is 42.
7. 79.38, approximately 79
8. 79.38, approximately 79
Answer:
Step-by-step explanation:
ok slope is m because there is a thing called y-intercept, so you use x to find slope.
the whole formula is y = mx +b
in this case m = slope with x being the part of the slope from where you got it from
the answer would be m =
x
i hope this helped :)
Answer:
x=3/radical2,-3/radical2,3/4
Step-by-step explanation:
By factoring you get
4x(2x^2-9)-3(2x^2-9)=(2x^2-9)(4x-3)=0
x^2=9/2, x=3/4
x=3radical2/2, -3radical2/2 , 3/4
