The number 7.11 would be identified as A “Rational” number.
Answer:
Step-by-step explanation:
A. f(x) = (2x-3)(x-1)
B. since the coefficient of x^2 is positive, the parabola opens upward.
C. plot the vetex, which is between the roots, at x = 5/4, plot the zeroes
plot the points at x=1,2, draw a curve through them.
You can use any of several handy online graphing tools to verify your work.
Step-by-step explanation:
4-(-4x-3) > 36
4 + 4x +3 > 36
4x + 7 > 36
4x > 36-7
4x > 29
x > 29/4
Answer:
D) Square root of 48
Step-by-step explanation:
We have to split the triangle in half and then multiply that by two for the answer. Then we use a²+b²=c² because the two triangles are right triangles, and we know b=4 and c=8, so a²+(4²)=8², or a²+16=64
a² would have to equal 48. a=√48.
