4x+1+57=90
4x+58=90
4x=32
X=8
Answer:
2
Step-by-step explanation:
5(2)+2=12
(2)+4=6
5x+2 is twice the length of x+4. Therefore the answer is 2
Answer:
5^-2
Step-by-step explanation:
All you have to do in this situation is subtract the powers :)
10-12=-2
The equation would be y = -3/2x + 1/2
Answer:
The y-intercept is (0,0), obtained by setting x = 0 in the given function.
The x-intercepts are (0,0) and (0.4/0.008, 0), or (0,0) and (0,50).
Step-by-step explanation:
It's best to label a quantity like this one: y = x(0.4 - 0.008x). Perform the indicated multiplication so as to obtain a quadratic equation of the form y = ax^2 + bx + c: 0.4x - 0.008x^2; here, that works out to y = -0.008x^2 + 0.4x + 0. The y-intercept is (0,0), the value of the function when x = 0.
The x-intercepts are found by setting y=0 and solving for x: (0,0) and (50,0)
