Answer:
see explanation
Step-by-step explanation:
f(x) is valid for all real values of x , so
domain is x ∈ R
Since the coefficient of the x² term < 0 , then
f(x) has a maximum vertex at (0, 5 )
range is ( - ∞ , 5 ]
AAS they have a congruent side marked, the vertical angle and the marked congruent angle
Answer:
28% decrease
Step-by-step explanation:
If we decrease by 60%, we are keeping 100-60 = 40%
Let x be the original amount
decrease by 60% = keep 40%
.40 x
If we increase by 80%, we are keeping 100+80 = 180%
(.40x) * 180%
.40x * 1.80
.72x
Take .72 times the original amount
100 - .72 = 28
It decreased 28 %
Answer:
4/5
Step-by-step explanation:
Find 2 defined points like (-2,0)(3,4) in other to reach the point (3,4) from (-2,0) it moves 5 times front and 4 times up
Up is Y value
Front is X value
To solve it is adding the value that you get from moving it in this case
5 front X equals to 5
4 up Y equals to 4
Then is 4/5
because the formula is Y/X
