First, simplify the 16:4 ratio.
• 16:4 ÷ 2 = 8:2 ÷ 2 = 4:1
Now, check to see if they're equivalent:
• 3:1 = 4:1 ???
- 3:1 =/= 4:1
So, NO these ratios are not equivalent.
<span>To write in standard notation means writing the equation "normally", solving it and then writing the resulting number in its extensive form with all explicit digits. 10^-4 is 0,0001, so: 8,75x0,0001=0,000875</span>
F(-3)
f(a) = -2a² - 5a + 4
Substitute a with its value, -3
f(-3) = -2(-3²) - 5(-3) + 4
f(-3) = -2(9) + 15 + 4
f(-3) = -18 + 19
f(-3) = 1
the value of f(-3) is 1.
Answer:
AAS
Step-by-step explanation:
It has two sets of angles that are congruent. I'm no 100% so hope the picture helps you a little!!
By factoring, x equals both -5 and 7.
