Answer:
E
Step-by-step explanation:
28=28
14*2=28
4*28
they are both equal
See the attached figure.
<span>f(x)=-2x−3 ⇒⇒ black graph ⇒⇒ range = R
</span>
<span>g(x)=-2|x+3|−3 ⇒⇒ red graph ⇒⇒ range = </span><span>{y∣y ≤ -3}
</span>
<span>h(x)=-2(x−4)²+3 ⇒⇒ blue graph ⇒⇒ </span><span>range = {y∣y ≤ 3}
</span>
<span>j(x)=-2x³+3x²+x−1
⇒⇒ green graph </span>⇒⇒ range = R
∴ <span>
The function which has a range of {y∣y ≤ 3} is </span><span>
h(x)=-2(x−4)²+3

12. 37%
Answer:
u=2
Step-by-step explanation:
8u-21 = 2u-9
+21 +21
8u= 2u + 12
-2u -2u
6u= 12
divide by 6, u=2 !!
2/13 * 26 2/5
2/13 * 132/5
2 * 132= 264
13 * 5= 65
264/65 = 4 4/65
