What is the question and answer options?
Step-by-step explanation:
b. f(x) is an exponential function =>
with the formula :
f(x) = 4^x , x ≥ -2
g(x) is a linear function =>
with the formula :
g(x) = x + 4 , x ≥ -1
c. f(x) will increase as geometric sequence
g(x) will increase as arithmetic sequence
d. f(x) = g(x)
4^x = x+4
x = 1.1875 (estimated)
Answer:
2,840
Step-by-step explanation:
since the three is in the tens place and 7 in single <em>if 5 and up round up fi 4 and below leave it alone you</em> will then take the 3 and round up to give you 2,840
Answer:
-1 > -3
Step-by-step explanation:
In the first play, Mark's favorite team lost 3 yards. This mean a negative representation as is a lost: -3.
In the second play, Mark's favorite team lost 1 yards. This mean a negative representation as is a lost: -1.
When locating -3 and -1 in the number line, all the numbers to the right of the number -3 are greater than this number.
From this we can say that the inequality statement is: -1 > -3.
This means that -1 is greater than -3.
Answer:
2. x = 3
3. x = 10 and y =2
Step-by-step explanation:
2.
From inspection, we can see that EF = 10 and KL = 5
Therefore the ratio KL : EF = 5 : 10 = 5/10 = 1/2
This means that the side measures of ΔJKL are 1/2 the corresponding side measures of ΔGEF
Therefore, if GF = 22, then JL = 22 ÷ 2 = 11
So: 2x + 5 = 11
⇒ 2x = 11 - 5 = 6
⇒ x = 6 ÷ 2 = 3
x = 3
3.
From inspection, we can see that DF = 12 and HJ = 9
Therefore the ratio DF : HJ = 12 : 9 = 12/9 = 4/3
This means that the side measures of ΔDEF are 4/3 times the corresponding side measures of ΔHGJ
Therefore, if HG = 6, then DE = 6 x 4/3 = 8
So: 2y + 4 = 8
⇒ 2y = 8 - 4 = 4
⇒ y = 4 ÷ 2 = 2
y = 2
Similarly, if GJ = 24, then EF = 24 x 4/3 = 32
So: 4x - 8 = 32
⇒ 4x = 32 + 8 = 40
⇒ x = 40 ÷ 4 = 10
x = 10
