Answer:
26 cm
Step-by-step explanation:
we can make an equation to find the lengths
2(x+7x-2) = 60
x : length of width
7x-2 : the length of length
2 : the two pairs of length and width
solving this equation, we get x = 4
but that is not the answer
we have to plug in x=4 into 7x-2
7*4-2 = 28-2 = 26
Answer:
9
Step-by-step explanation:
The left circle is the input and the right circle is the output. Looking at 9 in the left circle, it leads to 9 in the right circle, so 9 is the answer.
This would also mean f(-8)=-5 and f(-6)=1
Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)
The answer is y=-2x+3 because the slope is -2 which solves the first half and then 3 is the y intercept so y=-2x+3
Answer:
x=5
Step-by-step explanation:
22 + 4x - 32 < 0
+32 +32
22 + 4x < 32
-22 -22
2x < 10
divide by 2
x=5
