Answer:

-11≤x

Step-by-step explanation:

Given

6.7 ≥ -0.2x +4.5----------------collect like terms

6.7-4.5 ≥ -0.2x--------------divide by -0.2 both sides

2.2/-0.2 ≥ -0.2/-0.2x-------------------reverse the sign

-11 ≤ x

For this case we have the following inequality:

6.7\geq 0.2x + 4.5

Subtracting 4.5 from both sides of the inequality:

6.7-4.5\geq -0.2x\\2.2\geq -0.2x

Dividing between 0.2 on both sides:

\frac {2.2} {0.2} \geq-x\\11 \geq-x

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

-11 \leq x

ANswer:

x \geq-11

Suppose that y varies directly with x. Given x=4 when y=20.<br> Find y when x = 3
scoray [572]

Answer:

y = 15

Step-by-step explanation:

Given: y varies directly with x, x=4 when y=20

To find:  y when x = 3

Solution:

As y varies directly as x, it means that as x increases, y also increases by the same factor.

As y varies directly with x,

y=kx

Here, k is a constant

As x = 4 when y = 20,

20=4k\\k=\frac{20}{4}=5\\\Rightarrow y=5x

Put x = 3

y= 5(3) = 15

The graph shows the number of jam jars filled by two different machines over several minutes.
IgorC [24]
The correct answer is y = 1.5x, A.
I am sure it is because I took the K12 test. I used the answer from the other person that answered this, and got it wrong. I reviewed the test, and It says that 1.5x is correct.

For a sequence defined by f(1)=13 and 2f(n-1)+(n-2), which of the following is the value of f(4)
densk [106]
Given that:
f(1)=13 and 2f(n-1)+(n-2)
then:
f(4) will be found as follows:
f(2)=2f(2-1)=2f(1)=2*13=26
f(3)=2f(3-1)+(3-2)=2f(2)+1=2*26+1=53
f(4)=2f(4-1)+(4-2)=2f(3)+(4-2)=2(53)+2=108

Thus:
Answer:(3) 108
