four times a number x is at least -12
an inequality is ?
the solution is ?

Answer:

the first person is wrong

Step-by-step explanation:

the answer is -1/10x+240

The function can be used to find y, the number of gallons of fuel remaining in the tank of the semi-truck after it has traveled x miles is -1/10x + 240.

The equation of a straight line can be represented by:

y = mx + c

Where m is the slope of the graph and c is the intercept on the y axis.

From the graph attached, the intercept on the y axis is 240,

therefore c = 240.

To find the slope, we use the equation:

m = change in y / change in x

m = (195 - 240) / (450 - 0)

m = -45/450

m = -1/10

by substituting the value of c and m in the equation gives:

y = mx + c

Therefore, the answer is -1/10x + 240.

Answer: I don't know the answers for 3&4

Step-by-step explanation:

Question 1:

1foot=0.3m(2.718282)t(2.718282)r

Step 1: Divide both sides by o^2t.

fo2to2t=2.216717mrto2t

f=2.216717mro2

Answer:

f=2.216717mro2

Question 2:

1mil(2.718282)=1.6kilom(2.718282)t(2.718282)rs

Step 1: Add -11.82249iklmorst to both sides.

2.718282ilm+−11.82249iklmorst=11.82249iklmorst+−11.82249iklmorst

−11.82249iklmorst+2.718282ilm=0iklmorst

Step 2: Factor out variable i.

i(−11.82249klmorst+2.718282lm)=0iklmorst

Step 3: Divide both sides by -11.82249klmorst+2.718282lm.

i(−11.82249klmorst+2.718282lm)−11.82249klmorst+2.718282lm=0iklmorst−11.82249klmorst+2.718282l

Answer:

i=0ikorst−11.82249korst+2.718282

Answer:

62 weeks

Step-by-step explanation:

What we need is to represent the ratios in expression

For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is

992-5x

x is the weeks

And the other case the expressions is

1240-9x

The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount

992-5x=y

1240-9x=y

in both the y is the same, then

992-5x=1240-9x

992-1240=-9x+5x

-248=-4x

-248/-4=x

62=X

and that is the weeks we need for the amount being the same in both tanks

Answer:

First answer = 36

Second answer = 9

Third answer =1/4

Step-by-step explanation:

The probability of rolling an even number and then an odd number is 1/4.

Probability is simply the chance of getting an event from a sample space. Total probability of all the outcomes in an experiment will be always 1.

Probability of an event can be found by dividing the number of desired outcomes with the total number of outcomes.

Here two number cubes are rolled. Each number cube has total 6 outcomes.

If the sample space consists of all the outcomes of first and second number cubes,

Size of sample space = 6² = 36

We have to find the probability of rolling an even number on the first cube and then an odd number on the second cube.

There are 3 chances of having an even number for the first cube which are 2, 4 and 6.

There are 3 chances of having an odd number for the second cube which are 1, 3 and 5.

Therefore number of desired outcomes = 3² = 9

Probability (first is even and second is odd) = Number of desired outcomes / Size of the sample space

Probability (first is even and second is odd) = 9/36 = 1/4

Hence the probability of getting an even number on the first number cube and then an odd number on the second cube is 1/4.

Answer:

The farmer's market apples cost $1.50 per pound.

The grocery store apples cost $1.35 per pound.

Samantha should buy her apples from the grocery store, where the apples cost $0.15 less per pound than the farmer's market apples.

Step-by-step explanation:

The graph shows that 2 pounds of apples costs $3.00, so divide the cost by 2 for the cost of a single pound:

3 ÷ 2 = 1.5

Solve for the grocery store apple cost per pound by replacing x with 1 in the given equation:

y = 1.35(1)

Then solve for y:

y = 1.35
