Answer:

x = 5

The two consecutive odd integers are: 5, 7

And...checking

sum = 12

Step-by-step explanation:

Answer:

12 + 1.79(x) ≤ 50

Number of drill bits = 21

Step-by-step explanation:

Given:

Total amount = $50

Amount of book = $12

Price of each bit = $1.79

Find:

Number of drill bits

Computation:

Assume, Number of drill bits = x

So,

12 + 1.79(x) ≤ 50

1.79(x) ≤ 38

x ≤ 21.220

Number of drill bits = 21

Step-by-step explanation:

[tex]f(2) = \frac{1}{2} \times 2 = 1\\f^{-1}(1) = 2 \times 1 = 2\\f^{-1}(f(2)) = f^{-1}(1) = 2[/tex]

Note: [tex]f^{-1}(f(x)) = x[/tex] because f -1 and f cancel each other out.

Answer:

f(2) =  

⇒ 1

f−1(1) =  

⇒ 2

f−1(f(2)) =  

⇒ 2

f−1(−2) =  

⇒ -4

f(−4) =  

⇒ -2

f(f−1(−2)) =

Answer:

A. The equation representing the bicyclist with equal speed, v, meeting after x hours is 75 - v·x = 45 + v·x

B. The bicyclist meet after 1.5 hours

C. They were 60 miles from the parking lot when they meet

Step-by-step explanation:

A. The starting location of the one of the bicyclist = 75-mile marker

The starting location of the other bicyclist = 45-mile marker

The direction of motion of the bicyclist = Towards each other

The time after which the bicyclist meet = x hours

The expression for the distance from the parking lot are

75 - 10x and 45 + 10x

Whereby the bicyclist are have the same speed, v, we have;

The location where they meet is 75 - v×x = 45 + v×x

B. Solving for x, we have;

75 - v×x = 45 + v×x

75 - 45 = v×x + v×x = 2×v×x

30 = 2×v×x

x = 30/(2×v)

Taking the speed of the bicyclist as 10 mph from the equation of their distance from the parking lot, by dimensional analysis, we have;

x = 30/(2×v) = 30/(2×10) = 1.5

x = 1.5 hours

The bicyclist meet after 1.5 hours

C. Their distance from the packing lot is given by substituting the time, x, it took them to meet into the expression for the distance from the parking lot as follows;

75 - 10 × 1.5 = 60 miles

45 + 10 × 1.5 = 60 miles

Therefore, they were 60 miles from the parking lot when they meet.

Answer:

A. The equation representing the bicyclist with equal speed, v, meeting after x hours is 75 - v·x = 45 + v·x

B. The bicyclist meet after 1.5 hours

C. They were 60 miles from the parking lot when they meet

Step-by-step explanation:

A. The starting location of the one of the bicyclist = 75-mile marker

The starting location of the other bicyclist = 45-mile marker

The direction of motion of the bicyclist = Towards each other

The time after which the bicyclist meet = x hours

The expression for the distance from the parking lot are

75 - 10x and 45 + 10x

Whereby the bicyclist are have the same speed, v, we have;

The location where they meet is 75 - v×x = 45 + v×x

B. Solving for x, we have;

75 - v×x = 45 + v×x

75 - 45 = v×x + v×x = 2×v×x

30 = 2×v×x

x = 30/(2×v)

Taking the speed of the bicyclist as 10 mph from the equation of their distance from the parking lot, by dimensional analysis, we have;

x = 30/(2×v) = 30/(2×10) = 1.5

x = 1.5 hours

The bicyclist meet after 1.5 hours

C. Their distance from the packing lot is given by substituting the time, x, it took them to meet into the expression for the distance from the parking lot as follows;

75 - 10 × 1.5 = 60 miles

45 + 10 × 1.5 = 60 miles

Therefore, they were 60 miles from the parking lot when they meet.

Answer:

The correct options are;

D. Triangles ABC and A'B'C' are congruent

E. Angle ABC is congruent to angle A'B'C'

F. Segment BC is congruent to segment B'C'

H. Segment AQ is congruent to segment A'Q'

Step-by-step explanation:

The given information are;

The angle of rotation of triangle ABC = 60°

Therefore, given that a rotation of a geometric figure about a point on the coordinate plane is a form of rigid transformation, we have;

1) The length of the sides of the figure of the preimage and the image are congruent

Therefore;

BC ≅ B'C'

2) The angles formed by the sides of the preimage are congruent to the angles formed by the corresponding sides of the image

Therefore;

∠ABC ≅ ∠A'B'C'

3) The distances of the points on the figure of the preimage from the coordinates of the point of rotation are equal to the distances of the points on the figure of the image from the coordinates of the point of rotation

Therefore;

Segment AQ ≅ A'Q'.

Complete question :

The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legionaries and 3archers. It only costs 3 denarius per day to support one legionary and one archer. Use a system of linear equations in two variables. Can we solve for a unique cost for each soldier?

Answer:

No unique solution

Step-by-step explanation:

Given that:

Cost of supporting 3 legion aries and 3 archers = 10 denarius daily

Cost of supporting one legionary and one archer = 3 denarius

Let:

Legionaries = l ; archers = a

Equation for the first sentence :

3l + 3a = 10 - - - (1)

Second sentence :

l + a = 3 - - - - - (2)

From (2)

l = 3 - a

Substituting l = 3 - a into (1)

3(3 - a) + 3a = 10

9 - 3a + 3a = 10

9 - 0 = 10

The variable cancels out, Hence, ( there is no unique solution to find the cost of each soldier)

Answer:

No; the system has no solution.

Step-by-step explanation:

We'll use L to represent the cost per day of a legionary, and we'll use A to represent the cost per day of an archer. So we have the following system of equations:

3L+3A=10

L+A=3

If we multiply both sides of the second equation by 3, we get the equation 3L+3A=9

But this indicates that the cost to support 3 legionaries and 3 archers is 9 denarius. The first equation indicates that it costs 10 denarius to support 3 legionaries and 3 archers.

The cost cannot be 9 denarius and 10 denarius at the same time.

Henceforth the answer is:

No; the system has no solution.

Answer:

n-2

Step-by-step explanation:

1. Find what has been done to the input value to give the output value. Here, we can see that each input value is two more than each output value, so two has been subtracted from each input value to give the output. This means that the rule for this function is: take the input value and subtract two.

2. Express this in terms of n. We can then express this in terms of n (using n to show the rule that we have found). Since n is the input value we have, to find the output when the input is n, we subtract two from n. This gives us our answer of n-2.

Answer:

x = -3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

To find the value of x, you need to get rid of parentheses! So, 4*x=4x. 6*4=24. Now we have, -2x+6=4x+24. Then we want to get all the x on one side, and the other numbers on the other side. We can add -2x to make it 0, but to make it equal, you need to add it to the other side. So, 4x+2x=6x. You can subtract 24 too! After we do all that, we get: -18=6x. To get x, we need to divide by 6. 6x/6=x. -18/6=-3.
