Answer:

$183 - $105b

Step-by-step explanation:

Let :

Initial fee = a

Constant fee per kilometer = b

Hence, total amount paid can be modeled as :

Total amount = a + bx

Where x = number of kilometers driven

If number of miles driven = 105 km ; and Total amount paid = $183

Total amount = a + bx

$183 = a + 105b

$183 - 105b = a

Hence, Initial amount paid will be :

$183 - $105b

The correct statements are

A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees. The other two angles sum up to 90 degrees. The sides that include the right angle are perpendicular and the base of the triangle. The third side is called the hypotenuse, which is the longest side of all three sides.

From the given figure, we can see that the statement

lines y and z are parallel.

But the statement is not correct, the correct format is ray y and z are parallel to each other.

and, from the second figure the statement is

the distance from point C to AB is 12 cm.

But the statement is incorrect because 12 cm is Hypotenuse distance and the perpendicular distance is 8cm

Answer:

y-coordinate for the SOLUTION to the following system of

equations will be:

The graph is also attached.

Step-by-step explanation:

Given the system of equations

[tex]y\:=\:-x-\:2[/tex]

[tex]y\:=\:4\left(x\:-\:1\right)\:+\:7[/tex]

Let us solve the system of equations to determine the y- coordinate

[tex]\begin{bmatrix}y=-x-2\\ y=4\left(x-1\right)+7\end{bmatrix}[/tex]

[tex]y-4x=3[/tex]

[tex]-[/tex]

[tex]\underline{y+x=-2}[/tex]

[tex]-5x=5[/tex]

so

[tex]\begin{bmatrix}y+x=-2\\ -5x=5\end{bmatrix}[/tex]

solve -5x=5 for x

[tex]-5x=5[/tex]

Divide both sides by -5

[tex]\frac{-5x}{-5}=\frac{5}{-5}[/tex]

[tex]x=-1[/tex]

[tex]\mathrm{For\:}y+x=-2\mathrm{\:plug\:in\:}x=-1[/tex]

[tex]y-1=-2[/tex]

Add 1 to both sides

[tex]y-1+1=-2+1[/tex]

[tex]y=-1[/tex]

Thus, y-coordinate for the SOLUTION to the following system of

equations will be:

The graph is also attached.

Step-by-step explanation:

Step 1: Define

-8x + 1 < 41

Step 2: Solve for x

Here we see that any value x greater than -5 would work as a solution to the inequality.

Answer:

x>-5

Step-by-step explanation:

so first u subtract 1 from both sides

-8x+1-1<41-1

becomes:-8x<40

then u divide  -8 on both sides

-8x/-8  <  40 /-8

x>-5

Answer:

He moved 7 hash marks and the product is $1.60

Step-by-step explanation:

It’s says he starts at 0.2 on the number line, so that’s the second hash mark after the 0. If you move to the right on each hash all the way til the 2, you moved 7 times.

The product of 8 x .20 = 1.60

Zach started on the number line at 0.2 for the cost of one piece of gum he moved  1.4 hash marks and the total cost is 1.6 dollars.

A number line is a horizontal one-dimensional line where we can plot any real number called the real number line. The origin of a real number line is denoted with a value of zero.

Zach bought 8 pieces of bubble gum that were 0.2 dollars each.

If we assume x as the no. of pieces then this can be represented as,

0.2x, where x ∈ N, [1, 8].

Zach started on the no. line at 0.2  for the cost of one piece of bubble gum.

∴ The cost of 8 pieces of bubble gum is (0.2×8) = 1.6 dollars.

So, he moved (1.6 - 0.2) = 1.4 on the number line.

Answer:

B. Andre babysat 5 times this past month and earned the same amount each time. To thank him, the family gave him an extra $4 at the end of the month. Andre earned $99 from babysitting.  and C. A family of 5 drove to a concert. They paid $4 for parking, and all of their tickets were the same price. They paid $99 in total.

Step-by-step explanation: B and C are the right answers

Answer:

5x + 8y ≥ 1200

x + 2y ≤ 500

Step-by-step explanation:

Let x = number of $5 tickets

Let y = number of $8 tickets

Worth of ticket that must be sold = at least $1200

No more than 500 students can fit in the gym

Ticket worth equation :

Cost * number of tickets ≥ 1200

5x + 8y ≥ 1200
