Find missing Heights

Answer:

Domain: (-7, 4]

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, the line's x-values span from -7 to 4. Since -7 is an open dot, it is exclusive in the domain. Since 4 is a closed dot, it is inclusive in the domain:

(-7, 4] or -7 < x ≤ 4

Answer:

C)  6 inches

Step-by-step explanation:

(√72)² = x² + x²

72 = 2x²

72/2 = x²

36 = x²

√36 = √x²

6 = x

x = 6 inches

Answer:

By Pythagoras theorem, we get

[tex] {x}^{2} + {x}^{2} = {( \sqrt{72}) }^{2} \\ 2 {x}^{2} = 72 \\ {x}^{2} = 36 \\ \boxed{x = 6}[/tex]

Answer:

[tex]g(-3) = 5[/tex]

[tex]f(2) = 13[/tex]

[tex](f + g)(x) = x^2 +2x- 1[/tex]

Step-by-step explanation:

Solving (a):

[tex]g(x) = x^2 - 4[/tex]

Required

Determine g(-3)

[tex]g(x) = x^2 - 4[/tex]

Substitute -3 for x

[tex]g(-3) = (-3)^2 - 4[/tex]

[tex]g(-3) = 9- 4[/tex]

[tex]g(-3) = 5[/tex]

Solving (b):

[tex]f(x) = 3x + 7[/tex]

Required

Determine f(2)

[tex]f(x) = 3x + 7[/tex]

Substitute 2 for x

[tex]f(2) = 3*2 + 7[/tex]

[tex]f(2) = 6 + 7[/tex]

[tex]f(2) = 13[/tex]

Solving (c):

[tex]f(x) = 2x + 3[/tex]

[tex]g(x) = x^2 - 4[/tex]

Required

[tex](f + g)(x)[/tex]

In functions:

[tex](f + g)(x) = f(x) + g(x)[/tex]

So, we have:

[tex](f + g)(x) = 2x + 3 + x^2 - 4[/tex]

Collect Like Terms

[tex](f + g)(x) = x^2 +2x- 4+3[/tex]

[tex](f + g)(x) = x^2 +2x- 1[/tex]

Answer:

D

Step-by-step explanation:

we are given 54x + 4.99x + 7.95

we can simplify like terms

58.99x + 7.95

It is D because in C it says "the actual delivery charge is $58.98" which is not true. It states in the question that it is "$7.95 for delivery", so it has to be D

Answer:

Step-by-step explanation:

5x + y = 9

-10x + 7y = 18

10x + 2y = 18

-10x + 7y = 18

9y = 36

y = 4

5x + 4 = 9

5x = 5

x = 1

(1,4)

answer is D

Step 1:  Find the slope

Every 3 magnets that you buy, you need to pay 1 more dollar.  Therefore, if you have 9 magnets, the cost will be 3 dollars.  Also, if you have 6 magnets, the cost will be 2 dollars.  Finally, if you have 3 magnets, the cost will be 1 dollar.  So... the correct options are Options B, E, F

Step-by-step explanation:

Side length = √Area = √(36x¹⁶y⁴)

= √[(6x⁸y²)²] = 6x⁸y².

Hence the expression for side length is 6x⁸y².

The length of the side of the table top will be 6x⁴y².

Based on the information given, it was stated that the area of the table top was given in the question.

It should be noted that the area of a square is gotten by squaring the sides. Therefore, the length of the side of the square will be 6x⁴y².

Answer:

2,000 miles

Step-by-step explanation:

We are given:

[tex]1 inch=500 miles[/tex]

This can be rewritten as:

[tex]\frac{500 miles}{1inch}[/tex]

This is representative of a unit rate, as we have a [tex]1[/tex] in the denominator. To calculate the number of miles in [tex]4[/tex] inches, simply multiply the unit rate by [tex]4[/tex]:

[tex]\frac{500 miles}{1inch}*4=[/tex]

[tex]\frac{2000 miles}{4 inches}[/tex]

This can rewritten as:

[tex]4inches=2000miles[/tex]

Therefore, there are 2,000 miles in 4 inches.

-

We can check our solution by simplifying the fraction [tex]\frac{2000 miles}{4 inches}[/tex] by dividing both [tex]2000[/tex] and [tex]4[/tex] by [tex]4[/tex] to see if we achieve the unit rate:

[tex]\frac{500 miles}{1 inch}[/tex]

Since this is in fact the unit rate, our solution is correct!

Answer:

[tex]x = \frac{33}{5} [/tex]

or

[tex]x = 6 \frac{3}{5} [/tex]

or

[tex]x = 6.6[/tex]

Step by Step:

Step 1: Rewrite the equation (I used x instead of k.)

[tex] \frac{x}{4} = \frac{33}{20} [/tex]

Step 2: Make x a loner by moving the 4 to the right side.

[tex]4 \times \frac{x}{4} = \frac{33}{20} \times 4 [/tex]

Step 3: Cancel multiplied terms on the left, multiply numbers on the right.

[tex]x = \frac{165}{100} [/tex]

Step 4: Simplify.

Step-by-step explanation:

but tysm for the points

-5+3d+6-4d

anwers is 12/-30

Answer:

Option 2: none of these

Step-by-step explanation:

-x +2y= 4

x-intercept occurs at y=0.

When y=0,

-x +2(0)= 4

-x= 4

x= -4

Thus, x-intercept is (-4,0).

y-intercept occurs at x=0.

When x=0,

0 +2y= 4

2y= 4

y= 4 ÷2

y= 2

Thus, y-intercept is (0,2).

*When writing coordinates, the x and y coordinates are separated by a comma in the bracket. If the 3rd option is a comma instead of a dot (which could instead denote a multiplication sign), it would be the correct option.

The expression that represents the total amount that they'll pay if they tip 20% will be 0.2 + m, because dollars are taxed. so option D is correct.

An equation represents equality of two or more mathematical expression.

When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

It is given that a group of friends ate a meal in a restaurant, and the cost of their bill is m.

We need to find the expression that represents the total amount that they'll pay if they tip 20%.

So we know that,

20% = 0.20

The cost of their bill = m.

The total amount they'll pay including tip = 0.2 + m

Therefore, the expression that represents the total amount that they'll pay if they tip 20% will be 0.2 + m, because dollars are taxed. so option D is correct.
