d) ???

Answer:

The value of x is 7.

Step-by-step explanation:

Both RT and SQ are diagonals of the rectangle, so they have the same measure.

We have that:

[tex]RT = 4x - 16, SQ = x + 5[/tex]

Since they are equal:

[tex]4x - 16 = x + 5[/tex]

[tex]4x - x = 5 + 16[/tex]

[tex]3x = 21[/tex]

[tex]x = \frac{21}{3}[/tex]

[tex]x = 7[/tex]

The value of x is 7.

Answer:

The unknown measure is 12.

Answer:

10

Step-by-step explanation:

First you add 6 to get to 0 on the number line. Then you add 4 to get to your final destination which is 4. You add them together to get 10.

Answer:

Positive

Step-by-step explanation:

There are a couple ways we can go about this.

First, we can see that as x increases, so does y, so that means its positive

For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place

If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.

We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.

Answer:

y - 18 = -1.5(x - 12)

Step-by-step explanation:

A = (12, 18)

B=(1.25(12), 0.75(18)) = (15, 13.5)

Find slope:  m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5

Point slope form:  y - y1 = m(x - x1)

Using point A as (x1, y1)

y - 18 = -1.5(x - 12)

Answer:

it would be A because if you repeat an x value it can cause it to be a a non-function

Answer: 3 7/14 + 2 12/14 = 5 19/14

Step-by-step explanation:

Find the LCM of the denominator.

2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

7 = 7, 14, 21, 28, 35

3 1/2 = 3 7/14

2 6/7 = 2 12/14

3 7/14 + 2 12/14 = 5 19/14

Answer:

1/10

Step-by-step explanation:

To convert a ratio to a fraction, you divide the number on the left by the number on the right. This gets you (3/5)/6. When dividing fractions by whole numbers, you need to convert the whole number to a fraction. I converted 6 to 6/1, so that gave me (3/5)/(6/1). You then multiply the top number by the bottom number to get the numerator of the answer, and the middle 2 numbers multiplied is the denominator. The answer is (3x1)/(5x6), or 3/30, which can be simplified to 1/10.

Answer:

The answer is -4.

Step-by-step explanation:

It is -4 using the method of PEMDAS.  Subtract 4 and 2 together in the parentheses to get 2.  Multiply to the third root power to get 8.  Then, multiply -3 by 4 together to get -12.  Finally, subtract 12 from 8 to get -4 as your final answer.

Mixed number Fraction:

A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

(Here),

Nori had  [tex]2\frac{1}{12}[/tex] bags of apples.

Given, he used  [tex]1\frac{5}{12}[/tex] bags of apples.

Nori left =   [tex]2\frac{1}{12}[/tex]  -   [tex]1\frac{5}{12}[/tex]

=> (25 / 12) - (17 / 12)

=> 8 / 12 => (2 / 3)

Step-by-step explanation:

Answer: The rate is increasing upwards, if that is what you were asking?

Step-by-step explanation: Let me know if you need anything else, please :)

The rate of change for payment option 1 is 1 and for payment option 2 is 0.25.

At 4th visit the cost of both the plans will be same.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.

We know the slope m = (y₂ - y₁)/(x₂ - x₁).

Payment option 1 has two points (0, 2) and (2, 4).

Slope(m₁) = (4 - 2)/(2 - 0).

Slope(m₁) = 2/2

Slope(m₁) = 1.

4 = 2(1) + b.

b = 2.

y = x + 2.

Payment option 2 has,

$0.25 every visit is $(1/4) and it is the rate of change or the slope.

y = 0.25x + 5.

The number of visits when the cost will be equal is when we'll equate these two equations,

x + 2 = 0.25x + 5.

x - 0.25x = 5 - 2.

0.75x = 3.

x = 3/0.75.

x = 4.

At 4 visits the cost of each plan will be the same.

Answers:

==============================================

Explanation:

The two factors are (a+b+c) and (d+e+f). A factor is a part of multiplication. So in general if we multiply x and y, then x and y are factors to lead to the product x*y.

The expression a+b+c has three terms. Each term is separated by a plus sign.

The expression d+e+f also has three terms.
