c 5z + 5
d 5 – z

Answer:

A graph has month on the x-axis and saved (money) on the y-axis. Points are at (0, 3,000), (2, 2,450), and (5, 1,625).

The instructor’s friend also plans to rent an apartment in the same complex. Use the graph to identify the y-intercept and the slope used to write the equation in slope intercept form.

y-intercept =

✔ 3000

Slope =

✔ –275

Linear equation =

✔ y = -275x + 3000

Step-by-step explanation:

The linear equation which models the data represented by the graph written is slope - intercept form is :y= - 275x + 3000

General form of a slope - intercept equation :

Slope = Rise / Run

The slope, b:

Slope = (1375 ÷ -5) = - 275

The intercept, c:

This is the point on the graph where the trend line crosses the y-axis.

Hence, the intercept is 3000

Therefore, the slope - intercept equation is y= - 275x + 3000

Answer: Orlando mixed five pounds of cereal squares and 25 pounds of nuts.

Answer:

5 lbs cereal squares.

25 Ibs nuts.

Step-by-step explanation:

Let x be the weight of nuts in pounds and y be the weight of cereal squares in pounds.

Total weight of the party mix is 30 pounds.

[tex]x+y=30[/tex]              ..... (1)

It is given that,

Cost of nuts = $7 per pound

Cost of cereal = $4 per pound

The cost of mix = $6.50 per pound.

[tex]7x+4y=6.50\times 30[/tex]

[tex]7x+4y=195[/tex]          ..... (2)

Substitute the value of x in equation (2) from equation (1).

[tex]7(30-y)+4y=195[/tex]

[tex]210-7y+4y=195[/tex]

[tex]-3y=195-210[/tex]

[tex]-3y=-15[/tex]

Divide both sides by -3.

[tex]y=5[/tex]

Substitute y=5 in equation (1).

[tex]x+5=30[/tex]

Subtract both sides by 5.

[tex]x=30-5[/tex]

[tex]x=25[/tex]

Therefore, he use 25 lbs of nuts and 5 lbs cereal squares for party mix.

Answer:

x = - 2

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4

Equating to zero, that is

x² + 4x + 4 = 0 ← left side is a perfect square

(x + 2)² = 0, thus

x + 2 = 0 ⇒ x = - 2

Answer:

[tex]\boxed{\text{x = -2}}[/tex]

Step-by-step explanation:

ƒ(x) = x² - 2x

g(x) = 6x + 4

(f + g)(x) = x² - 2x + 6x + 4 = x² + 4x + 4  

[tex]\begin{array}{rcr}x^{2} + 4x + 4 & = & 0\\(x + 2)^{2} & = & 0\\x+2 & = & 0\\x & = & \mathbf{-2}\\\end{array}[/tex]

Answer:

6

Step-by-step explanation:

The digit in the hundredth place value of 6.02 is 2, so it rounds down.

The number 6.02, when rounded to the nearest tenth, results in 6.0, as '2' in the hundredths place is less than '5' and requires rounding down.

Given the number 6.02, rounding to the nearest tenth means identifying what tenth it is closest to. The number in the tenths place is '0'. For rounding, we look at the digit following the tenths place, which is the hundredths place. Here, the number is '2'. If this number is 5 or more, we round up. If it's 4 or less, we round down. So, 6.02 to the nearest tenth, would be 6.0 because 2 is less than 5, so we round down.

8x-12+12= 4x+12

8x=4x+12

move 4x to the other side.

sign changes from +4x to -4x

8x-4x= 4x-4x+12

8x-4x= 12

Final answer:

Cindy drew a total of 312 pictures over two years, calculating from three pictures per week for 52 weeks each year, then doubling the result for the two years.

Explanation:

To calculate the total number of pictures Cindy drew over two years, we start by determining the number of pictures she draws each week.

Since Cindy draws three pictures each week, we multiply that number by the number of weeks in one year.

There are 52 weeks in one year.

So, the number of pictures Cindy draws in one year is:

Since the question is about a two-year period, we multiply the annual amount of pictures by two:

Therefore, Cindy drew a total of 312 pictures over two years.

Answer:

A. 7.2 centimeters

Step-by-step explanation:

The length of the base is 7.2 centimeters. The area of a rectangle is length*width

The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.

The working is as follows :

Area = 90 cm²

Height = 12.5 cm

Length = ?

Length = Area ÷ Height

= 90 ÷ 12.5

= 7.2cm

The length of the base of the rectangle is found by dividing the area by the height, which gives 7.2 centimeters.

The subject is about finding the length of the base of a rectangle given its area and height. The formula to find the area of a rectangle is Area = Length x Width. From the question, we know the Area is 90 square centimeters and the height (which can also be considered as the Width) is 12.5 centimeters. Therefore, we can arrange the formula to solve for Length: Length = Area / Width.

Substituting the given numerical values we find: Length = 90 / 12.5 = 7.2 centimeters. So, the correct answer is 7.2 centimeters (Option A).

Option 2 is correct.

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]

To find the equation of a line that is parallel to the given line and passes through the point (-2, 2), we follow these steps:

1. Determine the slope of the given line. Parallel lines have the same slope.

2. Use the point-slope form of a line equation with the given point and the determined slope to find the equation of the parallel line.

From the graph, we can see that the given line passes through points (0, -3) and (-5, -4). To find the slope (m) of the line, we use the slope formula:

[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

Substituting the given points, we get:

[tex]\[ m = \frac{-4 - (-3)}{-5 - 0} \][/tex]

[tex]\[ m = \frac{-4 + 3}{-5} \][/tex]

[tex]\[ m = \frac{-1}{-5} \][/tex]

[tex]\[ m = \frac{1}{5} \][/tex]

Now we have the slope of the parallel line, which is[tex]\( \frac{1}{5} \)[/tex]. The point-slope form of the line equation is [tex]\( y - y_1 = m(x - x_1) \)[/tex]. Plugging in the slope and the point (-2, 2), we get:

[tex]\[ y - 2 = \frac{1}{5}(x - (-2)) \][/tex]

[tex]\[ y - 2 = \frac{1}{5}(x + 2) \][/tex]

Now we simplify and solve for  y  to put it in slope-intercept form ( y = mx + b ):

[tex]\[ y - 2 = \frac{1}{5}x + \frac{2}{5} \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + 2 \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + \frac{10}{5} \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]

So the equation of the line that is parallel to the given line and passes through the point (-2, 2) is:

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]

Step-by-step explanation:

[tex]x^{2} <5 => -\sqrt{5}< x < \sqrt{5}[/tex]

Answer:

[tex]-\sqrt{5} <x<5[/tex]

Step-by-step explanation:

The given expression is

[tex]x^{2} -5<0[/tex]

To solve this quadratic inequality, we need to isolate the variable and then apply the quadratic root at each side of the inequality, as follows

[tex]x^{2} <5\\x<\±\sqrt{5}[/tex]

Remember that a quadratic root has two results, one positive and one negative, which in this case would be

[tex]x<\sqrt{5}\\ x>-\sqrt{5}[/tex]

Remember that a negative factor changes the direction of the inequality relation to the opposite.

Therefore, the solution is

[tex]-\sqrt{5} <x<5[/tex]

That is, all values between [tex]-\sqrt{5}[/tex] and [tex]\sqrt{5}[/tex].

Percentage means how much per hundredth.

we can write 20% as `1/5 in fraction. when we multiply a fraction by 100 we get the result in percentage.

In the given question

Explanation:

As we have given the data  in the question that  

Weight of marry = n kg

Weight of Marry sister = n-15 kg

Let Marry be ‘K' times heavier than her sister then it means that  

K=[tex]\frac{n}{(n-15)}[/tex]
