Find the equation of the line using the point-slope formula.
Passes through the point (-9,8) and is parallel to the graph y=8/9x + 8

Answers

Answer: y-8=8/9(x-9)

Step-by-step explanation:

If it is parallel line that means that their gradient must be the same.

Point slope formula: y - y1 = m (x - x1)

m= gradient

y1 = y point

x1 = x point

The sum of two linear functions yields a new linear function. Find the sum of f(x) and g(x) given that f(x) = 3x-7 and g(x) =-10x + 1. Call this new function h(x). Write the equation for h(x) below.

Answers

Answer:

Step-by-step explanation:

in simple language h(x) = f(x)+ g(x)

=f(x) +g(x)

h(x)=(3x-7)+(-10x+1)

h(x)= 3x-10x-7+1

you rent an apartment that costs $1600 per month during the first year ,but the rent is set to go up 11.5% per year.what would be rent of the apartment during the 10th year of living in the apartment? round to the nearest tenth (if necessary ).​

Answers

Answer:

$4,750.

Step-by-step explanation:

To determine the rental value of the apartment in the tenth year, knowing that it is worth 1,600 during the first year but that it will be adjusted annually to 11.5%, the following calculation must be made:

X = 1,600 x (1 + 0.115) ^ 10

X = 4,751.91

Thus, at ten years, rounded to the nearest tenth, the rental value will be $ 4,750.

The rent of the apartment during the 10th year of living in the apartment is 4,751.9.

Rent of the apartment:

Let x represent the rent  of the apartment

Hence:

x= 1,600(1 + 0.115)^10

x=1,600(1.115)^10

x=4,751.9

Inconclusion the rent of the apartment during the 10th year of living in the apartment is 4,751.9.

Write an inequality to show the relationship between the largest and the smallest value. c. Write a statement that interprets the inequality you wrote as a statement about the relative position of those numbers on a number line.

Answers

The scores in order from the greatest to the least is 4, 3, 1, 0, -1, -2, -3.

The inequality that shows the relationship between the greatest and least number is 4 > -3.

On the number line, four is greater than -3.

What is the number listed from greatest to least?

Integers are whole numbers. It is a number without a fraction or decimal component. Integers can either be positive, negative or zero. Examples from integers are 0, -1 and 1.

The farther a positive number is from zero on the number line, the greater the positive number. The closer a negative number is to zero on the number line, the greater the negative number.

For example, 10 is greater than 4 because 4 is closer to 0 when compared to 10. -4 is greater than -10 because -4 is closer to 0 than -10 on the number line.

Here are inequality signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

The sign that would be used to show the relationship between the greatest and the least number is the greater than sign (>)

4 > -3

Order the orange juice mixtures so that the strongest tasting one is listed first.
Claire mixes 2 1/2 cups of water with 1/3 cup of orange juice concentrate.
Han mixes 1 2/3 cups of water with 1/4 cup of orange juice concentrate.

GUYS PLEASE HELP DUE TODAY :( .

Answers

Answer:

Han's mixture, Claire's mixture

Step-by-step explanation:

I figured out the percentage of orange juice for each person's mixture:

For Claire:

2 1/2 + 1/3 = 2 5/6

2 5/6 as a decimal: about 2.8

Now find what percent of Claire's total mixture was orange juice:

100 * 1/3 / 2.8 = about 11.9%

For Han:

1 2/3 + 1/4 = 1 11/12

1 11/12 as a decimal: about 1.9

Now find what percent of Han's total mixture was orange juice:

100 * 1/4 / 1.9 = 13.2%

So, Han's mixture is stronger, since his has the higher percentage of orange juice concentrate

5 7\10 × 7 4\16=????? I'm trash with multypliing ​

Answers

9514 1404 393

Answer:

  41 13/40

Step-by-step explanation:

Generally, you're told to multiply mixed numbers by converting each to an improper fraction:

  5 7/10 = (5·10 +7)/10 = 57/10

  7 4/16 = (7·16 +4)/16 = 116/16

The fractions are multiplied by multiplying their numerators to get the numerator of the result, and multiplying their denominators to get the denominator of the result.

  [tex](5\frac{7}{10})(7\frac{4}{16})=\dfrac{57}{10}\cdot\dfrac{116}{16}=\dfrac{57\cdot116}{10\cdot16}=\dfrac{6612}{160}\\\\=41+\dfrac{52}{160}=\boxed{41\frac{13}{40}}[/tex]

__

You don't have to mess with reducing the fraction of the result if you reduce the fraction 4/16 to 1/4 to begin with. Then the product is (57/10)(29/4).

_____

Alternate solution

You can also treat this as the product of two sums. The distributive property is handy for this.

  (5 + 7/10)(7 + 1/4) = (5)(7) +(5)(1/4) +(7/10)(7) +(7/10)(1/4)

  = 35 +5/4 +49/10 +7/40

  = 35 +1 +1/4 + 4 + 9/10 + 7/40 . . . . take out the integer parts

  = 40 +10/40 +36/40 +7/40 . . . . . . use 40 as a common denominator

  = 40 +53/40 = 41 13/40

Mitzi received some gourmet brownies as a gift. The wrapper said each brownie was 420 calories, and had 113 calories of fat. What percent of the total calories in each brownie comes from fat?

Answers

The percent of the total calories in each brownie that comes from fat is 26.9%

What percent of the total calories in each brownie comes from fat?

We know that the total amount of calories in each brownie is 420 calories, so that number represents our 100%, then we can write the relation:

420 cal = 100%

Now, the fat has 113 calories, this is a percentage X that we want to find, so we can write:

113 cal = X

We have the two relations:

113 cal = X

420 cal = 100%

If we take the quotient we get:

(113 cal/420 cal) = X/100%

Solving for X.

(113 cal/420 cal)*100% = X = 26.9%

So, the percent of the total calories in each brownie that comes from fat is 26.9%.

Im grateful for the calm water today because it enables me to ascend to the top level of the SS Frisia and look at the Atlantic Ocean that stretches before us until it meets the horizon. I feel the warm air on my face and smell the salty sea air, but theres a pit in my stomach when I think about how different life in New York will be.When we first set sail on August 21st, I watched until Hamburg became a miniscule speck in the distance. When I squinted and couldnt see the familiar buildings with their smoke spewing into the air anymore, Papa told me to look the other way. You cant look back, he said as he walked me to the other side of the ship, his strong arm supporting my shoulders. Home is there now. He pointed to a place that was shimmering waves of blue, and I had a hard time visualizing a home that was 6,000 kilometers of water. He told me to close my eyes and picture the skyline that would soon materialize on the horizon. I couldnt even fathom 6,000 kilometers of water, just like I couldnt fathom that our new home wouldnt be Hamburg anymore.Most of the days at sea have been turbulent; tall waves reach up from the bottom of the sea and smack into the ship, sending us to the ground whenever we are standing.
