Answer:

acute

Step-by-step explanation:

TAG

if it was straight T would lay flat corresponding to G making a line

if it was obtuse the gap would surpass the right angle outward

For membership to an athletic club, it costs $110 to join and $25 per month of membership. Write an equation to show the situation

Answers

Answer:

110 + 25x = Total Cost (or any type of variable needed, like a,b,c, etc.)

Step-by-step explanation:

Since the monthly fee occurs more than once, and we don't have the number of months, we put an x to represent the amount of months. The $110 is the one time additional fee for the membership, so it doesn't need a variable.

In the process of making a financial forecast, Farid has been looking closely at his
variable expenses. Currently, each week he spends an average of $25 on food, $30 on
entertainment, and $40 on clothing and other purchases. If Farid reduced his variable
expenses in each of these three categories by $7 a week, how much would he save
over the course of one year?

Answers

Answer:

1092

Step-by-step explanation:

first calculate expense for each week;

25+30+40= 95

expense after saving

25-7= 18

30-7=23

40-7=33

18+23+33= 74

total saving for each week= 95-74=21

(you can also just do 7*3=21 to know total saving each week)

weeks in a year=

365 days/7= 52.14 = 52 weeks

total savings for the year= 52*21=$1092

Answer:

$1092

Step-by-step explanation:

There are 3 variables

Food, entertainment and clothing and other purchases

Saving amount is

$7 per each variable per week

Total saving per week is

$7*3 = $21

Saving per year considering 52 weeks per average year is:

$21*52 = $1092

An article was purchased for ₹1239 including GST of 18%. Find the price of the article before GST

Answers

Answer:

₹1015.98

Step-by-step explanation:

Given parameters:

 Selling price of article =  ₹1239

GST = 18%

Unknown:

Price of the article before GST = ?

Solution:

To find the price of the article before GST, we simply take away the percentage cost of the GST;

   GST = [tex]\frac{18}{100}[/tex] x  ₹1239 =  ₹223.02

Now, cost before including GST;

    =  ₹1239 -  ₹223.02

   =  ₹1015.98

Answers

Step-by-step explanation:

so what you are going to do is subsitute all the x axis coordinates with the x in the equation they gave you and then do the same with the y for example A.

10(0)+4(10)=40

Answer:

(0, 10)

Step-by-step explanation:

substitute the value of x,y given into the formula, that equates 40.

10x + 4y = 40

let x = 0, y = 10  ;         10(0)  + 4(10)   = 40    

let x = 3, y = 2.5 ;         10(3)  + 4(2.5) ≠ 40     x

let x = -2, y = 15  ;         10(-2) + 4(15)   ≠ 40    x

let x = 2, y = 5     ;        10(2)   + 4(5)    ≠ 40    x

therefore, (0, 10) is the right answer

A line passes through the points (−4,−9)
and (−2,−6) What is the equation of the line in Slope-Intercept Form?

Answers

Answer:

D. [tex] y - 5= 3(x - 1) [/tex]

B. [tex] y = \frac{3}{2}x - 3 [/tex]

Step-by-step explanation:

Problem 1:

Point-slope form equation is given as [tex] y - y_1 = m(x - x_1) [/tex], where, (x1, y1) is a point on the line, and m = slope.

Find the slope of the line of the graph given, using 2 points on the line, points (0, 2) and (1, 5).

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{0 - 1} = \frac{-3}{-1} = 3 [/tex]

Substitute (x1, y1) = (1, 5) and m = 3 into [tex] y - y_1 = m(x - x_1) [/tex]

[tex] y - 5= 3(x - 1) [/tex]

The answer is D.

Problem 2:

Slope-intercept equation takes the form: [tex] y = mx + b [/tex], where, m = slope, and b = y-intercept.

Find m and b.

Given, points (−4,−9) and (−2,−6),

[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-6 -(-9)}{-2 -(-4)} = \frac{3}{2} = \frac{3}{2} [/tex]

Substitute x = -2, y = -6, and m = ³/2 into [tex] y = mx + b [/tex], to find b:

[tex] -6 = \frac{3}{2}(-2) + b [/tex],

Subtract b from both sides

[tex] -6 = -3 + b [/tex]

Add 3 to both sides

[tex] -6 + 3 = b [/tex]

[tex] -3 = b [/tex]

[tex] b = -3 [/tex]

Substitute m = ³/2, b = -3 into [tex] y = mx + b [/tex]

[tex] y = \frac{3}{2}x + (-3) [/tex]

[tex] y = \frac{3}{2}x - 3 [/tex]

The answer is B.
