Answer:
yes
Step-by-step explanation:
Substitute x = - 8 and y = - 7 into the equation
If both sides are equal then (- 8, - 7) is a solution
left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14
right side = 2y = 2(- 7) = - 14
Since both sides are equal then (- 8, - 7) is a solution to the equation
A line passes through the points (−4,−9)
and (−2,−6) What is the equation of the line in Slope-Intercept Form?
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.
What is HCF of 5a and 15a
Please help me I don’t understand
Answer:
5a.
Step-by-step explanation:
The HCF is short for Highest Common Factor.
Write the 2 expressions in factor form:
5a = 5 * a
15a = 5 * 3 + a
Note that 5 and a are common to both sets of factors, so the HCF = 5a.
For membership to an athletic club, it costs $110 to join and $25 per month of membership. Write an equation to show the situation
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.
select all of the equations equivalent to 7x/3 = 14
A: 5x - 23 = 7
B: x - 4 = 2
C: 2x = 14
D: x - 4 = 0
Answer:
A and B
Step-by-step explanation:
I found the number that makes the 7x/3=14 statement correct that number is. Then I plugged 6 into the other equations
these were the correct ones
5•6-23=7
6-4=2
these are the wrong ones
2•6=14
6-4=0

This is because TAG is an angle that is less than 90 degrees.
Answer:
acute
Step-by-step explanation:
TAG
think of the angle, the gap is small and T is close to G
if it would be right the T would be upright
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

Step-by-step explanation:
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?
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:
$1092Step-by-step explanation:
There are 3 variables
Food, entertainment and clothing and other purchasesSaving amount is
$7 per each variable per weekTotal saving per week is
$7*3 = $21Saving per year considering 52 weeks per average year is:
$21*52 = $1092ANSWER>> DETERMINE THE RANGE OF THE FUNCTION.

A) All real numbers.
B) All integers less than or equal to -5.
C) All integers greater than or equal to -5.
D) All real numbers greater than or equal to -5.
Answer:
D
Step-by-step explanation:
When the function or the coefficient in this case 1/4x^2 is positive it means it's opening up like a u, meaning all the values will be bigger than the C term or -5 in this case.
Answer:
D
Step-by-step explanation:
the function is open-up shape, and the vertex is (0,-5)
Because it opens up, the vertex is minimum value.

Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)
Answer:
The area of the polygon CDEFGH is 7
Step-by-step explanation:
Area of a Polygon
The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.
The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:
The area CDHE is a square of length side 2. Area of a square:
[tex]A1=L^2[/tex]
The area HEFG is a trapezoid with bases lengths 4 and 2, and height 1. Area of a trapezoid:
[tex]\displaystyle A2=\frac{b1+b2}{2}h[/tex]
Calculate both areas:
[tex]A1=2^2=4[/tex]
[tex]\displaystyle A2=\frac{2+4}{2}\cdot 1=3[/tex]
Total Area=4+3=7
The area of the polygon CDEFGH is 7

Step-by-step explanation:
Let x be the number of books and y be the number of magazines you can buy. Which of the following represent(s) a possible solution to the equation 10x +4y = 40? Select all that apply.
(0, 10)
(3, 2.5)
(-2, 15)
(2, 5)
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
What do you call a relation where each element in the domain is related to only one value in the range by some rules?
please help me, i really don't know how to solve this question
Answer:
60 degrees
Step-by-step explanation:
40 degrees + 2y+20 degrees makes a straight angle. (from alternate interior angles postulate)
Thus, 2y+60 degrees = 180, or 2y = 120 degrees.
This means y = 60 degrees
An article was purchased for ₹1239 including GST of 18%. Find the price of the article before GST
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

Answer:
rewrite equation 2 for x
x=8-7y
plug in x for equation 1
3/8*(8-7y)+1/3y=17/24
solve for y
3-17/24=21/8y-1/3y
55/24 = 55/24y
y=1
sub y back into eq. 2
