Answer:
a = 1/2
Step-by-step explanation:
The given equation is :
2y=ax-7 ...(1)
The point (2,-3) lies on the graph of this equation.
We need to find the value of a.
Put x = 2 and y = -3 in equation (1)
2(-3) = a(2) -7
-6 = 2a-7
-6+7 = 2a
2a = 1
a = 1/2
Hence, the value of a is 1/2.

On which triangle can the law of cosines be used to find the length of an unknown side? Law of cosines: a2 = b2 + c2 – 2bccos(A)
Explanation:
You would use this law under two conditions:
One angle and two edges defined, while trying to solve for the third edgeALL three edges definedHence, you have your answer.
* Just make sure to use the inverse function towards the end, or elce you will throw your answer off!
_______________________________________________
Now, you would use the Law of Sines under three conditions:
Two angles and one edge defined, while trying to solve for the second edgeOne angle and two edges defined, while trying to solve for the second angleALL three angles defined [of which does not occur very often, but it all refers back to the first bullet]* I HIGHLY suggest you keep note of all of this significant information. You will need it going into the future.

C. Y=-6x-9
D. Y= -6x+9
use either the multiples method or the prime factors method to find the least common multiple of 24 and 16.
The prime factorization of 16: 16 = 2 ⋅ 2 ⋅ 2 ⋅ 2 = 24.
The prime factorization of 24: 24 = 2 ⋅ 2 ⋅ 2 ⋅ 3 = 23 ⋅ 3.
Both 16 and 24 have 23 ( 8 ) in common, so we can remove it from one of the numbers, leaving 24 and 3 . There are no more numbers in common, so the lowest common multiple is 24 ⋅ 3 = 48.
while working at the school store, john sold a jacket for $40.00 and notebooks for $1.50 each.If he collected $92.50, how many notebooks did he sell?
Answer:
35 Notebooks
Step-by-step explanation:
$1.50x35=52.5
$52.5+$40=$92.5
or $92.50 - 40=$52.5
35x1.5=52.5
Answer:
35 notebooks
Step-by-step explanation:
let notebook as be 'x'
here, $40.00+x($1.50)=$92.50
x($1.50)=$92.50-$40.00
x($1.50)=$52.50
x=$52.50/$1.50
x=35

Answer:
[tex]\frac{a+b}{a-b}=4[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{a+b}{a-b}[/tex]
Given the values
a=5b=3substituting the values in the expression
[tex]\frac{a+b}{a-b}=\frac{5+3}{5-3}[/tex]
[tex]\mathrm{Add\:the\:numbers:}\:5+3=8[/tex]
[tex]=\frac{8}{5-3}[/tex]
[tex]\mathrm{Subtract\:the\:numbers:}\:5-3=2[/tex]
[tex]=\frac{8}{2}[/tex]
[tex]\mathrm{Divide\:the\:numbers:}\:\frac{8}{2}=4[/tex]
[tex]=4[/tex]
Thus,
[tex]\frac{a+b}{a-b}=4[/tex]
A big box retailer has one order for 9 plants and 6 bushes with a cost of $390. There is a second order for 7 plants and 8 bushes with a
cost of $400.
Which system of equations can be used to determine the price of a plant, p, and the price of a bush, b?
9p +6b = 390
7p + 8b = 400
9p + 8b = 390
7p + 6b = 400
7p + 8b = 390
9p + 6b = 400
7p +95 = 390
6p+8b = 400
Answer:
Here you go( I dont feel like taking a screen shot- sorry)
Step-by-step explanation:
Very helpful for k12 students, and hope this helps! sorry I am late.
9p+6b=390
7p+8b=400

Guillermo has 6 days left to finish his summer reading project but still needs to select a book to read. He can read a maximum of 22 pages in 1 day.
Which inequality can Guillermo use to help him select a book with x pages so that he can complete the book within 6 or fewer days?
Answer:
x / 22 ≤ 6
Step-by-step explanation:
Given that :
Maximum number of pages readable per day = 22
Number of days left = 6
The book which can be completed within 6 days or fewer:
Number of readable pages per day :
(Total number of pages / maximum number of pages readable per day) ≤ number of days left
Hence, the inequality can be represented mathematically as :
x / 22 ≤ 6

Answer:
Step-by-step explanation:
3x + 5y = 7
Since that is our original form, let's convert it so that we can find the slope:
5y = -3x + 7
y = -3/5 x + y
From here, we use the point-slope equation and then convert that into slope-intercept form:
y - y1 = m(x - x1)
y - 6 = 5/3(x - 0)
y - 6 = 5/3x

Answer:
x = 3
Step-by-step explanation:
Since ∠ P and ∠ S are congruent then the triangle is isosceles and
PT = TS , substitute values
7x + 4 = 5x + 10 ( subtract 5x from both sides )
2x + 4 = 10 ( subtract 4 from both sides )
2x = 6 ( divide both sides by 2 )

Step-by-step explanation:

Which of the following statements says that a number is between -3 and 3?
Ix) = 3
Ix<3
O x > 3
Answer:
The inequality that represents this condition would be:
-3 < x < 3Step-by-step explanation:
Let x be the number between -3 and 3
Since x is between -3 and 3, so we do not have to include the integer -3 and 3 in the interval.
In inequality:
The symbol '>' is used to represent 'greater than'.The symbol '<' is used to represent 'less than'.Since the number 'x' is between -3 and 3. It means the number must be greater than -3 and less than 3.
Thus, the inequality that represents this condition would be:
-3 < x < 3The graph of the line number involving the solution -3 < x < 3 is also attached below.
Therefore, we conclude that:
[tex]-3<x<3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-3<x<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-3,\:3\right)\end{bmatrix}[/tex]
