-5X-3Y=-7 FIND 3 POINTS THAT SOLVE THE EQUATION
Answer:
(0, 7/3), (1, 2/3), (2, -1).
Step-by-step explanation:
Input 3 x coordinates into the equation and find the y. 0, 1, and 2 will do.
-5x - 3y = -7
Substitute variable.
-5(0) - 3y = -7
Remove the term multiplied by 0.
-3y = -7
Divide by -3.
y = -7/-3
-a/-b = a/b.
y = 7/3
This makes the coordinate (0, 7/3)
-5x - 3y = -7
Substitute variable.
-5(1) - 3y = -7
Multiply.
-5 - 3y = -7
Add 5 to both sides.
-3y = -2
Divide by -3.
y = -2/-3
-a/-b = a/b.
y = 2/3.
This makes the coordinate (1, 2/3)
-5x - 3y = -7
Substitute variable.
-5(2) - 3y = -7
Multiply.
-10 - 3y = -7
Add 10 to both sides.
-3y = 3
Divide by -3.
y = 3/-3
-a/a = -1.
y = -1.
This makes the coordinate (2, -1).
pls answer from exercise 14.1 a
Answer:
b = 2a - 1
Step-by-step explanation:
a = 1 , b = 2 x 1 - 1 = 2 - 1 = 1
a = 2 , b = 2 x 2 - 1 = 4 - 1 = 3
a = 3, b = 2 x 3 - 1 = 6 - 1 = 5
a = 4, b = 2 x 4 - 1 = 8 - 1 = 7
Answer:
b = 2a - 1
Step-by-step explanation:
We can see the pattern:
1 = 1 + 0 = 1 + 1 - 1
1 = 1 - 1
3 = 2 + 1 = 2 + 2 - 1
3 = 2 + 2 - 1
5 = 3 + 2 = 3 + 3 - 1
5 = 3 + 3 - 1
7 = 4 + 3 = 4 + 4 - 1
7 = 4 + 4 - 1

Find the value of x
7-10 plsss
Answer:
Step-by-step explanation:
Hope it helps u!!
The values of x are 7) 155°, 8) 90°, 9) 140° and 10) 20°.
What is Polygons?Polygons are closed figures which has at least three set of line segments joined together.
The polygon with least number of sides is triangle.
7) It is a polygon with 4 sides (quadrilateral)
Sum of the interior angles of a quadrilateral = 360°
45° + 65° + 95° + x = 360°
x = 360° - (45° + 65° + 95°)
x = 155°
8) Sum of the interior angles of a polygon = (n - 2)180°, where n is the number of sides.
There are 6 sides.
Sum of the interior angles = (6 - 2)180° = 720°
x + 140 + 130 + 120 + 90 + 150 = 720
x = 90°
9) n = 5
Sum of the interior angles = (5 - 2) 180° = 540°
2x + 90 + 100 + 70 = 540
2x = 280
x = 140°
10) Sum of the exterior angles of a polygon is 360°.
4x + x + 98 + 162 = 360
5x = 100
x = 20°
Hence the values of x are found.

Each week Thomas will double the amount of money in his bank. What type of function is represented by this situation
Answer:
An exponential growth.
Step-by-step explanation:
We know that each week, Thomas will double the amount of money in his bank.
Let's assume that in week 0, he has an amount A of money in his bank.
After one week, in week number 1 (w = 1), the amount of money is doubled, so if we define the function M(w) as the amount of money as a function of the number of weeks, we will have:
M(1) = 2*A
After another week, in w = 2, the amount of money is doubled again, so here we have:
M(2) = 2*(M(1)) = 2*(2*A) = A*2^2
After another week, at w = 3, the amount of money is doubled again:
M(3) = 2*(M(2)) = 2*(A*2^2) = A*2^3
We already can see the pattern here, we can expect that for the week w, the amount of money in the account is given by:
M(w) = A*2^w
This is an exponential equation (an exponential growth to be more specific), so the type of function that is represented by this situation is an exponential growth.
The physician orders Keflex (cephalexin monohydrate) 0.5 g per NG tube q6h. Read the label and calculate the correct dosage.
Label reads : 250 mg per 5 mL

How many permutations of a 7-digit phone number exist if any number 0-9 may be used but repetition is not allowed?
Answer:
There are 604,800 possible permutations.
Step-by-step explanation:
The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
7 digits from a set of 10(10 digits to 0-9). So
[tex]P_{(10,7)} = \frac{10!}{(10-7)!} = 604800[/tex]
There are 604,800 possible permutations.
Answer:
10!/3!
Step-by-step explanation:
i just took a test and got it right
Because repetition is not allowed, and there are 10 initial options for the 7 decisions that need to be made, we use the formula
n!/(n-r)! = 10!/(10-7)! = 10!/3!

If you know that log5 (2) - log5 (12) = 0, which of the following is false?
ол
A log5 (x) = log5 (12)
O Blog (2 - 12) = 0
C log5 (x) = 0
ор.
2 = 12
Answer:
B
Step-by-step explanation:
A is correct because [tex]log_5(12)[/tex] was added on both sides, which is supported by the Additive Property of Equality
C is correct because the Quotient Property of Logarithms states that [tex]log_bM-log_bN=log_b(\frac{M}{N} )[/tex]
so [tex]log_5(x)-log_5(12)=log_5(\frac{x}{12} )[/tex] is correct
D is correct because using the fact that [tex]log_5x=log_512[/tex] it is easy to figure out that x=12
For B, there is no property supporting that statement.

What is the total number of outcomes for choosing a numbered card from 1 to 10 and a number on a
number cube labeled one to six?
the total number of out comes would be 16^2 or 256.
some extra things...
A numbered card from 1 - 10 would be 1 over 10 or 10% chance of picking correctly.
a number cube from 1 - 6 would be 1 over 6 or 16.66% chance of picking correctly.
if you want to combine these and pick one from both, it becomes 1 over 16 or 6.25% chance of picking both correctly.

ons he may purchase. If he saves $32 per week, write and solve an inequality to determine how many
weeks it will take for Cameron to purchase his graduation pictures.

Answer:
I dont know how to write the answer but i hope my math helped.
Step-by-step explanation:
192 divided by 32 is 6 so it will take Cameron a total of 6 weeks to get is pictures.
Answer:
32x>192
Step-by-step explanation:
I'm not 100% sure, but if you said you needed an inequality the money could be more than 192. So if you have $32 per week (x) is greater than 192 and solve, Camerson could work 6 weeks OR greater. I hope this helps :)
