Answer: 2/3
Step-by-step explanation:
Consider the pts (0, -3) and (3, -1).
change in y = -2
change in x = -3
So the slope is (-2)/(-3) = 2/3

How can you determine the number of solutions of a system by looking at the equationz
Answer:
Look at the variables and numbers in the equation, and what it equals
Step-by-step explanation:
Expressions that are the exact same have infinite solutions
[tex]5x+3=5x+3[/tex]
Expressions that are different have 1 solution
[tex]6x+7=5x-2[/tex]
Expressions that are the same with different operands have no solution
[tex]5x-3=5x+3[/tex]
Explanation:
The short of it is that when the equations are in the same form, if one equation is the same as or a multiple of the other, there are infinite solutions. If one equation is the same as or a multiple of the other, except for the constant terms, there are no solutions. Otherwise, there is one solution.
Example:
If one equation is x +2y = 3, then you can consider the other equation:
3x +6y = 9 . . . . 3 times the first equation: infinite solutions
3x +6y = 6 . . . . 3 times the first equation; constants differ: no solutions
3x -6y = 9 . . . . not a multiple of the first equation: one solution
_____
Here's a more formal method.
Put both equations of the linear system of two equations into general form:
ax +by +c = 0
dx +ey +g = 0
Perform the following arithmetic:
p = ae -db . . . . . this is called the system "determinant"
q = bg -ec
r = cd -ga
If p = q = r = 0, the equations describe the same line, so there are infinite solutions.
If p = 0 and either of q ≠ 0 or r ≠ 0, the equations describe parallel lines, so there are no solutions.
If p ≠ 0, there is one solution: (x, y) = (q/p, r/p).
_____
Additional comment
This method can always be used to find the solution to a system that is known to have one solution. It often requires fewer arithmetic operations than other solution methods. It is a variation of what is sometimes called the "cross multiplication method."
Solve - 3/5t = 15
t = -25
t = 15
t = -15
t = 25
Answer: -25
Step-by-step explanation:
-3/5t=15 mulitply both sides of the equation by -5/3.
-5/3x3/5t= -5/3x15 multiplying an even number makes it positive.
t= -5x5 multiply remaining numbers.
Answer: t = -25

What is the amplitude of the function shown in the graph?
Enter your answer in the box.
Answer:
1.5
Step-by-step explanation:
Amplitude: the height from the center line to the maximum or minimum point.
We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.
From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5
Therefore, the distance between them = -0.5 - -3.5 = 3
Divide by 2 = 3/2 = 1.5
Therefore, the amplitude = 1.5

Answer:
B. b(a) = a/6 -9
Step-by-step explanation:
Solve the given equation for b.
a = 12(b +9)/2
a = 6(b +9) . . . . simplify
a/6 = b +9 . . . . divide by 6
a/6 -9 = b . . . . subtract 9
Then the inverse relation is ...

Two kindergarteners participated in a fundraiser event "Walk
Backwards for Hunger" last weekend. John walked 2/3 of a mile and Mary
walked 3/4 of a mile. Together, they raised $93.50. How much money, each, did
John and Mary raise? Just so you know, the amount raised is proportional to
distance walked
Answer:
John = $44 Mary = $49.50
Step-by-step explanation:
2/3 + 3/4 = 17/12
17/12x = 93.5
17/12x x 12 = 93.5 x 12
17x = 1122
17x/17 = 1122/17
x = 66
2/3x = 66 x 2/3
2/3x = 44
3/4x = 66 x 3/4
3/4x = 49.5
44 + 49.5 = 93.5
John earned $44 while Mary earned $49.5.
Sorry that the explanation was long, but I hope this helps! =D

Answer:
20,000
Step-by-step explanation:
We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.
\
Answer:
the company's total budget is 20,000
Step-by-step explanation:
A company spends 13% of its month budget on rent which total $2600
Let x be the month budget on rent
13% of the month budget is 2600
13% can be written as 13/100
Now we solve for x
multiply both sides by 100
divide both sides by 13
x=20000
So, the company's total budget is 20,000

A Tom bought these 3 t shirts at the sale price of $ 14. 50. How much money did he save compared to the original total of the t shirts B what percentage of the total price did Tom save
Answer:
$2.47
14.6%
Step-by-step explanation:
Total of the original prices:
$3.99 + $6.99 + $5.99 = $16.97
He paid $14.50 for the 3 shirts.
$16.97 - $14.50 = $2.47
He saved $2.47.
The percent he saved is
2.47/16.97 × 100% = 14.6%

The senior class of Oakdale Christian School traveled 630 miles in one day on their trip to the Grand Canyon. After lunch, they traveled twice as far as they did before lunch. How many miles did they travel after lunch?
Answer:
420 miles after lunch
Step-by-step explanation:
Day 1 is 630 miles travelled - total amount of travelling.
After lunch is twice the amount of m.
Twice means 2.
So,
2xm + m (they'd have travelled) = 630 total miles
(2xm = 2m & 1m is the same as m)
2m + 1m = 630
3m = 630
÷3
m = 210 miles
Initial miles travelled before lunch was 210.
After lunch is double that amount.
Thus, 210 x 2 = 420 miles
Check:
210 + 420 = 630 miles.
Hope this helps!

z=
Answer: Look at explanation for the answer please, I am too exhausted to type the answer here
Step-by-step explanation:
y = 10sqrt(5) from the pythagorean theorem
The angle opposing z is arctan(2)
So, find z by the equation
z/y = tan(arctan(2)) = 2
z = 20sqrt(5)
And finally, find x by the pythagorean theorem
x = sqrt(1600) = 40
