Answer:
y = -1
(and x = 3)
Step-by-step explanation:
5x + 3y = 12
4x - 5y = 17
First, we'll solve for x in terms of y
5x = 12 - 3y
x = 12/5 - 3/5y
x = 2.4 - 0.6y
Then substitute that mess into the next equation:
4(2.4 - 0.6y) - 5y = 17
and solve for a numerical value of y
9.6 - 2.4y - 5y = 17
-7.4y = 7.4
y = -1
To finish and check, we can use that to solve for x:
x = 2.4 - 0.6(-1)
x = 2.4 + 0.6
x = 3
And check both values in the original equations.
5x + 3y = 12
4x - 5y = 17
5(3) + 3(-1) = 15 - 3 = 12
4(3) - 5(-1) = 12 +5 = 17

b. because its the L in the cearl bowl
Answer:
g (grams)
Step-by-step explanation:
Example
Jesse needs to decide which metric unit he should use to weigh a bowl of books and documents.
First, think about the size and weight of the objects in the bowl.
Milligrams would be far too small of a unit. The books alone would probably weigh a few million milligrams. Even grams is really not ideal, since the total weight would be thousands of grams.

How many solutions does the system of linear equations have? Choose the best answer.
2x + 4y = 3
2x + 4y = 9
Answer:
The system of linear equations will have infinite solutions.
Step-by-step explanation:
This is because, this system of linear equations is in 2 variables, x & y. Any number can be substituted in their place. So, infinite solutions can be made.

The tangent of angle B is __
Answer:
[tex]\frac{\sqrt{95} }{7}[/tex]
Step-by-step explanation:
The tangent is equal to the opposite/adjacent
the opposite of angle b is √95 and the adjacent of angle b is 7 so the tangent of angle b is [tex]\frac{\sqrt{95} }{7}[/tex]

how does the Torah affect Jewish life today !!!!!!!
i will give brainlisttttt
Answer:
the Torah plays a big part in the lives of Jews today as it is believed to be the word of God. All Jews use the Torah to help guide them in their lives, but some Jews use the Torah more strictly than others. For example, some Orthodox Jews believe that it is important to follow every single rule in the Torah. However, Reform Jews tend to follow the rules they feel are most important and disregard some rules they see as outdated.
The significance of the Torah is seen in many ways:
It is read aloud weekly at the synagogue. It takes a year to recite the whole Torah.
The festival of Shavout celebrates God’s revelation of the Torah to Moses.
The commandments in the Torah shape the way that Jews live their lives today.

g(x) = -
A. g(x) = (x+4)2 - 2
B. g(x) = (x-4)2 + 2
C. g(x) = (x - 4)2 - 2
D. g(x) = (x+4)2 + 2
Answer:
A
Step-by-step explanation:
Keep in mind that when transformations involve squares, they usually move the opposite direction of when they don't according to the function. So (x-4) moves left, but (x-4)2 moves right. same with up and down

No Solution, One Solution, or Infinitely
Answer:
Infinitely
Step-by-step explanation:
Hi,
Both sides of the equation are equal to each other, this means they're the exact same line and overlap. This is infinitely many solutions.
Hope this helps :)
Answer:
Infinitely
Step-by-step explanation:
-6p+7=7-6p can be reshuffled to read: -6p+7=-6+7. Both sides of the equation are the same, so there are infinite solutions.

2. The measure of an interior angle of a regular polygon is 160 degrees. Find the number of sides in the
polygon
Answer:
18 sides
Step-by-step explanation:
(N x 180) - 360 = 160N
180N -360 = 160N
20N = 360
N = 18
Proof:
(18 x 180) -360 = 2880 total degrees
2880/18 sides = 160°

Question 10 (2 points)
Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP
Answer:
a = 2
Step-by-step explanation:
To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!
The Pythagorean Theorem states:
a^2 + b^2 = c^2
Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)
a^2 + 2.1^2 = 2.9^2
Finally, we solve our equation (hint: use the calculator if needed)
a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)
a = 2 (Now that's the final answer!)
