Answer:
( - [tex]\frac{45}{19}[/tex], - 3)
Step-by-step explanation:
Given
19x = 15y and (x, - 3 ), that is y = - 3
Substitute y = - 3 into the equation
19x = 15(- 3) = - 45 ( divide both sides by 19 )
x = - [tex]\frac{45}{19}[/tex]
Which angles are corresponding angles with angle 8?
Angle4 and Angle12
Angle2 and Angle10
Angle6 and Angle14
Angle3 and Angle9
(b) Angle 2 and Angle 10 are corresponding angles with angle 8.
1. Definition of Corresponding Angles:
The pairs of angles created when a transversal crosses two parallel lines are known as corresponding angles. At every junction, these angles are at the same relative position.
2.. Identify Corresponding Angles with Angle 8:
If angle 8 is given, its corresponding angle will be in the same position but on the other side of the transversal and parallel lines.
3. Analyze the Options:
To find the angles corresponding with angle 8, you must identify which pair matches the same position as angle 8 on the other parallel line.
Option (b) Angle 2 and Angle 10 are corresponding angles with angle 8. This is because angle 2 and angle 10 are in the same relative position to the transversal and parallel lines as angle 8, thus they are corresponding angles.
Complete question:
Which angles are corresponding angles with angle 8?
a) Angle 4 and Angle 12
b) Angle 2 and Angle 10
c) Angle 6 and Angle 14

How many solutions does this system have?
y = 3/4x - 5
3x+ 4 y= -20
one
two
an infinite number
no solution
Answer:
one solution
Step-by-step explanation:
y = 3/4x - 5
3x+ 4 y= -20
Substitute the first equation into the second equation
3x+ 4 (3/4x -5)= -20
Distribute
3x +3x - 20 = -20
6x -20 = -20
Add 20 to each side
6x -20+20 = -20+20
6x = 0
x=0
We need to find y
y = 3/4x -5
y =0-5
y = -5
There is one solution
Answer:
A) one
Step-by-step explanation:
y = 3/4x - 5
3x+ 4 y= -20
3x + 4(3x/4 - 5) = -20
3x + 3x - 20 = -20
6x = 0
x = 0
y = -5
One solution: (0,-5)

find the 75th term of the arithmetic sequence -21, -10, 1 ...
Answer:
793
Step-by-step explanation:
a1=-21
d=-10-(-21)=11
an=a1+(n-1)d
a75=-21+(75-1)×11
=-21+74×11
=-21+814
=793
The 75th term of the given arithmetic sequence will be equal to 793.
What is an arithmetic sequence ?
Arithmetic sequences are groups of integers that are arranged in a particular way and share a common difference between each terms.
The sequence given is -21, -10, 1 , -- -- -- -- --
The first term of the sequence , a = -21.
We have to find out the 75th term of the given arithmetic sequence which meant , n = 75.
We know that the formula for nth term of arithmetic sequence is given by :
[tex]a_{n}[/tex] = a + ( n - 1) d
or
[tex]a_{75}[/tex] = -21 + ( 75 - 1) d
Here : the common difference 'd' will be :
d = -10 + 21
d = 11
So , the value of 75th term of arithmetic sequence will be :
[tex]a_{75}[/tex] = -21 + ( 75 - 1) × 11
[tex]a_{75}[/tex] = -21 + (74 × 11)
[tex]a_{75}[/tex] = -21 + 814
[tex]a_{75}[/tex] = 793
Therefore , the 75th term of the given arithmetic sequence will be equal to 793.

Answer:
8
Step-by-step explanation:
1) Add -11 plus 19 which should give you 8.
2) Check your answer by subtracting 8 - 19 = -11
Heya there!
Let us learn that we want that variable to be by itself.
To get the variable (b) by itself we need to do some work.
Solving for B:
As we need to get B by itself, we beed to remove the "-19".
To do that, we have to +19 since the -19 is a negative.
This allows us to have B by itself.
b - 19 = -11
+19 +19 to both sides ; whatever action we do to one side we do to the other.
Now, the equation should look like b = 8
We got b = 8 from the adding +19 to both sides. -11 + 19 = 8
Therefore, we are left with b = 8.

Chelsea shows her work in finding the solution to 40x– 5 = 2+ 3(x– 3). After
checking her answer in the original equation, she found that it did not work. Where did she make a mistake?
a. step 1: she distributed incorrectly
b. step 2: She subtracted 3x incorrectly
c. Step 3: she’s simplified incorrectly
d. step four: she subtracted 5 instead of adding 5
Answer:
The mistake that Chelsea made was that she instead of adding 5 to both sides at step 4, she subtracted them. If she added the 5 instead of subtracting it, the answer she should've gotten was -2.Answer:

WC= 15 and CO = 17, what is OW?
We know that triangle COW is a right triangle by the Tangent to a Circle Theorem.
So, we can use Pythagorean Theorem to find OW.
OW² + WC² = CO²
OW² + 15² = 17²
OW² + 225 = 289
OW² = 64
OW = 8
OW, the length of the side of the right triangle, can be found using the Pythagorean theorem. Substituting the given values into the formula and solving for OW gives a result of 8.
Explanation:The question seems to present us with a right triangle, where WC is one leg, CO is the hypotenuse, and OW is the other leg we need to find. We can use the Pythagorean theorem, which says that in a right triangle, the square of the hypotenuse (CO) is equal to the sum of the squares of the other two sides (WC and OW). In a formula, this is a² + b² = c², where c is the hypotenuse.
Substituting the given measurements into the formula we get: WC² + OW² = CO², so OW² = CO² - WC².
OW = sqrt(CO² - WC²) = sqrt((17)² - (15)²) = sqrt(289 - 225) = sqrt(64), so OW = 8.

We have that the number of observations (which is equal to the number of leaves) is 23.
23*75%=17.75.
Let us see what the 18th student studied for; 35 hours is the result.
Since the data in a stem leaf plot is in ascending order, we just need to notice the 18th leaf, reading from left to right.

Maritza rolls two number cubes that are numbered 1 through 6. What is the probability that the total on both cubes will be a prime number?
Answer: 50% Chance
Answer: 1/2
Step-by-step explanation: 2,3, and 5 are the prime numbers 1-6. That means 3/6 of those numbers are prime. 3/6 simplifies to 1/2 or 50%
Answer:
5/12 or 41.66666% or 42%
Step-by-step explanation:
There are two number cubes both listed as 1-6. In order to find the probability of the total on both cubes being a prime number, you'd have to first come up with the prime numbers possible by addition. You should get 2, 3, 5, 7, and 11.
After finding the numbers possible, you have to find each of the different number combinations that you could use to get there. You should get 15 different possibilities.
