Answer:
y = (-2/5)x - 2
Step-by-step explanation:
One way to attack this problem is to interchange the coefficients of x and y and change the sign of one to +: 5x - 2y = -6 becomes 2x + 5y = c. Solving for the slope, m, we get 5y = -2x + c first, and then y = (-2/5)x + D.
Subbing 5 for x and -4 for y, we now have -4 = (-2/5)(5) + D.
Then -4 = -2 + D, so that D = -2.
The desired equation is thus y = (-2/5)x - 2.
Check: Does this pass through (5, -4)? Is -4 = (-2/5)(5) - 2 true? Yes.
Is the slope -2/5 the negative reciprocal of 5/2? Yes, it is.

Charles has rolled a 6-sided die three times and it landed on 3 each time. What is the probability of getting a 3 on the 4th roll?
Answer choices: A) 1, B) [tex]\frac{1}{36}[/tex], C) [tex]\frac{1}{216}[/tex], D) [tex]\frac{1}{6}[/tex]
The answer would be D - 1/6
This is because there are six sides to the die and just because he rolled all 3s before it does not mean he has a better chance to roll a 3 now.
Since there is only 1 3 on the six sided die there is a 1/6 chance he would roll a 3.
The probability of rolling a 3 on a 6-sided die remains 1/6 regardless of previous outcomes because each roll is an independent event. Therefore, the probability of getting a 3 on the 4th roll, after it has landed on 3 for three times, is 1/6.
Explanation:The subject of this question is Mathematics, specifically probability. The question asks what the probability is that a 6-sided die, after landing on 3 for three times, will land on 3 again on the 4th roll. It is important to understand that the roll of a die is an independent event, meaning that previous rolls do not impact the outcome of subsequent rolls. Therefore, no matter what the die landed on in previous turns, the probability of getting a 3 on the next roll remains the same.
Since a die has 6 faces, each face (1, 2, 3, 4, 5, 6) has an equal chance of landing up, making the probability of getting a certain number on a die 1 out of 6 or [tex]\frac{1}{6}[/tex]. So, option D is the correct answer.

Jesse has a container that contains 18 3/4 cups of ice cream. How many 1/3 cup servings are in the container?
Jesse can serve 56 full 1/3 cup servings of ice cream from the container with a bit of ice cream remaining.
Jesse has a container that contains 18 3/4 cups of ice cream. To determine how many 1/3 cup servings are in the container, we need to divide the total amount of ice cream by the size of each serving:
First, convert 18 3/4 cups to an improper fraction: (18 × 4) + 3 = 75/4 cups.Next, divide 75/4 by 1/3, which is the same as multiplying 75/4 by 3/1 (since dividing by a fraction is the same as multiplying by its reciprocal).75/4 × 3/1 = (75 × 3) / (4 × 1) = 225/4.Simplify the fraction: 225/4 = 56.25. Therefore, there are 56 whole servings, with a little left over.Jesse can serve 56 full 1/3 cup servings of ice cream from the container with a bit of ice cream remaining.
what’s 9•1085•(17•x)
Hi!
So I believe your question is 9(1085)(17*x)
So we can start to simplify 17 and x into 17x
Next we take 17x*1085= 18,445x
And finally we multiply 18,445x*9
18,445x*9=166,005x
Factories often add filler when making meatballs sold by the bag. One factory obtained 135kg of beef from overseas. They want to add 1.3oz of filler for each pound of beef. How many ounces of filler will the factory need in order to make meatballs out of this shipment of beef?
Use 1lb = 0.45kg and do not round any computations
Answer:
The company needs 390 oz of filler.
Step-by-step explanation:
One factory obtained 135 kg of beef from overseas.
They want to add 1.3oz of filler for each pound of beef.
Given is:
0.45 kg = 1 pound
So, 135 kg = [tex]\frac{135}{0.45}[/tex] = 300 pounds
The company want to add 1.3 oz of filler for each pound of beef.
So, for 300 pounds they will need = [tex]300\times1.3=390[/tex] oz of filler.
Therefore, the company needs 390 oz of filler.

−8x+3≥27 AND−13x+5≥57
Answer:
[tex]x \leq -4[/tex]
Step-by-step explanation:
[tex]-8x+3\geq 27 and -13x+5\geq 57[/tex]
LEts solve each inequality separately. then we find the intersection of both solutions.
[tex]-8x+3\geq 27[/tex]
Subtract 3 on both sides
[tex]-8x\geq 24[/tex]
Divide both sides by [tex]-8[/tex], change the inequality symbol when we divide by negative number
[tex]x \leq -3[/tex]
Now solve the other inequality
[tex]-13x+5\geq 57[/tex]
Subtract 5 on both sides
[tex]-13x\geq 52[/tex]
Now divide both sides by [tex]-13[/tex]
[tex]x \leq -4[/tex]
Now we take the intersection of [tex]x \leq -3[/tex] and [tex]x \leq -4[/tex]
for [tex]x \leq -3[/tex], we shade the number line to the left
[tex]x \leq -4[/tex], shade the number line to the left
Intersection of both graph is [tex]x \leq -4[/tex]

Step-by-step explanation:
3t - 18 = 4(-3 - 3/4t)
3t - 18 = 4(-3 - 3/4t)
Use distributed to remove parenthesis right side
3t-18= -12-3t
Add 3t by 3t
3t+3t-18=-12
6t-18=-12
Add 18 to both sides
6t=-12+18
6t= 6
Divide 6 both sides
6t/6=6/6

8+4a+6.2-9a simplify expression
8 + 6.2 + 4a - 9a
(8 + 6.2) + (4 - 9)a
14.2 - 5a is your answer.
Answer:
Well,[tex]8+4a+6.2-9a[/tex] has like terms. The simplified expression would just be these like terms combined.
First, let's combine [tex]8[/tex] and [tex]6.2[/tex]
[tex]8+6.2=14.2[/tex]
[tex]4a-9a+14.2[/tex]
Now, combine the other two monomials.
[tex]4a-9a=-5a[/tex]
[tex]-5a+14.2[/tex] would be your answer.
Remember: Some terms can't be combined. For example, [tex]4a[/tex] and [tex]8[/tex] cannot be added together, due to the [tex]a[/tex] in [tex]4a[/tex]. These are not like terms. But [tex]4a[/tex] and[tex]-9a[/tex] are, and can indeed be combined.
