Answer:

(3,-3)

y= -3

x= 3

Step-by-step explanation:

5x+2y=9

2x-3y=15

solve the equation

x=9/5-2/5y

2x-3y=15

substitute the value of x into an equation

2(9/5-2/5y)-3y=15

distribute

18/5-4/5y-3y=15

subtract -4/5 to -3

18/5-19/5y=15

subtract 18/5 from both sides

-19/5=57/5

divide both sides by -19/5

y= -3

substitute the value of y into an equation

x=9/5-2/5(-3)

distribute

x=9/5+6/5

add 9/5 to 6/5

x=3

Answer:

If that's x^2 + 14,the answer is B. 39

but if it's x2 + 14 | 2x + 14 = 24

Step-by-step explanation:

x^2 + 14

= (-5)^2 + 14

= 25 + 14

=39

x2 + 14 | 2x + 14

=2(-5) + 14

=10 + 14

=24

After substituting x=-5 into the equation x² + 14 and performing the operations, we get the answer as 39.

The question asks us to evaluate the expression x² + 14 when x = -5.

Firstly, replace x in the equation with -5. So the equation becomes (-5)² + 14.

Perform the square operation to get 25, and then add the 14. This results in 25 + 14 = 39.

So, when you substitute x = -5 into the expression x² + 14, you get the result 39. Therefore, x² + 14 for x = -5 equals 39.

Find the slope

Y= -4/3x+2

The slope is -4/3 because that's the number before x.

Answer:

50%

Step-by-step explanation:

There are 4 suits in a deck of cards, hears diamonds clubs and spades

2 are red and 2 are black

This means 1/2 of the cards are black and 1/2 are red

P (black) = black cards / total cards

               = 1/2

               = 50%

To find the probability of selecting a brown marble, sum the total probability for all marble colors, solve for x, and then use the value of x to get the probability for brown which is 1/13.

The question involves calculating the probability of selecting a marble of a certain color from a bag containing marbles of different colors, each with a different probability of being chosen. In this particular problem, we are given that the probabilities of selecting red, green, brown, and yellow marbles are 6x, 2x, x, and 4x, respectively.

Since these are the only colors in the bag, their probabilities must add up to 1 (the total probability), so:

6x + 2x + x + 4x = 1

Summing the multiples of x, we get:

13x = 1

Solving for x gives:

x = 1/13

We can now find the probability of selecting a brown marble, which is just x:

Probability of brown = x = 1/13.

The probability of selecting a brown marble from the bag can be found by dividing the number of brown marbles by the total number of marbles in the bag, which is 1/13.

The probability of selecting a brown marble can be found by dividing the number of brown marbles by the total number of marbles in the bag. Since the bag contains four different colors of marbles, the total number of marbles is 6x + 2x + x + 4x = 13x. The number of brown marbles is x. So, the probability of selecting a brown marble is:

P(Brown) = x / (6x + 2x + x + 4x) = x / 13x = 1/13

Your Answer is :

-18+18v

Answer:

(-2,7) , (-1,2) , (0,-3) , (1,-8) , (2,-13)

Step-by-step explanation:

For the first one,

y = -5x - 3

We can substitute the x value:

y = -5(-2) - 3

Then just simplify

y = 10 - 3

y = 7

Then you would get the coordinates: (-2,7)

You probably had the same approach but put the numbers in the wrong order. The third option would be correct.

Answer:

Jim had a weigh 165 lbf on Earth.

Step-by-step explanation:

Weight:

The product of mass and acceleration due to gravity.

weight= mass× g

Mass: The amount of material in an object is known as mass of the object.

Mass does not depends on g. Mass of an object remains same.

Given that,

Jim had a weight of 27.5 lbf on the moon.

So,

[tex]mg_m=27 \ lbf[/tex] .......(1)

m = mass of Jim

[tex]g_m[/tex]= acceleration due to gravity on the moon.

Again,

The value of force of gravity on the Moon is one sixth of that on Earth.

[tex]g_m=\frac16 g[/tex]

g =  force of gravity on Earth.

Now plug [tex]g_m=\frac16 g[/tex] in equation (1)

[tex]m\times\frac16 g =27 \ lbf[/tex]

[tex]\Rightarrow mg=(27\times 6) \ lbf[/tex]

⇒mg = 165 lbf

Jim had a weigh 165 lbf on Earth.

The correct mathematical sentence to represent the situation where the temperature at 10:00 pm (T), if reduced by 5 degrees, would break the record-low of 26 degrees, is T - 5 < 26, which is Option A.

The mathematical expression that represents the situation where Austin checks the temperature at 10:00 pm, and if it falls by 5 more degrees it will break the record-low temperature for that date, which is 26 degrees. The correct mathematical sentence that expresses this information is:

T - 5 < 26

This is because if the temperature at 10:00 p.m., represented by T, falls by 5 degrees and becomes less (<) than 26 degrees, it would break the record-low temperature.

Therefore, the answer is Option A.

Rico and Halima should spend $17.30 on craft sticks and evenly distribute the remaining $12.70 between large glue, small glue, and electrical tape.

To determine how Rico and Halima should spend their $30 on craft sticks, glue, and electrical tape, we need to calculate the cost of each item and ensure they have enough money to buy at least 1,000 craft sticks. Let's break it down:

To determine the remaining amount, they can spend on glue and electrical tape, we subtract the minimum cost of craft sticks from their total budget: $30 - $17.30 = $12.70.

Now we need to decide how much to spend on large glue, small glue, and electrical tape. Since we don't have specific quantities required for each item, let's assume they spend an equal amount on large glue, small glue, and electrical tape.

Therefore, each item can cost $12.70/3 = $4.23 (rounded to 2 decimal places).

Rico and Halima should buy 1,100 craft sticks, two small glues, and one electrical tape for a total of $29.50, staying within their $30 budget.

Here’s a breakdown of how they can spend their money:

Purchase Plan

Total: $19.00 + $10.00 + $3.50 = $32.50

Since $32.50 exceeds their $30 budget, they’ll need to make adjustments:

Total: $19.00 + $7.00 + $3.50 = $29.50 (within budget).

Therefore, Rico and Halima should buy 1,100 craft sticks, two small glues, and one electrical tape for a total of $29.50.
