1. TRUE OR FALSE and explain. The coordinate pair (-3, 7) is the solution of the system of equations made up
of y = – 3x – 2 and y - 10 = 2/3(x-6).
Answer:
FALSE, when we plug in the coordinates (-3,7) in the equation, it isn’t true. Therefore, it isn’t the solution.
Step-by-step explanation:
You plug the coordinates (-3,7) in the equation and see if it’s true
Y= -3x-2
7=-3(-3)-2
7=9-2
7=7
Y-10=2/3(x-6)
7-10=2/3((-3)-6)
-3=-7 (FALSE!!!)

The left and right page numbers of an open book are two consecutive integers whose sum is 295. Find these page numbers.
The two page numbers are IN
(Use a comma to separate answers as needed.)
Answer:
147, 148
Step-by-step explanation:
295/2=147 remainder 1 so, consecutive means back to back so 147 and 148. Add them up and you get 295.
Final answer:
The consecutive page numbers with a sum of 295 are 147 and 148, with 147 being the left page and 148 being the right page.
Explanation:
To find the consecutive page numbers of an open book with their sum equal to 295, we can set up a simple equation. Let the smaller integer be n, which means the next consecutive integer (the other page number) would be n+1. Since their sum is known to be 295, we set up the equation as n + (n + 1) = 295.
Solving for n gives us:
n + n + 1 = 295
2n + 1 = 295
2n = 294
n = 147
Therefore, the two consecutive integers are 147 and 148. The left page number is 147 and the right page number is 148.

the original plan for mr Harris's house is a rectangle that measures 40ft by 50ft. because of the increase and cost of materials, the square footage is reduced to 1739ft squared. how much will the dimensions be decreased?
Answer: The dimesions will be decreased by 13.05%.
Step-by-step explanation:
Hi, we have to calculate the original area.
Area of a rectangle = Length x width
Replacing with the values given:
A = 40x50 = 2000 ft2
Since is reduced to 1739. if we multiply the original area by a the percentage decrease, and subtract that value to the original area, we obtain 1739 ft2.
2000 - (2000x) = 1739
Solving for x
-2000x = 1739 -2000
-2000x = -261
x =-261/-2000
x = 0.1305
Multiply by 1000 to obtain the percentage:
0.1305 x 100 = 13.05%

What is the cube root of 8x^27? 2x^3 2x^9 4x^3 4x^9
Answer:
2 x^9
Step-by-step explanation:
8x ^27
We want to take the cube root
(8x ^27) ^1/3
We know that (ab)^1/3 = a^1/3 * b^1/3
(8) ^ 1/3 (x ^27) ^1/3
Re writing 8 as 2^3
(2 ^3) ^ 1/3 (x ^27) ^1/3

A bag contains only red, green, brown and yellow marbles.
The probabilities of selecting each colour are shown below.
Red = 6x
Green = 2x
Brown = x
Yellow = 4x
Find the probability of selecting a brown marble.
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.
Explanation: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.
Explanation: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
Determine the points for the graph of the relation y = -5x -3 using the x-values given in the table
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.
Rico and Halima are shopping for craft sticks, glue, and electrical tape for a science project. Together, they have $30 to spend on supplies. How should they spend their $30 if they need at least 1,000 craft sticks? 275 craft sticks is $4.75 electrical tape is $3.50, large glue is $5.00 small glue is $3.50
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.
Explanation: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:
Craft sticks cost $4.75 for 275 sticks. Hence, the cost per craft stick is $4.75/275 = $0.0173 (rounded to 4 decimal places).If they need at least 1,000 craft sticks, the minimum cost for craft sticks will be 1,000 × $0.0173 = $17.30 (rounded to 2 decimal places).Next, let's consider the cost of the other supplies. Large glue costs $5.00 and small glue costs $3.50. The electrical tape costs $3.50.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
Craft Sticks: 1,100 craft sticks (4 packs) = 4 x $4.75 = $19.00Large Glue (recommended for better bonding): 2 x $5.00 = $10.00Electrical Tape: 1 x $3.50 = $3.50Total: $19.00 + $10.00 + $3.50 = $32.50
Since $32.50 exceeds their $30 budget, they’ll need to make adjustments:
Craft Sticks: 1,100 craft sticks (4 packs) = 4 x $4.75 = $19.00Small Glue: 2 x $3.50 = $7.00Electrical Tape: 1 x $3.50 = $3.50Total: $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.
Evaluate x2 + 14 for x = –5.
Question 10 options:
A)
11
B)
39
C)
–39
D)
–11
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.
Explanation: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.

On the Moon, Jim had a weight of 27.5 lbf (27.5 pounds-force).
The force of gravity on the Moon is one sixth of that on Earth. How much did Jim weigh on Earth?
A
4.583 lbf
B 27.5 lbf
C
137.5 lbf
D
165 lbf
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.
