Answer:
x = -4, 10
Step-by-step explanation:
We take the square root and use the fact of "plus-minus" and find two values of x. The process of solving this equation is shown below:
[tex](x-3)^2 = 49\\\sqrt{(x-3)^2}=\sqrt{49}\\ x-3=+-7\\x=3+7=10\\x=3-7=-4[/tex]
Hence the two values of x are -4 and 10
Note: both (-7)^2 and (7)^2 are 49 . So we took "plus-minus" values of [tex]\sqrt{49}[/tex]

Answer:
J 36
Step-by-step explanation:
AB = 9, BC = 12, and m∠B = 90°. Since this is a right triangle, we can use Pythagorean theorem to find AC.
c² = a² + b²
c² = 9² + 12²
c = 15
So the perimeter is:
P = 9 + 12 + 15
P = 36
Abbey is stacking boxes of candles for a store display. The volume of each cube-shaped box is 125 cubic inches. If the display has six layers of boxes, how high is the display?
Answer: 30 inches
Step-by-step explanation:
We know that the formula for calculate the volume of a cube is:

How many solutions are in 7( x+2)=7x-10
7(x + 2) = 7x - 10
7x + 14 = 7x - 10
let's recall the slope-intercept form, now, both equations on each side of the equals sign have the same slope, of 7, that is a flag that both equations are parallel.
their y-intercept is 14 and -10 respectively, however that just means that one is above the other, but since they're parallel they will never touch each other and any solutions is where the graphs intersect, and for parallel lines that never happens, thus no solutions.

Answer:
B and C are geometric sequences.
Step-by-step explanation:
A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
A is not a geometric sequence because the number 1 is repeated twice in the sequence.
B is a sequence because the sequence is being multiplied by 0.5 each time.
C is a geometric sequence because it is being multiplied by 1/3 each time.
D is not a geometric sequence because it is not being multiplied each time - it is increasing by +5 (arithmetic progression - not geometric).

The correct option is (B) & (C)
What is Geometric sequence?A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
1. A is not a geometric sequence because the '1' is repeated two times in the sequence.
2. B is a geometric sequence because the sequence is being multiplied by 0.5 each time.
5/10=0.5
2.5/5=0.5
1.25/2.5=0.5
0.625/1.25=0.5
3. C is a geometric sequence because it is being multiplied by 1/3 each time.
-3/-9=1/3
-1/-3=1/3
-1/3/-1= 1/3
-1/9/-1/3= 1/3
4. D is not a geometric sequence because the multiplicative factor is not same.
Hence, 10,5, 2.5, 1.25, 0.625, 0.3125 and -9, -3, -1, -1/3, -1/9, -1/27 is geometric sequence.

kyndal wants to buy a lamp that originally cost $82, but the lamp when on sale for 20% off. the store is having an additional sale that is 40% off the sale price. what is the price of the lamp!?
Answer:
$39.36
Step-by-step explanation:
The first sale we saw, which was 20% off, needs to be applied first as the second discount is additional. With that being said, we need to multiply 82 times 80%. This is because we removed 20% of the standard 100% amount and we are left with 80%. To convert this, keep in mind 100% is equal to 1. So 80% is equal to .80 with this logic. So 82x0.8=65.6. Now we need to take 40% off of the modified price 65.6. By converting 40% off is equal to 0.60(keyword off). Now 65.6x0.60=39.36. The final price is 39.36
Plz mark me brainliest cuz then I'll answer evertything
Kyndal can buy the lamp for $39.36 after a 20% and an additional 40% discount on the original price of $82.
Explanation:To solve this problem, we need to calculate 20% of $82, then subtract that from $82 to find the sale price. Then, we need to calculate 40% of that sale price and subtract it to find the final price. Let's break it down:
Calculate 20% of $82: 0.20 * 82 = $16.40.Subtract that from the original price to find the sale price: 82 - 16.40 = $65.60.Calculate 40% of the sale price: 0.40 * 65.60 = $26.24.Subtract that from the sale price to find the final price: 65.60 - 26.24 = $39.36.

Linda had $15 in her coin bank. On her birthday, 5 relatives sent her
money as a birthday gift. Each relative sent the same amount. She
then had $115. How much money did Linda receive from each relative?
Final answer:
Linda received $20 from each of her 5 relatives, as found by subtracting her original amount from the final amount and then dividing by the number of relatives.
Explanation:
The student has asked how much money Linda received from each relative. Linda started with $15 in her coin bank and ended up with $115 after receiving equal amounts from 5 relatives. To find out how much money Linda received from each relative, you need to perform a simple subtraction to find the total amount of birthday money received, and then divide that number by 5.
Subtract the starting amount of $15 from the ending amount of $115 to find the total amount received.
Total received = $115 - $15 = $100
Divide the total received by the number of relatives to find out how much each relative gave.
Amount per relative = $100 / 5 = $20
Therefore, Linda received $20 from each of her 5 relatives.

Find the median:
3, 5, 7, 4, 3, 1
=========================================
Explanation:
Start by sorting the values from smallest to largest. This is known as ascending order. The original set {3, 5, 7, 4, 3, 1} will sort to {1, 3, 3, 4, 5, 7}
After the values are sorted, we will look at the middle most value to find the median. Because there are six items in this data set, the median number is between slot 3 and slot 4. Note how the sorted data set breaks down into
{1, 3, 3} and {4, 5, 7}
we see that 3 and 4 are tied for the middle most, so the median must be 3.5 which is halfway between 3 and 4.
Hello There!
Let’s first remember that the median is the middle number in an ordered set of data.
Our data set is
1,3,3,4,5,7
Since there are two numbers in the middle, we have to add up our two numbers in the middle which are 4 and 3 so together that gives us a sum of 7 and then we divide by 2 which we get a quotient of 3.5.

The point-slope form of the equation of the line that passes through (-5, -1) and (10,-7) is

standard form of the equation for this line?
2x-5y = -15
2-5y=-17
2x+6y=-15
2x+5v=-17
Answer:
That should be 2x + 5y = 20.
Step-by-step explanation:
First, you have to correct this: y + 7 = -⅖(x - 10). Now, first convert to Slope-Intercept Form by moving -7 to the other side of the equivalence symbol to get y = -⅖x + 4, then finally convert to Standard Form by moving ⅖x to the other side of the equivalence symbol to end up with ⅖x + y = 4.. Now, there is an extended step when it comes to fractional coefficients, and that is multiplying the whole equation by the denominator to get rid of the denominator being there in the first place, REALLY ending with 2x + 5y = 20.
BUT, if your assignment says otherwise, then the first looks correct. I hope this helps.

Lily can get 7 portions of 2/3 ounces each from the 4 2/3 ounces of saffron she bought at the Union Market.
Explanation:To calculate the number of 2/3 ounce portions that Lily can get from the 4 2/3 ounces of saffron she bought, we need to divide the total weight of saffron by the weight per portion. We can convert 4 2/3 to an improper fraction, which becomes 14/3. Next, we divide 14/3 by 2/3 to get the number of portions. Dividing fractions involves multiplying the first fraction by the reciprocal of the second. So, 14/3 ÷ 2/3 = 14/3 * 3/2 = (14 * 3) / (3 * 2) = 42/6 = 7 portions.
