what is y 5(y -10)=-5
Answers
Answer:
y=9
Step-by-step explanation:
5(y-10)=-5
We move all terms to the left:
5(y-10)-(-5)=0
We add all the numbers together, and all the variables
5(y-10)+5=0
We multiply parentheses
5y-50+5=0
We add all the numbers together, and all the variables
5y-45=0
We move all terms containing y to the left, all other terms to the right
5y=45
y=45/5
y=9
The value of y = 9 is correct. Therefore, the solution is y = 9.
To solve the equation 5(y - 10) = -5 for y, follow these steps:
Step 1: Distribute the 5 on the left side of the equation:
5y - 50 = -5
Step 2: Move the constant term to one side by adding 50 to both sides:
5y - 50 + 50 = -5 + 50
Step 3: Simplify the left side and evaluate the right side:
5y = 45
Step 4: Isolate y by dividing both sides by 5:
5y / 5 = 45 / 5
Step 5: Simplify and calculate y:
y = 9
The solution to the equation is y = 9. To verify, substitute y with 9 in the original equation:
5(9 - 10) = -5
5(-1) = -5
-5 = -5
Since both sides are equal, the value of y = 9 is correct. Therefore, the solution is y = 9.

Sides of a triangle are of the ratio 2:3:4. If the perimeter of the triangle is 90 cm, what is the area of the triangle?
Answers
Answer:
this might help you....
The area of a triangle with ratio of 2:3:4 and a perimeter of 90 centimeter is 290. 47 centimetre squared.
What is perimeter of a triangle?The perimeter of a triangle is the sum of the whole sides of the triangle.
Therefore, the perimeter is given as follows:
perimeter = 90 cm
Hence, the sides can found as follows:
2 / 9 × 90 = 20 cm
3 / 9 × 90 = 30 cm
4 / 9 × 90 = 40 cm
Area = √s(s-a)(s-b)(s-c)
where
a, b and c are the sidess = semi perimeterHence,
s = 90 / 2 = 45
a = 20 cm
b = 30 cm
c = 40 cm
Therefore,
area of the triangle = √45(45 - 20)(45 - 30)(45 - 40)
area of the triangle =√45(25)(15)(5)
area of the triangle = √84375
area of the triangle = 290.473750966
area of the triangle = 290. 47 cm²

Graphs of functions on the interval [0, 4] are depicted below. For each function, find its maximum and minimum values.
The maximum value is:
The minimum value is:
Answers
Answer:
To find the extremes, we must see the graph.
The maximum will be the value where the value of y is the greatest.
We can see that the graph peaks at y = 3.
Then the maximum is 3.
The minimum is the value of y that is the lowest.
We can see that in the left side, when x = 0, y takes the lowest value, y = -1
Then the minimum in the interval is -1.
The easier way to see maximum/minimum value is to look at the highest/lower value in the graph.

What is long division method?Long Division is a method for dividing large numbers, which breaks the division problem into multiple steps following a sequence. Just like the regular division problems, the dividend is divided by the divisor which gives a result known as the quotient, and sometimes it gives a remainder too.
Given that, one factor of the polynomial 6x³-x²+ 8x+5 is (2x+1).
Using long division method, we get
2x+1|6x³-x²+8x+5|3x²+2x-5
(-)6x³+3x²

-4x²+8x+5
4x²+2x

Now, the factors of quotient 3x²+2x-5 are
3x²+5x-3x-5
= x(3x+5)-1(3x+5)
= (3x+5)(x-1)
Therefore, the other factor of the polynomial (3x+5) and (x-1).

Which two numbers of the given data set have the same absolute value? Explain your answer in full sentences.
-5, 5, -3, 8
pls help. ;)
Answers
Answer:
The answer is -5 and 5 because when you do absolute value if there is a negative number then it turns into a positive number. Negatives will always turn out as positives when doing absolute value. :)
Step-by-step explanation:
Answer: the two numbers that have the same absolute value is -5, and 5.
Step-by-step explanation:
Absolute will just make any negatives to positive.
So, the absolute value of -5 is 5, or the absolute value of -3, is 3.
If it's already positive, then nothing happens; it stays the same
So, the absolute value of 8 is 8, nothing is changed.
