[tex]x-5=y, xy+4=0,[/tex] then what is [tex]4x^{2} +4y^{2}[/tex]
Answer:
68
Given:
x - 5 = y ........ eq 1xy + 4 = 0 ...... eq 2Substitute equation 1 into 2
x(x - 5) + 4 = 0x² - 5x + 4 = 0x² - 4x - x + 4 = 0x(x-4) -1(x-4) = 0(x-4)(x-1) = 0x = 1, 4Find y:
y = x - 5
y = 1 - 5 (when x is 1)
y = -4
========
y = x - 5
y = 4 - 5 (when x is 4)
y = -1
Then 4x² + 4y²:
4(1)² + 4(-4)²4 + 6468Answer:
68
Step-by-step explanation:
[tex]\textsf{Equation 1}:\:x-5=y[/tex]
[tex]\textsf{Equation 2}:\:xy+4=0[/tex]
Substitute Equation 1 into Equation 2:
[tex]\implies x(x-5)+4=0[/tex]
[tex]\implies x^2-5x+4=0[/tex]
Factorize:
[tex]\implies (x-1)(x-4)=0[/tex]
Therefore:
[tex]x=1, x=4[/tex]
Substitute found values of [tex]x[/tex] into Equation 1 and solve for [tex]y[/tex]:
[tex]x=1\implies 1-5=-4[/tex]
[tex]x=4\implies 4-5=-1[/tex]
Substitute found values into [tex]4x^2+4y^2[/tex] and solve:
[tex]\textsf{For}\:(1,-4)\implies 4(1)^2+4(-4)^2=68[/tex]
[tex]\textsf{For}\:(4,-1)\implies 4(4)^2+4(-1)^2=68[/tex]
Note: As [tex]4x^2+4y^2[/tex], the values of x and y can be interchanged, so no need to input both sets of ordered pairs into the equation to solve.

Your local firefighters are having a fundraiser by selling tickets to an all you can eat pancake extravaganza. A child's ticket cost $6.50 each and an adult's ticket cost $8.50 each. They sell a total of 350 tickets and raise a total of $2695. How many children's tickets were sold?
Please Help!!
Answer:
140 child tickets were sold
Step-by-step explanation:
a = number of adult tickets
c = number of child tickets
a+c = 350
6.50 c + 8.50a = 2695
Multiply the first equation by -8.50 together
-8.50c -8.50c =-2975
Add this to the second equation to eliminate a
-8.50c -8.50c =-2975
6.50 c + 8.50a = 2695
---------------------------------
-2c + 0a = -280
Divide by -2
-2c/-2 = -280/-2
c = 140

The expression (x^22) (x^7)^3 is equivalent to x^p what is the value of p?
Answer:
p = 43
Step-by-step explanation:
(x²²)(x⁷)³
first, multiply the power of 7 times the power of 3
(x⁷)³ = x⁷ ° ³ = x²¹
second, add the power of (x²²) with (x²¹)
x²² ⁺ ²¹ = x⁴³
therefore, the value of p = 43

If a city with a population of 52,000 doubles in size every 97 years, what will the population be 291 years from now?
Answer:
156,000
Step-by-step explanation:
291 divided by 97 is 3. 52,000 x 3 = 156,000.
Population will be 6 times of present population in 291 years.
What is the population of a city ?The number of people in the city at a particular time is called population of the city.
How to find the required population ?Present population of the city = 52000
According to the problem, Population doubles in size in every 97 years.
After 97 years, the population = Double of present population
= 2 × 52000 = 104000
Population in 97 years = 104000
Population in 1 year = [tex]\frac{104000}{97}[/tex]
So, population in 291 years = [tex]\frac{104000}{97}[/tex]× 291 = 104000×3 = 312000
Population in 291 years from now = [tex]\frac{312000}{52000}[/tex] = 6 times

find the missing side
1) 6
2) 6.41
3)6.40
Answer :
6.40. (Option 3)[tex] \\ [/tex]
Step-by-step explanation :
Here, A right angled triangle is given with the measure of two sides and we are to find the measure of the third side.
We'll find the measure of third side with the help of the Pythagorean theorem,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}} \\ \\[/tex]
Here,
The base (BC) is 4 The perpendicular (AC) is 5The hypotenuse (AB) is c.[tex] \\ [/tex]
So, substituting the values in the formula we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (c {)}^{2}= (4) {}^{2} + (5 {)}^{2} }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad (c {)}^{2}= 16 + 25 }}} \\ \\[/tex]

[tex] {\longrightarrow \pmb{\sf {\qquad c = \sqrt{41} }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\frak {\qquad c \approx 6.40 }}} \\ \\[/tex]
Therefore,
The measure of the third side (c) is 6.40 .Step-by-step explanation:
As it is a right angle triangle , So
Hypotenuse = C unitsBase = 4 unitsperpendicular = 5 unitsWe have to find the value of hypotenuse i.e C

Step-by-step explanation:
Consider the polynomial -2a^3b^2+5ab^5+7b^4+8 Write the degree of this polynomial, its leading term, its leading coefficient, and its constant term.
Answers:
Degree = 6Leading term = 5ab^5Leading coefficient = 5Constant term = 8=====================================================
Explanation:
When we have multivariable terms like this, we add up the exponents for each monomial separately.
The first term -2a^3b^2 has its exponents add to 3+2 = 5The second term 5ab^5, aka 5a^1b^5, has the exponents add to 1+5 = 6The third term can be thought of as 7a^0b^4, so its exponents add to 0+4 = 4The last term 8 is really 8a^0b^0, and its exponent sum is 0The degree of this entire multivariable polynomial is the largest sum calculated in the list above. That sum being 6. Therefore, the degree of the polynomial is 6.
----------------------
From that we can circle the leading term 5ab^5 since the leading term is always the one with the largest exponent sum (aka degree). The current polynomial as written is not standard form. It should be this:
5ab^5 - 2a^3b^2 + 7b^4 + 8
Notice how the exponent sums decrease when going from left to right. The largest sum is always listed first. Hence the "leading" aspect of "leading term".
-------------------------
The leading coefficient is the coefficient of the leading term.
The coefficient of 5ab^5 is 5. More specifically, it's the first "5" mentioned. As another example, the coefficient of 7ab^5 would be 7.
The leading coefficient is 5
-------------------------
The constant is the term without any variables attached to it. It stays the same number the entire time.
The constant term is 8

O 7X= 13
O 7x=3
O 3x = 3
O 3x= 13
Answer:
3x = 3
Step-by-step explanation:
the right answer is 3x = 3
-2x + y = 8 .......(i)
5x-y =-5........(ii)
From equation (i)
y=8+2x
Putting the value of y in euation (ii)
We have,
5x-(8+2x) = -5
5x-8-2x = -5
3x=-5+8

35 is 25% of_. Do not round your answer.
Answer:
140
Step-by-step explanation:
We already have our first value 35 and the second value 25. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
35 = 25% × Y
35 = 25/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 25 we will arrive at:
Y = 35 × 100/25
Y = (35 × 100)/25
Y = 140
Finally, we have found the value of Y which is 140 and that is our answer.
Hope this is a better break down than before!
Answer:
140
Step-by-step explanation:
You can think of this as 35 = 25% of x.
25% = 0.25, so 35 = 0.25x.
You can multiply by 4 on each side to get
140 = 4(0.25)x which simplifies to
140 = x
