x² = 12 ( take square root of both sides )
x = ± [tex]\sqrt{12}[/tex] = ± [tex]\sqrt{4(3)}[/tex] = ± ( [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] ) = ± 2[tex]\sqrt{3}[/tex]

Answer:
( 1, 35 )
Step-by-step explanation:
y=mx+c
c= y-intercept ( where the graph line crosses the cross line)
c=0
mx = gradient ( rise/run, up/across )
mx = 175/5 ( you could have picked any point in the graph )
mx = 35
the m is useless now so we discard it
y= 35x+0
if x = 1
then y = 35(1)+0
y= 35
at the coordinate x=1 y is 35

Since no percentages were provided (at least not in the ss), we have to approximate?
The space that parrots and sparrows take up is almost half the circle (we'll say 48-49%)
So, we can convert that to fraction : 48/100 or 49/100
There is 1/2 of the birds seen were either parrots or sparrows.
What is Rational number?A number which can be written in the form of fraction p / q , where q is non zero, are called Rational numbers.
Given that;
Figure shows the birds seen.
Now, We have;
By figure the half of circle is shown either parrots or sparrows.
Hence, The value of fraction of the birds seen were either parrots or sparrows is,
⇒ 1/2 of 100%
⇒ 1/2 × 100/100
⇒ 1/2
Therefore, The value of fraction of the birds seen were either parrots or sparrows is, 1/2

3x + 2y = 12
Answers
Answer: Since −3x does not contain the variable to solve for, move it to the right-hand side of the equation by adding 3x to both sides.
y=5x−7
−2y=3x−12
Divide each term in the equation by −2.
y=5x−7
y=−3x/2+6
Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.

Step-by-step explanation:
Area of figure I = length * width
= 8 *16
= 128 cm²
Area of figure II = length * width
= 4 * 3
= 12 cm²
Trianlge:
base = b = 7 cm
height = 4 + 4 + 6 = 14 cm
[tex]\text{area of triangle =$\dfrac{1}{2}*b*h$}[/tex]
[tex]= \dfrac{1}{2} * 7 * 14[/tex]

Step-by-step explanation:
The square of 2 plus the prime number 13 add up to 17
[tex]2^{2}+13=4+13 =17[/tex]
Hope this helps
Answer:
Square number = 4
Primer number = 13
Step-by-step explanation:
A square number is the result when a number has been multiplied by itself.
A prime number is a whole number greater than 1 that only has two factors, itself and 1.
List all the square numbers and prime numbers below 17:
Square numbers: 1, 4, 9, 16, ...
Prime numbers: 2, 3, 5, 7, 11, 13, ...
Therefore, the only combination of square number and prime number that sums to 17 is: 4 + 13 = 17
Solution
Square number = 4
Primer number = 13

Members of a softball team raised $1319.25 to go to a tournament. They rented a bus for $776.50 and budgeted $41.75 per player for meals. Write and solve an equation which can be used to determine pp, the number of players the team can bring to the tournament.
Answers
Answer:
13 players
Step-by-step explanation:
Money Raised=RentedBus+Meals
1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.

Answers
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.

how do i find the vertex of y= -4x^2-16x+1 ?
Answers
Answer:
(-2, 17)
Step-by-step explanation:
the first step you can do to find the vertex is to find the axis of symmetry
the equation for that is -b/2a
-(16) / 2(-4)
-16 / 8 = -2
the axis of symmetry is x =-2 so you plug in -2 to the equation
-4(-2)^2 - 16(-2) + 1
-4(4) + 32 + 1
-16 + 33
17
the vertex is (-2, 17)
