1) 4x + 9 = 2x - 6
Subtract 9 from both sides
4x = 2x - 15
Subtract 2x from both sides
2x = -15
Divide both sides by 2:
x = -15/2 or -7.5
2) 2(x - 5) = 5x + 23
Expand the brackets:
2x - 10 = 5x + 23
Subtract 23 from both sides
2x - 33 = 5x
Subtract 2x from both sides
3x = -33
Divide both sides by 3
x = -11
3) 7x + 3 = 2x + 13
Minus 3 from both sides
7x = 2x + 10
Subtract 2x from both sides
5x = 10
Divide both sides by 5
x = 2

Desiree wants to place a wire fence around the base of an apple tree... The tree has and mulch area around it, is shaped like a circle that has a radius of 14 inches... What length of fencing does Desiree need? ROUND TO THE NEAREST TENTH AND INCLUDE UNITS IN YOUR ANSWER
Answer:
( About ) 88 inches
Step-by-step explanation:
Considering this wire fence to be the circumference of the base of this apple tree, provided it is circular, let us solve for the amount of fencing given the radius of this circle is 14 inches;
[tex]Radius Of Circle - 14 inches,\\Diameter - 14 inches * 2 = 28 inches,\\Circumference - 2\pi r, r = radius,\\\\2\pi r - \pi d, d = diameter,\\\\Circumference Of Circle - \pi * ( 28 inches ) = ( About ) 88 inches\\Length Of Fencing = ( About ) 88 inches[/tex]
Length of Fencing rounded to 10th place, ( About ) 88 inches
Solve systems of equations for x + y, please!! -2x - 7y = -13 3x + 6y = 15
Answer:
-2x - 7y = -13. X intercepts = (13/2,0)
3x+6y=15. Y intercept = (0,13/7)
Step-by-step explanation:
-2x-7y=-13. To find x intercept substitute 0 for y and solve for x.
3x+6y=15. To find y intercept substitute 0 for x and solve for y.

What is the length of RP?
Answer:
RP = 14
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(x+x+2) * (x+2) = (4+6)*4
Combine like terms
(2x+2)(x+2)=10*4
2(x+1)(x+2) = 40
Divide by 2
(x+1)(x+2) = 20
FOIL
x^2+2x+x+2 = 20
x^2 +3x+2 =20
Subtract 20
x^2 +3x-18 = 0
Factor
(x +9) (x-6) = 0
Using the zero product property
x+9=0 x-6 =0
x= -9 x=6
Since the length cannot be negative
x=6
RP = x+2+x = 6+2+6 = 14

David's monthly house payment is $468 21.
If his annual real estate tax is $1,231 and his annual insurance is $1,087, what is his total
payment to the lender each month?
Round each answer to the nearest dollar before adding
Hence total payment for expenses is $46281
What is Total payment?Payments refers to outstanding amount to be paid for the liable items. We can also say that banknotes and coins (cash), as well as deposits and credit on an account with a financial institution or a similar entity that can be run using payment instruments, are all examples of means of payment.
How to solve?annual real estate tax = $1,231
annual insurance = $1,087
David' monthly house payments=$46821
To calculate total payments we will now add all the payments.
Hence total payments=$49,139

Using the image below, solve for . Make sure to double check your work at the end.
Step-by-step explanation:
They are Alternate angles so they need to be equal to each other meaning you can right them like this;
[tex]4x + 2 = 86[/tex]
So to work out x you just have to separate x;
[tex]4x = 86 - 2 \\ 4x = 84 \\ x = \frac{84}{4} [/tex]
So

Sort the polynomials according to whether they are prime or non-prime.
6x3 - 5x2 + 2x-14
124 - 18x2 + 8x2 - 12
6x2 + 9x + 10x + 15
1272 - 3x + 4x +7
Answer: first, second and fourth are primes, the third is not-prime.
Step-by-step explanation:
A prime polynomial can not be reduced.
Let's see the options:
A) 6x^3 - 5x^2 + 2^x-14
You can see that we have a coefficient equal to 5 and other equal to 2.
As both are prime numbers, we can not reduce this, so this is a prime polynomial.
B) 12x^4 - 18x^2 + 8x^2 - 12 = 12x^4 -10*x^2 + 124
Both coefficients are even, so we can reduce it to:
12x4 -10*x^2 + 124 = 2*(6x^4 -5*x^2 + 72)
So this is not prime.
C) 6x^3 + 9x^2 + 10x + 15
we have that:
6 = 3*2
9 = 3*3
10 = 2*5
15 = 3*5
a polinomial is only reducible if all the coefficients share at least one prime factor, here we can see that this is not the case, so this is a prime polinomial.
D) 12x^2 -3x + 4x + 7 = 12x^2 + x + 7
Again, here we have that one coefficient is 1, the only factor of 1 is itself, so we can not reduce this polinomial, this is prime.

write the equationof the line parallel to y=2x+3 and passing through the point (7,6)
Answer:
y= 2x +8
Step-by-step explanation:
y= 2x+3
gradient of given line = 2
(coefficient of x term when the coefficient of y is 1)
Parallel lines have the same gradient.
Hence gradient of the unknown line is 2.
y= 2x +c
To find the value of c, substitute a coordinate.
When x= 7, y=6,
6= 2(7) +c
6= 14 +c
c= 6-14
c= -8
Thus, the equation of the line is y= 2x +8.

Jake can read 45 pages of a book in 9 minutes. Kayleigh can read 60 pages of a book in 10 minutes. Which person reads at a faster rate per minute? A. Jake because he read at a rate of 5 pages per minute. B. Kayleigh because she read at a rate of 6 pages per minute. C. Jake because he read at a rate of 15 page per minute. D. Kayleigh because she read at a rate of 16 page per minute
Answer:
B. Kayleigh because she reads at a rate of 6 pages per minute.
Step-by-step explanation:
To find the amount of pages both people read in a minute, we can simply divide:
Jake- 45/9 = 5 pages a minute
Kayleigh- 60/10 = 6 pages a minute
Therefore, Kayleigh reads more pages a minute because 6 > 5.
