solve the system of equations -4x- y = -18 and 2x + 3y = 24 by combining the equations
Answer:
x = 3
y = 6
Step-by-step explanation:
-4x- y = -18
2x + 3y = 24 (Multiply everything by 2)
-4x - y = -18
4x + 6y = 48
5y = 30
y = 6
-4x- y = -18
-4x - 6 = -18
-4x = -12
x = 3

ayudaaa se los agradeceria
Answer:
-2
Step-by-step explanation:
since the base are the same you add the exponent.
4x+2 + 2x-1= -3x-17
4x+2x +3x =-17-2+1
9x =-18
x=-2
Write an expression that is equivalent to 6(7 x - x)
Answer:
Step-by-step explanation:
Assuming that you meant 6(7x - x), we get: 6(6x) = 36x
Solve the system by substitution.
y = 8x – 6
y = 2x
Answer:
x = 1
y = 2
Step-by-step explanation:
y =8x - 6 ---------------------------------(I)
y = 2x -------------------------------------(II)
substitute y = 2x in equation (I)
2x = 8x - 6
Add 6 to both sides
2x + 6 = 8x
Subtract 2x from both sides
6 = 8x - 2x
6 = 6x
Divide both sides by 6
6/6 = x
x = 1
Substitute x = 1 in equation (II)
y = 2*1
y = 2

Which equation has the same solution as x^2 - 8x - 15 =3
Answer:
x^2 - 6x -18 is the same so you can write
x^2 - 6x -18 = ( x^2 - 8x - 15 = 3)
Step-by-step explanation:
When we subtract 3 each side we get -18 as -15 -3 is -18
x^2 - 6x -15 = 3
x^2 - 6x -15- 3 =
x^2 - 6x - 18 = 0
When equations equal or set equal to zero we can then use the quadratic formula found in your book.
x1
= −(−8) − √ (−8)2 − 4×1×(−18) / 2×1
= 8 − 2 × √ 34
/2
≈ −1.831
x^2
= −(−8) + √ (−8)2 − 4×1×(−18)
/2×1
= 8 + 2 × √ 34 / 2
≈ 9.831

find the measure of arc VF. (look at the picture provided) please help
Answer:
60degrees
Step-by-step explanation:
Using the theorem that states that angle at the vertex is half the difference of the angles at the intercepted arcs
Angle at vertex can be gotten by taking the difference of 119 and 65
Angle at the vertex = 119 - 65
Angle at the vertex = 54
Hence;
54 = 1/2(168-VF)
Cross multiply
54 * 2 = 168-VF
108 = 168 - VF
VF = 168 - 108
VF = 60degrees
Hence the measure of arc VF is 60degrees

The first year of a charity walk event had an attendance of 500. The attendance
y increases by 5% each year.
How many people will attend in the 10th year?
A) 525 People
B) 814 People
C) 250 People
Answer:
b
Step-by-step explanation:
Number of people in the 10th year can be determined using this formula
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future number of people at the charity
P = number of people at the charity in the first year
R = rate of increase
N = number of years
500 x (1.05)^10 = 814 people

log[tex]Evaluate log _{2} {\frac{1}{128} }[/tex]
9514 1404 393
Answer:
-7
Step-by-step explanation:
It is helpful to recognize 128 = 2^7. Then you know ...
[tex]\log_2\dfrac{1}{128}=\log_2{2^{-7}} =\boxed{-7}[/tex]
__
If you don't know that, you can use the change of base formula:
[tex]\log_2{\dfrac{1}{128}}=\dfrac{\log{\dfrac{1}{128}}}{\log{2}}=\dfrac{-2.1072}{0.30103}=\boxed{-7}[/tex]
