Solve the system of equations using substitution.
- 4x + 4y= 8
y= -2x – 10
-
O (4, -18)
O (12, -34)
o(-4,-2)
O (-2,-6)
Answer:
(- 4, - 2 )
Step-by-step explanation:
Given the 2 equations
- 4x + 4y = 8 → (1)
y = - 2x - 10 → (2)
Substitute y = - 2x - 10 into (1)
- 4x + 4(- 2x - 10) = 8 ← distribute and simplify left side
- 4x - 8x - 40 = 8
- 12x - 40 = 8 ( add 40 to both sides )
- 12x = 48 ( divide both sides by - 12 )
x = - 4
Substitute x = - 4 into (2) for corresponding value of y
y = - 2(- 4) - 10 = 8 - 10 = - 2
Solution is (- 4, - 2 )
yo please help i have no idea how to do this(the first 2 questions the tecaher did)
Answer:
Step-by-step explanation:
You'll need to learn the formula for the circumference of a circle. If the radius is r, the circumference C is C = 2πr. It appears that your teacher is using pi for the exact circumference and 3.14 for the approximate circumference.
The radius of the first circle is 5 in. Thus, the exact circumference is
C = 2πr = 2π(5 in) = 10π in, and the approximate circumference is
C = 2(3.14)(5 in) = 31.4 in
Multiply: (3x + 2)(4x + 2)
07x2 + 12 x+4
12 x2 + 14 x+4
33+4x+ 2
12 x2 + 18 x+2
Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of -36.14 degrees Celsius and a boiling point of 324.84 degrees Celsius . What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state?
Answer:
i. When the temperature is above [tex]616.712^{o}[/tex]F, it changes to gas.
ii. When the temperature is below [tex]-33.052^{o}[/tex]F, it changes to solid.
Step-by-step explanation:
Matter generally exists in either a solid, liquid or gaseous form. With each phase having a certain range of temperature.
Temperature scale of a given substance can be either in Celsius, Fahrenheit or Kelvin. And conversion from one scale to another can be achieved. Example, Celsius scale can be converted to Fahrenheit by:
F = [tex]\frac{9}{5}[/tex] θ + 32
where: F is the equivalent temperature in Fahrenheit, θ is the value of temperature in degree Celsius.
Given that: melting point of the substance = [tex]-36.14^{o}[/tex]C
⇒ F = [tex]\frac{9}{5}[/tex] x [tex]-36.14^{o}[/tex] + 32
= [tex]-33.052^{o}[/tex]F
The boiling point = [tex]324.84^{o}[/tex]C
F = [tex]\frac{9}{5}[/tex] x [tex]324.84^{o}[/tex] + 32
= [tex]616.712^{o}[/tex]F
The melting point of the substance is [tex]-33.052^{o}[/tex]F, and boiling point is [tex]616.712^{o}[/tex]F.
Therefore, the range of temperatures for which the substance is not in a liquid state are:
i. When the temperature is above [tex]616.712^{o}[/tex]F, it changes to gas.
ii. When the temperature is below [tex]-33.052^{o}[/tex]F, it changes to solid.

At the park, a statue stands on a marble base. The statue and marble base have a total height of 59.4 inches. The height of the marble base is 16.09 centimeters. Given that 1 inch is equal to 2.54 centimeters, what is the height of the statue?
Answer:
134.786 centimeters
Step-by-step explanation:
First you need to convert inches to cm by doing 59.4x2.54=150.876 then you subtract 16.09 from that. Your answer would be 134.786 centimeters

Find the interest for the given dates to the nearest cent. 6,150 dollars at 9% for 12/5 to 12/30 Please help! :)
Answer:
the interest is about 29.78.
Step-by-step explanation:
assuming It is at 9% per year,
6150*0.09*25/31/12=
553.5*0.08065/15=
553.5*0.0538=
29.7783 which is about 29.78
solve -x/3 > 5
a) x -15
c) x 15
Answer:
x must be a negative to cancel out the negative sign and must be greater than 15 unless it is supposed to equal 5 then a is correct
Step-by-step explanation:
Because 15/3 is equal to 5

Statment: Find the measure of the angle indicated by 19x+5
Options: 130
50
80
100
Answer:
100
Step-by-step explanation:
These two angles are corresponding which means they add up to 180.
so... 19x+5+(16x)=180
If you simplify...
35x+5=180
Then solve for x...
35x=175
x=5
Then take that 5 and fill it into 19x+5...
19(5)+5
95+5=100
Write equation of the circle with center c(-1, 5) and radius 3
Answer:
(x+1)^2 + (y-5)^2 = 9
Step-by-step explanation:
center = (h, k)
(x-h)^2 + (y-k)^2 = r^2
(x-(-1))^2 + (y-5)^2 = (3)^2
(x+1)^2 + (y-5)^2 = 9

Solve for x. Show your work: x + 3 = 12
Answer:
x=9
Step-by-step explanation:
The objective is to get x by itself, so to do that we need to subtract three from both sides:
x + 3 = 12
-3 -3
12-3= 9.
So, x=9.
Hope this helped!
Answer: x=9
x+3=12
1x+3=12
-3
=9
1x =9 ---> 1x/1 9/1
/1 /1 ---> 1x/1 9/1
x=9

solve each of these equations.
2(x+5)=3x+1
Answer:
x = 9
Step-by-step explanation:
2(x + 5) = 3x + 1
open the parenthesis
2x + 10 = 3x + 1
subtract 2x from both sides of the equation
2x - 2x + 10 = 3x - 2x + 1
10 = x + 1
subtract 1 from both sides of the equation
9 = x
Answer:
Step-by-step explanation:
Substitute
2x+10=3x+1
Subtract 3x to other side
-x+10=1
Subtract 10
-x=-9
divide -1 both sides
x= 9
