Answer:
2nd option
Step-by-step explanation:
7x - y = 7 ( multiply through by - 1 )
- 7x + y =- 7 ( add 7x to both sides )
y = 7x - 7 → (1)
7x² - y = 7 → (2)
substitute y = 7x - 7 into (2)
7x² - (7x - 7) = 7 ← distribute parenthesis on left side
7x² - 7x + 7 = 7 ( subtract 7 from both sides )
7x² - 7x = 0 ← in standard form
7x(x - 1) = 0 ← in factored form
equate each factor to zero and solve for x
7x = 0 ⇒ x = 0
x - 1 = 0 ⇒ x = 1
substitute these values into (1) for corresponding values of y
x = 0 : y = 7(0) - 7 = 0 - 7 = - 7 ⇒ (0, - 7 )
x = 1 : y = 7(1) - 7 = 7 - 7 = 0 ⇒ (1, 0 )

Rewrite the equation in exponential form, and show how you got there:
Answer: [tex]13^0=1[/tex]
Step-by-step explanation:
Logarithms are in the format [tex]log_{b} a=c[/tex] while exponential form is in the format [tex]b^c=a[/tex]
So we can transfer a,b, and c from the log form to the exponential form
[tex]log_{13} 1=0\\\\13^0=1[/tex]

Step-by-step explanation:
SA = bh + 2ls + lb
b = 6
h = 5
l = 9
s = 5.5
SA= (6 x 5) + 2(9 x 5.5) + (9 x 6)
SA = 30 + 2 x 49.5 + 54
SA = 30 + 99 + 54
SA = 183
Which values of c will cause the quadratic equation –x2 3x c = 0 to have no real number solutions? check all that apply.
The given quadratic equation will not have any real solution for c<-9/4.
The given quadratic equation is:
[tex]-x^{2} +3x+c=0[/tex]
What is a quadratic equation?Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation with a≠0.
In order to have no real solution, the discriminant of a quadratic equation will be less than zero.
[tex]D < 0[/tex]
[tex]3^{2} -4(-1)(c) < 0[/tex]
[tex]9+4c < 0[/tex]
[tex]c < -\frac{9}{4}[/tex]
For [tex]c < -\frac{9}{4}[/tex] the given quadratic equation will have no real solutions.
Hence, the given quadratic equation will not have any real solution for c<-9/4.

A certain gas has a volume of 10 liters at a temperature of 404 kelvins (k) and a pressure of 36 pascals (pa). if the temperature is raised to 450 k and the pressure is raised to 40 pa, what is its volume? to the nearest liter, the volume is liters.
The final volume of the ideal gas is 10.02 liters.
Given Initial volume V₁=10 liters
Initial temperature T₁=404K
Initial pressure P₁ = 36 pascals
Final volume = V₂
Final temperature T₂ = 450K
Final pressure P₂ =40 pascals
What is the ideal gas equation?The ideal gas equation with usual notations is given by:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
So, [tex]\frac{36*10}{404} =\frac{40*V_2}{450}[/tex]
[tex]V_2=[/tex]10.02 liters
Hence, the final volume of the ideal gas is 10.02 liters.

John has 7 mice in his lab. He knows a mouse population doubles every month. When can he expect to have 2,625 mice? Please explain.
Answer:
31 years and 3 months or non
Step-by-step explanation:
the first thought that comes into my mind is
1 month=7 mice
n month= 7×n=2625 mice
n= 2625÷7=375
so it takes him to 375 months = 31 year and 3 months
but putting on a 2nd thought, I noticed that mice and mouse is different species. so there aren't exact answer

If you look at the help image I attached, what we are given is in RED and what we solve is in BLUE.
First, draw a diagonal in the square. Its length is the diameter, but we don't know the exact value. Since two right triangles have been created, we use Pythagorean Therom to solve for the hypotenuse/diameter:
[tex]a^2+b^2=c^2\\6^2+6^2=c^2[/tex]
[tex]\sqrt{36+36} =c[/tex]
[tex]6\sqrt{2}=c[/tex]
If diameter = [tex]6\sqrt{2}[/tex], then radius is [tex]\frac{6\sqrt{2}}{2}[/tex] or [tex]3\sqrt{2}[/tex]

A bouncy ball is dropped from a height of 16ft and always rebounds of the distance of the previous fall.
What distance does it rebound the 5th time?
What is the total distance the ball has travelled after this time?
Draw a picture to represent the bouncing ball.
The bouncy ball follows a geometric sequence or pattern
The distance of rebound the 5th time is 0.015625 ftThe total distance the ball has travelled after this time is 5.328125 feetThe distance of rebound the 5th timeThe given parameters are:
Initial height, a = 16 ftRebound rate = 0.25The distance at rebound n is represented as:
Hn = a * r^n
At the 5th time, we have:
H5 = 16 * 0.25^5
Evaluate
H5 = 0.015625
Hence, the distance of rebound the 5th time is 0.015625 ft
The total distance travelledTo do this, we calculate H1 to H5
So, we have:
H1 = 16 * 0.25^1 = 4
H2 = 16 * 0.25^2 = 1
H3 = 16 * 0.25^3 = 0.25
H4 = 16 * 0.25^4 = 0.0625
H5 = 0.015625
Add this distances
Total = 4 + 1 + 0.25 + 0.0625 + 0.015625
Total = 5.328125
Hence, the total distance the ball has travelled after this time is 5.328125
