How many solutions does this system have?
6x+3y=-12
y=-2x+4
one
two
an infinite number
no solution
Answers
Answer:
no solution
Step-by-step explanation:
when you substitute \(y\) for \(-2x+4\) the equation is false
how I solved this:
1. substitute \(y\) for \(-2x+4\)
\(6x+3(-2x+4)=-12\)
2. distribute the 3
\(6x+-6x+12=-12\)
3. combine like terms
\(12=-12\)
this is incorrect because 12 does not equal -12, so there is no solution

Answer: The perimeter of crater lake is 17.27 miles.
Step-by-step explanation:
The shape of the lake is like a circle
The diameter of lake = d = 5.5 miles
∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles
Let The perimeter of crater lake = p miles
Now, As we know
The perimeter of circle = \pi × diameter
the value of \pi = 3.14
Or, p = pi × d
Or, p = pi × 5.5 miles
Or, p = 3.14 × 5.5 miles
∴ p = 17.27 miles
So, The perimeter of circle = perimeter of lake = p = 17.27 miles
Hence, The perimeter of the crater lake is 17.27 miles.

The answers of all four questions are below.
Step-by-step explanation:
(5)4+2x=−2x+44
Step 1: Simplify both sides of the equation.
2x+4=−2x+44
Step 2: Add 2x to both sides.
2x+4+2x=−2x+44+2x
4x+4=44
Step 3: Subtract 4 from both sides.
4x+4−4=44−4
4x=40
Step 4: Divide both sides by 4.
4x/4=40/4
x=10
-----------------------------------------------------------------------------------------------------------------
(6)114−3x=194−11x
Step 1: Simplify both sides of the equation.
114−3x=194−11x
114+−3x=194+−11x
−3x+114=−11x+194
Step 2: Add 11x to both sides.
−3x+114+11x=−11x+194+11x
8x+114=194
Step 3: Subtract 114 from both sides.
8x+114−114=194−114
8x=80
Step 4: Divide both sides by 8.
8x/8 = 80/8
x=10
------------------------------------------------------------------------------------------------------
(7)4x-12=-2x+36
4x-12+12=-2x+36+12

4x+2x=-2x+48+2x
6x=48
6x/6=48/6
x=8

(9)-3x+90=117-12x
-3x+90-90=117-12x-90

Answer:

Step-by-step explanation:
Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.
a. PossibilitiesAs the tree diagram shows, the number of possible meals is ...
(possible meats)×(possible fruits)×(possible desserts)
= 3×2×2 = 12
There are 12 possible lunch options.
b. CookiesHalf the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:
P(no cookie) = 1/2

Additional comment
The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

2\(\pi\)1 = 6.282\(\pi\)2 = 12.59So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).
12.59 - 6.28 = 6.31According to the above, the difference of the circumferences would be 6.31 cm.
How to calculate the area of the circle?To calculate the area of the circle we must apply the following formula.

He decides to calculate the surface area of the building in order to estimate how much water he will need. He does the calculation using the standard formula and, after doing the job, realizes he overestimated the amount of water he needed. Where was his mistake? a.) He forgot that there is no formula for the surface area of a cube. b.) He forgot to add the area of the base to the total surface are of the cube. c.) He forgot to square the result. d.) He forgot to subtract the area of the base from the total surface area of the cube.

Answer:
D. He forgot to subtract the area of the base from the total surface area of the cube.

This assignment is due soon! If someone can help it would be great. It is about triangle angle sun theorem.
Answers
Ok so basically we know that all the angles in a triangle add up to 180 degrees.
That means
(x-7) + (2x) + (x+11) = 180 because we combined all the angle measures.
To solve this equation we've got to combine like terms.
We can combine the x's together so we have 4x + (-7) + 11 =180.
Then we can combine -7 and 11 to get 4 because 11-7=4.
Now our equation is 4x+4=180.
We can subtract 4 from both sides of the equation to get 4x=176.
Then simplify this by doing 176/4=44.
That means x=44.

What is the solution to this equation?
х/-5= 15
A. X = 3
B. X= -3
C. X= 75
D. x= -75
Answers
Answer:
\(D\)
Step-by-step explanation:
\(\frac{x}{-5} =15\)
\(\frac{x}{-5}(-5) =15(-5)\)
\(x=-75\)
Answer: x = 75
Explanation: In this problem, notice that x is being divided by -5 so to get x by itself, we need to multiply both sides of the equation by -5.
Notice that on the left side, the -5 and -5 cancel
each other out so we're just left with x.
On the right side, we have (-15)(-5) which is 75.
So x = 75.
Finally, remember that we can check our answer by
plugging a 75 back into the original equation.
This is shown in red below.

Answers
Using the point-slope form: y - y₁ = m(x - x₁)
Plug in the values: y - 3 = -2(x - (-1))
Simplify: y - 3 = -2(x + 1)
Now, we can find the y value of the point:
y - 3 = -2(-1 + 1)
y - 3 = 0
y = 3
So, the y value of the point is 3.
