Answer:
Infinitely many solutions (the lines are identical)
Step-by-step explanation:
Let's start by getting each equation into slope intercept form (y=mx+b)
-14x-14y=28
-14x-28=14y
-x-2=y
and
7x+7y= -14
7x+14= -7y
-x-2=y
We can see that these two lines are identical which means that there are an infinite amount of answers

Find the area for the given circle. Round to the nearest tenth.
113.0 ft^2
124.8 ft^2
37.7 ft^2
452.2 ft^2
Answer:
The answer is 113.0 ft^2
Step-by-step explanation:
To find the area you do pi times the radius squared, so that would be pi times 36. which equals 113.0 ft^2.
The area of a given circle is 113.0 square feet. Therefore, option A is the correct answer.
What is area of a circle?The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.
Given that, the diameter of circle is 12 feet.
Here, radius = 12/2
= 6 feet
Now, area of a circle = 3.14×6²
= 3.14×36
= 113.0 square feet
Therefore, option A is the correct answer.

The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)
Answer:
The chance will be the same (4/7)
Step-by-step explanation:
Old bag
p(blue)=4/7
New bag
p(blue)=8/14=4/7
The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.

Write in Slope Intercept form
Answer:
its the first choice
Step-by-step explanation:
Answer:
y= -3/5x +5
Step-by-step explanation:
Step one - find where the line is intercepting. In your case this is at positive 1.
Next step is to check the change of the slope - directio. The line goes up to the positive Y access and to the left of the negative X access.
That leads to a negative slope.
Respectavley the only posible answer on this question is
y= -3/5x +5
Good luck.

Solve Using Substitution
-9x + 6y = 18
y = -6
Answer:
the answer should be x = -6
Step-by-step explanation:
-9x + 6y = 18
-9x + 6(-6) = 18
-9x - 36 = 18
-9x - 36 + 36 = 18 + 36
-9x = 54
-9x ÷ -9 = 54 ÷ -9
x = -6

What does it mean for a point to be a solution to a linear equation?
For example, if I say, "(2,5) is a solution to the equation (y=2x+3)," how could you check my claim?
Answer:
In your equation y=2x+3 and you used 2 [from your point (2,5) ] as the value of x, then y=2(2)+3=7.
now if you plotted this, that point would be (2,7), not (2,5).
So (2,5) is not the solution.
(2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].
Let be linear equation [tex]y = 2\cdot x + 3[/tex], if we know that [tex](x,y) = (2, 5)[/tex] and we need to check is [tex]2\cdot x + 3 = 5[/tex] by algebraic means, that is, we solve for [tex]x[/tex]:
[tex]2\cdot x + 3 = 5[/tex]
[tex]2\cdot x = 2[/tex]
[tex]x = 1[/tex]
Hence, we conclude that (2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].

An athlete eats 55 grams of protein per day while training. How much is this in milligrams?
Answer:
55,000 milligrams
Step-by-step explanation:
........
Answer:
55,000 milligrams (mg) is equal to 55 grams (g)
Step-by-step explanation:
(55 g/1 )* (1000 mg/1 g)
Multiply the top to get 55,000 and the bottom to get 1.
55,000/1
The gram units cancel out, leaving you with milligrams.
55,000 mg

OB. It is the graph of f(x) translated 3 units down.
OC.
It is the graph of fx) translated 3 units up.
OD. It is the graph of f(x) where the slope is decreased by 3.
Answer:
It is the graph of f(x) translated 3 units down.
Step-by-step explanation:
The graph of r(x) = x was translated 3 units down to form g(x) = r(x) - 3.

Solve 3[-x + (2 x + 1)] = x-1.
X=
DONE
Answer:
x=−2
Step-by-step explanation:
Simplify both sides of the equation.
3(−x+2x+1)=x−1
Distribute
(3)(−x)+(3)(2x)+(3)(1)=x+−1
−3x+6x+3=x+−1
Combine Like Terms
(−3x+6x)+(3)=x−1
3x+3=x−1
3x+3=x−1
Subtract x from both sides.
3x+3−x=x−1−x
2x+3=−1
Subtract 3 from both sides.
2x+3−3=−1−3
2x=−4
Divide both sides by 2.
2x/2=−4/2

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?
Answer:
200 litres
Step-by-step explanation:
let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is
g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation
To find k use g = 25, d = 100 and s = 100, then
25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )
0.025 = k
g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation
When d = 1000 and s = 64, then
g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200
F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?
Answer:
f(-2) = 0
Step-by-step explanation:
Given that:
f(x) = bx^2 + 32
f(2) = b(2)^2 + 32
f(2) = 4b + 32
f(2) = 4b = -32
f(2) = b = -32/4
f(2) = b = -8
Thus;
f(-2) = -8(-2)^2 + 32
f(-2) = -8(4) + 32
f(-2) = -32 + 32
f(-2) = 0
