\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} −x+4y=−9 y=−2x+6 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
Answers
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation

Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.
What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.
Answers
Answer:
That is a 30 60 90 triangle.
In such a triangle the "middle" size = short side * sq root (3)
height = 5 * sq root (3) = 8.6602540378
Area = (1/2) * 5 * 8.6602540378
Area = 2.5 * 8.6602540378
Area = 21.6506350946 square centimeters

A=24√3
Put In Decimal Form:41.5692193817^3
Step-by-step explanation:
4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.
A=1/2(4)(4√3)

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
Answers
Answer:
We can make the paint amount equal by making sure the parameters have the same unit
Step-by-step explanation:
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
To solve the above question, we have the conversion rate:
We can make the paint amount equal by making sure the parameters have the same unit
Hence:
1 gallon (gal) = 3.785411784 kilogram (kg).
Billy had 5 gallons of paint.
1 gallon (gal) = 3.785411784 kilogram (kg).
5 gallons of paint = x
Cross Multiply
x = 5 × 3.785411784 kg
18.92705892 kilograms of paint
Approximately 18.93 Kilograms of paint
Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

Answers
Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3

Answer:
15.08 m
Step-by-step explanation:
You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.
Angle XZW is 180° -108° = 72°
The circumference is C=πd, so the arc of interest is ...
XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m
XW ≈ 15.08 m
_____
If you use π = 3.14, then your answer will be 15.07 m.
