Answer:
(2,0)
Step-by-step explanation:
2x-y=4
Substitute x with 2, and y with 0.
2(2)-0=4
2 multiplied to 2 is 4, then subtracted to 0 would be 4, thus it is correct.
3x-y=6
Substitute x with 2, and y with 0.
3(2)-0=6
3 multiplied to 2 is 6, then 6 subtracted with 0 is 6, thus it is correct.

The required length of AC is 8 unit.
What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees.
Given that,
In triangle ABC, angle C is a right angle,
Also side AB = 17, BC = 15 and AC =?
To find side AC, use Pythagoreans theorem,
AB² = BC² + AC²
Substitute the values of AB and BC,
17² = 15² + AC²
289 = 225 + AC²
⇒AC² = 289 - 225
⇒AC² = 64
⇒AC = 8
The required length of AC is 8 unit.

what is the base if the height is 6ft and the area is 14 ft on a triangle
Answer:
b = 4.66666667
Step-by-step explanation:
The equation for finding the area of a triangle is
0.5b x h = a
b = base
h = height
a = area
So I calculated 14 divided by 6
And got 2.3333333
And since that number is half of the base, I multiplied it by 2
2.333 x 2 ≈ 4.66666667
Nayeli wants to earn some extra money so she sells lemonade for $2 per cup and orange juice for $3 per cup. She sells a total of 100 cups and earns $240. Later she wants to find the number of cups of lemonade and the number of cups of orange juice she sold. Which system of equations below represents this situation?
1. 2x + 3y = 240 AND x + y = 100
2. 2x + 3y = 100 AND x + y = 240
3. x + 2y = 100 AND 3x + y = 240
4. 2x + 100 = 240.AND x = 3y
Answer:
1
Step-by-step explanation:
let x represent lemonade and y represent orange juice
the total earning is $240. 2x+3y=240 allows you to find the number of each cup you need to sell to get $240.
the total number of cups sold is 100. x+y=100 gives you the other equation necessary to find the number of cups of each sold if you told a total of 100

How much more paper is used for the label of the large can of tomato paste than for the label of the small can?
Answer:
23.57
Step-by-step explanation:
small can surface area - 25.13
big can surface area - 56.55
small can paper - (25.13-6.28) = 18.85
big can paper - (56.55-14.14) = 42.41
diffrence - 42.42 - 18.85 = 23.57

Find the measure of the exterior angle.
Answer: 108 degrees
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the two remote interior angles. (Remote referring to the farthest angles from the exterior angle) 2a = (a+10) + 44. Combine like terms.
2a = a+ 54. Subtract “a” from both sides.
a= 54
You can check for correctness by plugging in 54 for a. 2(54) = (54+ 10) + 44. 108= 108.
(Remember, the exterior angle should equal the sum of the two remote interior angles)
Two functions are graphed on the coordinate plane.
On a coordinate plane, a curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A straight horizontal line, labeled f of x, crosses the y-axis at (0, 4).
Which represents where f(x) = g(x)?
f(4) = g(4) and f(0) = g(0)
f(–4) = g(–4) and f(0) = g(0)
f(–4) = g(–2) and f(4) = g(4)
f(0) = g(–4) and f(4) = g(–2)
Answer:
Answer:
(B) f(-4)=g(-4) and f(0)=g(0)
Step-by-step explanation:
From the given graph, the lines f(x) and g(x) intersects at two different points.
When x=-4, f(-4)=4 and g(-4)=4
When x=0, f(0)=4 and g(0)=4
Therefore, the points which represent where f(x)=g(x) are:
f(-4)=g(-4); and
f(0)=g(0)
The correct option is B.

Answer: x=4
Step-by-step explanation:
Given
2(3x+4)-2x=24
Expand parenthesis
6x+8-2x=24
Combine like terms
4x+8=24
Subtract 8 on both sides
4x+8-8=24-8
4x=16
Divide 4 on both sides
4x/4=16/4
x=4

The area of a regular hexagon inscribed in a circle with radius 2 is . Round your answer to the nearest tenth.
Answer:
10.4 to nearest tenth.
Step-by-step explanation:
If we draw lines from the centre of the circle to each vertex of the hexagon we get 6 equilateral triangles of side length 2.
Altitude of each triangle = sqrt(2^2 - 1^2)
= sqrt3.
So the area of 1 triangle = 1/2 * 2 * sqrt3
= sqrt3
Therefore the area of the hexagon = 6 * sqrt3
= 6sqrt3
= 10.3923
Either enter an exact answer in terms of . or use 3.14 for .
Answer: 75π units³ or 235.5 units³
Step-by-step explanation: Notice that the figure shown here is a cylinder.
To find the volume of a cylinder, start with the
formula for the volume of a cylinder, which is V = πr²h.
Here, notice that our cylinder has a
radius of 5 units and a height of 3 units.
So we have (π)(5 units)²(3 units).
Start by simplifying the exponent.
(5 units)² is (5 units)(5 units) or 25 units².
So we have (π)(25 units²)(3 units).
Now, (25 units²)(3 units) is 75 units³.
So we have 75π units³.
So the volume of the cylinder shown here is 75π units³.
Remember that π is approximately equal to 22/7 or 3.14 so we
can estimate the value of the volume by plugging in 3.14 for π.
So we have (75)(3.14) which is equal to 235.5.
So the value of the volume is approximately 235.5 units³.
