Determine the solution by using substitution. Write your answer as a point below (x,y).
Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
Answer:
(2,-2)
Step-by-step explanation:
4x-10=-3x+4

4x=-3x+14

you have five $1 bills, four $5 bills, six $10 bills, and three $20 bills you select a bill at random, without replacing the bill what is the probability of a 1 then a ten?
a.11/35
b.5/51
c.5/54
d.193/306
Answer:
Option B.
Step-by-step explanation:
It is given that,
Number of $1 bills = 5
Number of $5 bills = 4
Number of $10 bills = 6
Number of $20 bills = 3
So,
Total number of bills = 5 + 4 + 6 + 3 = 18
We need to find the probability of a 1 then a ten (without replacement).
Probability of selecting $1 bill in first draw [tex]=\dfrac{5}{18}[/tex]
After one draw, the number of remaining bills is 18 - 1 = 17.
Probability of selecting $10 bill in second draw [tex]=\dfrac{6}{17}[/tex]
The probability of a 1 then a ten is
[tex]P=\dfrac{5}{18}\times \dfrac{6}{17}=\dfrac{5}{51}[/tex]
Therefore, the correct option is B.
draw the image of quadrilateral ABCD under a translation by 2 units to the right and 5 units down
To draw the image of a quadrilateral under a translation, shift every point of the quadrilateral accordingly. The translated points form the new quadrilateral.
Explanation:To draw the image of quadrilateral ABCD under a translation by 2 units to the right and 5 units down, you need to shift every point of the quadrilateral 2 units to the right and 5 units downwards. For example, if point A was at (2,3), its new point after the translation would be at (2+2, 3-5) = (4,-2). You will need to do the same for points B, C, and D. Once you have the new coordinates for A, B, C, and D, simply connect them in the same order to get your translated quadrilateral. Remember that the shape and size of the quadrilateral will not change during the translation, only its position on the graph.

Find measure of angle 2
Answer:
I am thinking 108 please correct me if I am wrong
Answer: measure angle 2 is 72
Step-by-step explanation: All angles of a triangle add up to 180 so you add 42 and 30 to find measure angle 1 which would be 108 now a horizontal line is 180 is you subtract 108 from 180 and you get 72.
Find the radius of circle if AB = 24 and OC = 5
Answer:
13
Step-by-step explanation:
Since OCB forms a right triangle, you can find the length of side OB and therefore the radius by simply using the pythagorean theorem. The first step is to note that, since AB=24 and OC bisects that, that both CB and AC have length 12. Therefore, the radius is [tex]BO=\sqrt{12^2+5^2}=13[/tex]. Hope this helps!
Find the circumference of a circle with diameter = 30 ft
Answer: 94.2
Step-by-step explanation: If pie were to equal 3.14 then you would multiply 30 and 3.14 and that would equal your answer
Answer:
94.26
Step-by-step explanation:
General formula for the circmference of a circle=2πr
π=3.142
Diameter is given in the question so to determine the radius
Radius=diameter/2
Radius=30/2
Radius=15
Circumference=2πr
=2×3.142×15
=94.26
So the final answer is 94.26
find the diameter and radius of a circle with and 18 inch circumference
Step-by-step explanation:
[tex]2 \times \pi \: \times r = 18 \\ \frac{2\pi \: r}{2\pi} = \frac{18}{2\pi} \\ r adius= 2.86in \\ diameter = 5.72in[/tex]
Answer: radius= 2.866
Diameter = 5.732
Step-by-step explanation:
Circumference of a circle is 2pir
Circumference = 2pir
Circumference =18inch
18=2pir
Pi= 3.14
18= 2×3.14×r
R= 18/2×3.14
R= 2.866
R= ~3inches
Diameter = 2radii
Diameter= 2×radius
Diameter = 2×2.866
Diameter = 5.732
Diameter = ~6

Step-by-step explanation:
The lines are parallel (they have the same slope) but have different y intercepts, so they will never intersect. The solutions are found where the lines intersect, so there are no solutions
Find the area of a circle with a circumference of 50.24 units
Answer:
A = 200.96 units^2
Step-by-step explanation:
We know the circumference is given by
C = 2 * pi *r
Approximating pi by 3.14
50.24 = 2 * 3.14 *r
50.24 = 6.28 r
Divide each side by 6.28
50.24/ 6.28 = 6.28r/6.28
8 =r
Now we can find the area
A = pi * r^2
A = 3.14 * r^2
A = 3.14 (8)^2
A = 200.96 units^2

So the answer is of option D.
When two lines intersect outside a circle to form angle D, the general formula for the measure of angle D is
angle D= 1/2(mx-my). where x and y are intercepted arcs. This formula can be used when two secants form angle D. Describe
two other situations to which this formula can apply.
Answer:
The three situations that the formula can be applied to include two secants intersecting the circle, a secant and a tangent intersecting the circle, and two tangents intersecting the circle. All three types of situations contain two lines intersecting to form an angle, as well as two intercepted arcs.

The area of a square is 81 Square
units. Find the length of a side.
Answer:
9 units
Step-by-step explanation:
To find the length of a side of a square, you need to square root the area
√81 = 9
Final answer:
The length of a side of a square with an area of 81 square units is found by taking the square root of the area, which is 9 units.
Explanation:
To find the length of a side of a square whose area is 81 square units, we use the formula for the area of a square, which is side length squared ([tex]s^2[/tex]). To solve for the side length, we take the square root of the area.
The area in this case is 81 square units, so the side length 's' will be:
√81 = 9 units
Therefore, the length of a side of the square is 9 units.

The angle of elevation of a ladder leaning against a wall is 70°. The base of the
ladder is 1.4 meters from the base of the wall. Find the length of the ladder to the
nearest tenth of a meter. *
Answer:
Refer to the explanation!
Step-by-step explanation:
We know the the angle where the ladder touches the wall at the top is a 70 degree angle, which must mean that the ladder touching the floor would be a 20 degree angle. This would be OPPOSITE / ADJACENT or TANGENT (TAN).
The TAN(20) = 2.2, when 2.2 is multiplied by the height of the ladder (1.4), you get 3.08 but rounding to the nearest tenth of a meter gives you 3.1m as the length of the ladder.
Answer: 3.1m
The length of the ladder is 4.1 meters.
The ladder and the wall forms a right-angled triangle. The ladder is represented with the hypotenuse of the triangle. The distance of the ladder from the wall is the base of the triangle.
In order to determine the length of the ladder, the acronym SOCAHTOA would be examined. We are to determine the hypotenuse given the adjacent side. So cos would be used.
Cos 70 = adjacent / hypotenuse
cos 70 = 1.4 / h
0.3420 = 1.4/h
h = 1.4 / 0.3420
h = 4.1 meters

What shape has 5 vertices and 3 sides
Answer:
a polygon
Step-by-step explanation:
A quadrilateral is a polygon. The shape that has more than 3 sides and less than 5 vertices is a quadrilateral.
What is a quadrilateral?A quadrilateral is a polygon with 4 number of sides and 4 vertices. A few examples of a quadrilateral are square, rectangle, rhombus, parallelogram, etc.
The complete question is: What shape has only straight sides more than 3 sides and has fewer than 5 vertices and can be cut into fourths?
Since we need to cut the shape into four equal parts, Also the number of sides should be greater than 3, while the number of vertices should be less than 5. Therefore, the shape that fits these criteria is a quadrilateral. For example, square, rectangle, etc.
