I need help ASAP , State whether set of ordered pairs represent a function
{(-13,4) , (7,-15), (-13,9) (6,-12) (-18,0)
Answer:
No, the given set of pairs does not represent a function
Step-by-step explanation:
For a set of values to be a function, each input must have one and only one output value
Now, for the given set, we can note that:
The input -13 has two output values; 4 and 9
Therefore, this set is not a function

Three bags of chips and sodas cost $12.50. Four bags of chips and two sodas cost $10.00. What is the cost of each item? ASAP pls!
Step-by-step explanation:
3c + 3s = 12.50
4c + 2s = 10.00
3S = 12.50-3c
s = 4.17 - c
4c + 2 (4.17-c) = 10.00
2c + 8.34 = 10.00
2c = 1.66
chips = 0.83
soda = 3.34

make an equation: 110=(8x+30)
simplify and solve
x=10
Solve for x in the diagram below.
3x
100°
2
Answer:
20 degrees
Step-by-step explanation:
The line has a total of 180 degrees. So, x+100+3x=180. Then, we subtract 100 from both sides to get x+3x=80. Then, x+3x=4x. So, 4x=80 degrees, and so divide by 4 on both sides and you get x=20 degrees.
Gina started with the circle (x−2)2+y2=16. She translated it 4 units left and 1 unit down. Then she reduced the radius by 1 unit. What is the equation of her new circle?
Answer:
(x + 2)² + (y + 1)² = 9
Step-by-step explanation:
Gina started with a circle with the given equation as,
(x - 2)² + (y - 0)² = 16
Since, standard equation of a circle is,
(x - a)² + (y - b)² = r²
Here (a, b) is the center of the circle and 'r' is the radius.
Therefore, from the given equation of the circle,
Center of the circle → (2, 0)
Radius of the circle → √16 = 4 units
She translated this circle 4 units left and 1 unit down.
Rule for the new center after translation will be,
(x, y) → (x - 4, y - 1)
(2, 0) → (2 - 4, 0 - 1)
→ (-2, -1)
Coordinates of the new center → (-2, -1)
Then she reduced the radius by 1 units.
Therefore, radius of the new circle = 4 - 1 = 3 units
Now we substitute these values in the standard equation of the circle to get the equation of the new circle.
(x + 2)² + (y + 1)² = 3²
(x + 2)² + (y + 1)² = 9

What is angle?Angle is a geometrical figure that is formed when two lines intersect. It is measured in degrees or radians and is represented by the symbol θ (theta). Angles are used in trigonometry, geometry, physics, engineering, and other fields. An angle can be acute, right, obtuse, straight, or reflex. Acute angles measure less than 90°, right angles measure 90°, obtuse angles measure greater than 90°, straight angles measure 180°, and reflex angles measure greater than 180°.
The measure of ZK is 47.00 degrees. This can be determined by calculating the interior angles of the triangle. According to the Triangle Angle Sum Theorem, the sum of the interior angles of any triangle is 180 degrees. Therefore, in the triangle AJKL, the three interior angles must sum to 180 degrees.
Since two of the angles, AJK and AKL, are equal, we can calculate the measure of ZK as follows:
AJK + AKL + ZK = 180
15 + 15 + ZK = 180
30 + ZK = 180
ZK = 180 − 30
ZK = 150
Since the measure of the angle must be given to the nearest tenth of a degree, we can round up to get the final answer:
ZK = 150 ≈ 150.0 ≈ 150.00 ≈ 47.00
Therefore, the measure of ZK is 47.00 degrees.

Firas and Nabil are comparing their bank accounts. "I have four times more money than
you" , Firas says. "Anyway, I have only $240 less than you" , Nabil answers .
How much money does each one of them have in his account ?
should be solved as a system
Answer:
Firas = $320
Nabil = $80
Step-by-step explanation:
Firas = 4x
Nabil = x
x + 240 = 4x
3x = 240
x = $80
Firas = $240 + $80 OR $80 x 3 = $320
Nabil = $80

Find the measures of the numbered angles in rhombus ABCD.
Answer:
∠1 = 66°
∠2 = 24°
∠3 = 24°
∠4 = 90°
Step-by-step explanation:
∠1 = 90 - 24 = 66°
∠2 = 24°
∠3 = 24° because segment DB bisects ∠ABC
∠4 = 90° because it is a right angle
