Answer:
Step-by-step explanation:
Let the 2 consecutive integers be x and x+1.
x²+(x+1)²=1684
x²+(x+1)(x+1)=1684
x²+x²+x+x+1=1684
2x²+2x-1683=0

If the cost of making 20 copies is $1.30, how much will 1 copy cost?
Answer:
6,5
Step-by-step explanation:
1 dollar 30 cent = 130 cent
20 copies=130
1 copy=130/20=6,5
The cost of the copy per unit will be $0.065 for each copy.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
If the cost of making 20 copies is $1.30.
Then the cost of each copy is given by the division of $1.30 and 20. Then we rate is given as,
Rate = $1.30 / 20
Rate = $0.065 for each copy
The cost of the copy per unit will be $0.065 for each copy.
More about the rate link is given below.

B. Noah writes the equation 3 (x+7)=57 to represent the situation. DO YOU agree with him? Explain your answer.
Answer:
Yes , i agree with Noah that the equation would be 3(x + 7) = 57
Step-by-step explanation:
P.S - The exact question is -
To find - Noah writes the equation 3 (x+7)=57 to represent the situation.
DO YOU agree with him? Explain your answer.
Proof -
Yes , i agree with Noah
Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .
Because 57 is divided into x 7 x 7 x 7
∴ we can write it as
3 times x + 3 times 7 = 57
⇒3(x) + 3(7) = 57
⇒3(x+7) = 57
Ans Noah give the same equation 3 (x+7)=57
So, I agree with Noah.

si para lavar un inodoro de 6 litros de capacidad, se utilizan 20 litros de agua.¿Como representarías el consumo total de de agua(descargas elevado)del inodoro, asumiendo que es lavado solamente en una ocasión?
Responder:
26 litros
Explicación paso a paso:
Dado lo siguiente
Litros totales de agua utilizados = 20 litros
El inodoro en sí contiene 6 litros de agua.
Agua total consumida = litro de agua utilizada + agua contenida en el inodoro
Agua total consumida = 20 litros + 6 litros
Agua total consumida = 26 litros
Por lo tanto, el consumo total de agua del inodoro, asumiendo que se descarga una sola vez, es de 26 litros

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of people 13 took the trip. She was able to purchase coach tickets for $390 and first class tickets for $1000. She used her total budget for airfare for the trip, which was $8120. How many first class tickets did she buy? How many coach tickets did she buy?
Answer:
x = 6
Step-by-step explanation:
Coach ticket = $180
first class ticket = $1020
people = 8
Let x be number of coach tickets
Then number of first class tickets = (8 - x)
x * 180 + (8 - x) * 1020 = 3120
180 X + 8 * 1020 - 1020 x = 3120
180 x + 8160 - 1020 x = 3120
180 x - 1020 x = 3120 -8160
- 840 x = - 5040
840 x = 5040
x = 6
So 6 coach class tickets and 2 first class tickets
Answer:
She bought 8 coach tickets
And 5 first class tickets
Step-by-step explanation:
390 x 8 = 3,120
1000 x 5 = 5,000
3,120 + 5,000 = 8,120

Use the quadratic equation y = –2x^2 + 4x +5 to complete the statements.
Answer:
Step-by-step explanation:
Given quadratic equation is,
y = -2x² + 4x + 5
y = -2(x² - 2x) + 5
y = -2(x² - 2x + 1 - 1) + 5
y = -2(x² - 2x + 1) + 2 + 5
y = -2(x - 1)² + 7
This equation is in the vertex form of the quadratic equation,
y = a(x - h)² + k
where, (h, k) is the vertex of the parabola.
Therefore, vertex of the given quadratic equation is (1, 7)
The equation can be rewritten as y = -2(x - 1)² + 7.
Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).
