Answer:

\huge \boxed{ \boxed{ \sf \: y = x + 15}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know:</h3>
  • linear equation
  • linear equation word problems
  • PEMDAS
<h3>tips and formulas:</h3>
  • linear equation:y=mx+b
<h3>let's solve:</h3>

all we need to care about the middle condition which is

<h3>the new test score is 15 points more than the original score</h3>

given that

original score is x

New score is y

if you pay attention to the given condition

we can find it same as linear equation

therefore

according to the question

the equation is

<h2>y=x+15</h2>

La ecuación de la linea es: y = -4x + 2600

<h3>¿Como determinar la relación lineal?</h3>

Tenemos dos puntos para nuestra linea, los cuales son (350, 1200) y (320, 1320).

Con esos dos puntos podemos obtener la pendiente de la linea:

a = \frac{1320 - 1200}{\ 320 - \ 350}  = -4

Entonces la linea es algo como:

y = (-4)*x + b

Para obtener el valor de b usamos uno de los dos puntos dados, como el primero:

1200 = (-4)*350 + b

1200 = -1400 + b

1200 + 1400 = b = 2600

Entonces la linea es:

y = -4x + 2600

Si se vendieron 35 unidades, podemos reemplazar:

35 = -4*x + 2600

4x = 2600 - 35 = 2565

x = 2565/4 = 641.25

Es decir, el precio es $641.25

The points (3,5) and (21,35) form a proportional relationship. Find the slope of the line through thepoints. Then use the slope
ICE Princess25 [194]

\begin{gathered} \text{ The slope of a line that passes through 2 points is } \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{35-5}{21-3} \\ m=\frac{30}{18} \\ m=\frac{5}{3} \end{gathered}

The slope is 5/3

For the graph, we have to see that (3,5) and (21,35) are in the line, , or that the equation of the line is

y=\frac{5}{3}x

In the case A), a point in the line is (3,5) so the answer is A.

The product of two consecutive integers is 420 which quadratic equation can be used to find x the lesser number
Fynjy0 [20]

Answer:

Step-by-step explanation:

If the smallest number is 'x', then the other number = x +1

x*(x+1)= 420

Use distributive property

x*x + x*1 = 420

x² + x - 420 =0   ------> this is the required quadratic equation.
