Answer:

y=2x-3

Step-by-step explanation:

The slope-intercept form of the original equation would be y=3/8−x/2

Therefore, the slope of the perpendicular line would be m=2

Then, the y-intercept would be 7=(2)x(5)+a

A=-3

Answer:

y=2x+3

Which is the solution set of the compound inequality 3.5 x minus 10 greater-than negative 3 and 8 x minus 9 less-than 39

dexar [7]

The solution for the compound inequality is $x \in(2,6)$

Explanation:

The equations are $3.5x-10>-3$ and $8x-9$

To find the solution set for these compound inequalities, we need to solve the inequality.

First, we shall solve the inequality $3.5x-10>-3$

Adding both sides of the equation by 10, we have,

$3.5x>7$

Dividing both sides by 3.5, we get,

$x>2$

Now, we shall solve the inequality $8x-9$ ,

Adding both sides of the equation by 9, we have,

$8x$

Dividing both sides by 8, we get,

$x$

Thus, the solution set for the inequalities $3.5x-10>-3$ and $8x-9$ is $x \in(2,6)$

Mr. Hudkins wants his 6th grade math class to memorize their multiplication facts. He decides to increase the number of facts th

Maksim231197 [3]

Answer: m = 15w

Step-by-step explanation: The reason why the answer is m = 15w is because since he said "He decides to increase the number of facts they are expected to memorize each week." Which makes it so that only the multiplication fact increased to 15 since they wouldn't put it lower then that. And there is a 2nd reason why the multiplication fact is 15. the reason why is because theres only one answer with 30 and its completely wrong. So therefore,, The answer is Multiplication Fact = 15weeks.

¿Cuáles son los procedimientos a ambos lados de la igualdad que se deben realizar para calcular el valor de la incógnita x en la

PilotLPTM [1.2K]

Answer:

Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:

El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.
El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.

Step-by-step explanation:

Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:

2x + 5 = 7

Seguimos el primer paso: el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual:

2x = 7 - 5

Seguimos el segundo paso: el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:

$x=\frac{7-5}{2}$

Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:

$x=\frac{2}{2}$
$x=1$

El resultado que nos daría la incógnita x sería 1. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:

2x + 5 = 7
2 *(1) + 5 = 7
2 + 5 = 7
7 = 7

Así, identificamos que los procesos realizados fueron correctos.

If the exchange rate is €1.20 to £1, how many pounds sterling would you get for €180?

Len [333]

Answer:

150 pounds

Step-by-step explanation:

1.20 euros = 1 pound

180 euros = x pounds

Set up the proportion

1.20 Euros/1 pound = 180 Euros / x pound Cross multiply

1.20*x = 1 * 180 Combine

1.20 x = 180 Divide by 1.2

x = 180 / 1.20

x = 150 pounds.

As a bonus, you might want to try and guess which is the stronger currency.
