For what values of a is the value of the binomial 2a−1 smaller than the value of the binomial 7−1.2a by 7?

Nimfa-mama [501]

ANSWER

$a = \frac{5}{16}$

EXPLANATION

We want to find the value of a for which the binomial, 2a-1 is smaller than the value of the binomial 7-1.2a by 7.

This means that, when we subtract 2a-1 from 7-1.2a, we should get 7.

$7 - 1.2a - (2a - 1) = 7$

Expand:

$7 - 1.2a - 2a + 1= 7$

Group similar terms:

$- 1.2a - 2a = 7 - 7 - 1$

$- 3.2a = - 1$

Divide both sides by -3.2,

$a = \frac{ - 1}{ - 3.2}$

$a = \frac{5}{16}$

Answer:

Step-by-step explanation:

You want to know the value of x that makes y=1000. You can plug the equation in to your calculator or desmos. Look at the table for when y=1000. X is 26.

To check, plug in 26 for x. 26^2 + 20(26) - 196 = 1000.

Find the distance between the points ( – 9, – 4) and ( – 4,8).

Dmitriy789 [7]

Answer:

$Distance=13\ units$

Step-by-step explanation:

Distance between two points: Distance between two pints $(x_1,y_1)\ and\ (x_2,y_2)$ is given by

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between $(-9,-4)\ and\ (-4,8).$

$d=\sqrt{(-4-(-9))^2+(8-(-4))^2}\\\\d=\sqrt{(-4+9)^2+(8+4)^2}\\\\d=\sqrt{(5)^2+(12)^2}=\sqrt{25+144}\\\\d=\sqrt{169}\\\\d=13$
