Answer: x = 5/7

Step-by-step explanation:

11x - 8 + 4x - 3

Get x to 1 side

7x - 8 = -3

Add 8 to both sides to cancel out 8

7x = 5

divide by 7

x= 5/7

Xavier and Ava are employees for a company. Xavier is making a salary of $42,700.

MrMuchimi

$62,342 is the salary earned by Ava.

Step-by-step explanation:

step 1 :

Xavier's salary = $42,700

step 2 :

Ava's salary = 46% higher than Xavier salary.

= 100% of Xavier salary + 46% of Xavier salary

= 146% of Xavier salary

step 3 :

Ava is earning a salary = (146/100) $\times$ 42,700

= 146 $\times$ 427

= 62,342

∴ Ava is earning a salary of $62,342.

Find the angle between u = (-2,-5) and v = (5,2)

OleMash [197]

The angle between u = (-2,-5) and v = (5,2) is 134 degrees approximately.

Solution:

Given, two vectors are u = (-2, -5) and v = (5, 2)

We have to find the angle between two vectors.

We know that,

$a. b=\|a\| .\|b\| \times \cos \theta$

where $\theta$ is angle between vectors a and b

$\text { Now vectors are }(-2 \vec{\imath}-5 \vec{\jmath}) \text { and }(5 \vec{\imath}+2 \vec{\jmath})$

$(-2 \vec{\imath}-5 \vec{\jmath}) \cdot(5 \vec{\imath}+2 \vec{\jmath})=\sqrt{(-2)^{2}+(-5)^{2}} \times \sqrt{5^{2}+2^{2}} \times \cos \theta$

$\text { since }\|a\|=\sqrt{x^{2}+y^{2}} \text { for } a=x \vec{\imath}+y \vec{\jmath}$

$\begin{array}{l}{-10-10=\sqrt{29} \times \sqrt{29} \times \cos \theta} \\\\ {-20=29 \times \cos \theta} \\\\ {\cos \theta=\frac{-20}{29}} \\\\ {\theta=\cos ^{-1} \frac{-20}{29}} \\\\ {\theta=133.60}\end{array}$

Hence, the angle between given two vectors is 134 degrees approximately.
