What is the solution of this system of linear equations? 3y = x + 6 y – x = 3

Naya [18.7K]

3y = x + 6
y – x = 3 -----------> x=y - 3 (substitute in 1st equation)

3y = y - 3 +6
3y - y = 3
2y = 3
y = 2/3

x= y - 3 = 2/3 -3 = 2/3 - 9/3 = - 7/3

x= - 7/3, y = 2/3

Solve for e. 9e+4=-5e+14+13e9e+4=−5e+14+13e e=

Kitty [74]

Answer:

e = 10

Step-by-step explanation:

9e+4=-5e+14+13e

Combine like terms

9e+4=14+8e

Subtract 8e from both sides

9e-8e+4=8e-8e +14

e +4 = 14

Subtract 4 from each side

e+4-4 = 14-4

e = 10

Use synthetic division to find P (-10) for P(x)=2x^3+14x^2-58x

Savatey [412]

The polynomial remainder theorem states that the remainder upon dividing a polynomial $p(x)$ by $x-c$ is the same as the value of $p(c)$ , so to find $p(-10)$ you need to find the remainder upon dividing

$\dfrac{2x^3+14x^2-58x}{x+10}$

You have

..... | 2 ... 14 ... -58
-10 | ... -20 ... 60
--------------------------
..... | 2 ... -6 .... 2

So the quotient and remainder upon dividing is

$\dfrac{2x^3+14x^2-58x}{x+10}=2x-6+\dfrac2{x+10}$

with a remainder of 2, which means $p(-10)=2$ .

What does b represent in the equation of a line in the form y=mc+b

Olin [163]

Do you mean y = mx + b instead of y = mc + b? In that case:

b in y = mx + b format is the y-intercept, as this kind of equation is called slope-intercept form.
