6 0

Answer:

It would be 60 degrees

Step-by-step explanation:

You take the numbers and write the equation 34-(-26) to figure out the difference. You then change the signs, making it 34+26, as before you were subtracting a negative. If you complete that problem, you come to the conclusion of 60.

Graph the line with slope 2/3 passing through the point (-3,-3)

Yakvenalex [24]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The equation of given line is ~

$y = \dfrac{2}{3} x - 1$

$\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}$

Let's use the point slope form of line to find the equation of given line ~

that is ~

$y - y_1= m(x - x_1)$

$y - ( - 3) = \dfrac{2}{3} (x - ( - 3))$

$y + 3 = \dfrac{2}{3} (x + 3)$

$y + 3 = \dfrac{2}{3} x + 2$

$y = \dfrac{2}{3} x + 2 - 3$

$y = \dfrac{2}{3} x - 1$

given a system of equations, list three ways that we can write new equations that can be used to create equivalent systems

cupoosta [38]

Answer:

See explanation

Step-by-step explanation:

Given a system of equations, you can

rewrite one of the equations and write the sum of two equations instead of the second equation;

rewrite one of the equations and write the difference of two equations instead of the second equation;

rewrite one of the equations and write the sum of the first equation multiplied by one nonzero number and the second equation multiplied by another nonzero number instead of the second equation.

These actions are called elementary row operations. Elementary operations with system of equations do not change the solution set.

What is the inequality of 0 < a < 6 on a numberline

pickupchik [31]

The given inequality is expressed as

0 < a < 6

This means that the values of a that would satisfy the inequality are numbers between 0 and 6 but both 0 and 6 are not inclusive. This would be shown by not making solid circles at 0 and 6. The number line is shown below
