Rewrite this inequality so y is by itself: 3x − 4y ≥ 24.

vazorg [7]

Answer:

y $\leq$ 6 + $\frac{3x}{4}$

Step-by-step explanation:

3x - 4y $\geq$ 24

-3x -3x

(-4y $\geq$ 24 - 3x ) / -4

y $\leq$ 6 + $\frac{3x}{4}$

Which of the filling units are units of length

dimaraw [331]

Answer:

The SI unit for length is the meter (abbreviated m); its definition has also changed over time to become more accurate and precise. The meter was first defined in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.

I need help with these questions (see image). Please show workings.

shtirl [24]

Answer:

Inscribed angle is half of the intercepted arc.
Central angle is the same size as the intercepted arc.

As per above two statements we have:

y = 2*58° = 116°

and

z = 90°/2 = 45°

{ x - 3y= -3 & x + y= 5 We are to use the graph to solve the given system of equations, then enter your solution below. I ge

nasty-shy [4]

Answer:

Solution: (3, 2)

Step-by-step explanation:

It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.

x - 3y = -3

-3y = -x - 3

Divide both sides by -3:

$\frac{-3y}{-3} = \frac{-x - 3}{-3}$

y = 1/3x + 1

where slope = 1/3

y-intercept = 1

x + y = 5

Subtract x from both sides to isolate y:

x - x + y = - x + 5

y = -x + 5

where slope = -1

y-intercept, 5

I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, x - 3y = -3 is the blue line, while x + y = 5 is the green line. Their intersection occurs at point, (3, 2).

Therefore, the solution is (3, 2).
