Answer:

420 miles in 2 hours.

If it where to fly for 13 hours then you divide 420 by 2 which is 210. Multiply 210 by 13.

=2730 miles.

The rate of speed would be 420 divided by 2. This would equal 210 miles per hour.

Answer:

The jet could fly 2730 miles in 13 hours. The rate of speed of the jet is 210 miles per hour.

Step-by-step explanation:

420/2=x/13

simplify 420/2 into 210

x/13=210

x=210*13

x=2730

What’s the answer to 6x + 3y =
Alex73 [517]

Answer:

The last answer; 12.

Step-by-step explanation:

In order to solve this, use substitution. Since it gives you an equation for y, substitute that equation in the other formula as y. This will give you:

6x+3(-2x+4)=?

Then simplify:

6x-6x+12=?

Since 6x - 6x cancels out, you are left with 12.

?=12\\

Below are two different functions, f(x) and g(x). What can be determined about their slopes?
worty [1.4K]
<h3>Answer: B) the function g(x) has a larger slope</h3>

===================================================

Explanation:

The slope of f(x) is 4, since the equation y = 4x+2 has slope m = 4. Compare this to y = mx+b.

The slope of g(x) is 5. Note how if we started at (0,-2) on the red line and moved up 5 and to the right 1, we arrive at (1,3) which is another point on the red line. You could use the slope formula

m = (y2-y1)/(x2-x1)

to get the same result.

Since the slope of f(x) is 4 and the slope of g(x) is 5, we see that g(x) has a larger slope. The g(x) line is steeper compared to f(x).

Plz help urgent so easy will give brainliest mark for the first answer given!!
timama [110]

Answer:

Step-by-step explanation:

6). Equation of the line has been given as,

    4x + 9y = -9

    By converting this equation into y-intercept form,

    9y = -4x - 9

    y=-\frac{4}{9}x-\frac{9}{9}

    y=-\frac{4}{9}x-1

    By comparing this equation with y = mx + b

    Here, m = Slope of the line

    b = y-intercept

    Slope of the equation (m) = -\frac{4}{9}

    y-intercept (b) = -1

8). Equation of the line is,

    5x + 3y = 12

    3y = -5x + 12

    y=-\frac{5}{3}x+\frac{12}{3}

    y=-\frac{5}{3}x+4

    Slope of the line = -\frac{5}{3}

    y-intercept = 4
