Whats the step by step and answer for 15h+30<10h-45
Andreyy89
First, subtract 10h from 15h so the variables are on the same side. You get:
5h+30<-45

Then, you can solve the inequality like any other equation. Subtract 30 from -45:
5h<-75

Finally, divide -75 by 5 to get your answer:
h<-15

Vihaan finds that the roots of a quadratic equation that contains a difference of squares pattern is x = +-16. What is true abou
tigry1 [53]

The answer to the question, <u>What is true about the graph of the parabola described by the quadratic equation</u> is that the parabola crosses the x-axis at x = ±16.

Since the quadratic equation has roots x = ±16, it implies that its factors are x - 16 and x + 16.

So, the quadratic equation is y = (x - 16)(x + 16) = x² - 16²

Also, we know that the roots of a quadratic equation are the points where the value of the quadratic equation equals zero. At this value, the quadratic equations crosses the x-axis at the roots of the quadratic equation.

Since the roots of our quadratic equation are x = ±16, it implies that the parabola crosses the x-axis at x = ±16.

So, the answer to the question, <u>What is true about the graph of the parabola described by the quadratic equation</u> is that the parabola crosses the x-axis at x = ±16.

What is the slope of the line? ​
Alexxx [7]

Answer:

Should be, (-3,5) (if rise over run aka y,x)

Step-by-step explanation:

When attempting to find a slope like this, you need to locate pretty points. Pretty points are any time the line meets an exact corner on the box. If you look at -3,1, you can see the line makes a pretty point there. Then, try to find the next one, which is at 2,-3. Once you found these pretty points, try to connect them by drawing a line towards each other THAT IS STRAIGHT until those intersect. Where they intersect is where the slope of the line is. In this case, when I drew the line, they met at <em>down three</em>, <em>over (right) 5.</em>
