Answer:

8.5 in

Step-by-step explanation:

You are solving for the hypotenuse right? So you would use this formula:

c = square root a^2+b^2

the c is the hypotenuse (long side of a right triangle) and a will be 4 and b will be 7.5. substitute the numbers in, solve, and you get 8.5 inches!

x = square root 4^2 + 7.5^2

x = square root 16 + 56.25

x = square root 72.25

x = 8.5 inches

Find the gradient of the line <br><br> 3y + 2x = 1<br><br> how to guys
kykrilka [37]

Answer:

-2/3

Step-by-step explanation:

The gradient of a line is its slope. You can just convert the equation to slope-intercept form (y=mx+b where "m" is the gradient/slope):

3y + 2x = 1

3y = 1 - 2x

y = 1/3 - 2/3x

y = -2/3x + 1/3

So, as we can see, -2/3 is the gradient/slope of the line.

What is the slope of the line (2,3) (1,-2)?
jarptica [38.1K]

Answer: The slope is 5

Step-by-step explanation:

You can calculate the slope of the line with this fomula:

m=\frac{y_2-y_1}{x_2-x_1}

Given the points (2,3) and (1,-2), you can identify that:

y_2=-2\\y_1=3\\x_2=1\\x_1=2

Now, the final step is to substitute these values into the formula  m=\frac{y_2-y_1}{x_2-x_1}, getting that the slope of this line is:

 m=\frac{-2-3}{1-2}

m=\frac{-5}{-1}\\\\m=5
