Pythagorean theorem: a² + b² = c² 

a² and b² are the legs, and c² is the hypotenuse.

Plug in 9 to a² and b² since you know that both the right triangle's legs are 9 cm.

9² + 9² = c²
81 + 81 = c²
162 = c²

Square root both sides.

c = 12.7 cm

<u>Answer:</u>

y = -\frac{2}{3}x + 490

gradient = = -\frac{2}{3}

y-intercept = 490

<u>Step-by-step explanation:</u>

• The slope-intercept form of an equation takes the general form:

\boxed{y = mx + c},

where:

m = slope,

c = y-intercept.

• We are given the equation:

2x + 3y = 1470

To change this into the slope-intercept form, we must make y the subject:

3y = -2x + 1470          [subtract 2x from both sides]

⇒ y = -\frac{2}{3}x + \frac{1479}{3}        [divide both sides by 3]

⇒ y = -\frac{2}{3}x + 490

• Comparing this equation with the general form equation, we see that:

m = -\frac{2}{3}

c = 490.

This means that the gradient is \bf -\frac{2}{3}, and the y-intercept is \bf 490.

What is the equation of the line with a slope of 3/4 that goes through the point (4, 1) in slope-intercept form?
Svetach [21]

Answer:

y=\frac{3}{4}x+-2

Step-by-step explanation:

We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is y -y_{1} =m(x -x_{1}) where we substitute a point (x,y) for (x_{1},y_{1}).  

We have m=3/4 and (4, 1). We input m and x_{1} =4\\y_{1}=1.

y-1=\frac{3}{4} (x-4)

We now simplify the parenthesis and solve for y.

y-1=\frac{3}{4} (x-4)\\y-1=\frac{3}{4}x+\frac{3}{4} (-4)

We convert -4 into a fraction with 1 as the denominator.

y-1=\frac{3}{4}x+\frac{3}{4} (\frac{-4}{1} )\\y-1=\frac{3}{4}x+\frac{-12}{4}\\y-1=\frac{3}{4}x+-3

We add 1 to both sides to isolate y,

y-1+1=\frac{3}{4}x+-3+1\\y=\frac{3}{4}x+-2

This is slope intercept form. The line as slope 3/4 and y-intercept (0,2) or b=2.
