Write the equation of the line that passes through (2, 4) and has a slope of –1 in point-slope form.

1 answer:

3 0

Y - y1 = m(x - x1).....this is point slope form
slope(m) = -1
(2,4)...x1 = 2 and y1 = 4
now we sub
y - 4 = -1(x - 2) <===

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi

PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

$a^2+b^2=c^2$

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

$10^2+b^2=26^2$

Solve the exponents

$100+b^2=676$

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

$100-100+b^2=676-100$

$b^2=576$

Take the square root of both sides

$\sqrt{b^2}=\sqrt{576}$

b=24

So, the other leg is 24 mm

Given the function f(X)= |3x-7|, find the values of X that satisfy the equation f(X) = 4

Kay [80]

Answer:

x = 1 or x = $\frac{11}{3}$

Step-by-step explanation:

The expression inside the absolute value function can be positive or negative

That is 3x - 7 = ± 4

There are 2 equations to solve

(1)

3x - 7 = 4 ( add 7 to both sides )

3x = 11 ( divide both sides by 3 )

x = $\frac{11}{3}$

(2)

3x - 7 = - 4 ( add 7 to both sides )

3x = 3 ( divide both sides by 3 )

x = 1
