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) <===

A tiger eats as much as 40 pounds if food at a time but it may go for several days without eating anything suppose a Siberian ti

lilavasa [31]

If I'm understanding this correctly:

Tiger consumes 18lb/day of food. If we want to calculate how much is consumed in 28 days, assuming that rate is consistent, the answer is 18*28 = 504lb of food.

Answer:

900 degrees

Step-by-step explanation:

Use the formula for interior angles

Sum = (n - 2) x 180

Sum = (7 - 2) x 180

Sum = 5 x 180

Sum = 900 degrees

Use the information to solve the triangle. Round your answers to two decimal places. Hint: draw a sketch first to determine if y

Anestetic [448]

Answer:

A = 43°

b = 25.8 (3 sig. fig.)

c = 14.5 (3 sig. fig.)

Step-by-step explanation:

Using angle sum of triangle, we get A = 180 - 104 - 33 = 43°

Using sin law,

b/sin104 = 18.1/sin43

b = 25.8 (3 sig. fig.)

c/sin33 = 18.1/sin43

c = 14.5 (3 sig. fig.)

What is the slope of this graph?

larisa [96]

Since the slope is falling, instead of rising, it would be negative.

Now, on the line, I plotted (0, 2) and (-2, 10).

You would now plug this into the rise/run formula.
The formula is $\frac{y2 - y1}{x2 - x1}$

The equation would become,
$\frac{10 - 2}{-2 - 0}$ = $\frac{8}{-2}$ = -4

I believe the answer would be -4.

I hope this helps!
