What is 7x squared+2x=0 by factoring quadratic equations?

Answers

Answer 1

Answer: lets solve the quadratic equation:
7x^2 + 2x = 0
(x)(7x + 2) = 0
therefore, for this equation to hold we need, either one of these conditions:
x = 0
or
7x + 2 = 0
from where:
7x = -2
x = -2/7
then, we have two solutions for the equation as expected being quadratic.

Write the slope-intercept form of the equation of the line through the given points. through: (3, -4) and (-4, 4)

Answers

first, you need your slope. this can be found by the slope formula: m = (y2 - y1)/(x2 - x1)

(3, -4) and (-4, 4)
(x1, y1) and (x2, y2)

m = (4 - -4)/(-4 - 3)
m = (8)/(-7)
so your slope is -8/7

now, to find a line through the given points, the only piece of information you're missing is your y-intercept. you just have to pick one point and plug it into slope-intercept form: y = mx + b, then solve for b

(-4) = (-8/7)(3) + b
-4 = -24/7 + b
-4/7 = b

so plug all of it into y = mx + b:

y = (-8/7)x - 4/7

please help me write it in simplest form

Answers

Answer:

Therefore, the simplest form of the expression "A + 5a + 5a" is "A + 10a"

Step-by-step explanation:

To simplify the expression "A + 5a + 5a" in its simplest form, we can combine like terms. "A" and "5a" are like terms because they both have the variable "a" raised to the power of 1. So, combining "A" and "5a" gives us: A + 5a + 5a = A + 10a

If sin theta is -4/5. 270 degrees is less than theta and theta is less than 360 degrees. What is tan theta?

Answers

Answer:

tan theta = -4/3.

Step-by-step explanation:

The inequality means that theta is in the 4th quadrant ( between 270 and 360 degrees.

The angle whose sine is 4/5 is 53.13 degrees.

So the angle whose sine is -4/5 is 306.87 degrees.

The tangent is negative and the triangle formed by the angle in the 4th quadrant has sides 3, - 4 and 5 ( by the Pythagoras theorem).

So tan theta = opposite / adjacent = -4/3 (answer).
