Answer 1

Answer:

i think that you are multiplying them so the answer is 3553.5

and if your adding it would be 122.1

What is the solution to the inequality?5x + 8 > –12

A.
x < –4

B.
x < 4

C.
x > –4

D.
x > 4

Answers

The steps to solving an inequality are: add or subtract from each side - multiply or divide both sides - simplify.

5x + 8 > -12
5x > -12 - 8
5x > -20
x > -20/5
x > -4

The answer is: x > -4

5x + 8 > -125x > -12-8. 5x> -20. 5/5x> -20/5. x > -4 C

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros? The equation has one zero because the discriminant is 1. The equation has one zero because the discriminant is a perfect square. The equation has two zeros because the discriminant is greater than 0. The equation has no zeros because the discriminant is not a perfect square.

Answers

The correct option is: The equation has two zeros because the discriminant is greater than 0.

Explanation:

First, remember the following conditions:
1. If the discriminant is less than zero, there will be no zeros.
2. If the discriminant is equal to zero, there will be one zero.
3. If the discriminant is greater than zero, there will be two zeros.

For the general equation of the form $ax^2 + bx + c = 0$ , the discriminant is $b^2 - 4ac$ .

Let's find the discriminant and then compare it with the conditions mentioned above.

Given Equation:
$3x^2 -7x + 4 =0$

a = 3, b = -7, c = 4

Now find the discriminant:

$b^2 - 4ac$
$(-7)^2 - 4(3)(4)$
Discriminant = 1

As the discriminant is greater than 0 (which in this case is 1), the equation has two zeros (as mentioned in the above conditions).

Write the equation in fully simplified slope intercept form

Answers

Answer:

y=-6x+3 can i have brainliest pls :)

Step-by-step explanation:

The first thing you have to do is find two points on the graph, in order to calculate the slope: (0,3) (1,-3)

Then use the slope formula= -3-3 / 1-0=-6 / 1= -6

then we use substitution to substitute a set of coordinate points with the slope by using slope-intercept form, y=mx+b

3=-6(0)+b (Simplify)

b=3

y=-6x+3

What is the equation of the line passing through the points (–5, –2) and (3, 14) in slope-intercept form?

Answers

Answer:

2x-y+2= 0

Step-by-step explanation:

(-5,-2)=(x1, y1)

(3, 14) =(x2, y2)

now,

slope(m)= y2-y1 / x2-x1

=14+2 / 3+5

= 16 /8

=2 units

passing point = (-5,-2) = x1,y1

now,

eqn of the line can be represented as,

y -y1 = m (x-x1)

y +2 = 2 (x +5)

y+2 = 2x +10

y = 2x+10-8

0 = 2x+2-y

2x-y+2 =0 is the required eqn
