x² + 4x + 3 = 0

Can someone please help me solve this quadratic equation

Answers

Answer 1

Answer:

Step-by-step explanation:

x= -1 and -3

What when multiplied is +3 but when added is 4? 3 and 1. You then get (x+3)(x+1) is the first part of the answer. If you want to find x, set x+3 to 0. x+3=0. Then subtract 3 from both sides to get x by itself. x= -3. Do the same with the x+1.

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 8 and (0, 3) → c = 3

y = - 8x + 3 ← equation of line

Four years ago, Sam invested in Grath Oil. She bought three of its $1,000 par value bonds at a market price of 93.938 and with an annual coupon rate of 6.5%. She also bought 450 shares of Grath Oil stock at $44.11, which has paid an annual dividend of $3.10 for each of the last ten years. Today, Grath Oil bonds have a market rate of 98.866 and Grath Oil stock sells for $45.55 per share. Use the scenario above to consider which statement best describes the relative risk between investing in stocks and bonds.

Answers

Answer:

C. The market price of the bonds is more stable than the price of the company's stock.

Step-by-step explanation:

In the context, Sam bought some bonds at the market price from Grath Oil and also invested in buying corporate shares which paid a dividend of $3.10 for each share annually for a period of ten years.

At present the market value of the bonds of Grath Oil is more. The market price of the bond is the amount of the money to be paid in an open market to buy a bond.

So the bond's market price is much more stable than the price of the company's stock. It is riskier to invest in company stocks.

Find the value of X that makes m||n Two parallel lines, m and n intersected by a transversal line. A pair of alternate exterior angle are marked left-parenthesis 4 x plus 24 right-parenthesis degrees and 8 x degrees.

Answers

Answer:

6

Step-by-step explanation:

Given  a pair of alternate exterior angle of 4x + 24 and 8x, we are to find the value of x that will make m and n parallel.

Alternate exterior angles are equal, hence;

4x + 24 = 8x

24 = 8x - 4x

24 = 4x

Rearrange

4x = 24

Divide both sides by 4

4x/4 = 24/4

x = 6

Hence the value of x required is 6

60°

Step-by-step explanation:

Because of the rule that all triangle's angles must measure to 180°.

So I did...

60+60=120

180-120= 60

Answer

60 degrees

Step-by-step explanation:

A triangle is 180 degrees. So if you add both 60 degrees it would equal 120, substracted by 180 and you'll get 180. Or if you want to go the faster way, remember that a triangle will equal 180.

Answer:

4t+8

Step-by-step explanation:

If you look at your equation t+8+3t you will notice how you have two t parts

part 1: t

part 2: 3t

Since they have the same variable or letter you are able to combine them. When you add them together you get 4t.

6. Janet makes scarves to sell at the craft fair. Each scarf requires 2.5 yards of yarn. A. At the fabric store, yarn is sold by the foot. If Janet wants to make 84 scarves, how many feet of yarn must she buy?

Answers

Answer:

610 feet

Step-by-step explanation:

From the question :

1 scarf = 2.5 yards of yarn

84 scarves = x yards

Cross Multiply

1 scarf × x yards = 84 × 2.5 yards

x yards = 210 yards

Hence, 84 scarves require 210 yards

Converting yards to feet

1 yard = 3 feet

210 yards = x feet

x feet × 1 yard = 210 yards × 3 feet

x feet = 210 yards × 3 feet/1 yards

x feet = 610 feet

Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn

9.054 x 10^-6 in standard form

Answers

0.000009054
it’s five zeros after that decimal.

Required standard form is 0.000009054.

What is value of 9.054 x 10^-6 in standard form ?

Some examples of standard form of Mathematics,

Example -1:

[tex]0.5 \times {10}^{2} \\ = 0.5 \times 100 \\ = 50[/tex]

Example-2 :

[tex]0.254 \times {10}^{ - 2} \\ = \frac{0.254}{ {10}^{2} } \\ = \frac{0.254}{100} \\ = 0.00254[/tex]

Example-3 :

[tex]3.3548 \times {2}^{2} \\ = 3.3548 \times 2 \times 2 \\ = 13.4192[/tex]

Example -4 :

[tex]5.55 \times {3}^{2} \\ = 5.55 \times 3 \times 3 \\ = 48.95[/tex]

So,we can say that standard form means simplest form.

Here given,

[tex]9.054 \times {10}^{ - 6} \\ = 9.054 \times \frac{1}{ {10}^{6} } \\ = \frac{9.054}{1000000} \\ = 0.000009054[/tex]
