X2 +x − 4 = 0

Mathematics
1 answer:
Rus_ich [418]3 years ago
3 0

Answer:

  • a=1
  • b=1
  • c=-4
  • x =  (-1 ±√17)/2

Step-by-step explanation:

The coefficient of x^2 is "a". That is 1.

The coefficient of x is "b". That is 1.

The constant term is "c". That is -4.

The values of a, b, and c are 1, 1, and -4, respectively.

_____

The solution is ...

  x = (-b ±√(b^2-4ac))/(2a)

Filling in the values of a, b, and c, this is ...

  x = (-1 ±√(1^2 -4·1·(-4)))/(2·1)

  x = (-1 ±√17)/2

How many 10 oz servings are in a 5-quart pitcher of lemonade?<br><br>There are ? Servings
Ira Lisetskai [31]

Answer:

There are 16 servings

Step-by-step explanation:

<u>First, find how many oz are in 5 quarts. </u>

<em>Think: In one quart there are 32 ounces, in 5 quarts how many ounces would that be?</em>

5 x 32 = 160 ounces

<u>Next, divide 160 ounces by 10 servings</u>

160 / 10 = 16 servings

So there are 16 servings in a 5 quart pitcher.

Hope this helps ;)

One linear equation is defined by points (1, 6) and (3, 7), while the other is defined by points (3, 6) and (5, 8). Which point
zysi [14]
So we need to find the two lines...y=mx+b where m is the slope and b is the y-intercept.

m=(dy/dx)=(7-6)/(3-1)=1/2 so

y=x/2+b, now I'll use (1,6) to solve for b

6=1/2+b, b=5 1/2=11/2 so

y1=(x+11)/2

now the other line...

m=(8-6)/(5-3)=2/2=1

y2=x+b, using point (3,6) we solve for b

6=3+b, b=3 so

y2=x+3

Since this is just two lines they will only intersect at a single point and when they do, y=y so we can say:

x+3=(x+11)/2

2x+6=x+11

x+6=11

x=5, now use either line to solve for the corresponding y value...

y2=x+3 becomes y=5+3=8 so the solution to this system is the point:

(5,8)
