Use the graphs to estimate both solutions to x^2+x-4=0

Mathematics
1 answer:
Bogdan [553]3 years ago
4 0

Answer:

No graph so we'll use the quadratic formula

x^2+x-4=0

a = 1

b = 1

c = -4

x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2

x = (-1 +- sqr root (1 +16) ) / 2

x1 = (-1 + sqr root (17)) / 2

x2 = (-1 - sqr root (17)) / 2

Step-by-step explanation:

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\frac{1}{2}x+7

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Simplifying the equation...}}\\\\\frac{1}{2}(x+14)\\------------\\\rightarrow \frac{1}{2}*x = \frac{1}{2}x\\\\\rightarrow\frac{1}{2}*14=7\\\\\rightarrow     \frac{1}{2}(x+14)= \boxed{\frac{1}{2}x+7}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Hitman42 [59]

Answer:

Here, b represents buying fins and leashes.

As per the statement:

Vincent is ordering accessories for his surfboard. A set of fins cost $24 each and a leash costs $15.

A set of fins cost $24 each and a leash costs $15

⇒ Cost of total fins = 24 b and Cost of total leashes = 15 b

It is also given that: The shipping cost is $4 per order.

then;

Cost in dollars of buying b fins and b leashes plus the cost of shipping

= 24b+15b+4

Therefore, the expression  24b+15b+4 represents the cost in dollars of buying b fins and b leashes plus the cost of shipping.

10

(a)

True.

The given terms in the expressions are 24b, 10b and 4

(b)

True.

Like terms are those which have same variable.

Like terms in the given expression are: 24 b and 15 b

(c)

False.

Combine like terms in the given expression:

 39b+4

Therefore, the simplified given expression is,   39b+4
