What is the slope intercept equation for a parallel line through (1,3), parallel to y=2x+5

Mathematics
1 answer:
Daniel [21]2 years ago
7 0

Answer:

the desired line is y = 2x+1

Step-by-step explanation:

A line parallel to y=2x+5 has a very similar equation.  All we have to do here is to write y=2x+5 as y=2x+b and find b for x = 1 and y = 3.

Replacing y with 3 and x with 1, we get 3 = 2(1) + b.  Then b = 1, and the desired line is y = 2x+1

How do I factor trinomials of a form ax^2+bx+c when a=1 <br><br> In one paragraph
vitfil [10]

Answer:

  • Trinomials in the form x^2+bx+c can often be factored as the product of two binomials.

Step-by-step explanation:

As we know that a polynomial with three terms is said to be a trinomial.

Considering the trinomial of a form

ax^2+bx+c

As

a = 1

so

x^2+bx+c

  • Trinomials in the form x^2+bx+c can often be factored as the product of two binomials.

For example,

x^2+7x+10

=\left(x^2+2x\right)+\left(5x+10\right)

=x\left(x+2\right)+5\left(x+2\right)

\mathrm{Factor\:out\:common\:term\:}x+2

=\left(x+2\right)\left(x+5\right)

Therefore, Trinomials in the form x^2+bx+c can often be factored as the product of two binomials.

Hi, can you help me answer this question, please, thank you!
frutty [35]

Given:

mean, u = 0

standard deviation σ = 1

Let's determine the following:

(a) Probability of an outcome that is more than -1.26.

Here, we are to find: P(x > -1.26).

Apply the formula:

z=\frac{x^{\prime}-u}{\sigma}

Thus, we have:

\begin{gathered} P(x>-1.26)=\frac{-1.26-0}{1} \\  \\ P(x>-1.26)=\frac{-1.26}{1}=-1.26 \end{gathered}

Using the standard normal table, we have:

NORMSDIST(-1.26) = 0.1038

Therefore, the probability of an outcome that is more than -1.26 is 0.1038

(b) Probability of an outcome that

Answer: y = 5x

Step-by-step explanation:

(check to make sure it matches the graph)

y = 5(0) = 0

y = 5(2) = 10

y = 5(4) = 20

y = 5(6) = 30

y = 5(20) = 100 dollars

A road crew much repave a road that is 4/5 miles long. They can repave 1/20 miles each hour. How long will it take the crew to r
lutik1710 [3]

Answer:

16 hours

Step-by-step explanation:

Multiply the 4/5 by 4 to get the denominator as 20. So you do 4 x 4 which equals 16 and 5 x 4 which equals 20 so you get 16/20 miles or 16 hours.
