Answer:

y = x +1

Step-by-step explanation:

y= mx + b

where m is the slope and b is the y-intercept

m = (y2-y1)/ (x2-x1) = 2+4 / 3+3 = 6/6 = 1

from the point -slope equation we have

y-y1 = m* (x-x1)

y-3 = 1* ( x-2)

y= x -2+3

y= x +1

so the slope m=1 and the y-intercept b=1

Find the value of c that makes the trinomial a perfect square. x2+8x+c

Evgen [1.6K]

Answer:

c=16

Step-by-step explanation:

hello :

x2+8x+c is the perfect square means : x²+8x+c= (x+a)²

x²+8x+c = x²+2ax+a²

so : 2a=8

c=a²

a=8/2 = 4 but : c = a²

conclusion : c=16

M+1 3/8=5 What does m equal?

Arte-miy333 [17]

$\text{ The value of m is equal to 3.625 or }\frac{29}{8} \text{ or } 3\frac{5}{8}$

Solution:

Given that we have to find the value of "m"

Given expression is:

$m + 1\frac{3}{8} = 5$

Let us first convert the mixed fraction to improper fraction

Steps to follow:

Divide the numerator by the denominator.

Write down the whole number answer.

Then write down any remainder above the denominator.

Therefore,

$1\frac{3}{8}=\frac{8 \times 1+3}{8} = \frac{8+3}{8} = \frac{11}{8}$

Now the expression becomes,

$m + \frac{11}{8} = 5$

Keep the variable "m" on L.H.S and move the constant to R.H.S

$m = 5 - \frac{11}{8}\\\\m = \frac{5 \times 8 -11}{8}\\\\m = \frac{40-11}{8}\\\\m = \frac{29}{8}\\\\\text{In mixed fractions, we can write as }\\\\m = \frac{29}{8} = 3\frac{5}{8}$

Thus value of m is equal to 3.625 or $\frac{29}{8} \text{ or } 3\frac{5}{8}$

Which of the following represents the factorization of the trinomial below? x2 - 6x +9

valentinak56 [21]

For this case we must factor the following expression:

$x ^ 2-6x + 9$

We must find two numbers that, when multiplied, result in 9 and when added, result in -6.

These numbers are -3 and -3.

$-3-3 = -6\\-3 * -3 = + 9$

Then, the factored expression is of the form:

$(x-3) (x-3) = (x-3) ^ 2$

Thus, the correct option is option C.
