Find the slope-intercept form of the equation of the line that passes through the point P and makes angle with the positive x-

SIZIF [17.4K]

Answer:

The answer is " $y= -x+7$ "

Step-by-step explanation:

If $\bold{\theta = 135^{\circ}}$

point: $p=(2,5)$

Formula:

$\to m= \tan \theta \\\\\to (y-y_1)= m(x-x_1)$

$\to m= \tan \ 135^{\circ} = -1\\\\\to x_1= 2\\\\\to y_1=5$

Put the value in the above formula:

$\to y- 5 = -1(x-2)\\\\\to y- 5 = -x+2\\\\\to x+y = 5+2\\\\\to x+y=7$

$\to y= -x+7$

2. How many terms are there in the expression: 3a + 6

Aliun [14]

Answer: 2

Step-by-step explanation: That expression is a binomial in any case the terms in a polynomial are separated by a plus or minus sign (+,-) so you can determine the number of terms by counting how many number or variable are being separated (ex: 3a+a-1 would have 3 terms and be a trinomial)

Mary weighs n kg while her sister weighs 15 kg less. How many times is Mary heavier than her sister?

kari74 [83]

Answer:

Mary is $\frac{n}{n-15}$ times heavier than her sister

Step-by-step explanation:

Mary's Weight = n

Sister's Weight = n - 15

To find how many times mary is heavier, we need to multiply "that many time" [let it be x] with sister's weight to get Mary's weight.

<u>e.g. </u>If someone weighs 100 and another person 50, 50 * 2 = 100, thus, 100 kg person is 2 times heaving. We do same for this:

(n - 15) * x = n

x = n/(n - 15)
