Write an equation for each condition 1) The line with a slope of 7 and a y-intercept of -1( in slope-intercept form)

2) The line that passes through (1,-5) and has a slope of 3 (in point-slope form)

Answers

Answer 1

Answer: 1.
$m=7\n b=-1\n\n y=7x-1$

2.
$y-y_1=m(x-x_1)\n y_1=-5\n x_1=1\n m=3\n\n y-(-5)=3(x-1)\n y+5=3(x-1)$

Megan has 25 phone numbers stored in her cell phone. Abby has some phone numbers stored in her cell phone. Together they have a total of 61 phone numbers stored. If n = the number of phone numbers Abby has stored in her cell phone, write a mathematical sentence to express the information above.

Answers

The mathematical sentence should be: 25+n=61

25+N=61.
N= 36
So there is 36 numbers in Abby's cell phone.

What is the sum of 2/10 and 3/10 in simplest form

Answers

The sum of 2/10 and 3/10 in simplest form is; 1/2

The sum of 2/10 and 3/10 is to be determined in simplest form;

Evidently, both fractions have the same denominator.

The question requires the sum and can be evaluated as follows;

2/10 + 3/10

since, the LCM of the denominators is 10; we then have;

=(2+3)/10.

=5/10

= 1/2.
