Multiply.<br>(2x-5) (3x-7)​
Naya [18.7K]

Answer:

6x^2 -29 +35.

Step-by-step explanation:

use the FOIL method(First, Outer,Inner, and Last.)

2x x 3x=6x^2.

2x x -7=-14x.

-5 x 3x =-15x.

-5 x -7=35.

= 6x^2 -14x -15x+35

6x^2 -29x +35.

Sanjay and felipe are putting together a 500-piece puzzle. sanjay could do the entire puzzle by himself in 6 hours, while it wou
lisov135 [29]

Sanjay and Felipe would take a time of 3.4 hours to do the puzzle if they were working together.

<h3>What is the time?</h3>

Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present and into the future.

The amount of time that something exists or continues to happen as measured or measurable.

The duration of events or the gaps between them can be measured, compared, or even ordered using time.

Time taken by Sanjay= 6 hours

Time taken by Felipe= 8 hours

Time taken by both if they work together,

=\frac{1}{1/6+1/8}

=\frac{1}{\frac{4+3}{24} }

=24/7

=3.4 hours

I need help with number 13
nikklg [1K]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

We have the point (0, 5). Therefore b = 5.

We have: y = mx + 5

Other point (3, 2). Substitute the coordinates of the point to the equation of the line:

2=3m+5     <em>subtract 5 from both sides</em>

-3=3m      <em>divide both sides by 3</em>

-1=m\to m=-1

<h3>Answer: f(x) = -1x + 5 = -x + 5</h3>

Please help!
lakkis [162]

Answer:

A) slope of f(x) = 3 , slope of g(x) = 7

B) y intercept of f(x) is  0  and g(x)  is 2

So g(x) has greater y intercept

Step-by-step explanation:

Lets find equation of f(x) using the given table

LEts take two points from the table (0,0) (1,3)

slope = \frac{y_2-y_1}{x_2-x_1} = \frac{3-0}{1-0} = 3

we use equation y=mx+b

where m is the slope and b is the y intercept

we got m = 3, we use (0,0) and find out b

y=mx+b

0 = 3(0) + b

so b=0

So equation for f(x)= 3x +0

slope =3  and y intercept = 0

For equation g(x) = 7x +2 , slope = 7  and y intercept = 2
