Answer:

y = -4x+14

Step-by-step explanation:

First find the slope

m = (y2-y1)/(x2-x1)

m = (2-10)/(3-1)

  =-8/2

  = -4

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -4x+b

Substitute a point into the equation

10 = -4(1)+b

Add 4 to each side

14 = b

y = -4x+14

Answer:

y=-4x+14

Step-by-step explanation:

m=y1-y2/(x1-x2) and m= y-y1/x-x1

10-2/1-3=-4

m=-4     so          -4=y-10/x-1

                           -4x+4=y-10

                            -4x+14=y

Answer:

  P(0, 4), Q(-3, 0)

Step-by-step explanation:

To find the y-coordinate of P, replace x with 0 and solve for y:

  3y = 12

  y = 4 . . . . . divide by 3

__

To find the x-coordinate of Q, replace y with 0 and solve for x:

  -4x = 12

  x = -3 . . . . . divide by -4

Then the intercepts are P(0, 4) and Q(-3, 0). The line is drawn through those points for the indicated values of x.

Someone want to help me with some Geometry?
Aleks04 [339]
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.

A sporting goods store offers 40% discount on all golf clubs. Rocco spent 20% of the money in his savings account on a golf putt
MatroZZZ [7]

Answer:

Rocco doesn't have enough money to buy the golf irons

Step-by-step explanation:

step 1

Find the rest of the money left in the savings account

using proportion

\frac{\$48}{20\%}=\frac{x}{80\%}\\ \\x=48*80/20\\ \\x=\$192

step 2

we know that

The set of golf irons has an original price of $359

Applying 40% discount

100%-40%=60%=60/100=0.60

after the discount the price will be

0.60(\$359)=\$215.4

\$215.4> \$192

therefore

Rocco doesn't have enough money to buy the golf irons
