Answer:

m = ___<u>−1</u>___ b = ___<u>−9</u>___

Step-by-step explanation:

In the Slope-Intercept Formula, y = mx + b, <em>b</em><em> </em>represents the y-intercept, and <em>m</em><em> </em>represents the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>], so with that being said, you have your answer.

I am joyous to assist you anytime.

HELP ASAP!!!!<br> GIVING BRAINLIEST!<br><br> Find the value of x and y with the steps PLEASE.
PtichkaEL [24]

Answer:

x=70

y= 40

Step-by-step explanation:

the triangle containing x is an isosceles triangle so two of the sides are 55.

55+55+x=180.

110+x=180

110-110+x=180-110

x=70

Triangle BAC is equilateral so 180/3=60. Now

x+60+c=180

70+60+c=180

130+c=180

130-130+c=180-130

c=50

That gives us one corner of triangle CBD. We know a second angle is 90 so

50+90+y=180

140+y=180

140-140+y=180-140

y=40

I think that is correct but you are free to check it yourself

PLEASE SHOW FULL SOLUTIONS !!!!! WILL MARK BRAINLIEST FOR THE BEST ANSWER. THANK YOU AND GOD BLESS

Answer:

  • System is given below

Step-by-step explanation:

  • Let (applicable to all three lines below)
  • Hard candy = x kg with price $1.60/kg
  • Gummy worms = y kg with price $2.20/kg
  • Total weight = 50 kg with mixed price $1.75/kg

<u>Required equations:</u>

  • x + y = 50                        total weight
  • 1.60x + 2.20y = 50*1.75      total price

=========================================

<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>

<u>Simplify the second equation and solve by substitution x = 50 - y:</u>

  • 1.6(50 - y) + 2.2y = 87.5
  • 80 - 1.6y +2.2y = 87.5
  • 0.6y = 7.5
  • y = 7.5/0.6
  • y = 12.5

<u>Find the value of x:</u>

  • x = 50 - 12.5 = 37.5

<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg
