Answer:
y = -25x + 170
Step-by-step explanation:
For the graph equation y = ax + b, we have to find a and b.
Pick two points that are on the grid for best accuracy.
e.g., (2,120) and (6,20)
Then a = (20-120)/(6-2) = -25
b is the y coordinate of the line with the y axis: 170
So the formula is:
y = -25x + 170

I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?
Answers
Answer:
Cost of 110 g bag = $ 0.132
Step-by-step explanation:
As we know ,
1 kg = 1000 g
⇒1000 g = 1 kg
⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg
⇒110 g = 110 (0.001) kg = 0.11 kg
⇒110 g = 0.11 kg
Now,
Cost of 10 kg bag = $12
⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]
⇒Cost of 1 kg bag = $ 1.2
⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132
∴ we get
Cost of 110 g bag = $ 0.132

15) m∠A = 21°, m∠B = 125°, m∠C = 34°
16) m∠J = 48°, m∠K = 57°, m∠L = 75°
Explanation:
15) m∠A is thirteen less than m∠C, so if you were to translate that into numerical terms, it would be (x-13). m∠B is eleven less than four times m∠C, so that would be (4x-11). Because the angles of a triangle sum up to 180°, the equation for this scenario would be (x-13)+(4x-11)+x=180. (X is a variable for m∠C. Add all the like terms to get 6x-24=180. Add 24 to both sides to get 6x=204. Divide 6 on both sides to get x=34. Now that we know m∠C, we can substitute 34 into x to get m∠A as 21° and m∠B as 125°.
16) m∠K is 9 more than m∠J, which is (x+9). m∠L is 21 less than twice m∠J, which is (2x-21). Again, a triangle's angles sum up to 180°, so the equation would be (x+9)+(2x-21)+x=180. Add the like terms to get 4x+(-12)=180. Add 12 to both sides to get 4x=192. Divide 4 on both sides to get x=48. Substitute 48 for x to get m∠K = 57° and m∠L=75°.
