Answer:
x=1.528534
Explanation:
Simplify both sides of equation
4(2x-3)=0.2(x+5)/5.72
(4)(2x)+(4)(−3)=0.034965x+0.174825(Distribute)
8x+−12=0.034965x+0.174825
8x−12=0.034965x+0.174825
Step 2: Subtract 0.034965x from both sides.
8x−12−0.034965x=0.034965x+0.174825−0.034965x
7.965035x−12=0.174825
Step 3: Add 12 to both sides.
7.965035x−12+12=0.174825+12
7.965035x=12.174825
Step 4: Divide both sides by 7.965035.
7.965035x/7.965035=12.174825/7.965035
x=1.528534

2100/70 is 30
Answer:
y = -0.6x +3
Step-by-step explanation:
equation of the line through point (3, 1.2) and y-interecept of 3
y= mx+b
m is the slope and b is thhe y-intercept
y = mx + 3
between points (3, 1.2) and (0,3) the slope is
m= (y2-y1)/ (x2-x1) = (1.2-3) / (3-0) = -1.8/3 = -0.6
y = -0.6x +3
= 2x^2 - 20x + 49 = 2(x^2 - 10x + 49/2)
y= 2((x-5)^2 - 25 + 49/2) = 2((x-5)^2 - 1/2) = 2(x-5)^2 - 1
q =5, r=-1, p=2
Vertex = (q,r) = (5,-1)
