Solve the equation.
1/10 (x + 34) = −2(4 − x)
x = _____
HELPPP PLZZ DUEE TODAYY
Answers
Answer:
−0.383
Step-by-step explanation:
Let's solve your equation step-by-step.
1/10 (x+34)=(−2(4−x))(x)
Step 1: Simplify both sides of the equation.
1/10 x+ 17/5 =2x2−8x
Step 2: Subtract 2x^2-8x from both sides.
1/10 x+ 17/5 −(2x2−8x)=2x2−8x−(2x2−8x)
−2x2+ 81/10 x+17/5 =0
For this equation: a=-2, b=8.1, c=3.4
−2x2+8.1x+3.4=0
Step 3: Use quadratic formula with a=-2, b=8.1, c=3.4.
x=
−b±√b2−4ac
2a
x=
−(8.1)±√(8.1)2−4(−2)(3.4)
2(−2)
x=
−8.1±√92.81

x=−0.38344867082526823,4.433448670825268

Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.
Answers
Answer:2
Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.

Step-by-step explanation:
Here's what's going on: some person buying their furniture sees this sofa and it's $1200. That person sees theres a 1/3 off sale! They're happy and buy their sofa with a 20% off discount they got.
Now we have to find out if they should use the 20% off discount before or after adding the 1/3 off sale.
The answer is, they're both the same.
Say they add the 1/3 off sale discount and then use their 20% off discount. Find the 1/3 off sale: 1200 divided by 3 (because fractions are division problems) = 400. 20% of 400: 400 x 0.2 = 80. It's not just 80, because it's not an "only pay 20%" discount. 400 - 80 = 320. They'd pay $320 with this method.
This shows that using the 20% discount after the 1/3 off sale the customer spends $320.
Now let's calculate what happens if they use the discount after the 1/3 off sale. 20% of 1200: 1200 x 0.2 = 240. 1200 - 240 = 960. Now adding the 1/3 off sale: 960 divided by 3 = 320. They'd also pay $320 with this method.
If it's a short answer, you could just write something like, "No, both methods end up with the sales associate paying $320."
