<span>A. Calculate the value of x.</span>
Okay, if the jeans were originally $80, take 40% off of that (40% of 80 is 32) so you’d get 48. Now take 48 and multiply by 1.07 (to get 107% of the $48, to find a percentage you can move the decimal place left 2 digits and multiply), so Justin would pay $51.36 in total.
Hey There!
The answer to your problem is
or
both answers are correct!
<u>Step 1: Subtract x²+12 from both sides.</u>
−7x−(x²+12)=x²+12−(x²+12)
−x²−7x−12=0
<u>Step 2: Factor left side of equation.</u>

<u>Step 3: Set factors equal to 0.</u>

Answer:
- A'(-3, 12)
- B'(9, 6)
- C'(-6, -6)
Step-by-step explanation:
Dilation about the origin multiplies each coordinate value by the dilation factor.
For dilation factor k, the new coordinates are ...
(x, y) ⇒ (kx, ky)
Your dilation factor is 3, so the transformation is ...
(x, y) ⇒ (3x, 3y)
A(-1, 4) ⇒ A'(-3, 12)
B(3, 2) ⇒ B'(9, 6)
C(-2, -2) ⇒ C'(-6, -6)
Answer:
a)F
b)A
c)F
d)F
Step-by-step explanation:
a)3+4=7 which is the total number of pupils in class
So, the fraction should be 3/7✅not 3/4❌
b) The girls in the class are 4 and the total number of pupils in class are 7. So, the fraction is correct✅.
c) The number of boys in class is 3✅ which is given in the ratio. Not 6❌
d) If you add the both numbers in the ratio, you will get the total number of pupils which is 7✅not 12❌
Hope this will help ya!
