If a point (a,b) is reflected across the y-axis, the reflection point will be (-a,b)
(8,4) reflected over y-axis will be (-8,4)
(-16,-8) reflected over y-axis will be (16,-8)
(24,-16) reflected over y-axis will be (-24,-16)

Find the original price of a salt lamp that is $76 after a 20% discount.

makvit [3.9K]

Answer:

$76 x 1.20 = $92

$92 / 1.20 = $76

To keep and show decimals we divide 20 by 100 to show 1.02 then show any 2 placement decimals if none are shown in draft first then you can try in draft 20/1000 to see the difference between the decimals.

The longer leg of a right triangle is 6cm longer than the shorter leg and also 1cm longer than the hyptenese. find the perimeter

CaHeK987 [17]

X - a leg (x > 6);
x - 6 - a leg;
x + 1 - a hypotenuse;
Use the Pythagorean theorem
$(x+1)^2=x^2+(x-6)^2$

Use: $(a\pm b)^2=a^2\pm2ab+b^2$

$x^2+2x+1=x^2+x^2-12x+36\ \ \ |-x^2-2x-1\\\\x^2-14x+35=0\ \ \ |-35\\\\x^2-14x=-35\\\\x^2-2\cdot x\cdot7=-35\ \ \ |+7^2\\\\x^2-2\cdot x\cdot7+7^2=-35+7^2\\\\(x-7)^2=14\iff x-7=\pm\sqrt{14}\ \ \ |+7\\\\x=7-\sqrt{14} < 6;\ x=7+\sqrt{14}$

$x=7+\sqrt{14}\\x-6=1+\sqrt{14}\\x+1=8+\sqrt{14}$

The perimeter:

$7+\sqrt{14}+1+\sqrt{14}+8+\sqrt{14}=16+3\sqrt{14}$

Convert the following to Standard Form: (x - 5)^2 + 4

netineya [11]

Answer:

x² - 10x + 29

Step-by-step explanation:

The standard form of a quadratic is , ax² + bx + c (a ≠ 0 )

Given

(x - 5)² + 4 ← expand factor using FOIL

= x² - 10x + 25 + 4

= x² - 10x + 29 ← in standard form
