Answer: OPTION A.

Step-by-step explanation:

By definition:

- When you reflect a figure, you flip it over a line of reflection, then, both figures will be in opposite directions.

- The image (which is the reflection) and the pre-image will have the same shape ad size.

- If a figure is reflected over the y-axis, then the sign of the x-coordinate is changed.

Keeping the above on mind, you can conclude that when a triangle is reflected over the y-axis the coordinates of the vertices are afectted as following:

- The y-coordinate is not changed.

- The sign of the x-coordinate is changed.

Then:

$(x,y)$ → $(-x,y)$

Write an equation to solve each problem and then solve it. b In a 3-digit number, the hundreds digit is four more than the ones

Misha Larkins [42]

Answer:

digits are: 0, 4, 8. The required number is: 480.

Step-by-step explanation:

→ Let ones digits is 'x', then according to the condition the hundreds digit is 'x+4', and the tens digit is '2(x+4)'.

→ According to the condition the sum of the digits is: x+(x+4)+2(x+4)=12.

→ After evaluation this equation, x=0 - this is ones digit;

→ x+4=0+4=4 - this is hundreds digit;

→ 2(x+4)=2(0+4)=8 - this is ten digit.

Please help me solve this 5^2x=7^x+1

denis23 [38]

Answer:

$x=\frac{ln7}{2ln5-ln7}$

Step-by-step explanation:

5^2x=7^x+1 ⇔ ln5^2x = ln7^x+1 ⇔ 2xln5 = (x+1)ln7 ⇔ (2ln5-ln7)x = ln7

⇔ x = ln7/(2ln5-ln7)

I need help with these ASAP thanks

Nataly_w [17]

Answer:

a. $y=\frac{2x}{x-5}$

b. $y=\frac{2-4x}{x-3}$

Step-by-step explanation:

change switch x and y and then solve for y.

a. $x=\frac{5y}{y-2}$

$x(y-2)=5y$

$xy-2x=5y$

$xy-5y=2x$

$y(x-5)=2x$

$y=\frac{2x}{x-5}$

same for b.

b. $x=\frac{3y+2}{y+4}$

$x(y+4)=3y+2$

$xy+4x=3y+2$

$xy-3y=2-4x$

$y(x-3)=2-4x$

$y=\frac{2-4x}{x-3}$

The scale drawing of a building has a width of 4 inches and a height of 8 inches. If the width of the actual building is 32 feet

kirill115 [55]

Hello!

First you have to find the scale

32 / 4 = 8

To get the actual building you multiply the scale building by 8 and change the units to feet

8 * 8 = 64ft

The answer is 64ft

Hope this helps!
