Y+4x=0 how can I solve to know if it's a direct variation?

subtract 4x from both sides and you get y=4x

y varies directly with x. When x is 1, y is 1/4. when x is 4, y is 1. when x is 8, y is 2. So on and so on. Sorry if this is confusing. Direct variations is one of my weak points

48

Step-by-step explanation:

Es un proceso de dos pasos para crear todos los pares de factores de 48: Primero, enumeramos todos los factores de 48. Luego, combinamos todas las diferentes combinaciones de factores para obtener todos los pares de factores de 48.

Todas las diferentes combinaciones de pares de los factores de 48 anteriores son los pares de factores de 48. A continuación se muestra la lista de todos los pares de factores de 48. Como puede ver, todos los pares de factores de 48 equivalen a 48 cuando los multiplica

It is a two-step process to create all the Factor Pairs of 48: First, we list all the factors of 48. Then, we pair all the different combinations of factors to give you all the Factor Pairs of 48.

All the different pair combinations from the factors of 48 above are the Factor Pairs of 48. Below is the list of all the Factor Pairs of 48. As you can see, all Factor Pairs of 48 equal 48 when you multiply them together.

Please help me with number ten and twelve
jasenka [17]

Answer: 93,\ 34^{\circ}

Step-by-step explanation:

Given

For figure (i) both triangles are congruent

\therefore 8x-27=4x+33\\\Rightarrow 8x-4x=33+27\\\Rightarrow 4x=60\\\Rightarrow x=15

\Rightarrow PQ=8x-27\\\Rightarrow PQ=93

For figure (ii)

Two triangles WXZ and WZY are congruent

\therefore 9x-28=5x-8\\\Rightarrow 4x=20\\\Rightarrow x=5^{\circ}\\\Rightarrow \angle YWX=2(9x-28)\\\Rightarrow \angle YWX=2(17)\\\Rightarrow \angle YWX=34^{\circ}

Which graph is a translation of f(x) = x^2 according to the rule y = x^2-5
Anestetic [448]

y = A(Bx - C)ⁿ + D

A is a vertical stretch (or shrink if |A| < 1

B is a horizontal shrink by factor of \frac{1}{B} (or stretch if |B| < 1)

C is a shift to the right (or left if C is negative)

D is a shift up (or down if D is negative)

*************************************************

y = x² - 5     ⇒ D = -5    

Answer: shift down 5 units
