quita los paréntesis: 4x-5=2+3(x-3) multiplica paréntesis X3, elimina el paréntesis: 4x-5=2+3x-9 calcule: 4x-5= -7+3x mueve los términos y te quedará así: 4x-3x-5=-7

agrupe los términos semejantes: x=-7+5

calcular la suma, y el resultado final sería: x= -2

Which graph represents a proportional relationship? <br>​
Alina [70]

Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

Please help with multiple choice question
Volgvan

Answer:

D:   {9, 21, 33}

Step-by-step explanation:

Ken worked 2, 8 and 14 hours on 3 separate days.

For working 2 hours, his earnings were f(2) = 2(2) + 5, or 9;

For working 8 hours, his earnings were f(28) = 2(8) + 5, or 21; and

For working 14 hours, his earnings were f(14) = 2(14) + 5, or 33

Thus, the range of this function for the days given is {9, 21, 33} (Answer D)

Hiii dont mind the answer that i put but im not sure if im right, can someone please help me?
AVprozaik [17]

Answer:

Option 4

Step-by-step explanation:

The volume of a cylinder is going to be the area of the base (which is a circle) times the height. if you have cylindrical mug, then you can use the base area×height relationship, but it won't be exact because some of the volume is going to be used for the walls of the mug itself.

Anyways:

Volume = Base Area × Height

•Base Area -> Circle = π×radius²

•Height is given as 7in.

Volume = π×(6.2in)² × 7in = 845.33975...

Volume is in units cubed (the 3rd power) which is where the in³ is from. Your closest option here looks to be the 4th choice.

Solve the following factorize and the en- equation of quadrate equation X² + 5x + 7 x = 0​
nlexa [21]

Answer:

{-12,0}

Step-by-step explanation:

first to solve this can collect like terms and add

X² +12x=0

and solve it by factorization method

X² +12x=0

x(x+12)=0

it means x multiplied by x = X² then x multiplied by 12 = 12x

so this means x or (x+12) equals to zero

x=0 and (x+12)=0

x+12=0

x=-12

so the solution set is {-12,0}

but can also be done by formula method
