What is y =2x 5 in standard form?

Answers

Answer 1

Answer: To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.Ax+By=CA⁢x+B⁢y=CMove 2x2⁢xto the left side of the equation because it contains a variable.y−2x=5y-2⁢x=5Amust be positive, so multiply both sides of the equation by −1−1⋅(y−2x)=−1⋅5-1⋅y-2⁢x=-1⋅5Simplify the left side of the equation.Multiply −1-1by y−2xy-2⁢xto get −1(y−2x)-1⁢y-2⁢x.−1(y−2x)=−1⋅5-1⁢y-2⁢x=-1⋅5Apply the distributive property.−1y−1(−2x)=−1⋅5-1⁢y-1⁢-2⁢x=-1⋅5Simplify.Rewrite −1y-1⁢yas −y-⁢y.−y−1(−2x)=−1⋅5-⁢y-1⁢-2⁢x=-1⋅5Multiply −2-2by −1-1to get 22.−y+2x=−1⋅5-⁢y+2⁢x=-1⋅5Reorder −y-⁢yand 2x2⁢x.2x−y=−1⋅52⁢x-⁢y=-1⋅52x−y=−1⋅52⁢x-⁢y=-1⋅52x−y=−1⋅52⁢x-⁢y=-1⋅5Multiply −1-1by 55to get −5-5.2x−y=−52⁢x-⁢y=-5

Given that D(x) = 2x, select all of the following that are true statements. a- D(x) is a function,
b- xis the dependent variable,
c- D(6) = 3,
d- D(x) is a direct variation,
e- D(x) is a rule for the set of points (5, 10), (6, 12) and (-2, -4).

Answers

For D (x) = 2 x:
- x is the independent variable,
- D ( 6 ) = 2 · 6 = 12.
10 = 2 · 5, 12 = 2 · 9, - 4 = 2 · ( - 2 ).
True statements are:
A ) D ( x ) is a function.
D ) D ( x )is a direct variation.
E ) D ( x ) is arule for the set of points ( 5, 10), ( 6, 12 )and ( -2, - 4 ).

Bryan is buying notebooks and pens at an office supply store. Notebooks cost $3.59 and pens cost $1.49. He can spend up to $13 on these items. Let x represent the number of notebooks. Let y represent the number of pens. Enter an inequality that represents the situation.

Answers

Answer:if the notebooks cost 3.59 and pens cost 1.49, with x representing the notebooks and y representing the number of pens and an amount of $13, the inequality would be written as 3.59x+1.49y13
