Given x=-3, y=6, and z=-4<br> -15+(-x)+y=
Alexus [3.1K]

Answer:

-6

Step-by-step explanation:

We are given x=- 3 , y= 6 and z= -4.

We are also given the expression:

-15 + (-x) +y

Substitute -3 in for x and 6 in for y.

-15 + (- -3) + 6

2 negative signs creates a positive sign

-15 + (+3) +6

-15 + 3+ 6

Add -15 and 3.

(-15+3) +6

-12 +6

Add -12 and 6.  

-6

-15+(-x)+y evaluated at x= -3 and y=6 is equal to -6.

Joanna plans on hanging 3 pictures of different sizes on the wall of her staircase. She thinks it will look best if all 3 rectan
Natasha2012 [34]
In similar figures, the ratio between corresponding sides are the same.

\frac{25}{35}=\frac{35}{49}

Simplify the two to see that they are equal.
The top and bottom of the left fraction are divisible by 5.
The top and bottom of the right fraction are divisible by 7.

\frac{5}7=\frac{5}7

Of course, the dimensions of that third picture would have to be this fraction.
Let's test these answers.

\frac{5}6\neq\frac{5}7 ⇒ A is not a solution

\frac{30}{42}=\frac{5}7 ⇒ B is the solution
(divide the top and bottom by 6)

between 1995 and 2006, the population of samburg, usa(in thousands) can be modeled by f(x) = 0.35x(squared) - 2.1x+15.8 where x=
Juli2301 [7.4K]
\bf f(x)=0.35x^2-2.1x+15.8\qquad &#10;\begin{cases}&#10;x=\textit{year since 1995}\\&#10;f(x)=\textit{population amount}&#10;\end{cases}

the equation is a quadratic one, and it has a positive coefficient on the leading term, meaning, is opening upwards, so it has a "burrow" for the vertex.

the minimum or lowest point for a quadratic opening upwards is, well, the vertex point :),   the "x" value is the year, the "y" or f(x) value is the population, we're asked for the year, or the x-coordinate of the vertex

well   \bf \begin{array}{llll}&#10;f(x)=&0.35x^2&-2.1x&+15.8\\&#10;&\quad \uparrow &\quad \uparrow&\uparrow \\&#10;&\quad  a&\quad  b &c&#10;\end{array}&#10;\\\\&#10;&#10;\\\\&#10;\qquad  \textit{vertex of a parabola}\\ \quad \\&#10;\qquad &#10;&#10;\left(\boxed{-\cfrac{{{ b}}}{2{{ a}}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)
