Answer:

-x + -13

Step-by-step explanation:

Rewrite: 5(x – 4) + 3x – 9x + 7

Step 1: 5(x + –4) + 3x + –9x + 7

Step 2: 5x + -20 + 3x + –9x + 7

Step 3: 5x + 3x + –9x + -20 + 7

Step 4: -1x + -13

Step 5: -x + -13

Find the value of c that completes the square
PilotLPTM [1.2K]

Answer:

The value of c that completes the square  x^2+2x+c is 1

Step-by-step explanation:

We need to find the value of c that completes the square  x^2+2x+c

The formula used will be: a^2+2ab+b^2=(a+b)^2

In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,

2(x)(1) = 2x

so, c= 1

Solving:

x^2+2x+c\\=x^2+2(x)(1)+(1)^2-(1)^2\\=(x+1)^2-1

So, the value of c that completes the square  x^2+2x+c is 1

What is the exact area of the following circle?
pychu [463]

Answer:

56.25 pi  cm^2

Step-by-step explanation:

To find the area of the circle,

we use the formula

A = pi r^2, where r is the radius

We know the diameter is 15 so we can find the  radius from

r = d/2  where d is the diameter

r = 15/2

A = pi ( 15/2) ^2

A = pi ( 225/4)

A = 56.25 pi  cm^2

Consider the following linear equation.y = -1-Step 1 of 2: Determine the slope and the y-intercept (entered as an ordered pair)
Dmitriy789 [7]

Recall that a slope-intercept form of a linear equation is

\begin{gathered} y=mx+b \\ \text{where} \\ m\text{ is the slope} \\ b\text{ is the y-intercept} \end{gathered}

Rearrange the given so that it follows that slope intercept form

\begin{gathered} y=-1-\frac{2}{5}x\Longrightarrow y=-\frac{2}{5}x-1 \\  \\ \text{Now that it is in the slope intercept form} \\ y=-\frac{2}{5}x-1 \\ \text{we can determine that the slope is } \\ m=-\frac{2}{5} \\ \text{and the y-intercept is} \\ b=-1 \end{gathered}

The y-intercept is the value for which the linear function crosses the y-axis, this is when the value of x is equal to zero. The ordered pair therefore of the y-intercept is (0,-1).
