Answer:

x= -1

Step-by-step explanation:

firstly group the like terms

4-6=2x

-2=2x

divide both sides by 2

-2/2=2x/2

-1=x

therefore x is -1

Answer:

$x=-1$

Step-by-step explanation:

$4=6+2x$

Flip the equation:

$2x+6=4$

Subtract 6 from both sides:

$3x+6-6=4-6$

$2x=-2$

Divide both sides by 2:

$2x/2=-2/2$

$x=-1$

The Vertex of a parabola is at (8-1), and it's why intercept is negative 17, which function represents the parabola

suter [353]

Answer:

The function is equal to $y=-(1/4)(x-8)^{2}-1$

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

$y=a(x-h)^{2}+k$

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(8,-1)

substitute

$y=a(x-8)^{2}-1$

<u><em>Find the value of a</em></u>

Remember that we have the y-intercept

The y-intercept is the point (0,-17)

substitute

x=0,y=-17

$-17=a(0-8)^{2}-1$

$-17=64a-1$

$64a=-17+1$

$64a=-16$

$a=-16/64$

$a=-1/4$

therefore

The function is equal to

$y=-(1/4)(x-8)^{2}-1$

A stock was priced at $12 3/8 per share. It rose in price by $3 1/4 per share. What was its new price?

lubasha [3.4K]

Option A

The new price is $ $15 \frac{5}{8}$

<h3><u>Solution:</u></h3>

Given that, a stock was priced at $ $12 \frac{3}{8}$ per share.

It rose in price by $ $3 \frac{1}{4}$ per share.

New price = old price + rise in price

Thus to find out the new price, we have to add old price and rise in price

$\text { So, new price }=\$ 12 \frac{3}{8}+\$ 3 \frac{1}{4}$

$\text { New price }=\frac{12 \times 8+3}{8}+\frac{3 \times 4+1}{4}$

On solving we get,

$\text { New price }=\frac{96+3}{8}+\frac{12+1}{4}$

$\begin{array}{l}{\text { New price }=\frac{99}{8}+\frac{13}{4}=\frac{99+26}{8}} \\\\ {\text { New price }=\frac{125}{8}}\end{array}$

On converting to mixed fraction,

$\begin{array}{l}{\text { New price }=\frac{120+5}{8}} \\\\ {\text { New price }=15 \frac{5}{8}}\end{array}$

Hence, the new price is $15 \frac{5}{8}$ , so option A is correct.

Which set of numbers shows all factors of 18

Alexxx [7]

Answer:

Step-by-step explanation: Factors of 18: The square root of 18 is 4.2426, rounded down to the closest whole number is 4. Testing the integer values 1 through 4 for division into 18 with a 0 remainder we get these factor pairs: (1 and 18), (2 and 9), (3 and 6). The factors of 18 are 1, 2, 3, 6, 9, 18.
