Identify the coordinate of the point shown on the number line. A number line from negative 30 to 10. Major tick marks are on eve

DaniilM [7]

Answer:

The coordinates of the point P is -3

Please see attached number line

Step-by-step explanation:

The given information are;

The length of the given number line = The line extends from -30 to +10

The location of major tick marks = Every ten numbers

The location of minor tick marks = Every number

The location of the point P = Three ticks to the left of 0

Therefore, the coordinates of the point P = -3

Solve by completing the square: x^2+15=8x

Nataly_w [17]

<span>x^2+15=8x
</span><span>x^2-8x=-15
x^2 - 2 (x)(4) =-15
adding 16 on both sides
</span>x^2 - 2 (x)(4) +16=-15+16
x^2 - 2 (x)(4) + 4^2= 1

(x-4)^2=1

taking square root on bothsides x-4 = +-1
so x-4=1 or x-4=-1
x-5 or x=3

5/7m- 1/7=9/14 Can someone please tell me what "m" is?

yanalaym [24]

Answer(s):

$m=1.1, m=11/10,m=1\frac{1}{10}$

Step-by-step explanation:

Start with:

$\frac{5}{7} m-\frac{1}{7} =\frac{9}{14}$

Let's add $\frac{1}{7}$ to both sides of the equation.

$\frac{5}{7} m=\frac{9}{14}+\frac{1}{7}$

Add $\frac{9}{14}+\frac{1}{7}$ by multiplying $\frac{1}{7}$ by $\frac{2}{2}$ to get a common denominator.

$\frac{9}{14}+\frac{2}{14}$

Add:

$\frac{11}{14}$

Now back to our main equation:

$\frac{5}{7}m=\frac{11}{14}$

Let's rewrite to make finding the cross product easier.

$m$ × $\frac{5}{7} =\frac{11}{14}$

Find the cross product:

$m$ × $70=77$

Rewrite.

$70m=77$

Divide by the coefficient of $m$ , which is $70$ .

$m=1.1$
