For this case we have the following equation:

$-7x-3 = 2-7x-5$

Rewriting the right side of the equation we have:

$-7x-3 = -7x-3$

This is equivalent to having a system of equations of the form:

$y = -7x-3$

Since both equations are equal, then the lines are cut into infinite points.

Therefore, the system has infinite solutions.

Answer:

The equation has infinite solutions.

Which of the following points lies on the circle whose center is at the origin and whose radius is 10?

Naddik [55]

Since the standard form of the circle is:

(x-h)^2+(y-k)^2=r^2, and (h,k)=(0,0) and r=10 so we have:

x^2+y^2=100 Looking at the points you have:

(√10, 0) does not work as (√10)^2+0^2=10+0=10

(0, 2√5) does not work as 0^2+(2√5)^2=0+20=20

(5√2, 5√2) works as (5√2)^2+(5√2)^2=50+50=100

Find the circumference of the circle and round to the nearest tenth

Ede4ka [16]

Step-by-step explanation:

Circumference of Circle =

$2\pi \: r$

given d = 19.4mi

r = 1/2d

= 1/2 x 19.4

= 9.7mi

Circumference of Circle =

$2\pi(9.7) \\ = 19.4\pi \\ = 60.9mi \: (nearest \: tenth)$

If 8 is added to twice a number and this sum is multiplied by 5, the result is the same as if the number is multiplied by negat

Naily [24]

(8+2x) -> If 8 is added to twice a number (x)
5*(8+2x) -> and this sum is multiplied by 5
5*(8+2x)=x*(-28)+2 -><span>the result is the same as if the number is multiplied by negative −28 and 2 is added to the product.

Simplifying the equations on both sides would give
40+10x=-28x+2 transpose -28 to the left side and 40 to the right side
28x+10x=2-40
38x=-38
x=-1</span>

Urgent!

Doss [256]

Answer:

${(1 - 2x)}^{p} = 1 + ( - 2x)p + \frac{1}{2!} p(p - 1) {( - 2x)}^{2} + ... \\ \frac{4}{2!} p(p - 1) = 40 \\ p(p - 1) = 20 \\ {p}^{2} - p = 20 \\ {p}^{2} - p - 20 = 0\\ ( p - 5)(p + 4) = 0\\ p = 5 \: or \: p = - 4 \\ \because \: p > 0 \\ \therefore \: p = 5$ Apply the binomial expansion...
