Answer:

\boxed {10,000,000}

Step-by-step explanation:

Solve the following problem:

(-10^{-2})^{-4}

-Calculate -10 to the power of -2:

(-10^{-2})^{-4}

(-\frac{1}{100})^{-4}

-Calculate -\frac{1}{100} to the power of -4:

(-\frac{1}{100})^{-4}

\boxed {10,000,000}

Find the percent of change from the first value to the second. 20 ; 80
Lemur [1.5K]

Answer:

Percent Change Formula: [(new - old)/old] * 100

Step-by-step explanation:

New - old

80 - 20 = 60

Difference between new - old divided by old

60/20 = 3

Previous quotient times 100

3*100 = 300

Percent Change is 300%

Check your answer

300% of 20 is 60

20 + 60 = 80

The points (1, 3) and (−3, 7) lie on a line. where does the line cross the x-axis?
Anastasy [175]
First, we find the equation of the line...

(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1

y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
 y = -x + 4

Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x

y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)

Help with geometry..need help...if any of you is good with geometry
aev [14]

Answer: For the first image, D will be the correct answer. For the second image, A will be the correct answer.

Step-by-step explanation:

The first image has a quite simple answer because translating the shape just means moving every point in the direction given according to some many units. In this case, we would be translating points A(-4,3), B(-3,1), and C(-1,2) 5 units right and 5 units down to get us the prime points of A'(1,-2), B'(2,-4), C'(4,-3).

In the second image, a reflection just describes a flip over some line, known as the line of reflection. We change the point's signs depending on the line of symmetry we are given when reflecting (in this case, the y axis). Reflecting the trapezoid over the y axis will result in a change of signs of the x values of the given points. Point A of the trapezoid is located on coordinate (-2,2), after the reflection, it will be located on point (2,2). Points B will reflect from point (-1,2) to point (1,2). Point C will reflect from (-1,1) to (1,1). Finally, point D will reflect from point (-3,1) to (3,1). After this reflection, we have to perform the same one except only the y values of our coordinates will change because we are reflecting over the x axis. After you graph the trapezoid from the previous reflection, do the same thing by just changing the y values of the coordinates to get your desired image.
