Solve the equation for all values of x: (x+1)^2=-49

Mathematics
1 answer:
Kazeer [188]4 years ago
6 0

Answer:

Values for x = -1 + 7i  and -1 - 7i

Step-by-step explanation:

we have an equation,

(x+1)^2 = -49

We need to solve this equation for all values of x:

(x+1)^2 = - 49

Taking square root both sides

√((x +1)^2) = √-49

x + 1 = ± 7i

Subtract both sides by 1

x = -1 ± 7i

Hence we get two values for x = -1 + 7i  and -1 - 7i

What is the image of (6,−3) after a dilation by a scale factor of 1/3 centered at the origin?
attashe74 [19]

Answer:

(2,-1)

Step-by-step explanation:

Multiply everything by 1/3:

6*1/3=2

-3*1/3=-1

This makes it smaller, so you know what the dilation is.

determine the area of a trapezoid the length of the midline of 14 centimeters and the length of the height of 8 centimeters
emmainna [20.7K]

Answer:

Area = 112cm^2

Step-by-step explanation:

Area = (a + b)*h / 2

M = (a + b) / 2

14 = (a + b) /

2*14 = a + b

28 = a + b

Area = 28*8 / 2

Area = 112 cm^2

If a = b and 1/x + 1/a = 1/b then x =
seraphim [82]
1/x+1/a=1/a
minus 1/a from both sides
1/x=0
false
let's try a differnt way
1/x+1/a=1/a
times both sides by xa
a+x=x
minus x from both sides
a=0
???
1/0 is undefined
this creates problems

Find the distance between each pair of parallel line<br>y=x-6 and y=x+8
myrzilka [38]
Both these lines are linear and have the same slope, just different y-intercepts. This means one line is shifted higher than the other. y=x+8 is 14 units higher than y=x-6. The answer to you question therefore is 14 units!
