i=\sqrt{-1}\to i^2=-1\\\\i^{15}=i^{1+14}=i^1\cdot i^{14}=i\cdot i^{2\cdot7}=i\cdot (i^2)^7=i\cdot(-1)^7=i\cdot(-1)=-i

\text{Used:}\\\\a^n\cdot a^m=a^{n+m}\\\\(a^n)^m=a^{n\cdot m}

The sum of two numbers is 58. The first number is 8 less than half the second number. Let c represent the first number. Let d re
alexandr1967 [171]

Answer: A ,C,G and H are correct statements. Look into the step by step for more understanding.

Step-by-step explanation:

To solve for this problem let's find the actually numbers.

so we know that c + d=58  and also c= 1/2d-8  

We have two systems of equations

c+d = 58

c= 1/2d - 8  

Solve for c   by substitution.  Substitute the second equation into the first one.

1/2d -8 + d = 58   Add 8 to both sides

1/2 +d = 66

3/2d =66     Divide both sides by 3/2

d=44  Now we  know the d which is the second number is 44  so subtract it from 58 to find the first number.

58 - 44 = 14  

we will represent the statements by letters from A going.

A. The equation c + d = 58 represents the sum of the two numbers

B. The equation c+d=58 represents the sentence "The first number is 8 less than half the second number."

C.The equation c= 1/2d -8 represents the relationship between the two numbers.

D. The equation  c= 1/2d - 8 represents the sum of the two numbers.

E. The number d is 14.

F. The number c  is 44.

G. The number c is 14.

H. The number  d is 44.  

Now looking at the statements, A ,C,G and H are all correct.

Analyze the solution set of the following system by
blsea [12.9K]

Answer:

The equations in the slope-intercept form

y = - 2 x + 5

y = - 2 x + 3

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

  • m is the slope of the line.
  • b is the y-intercept.

To put any equation in the slope-intercept form state y on the left side, x and the numerical term on the right side, the coefficient of y must be 1.

Let us do that with the given equations

∵ 2x + y = 5

→ Subtract 2x from both sides to move x to the right sides

∴ 2x - 2x + y = 5 - 2x

∴ y = 5 - 2x

→ Switch 5 and - 2x

∴ y = - 2x + 5

∵ 3y = 9 - 6x

→ Divide each term by 3 to make the coefficient of y = 1

∴ \frac{3y}{3}=\frac{9}{3}-\frac{6x}{3}

∴ y = 3 - 2x

→ Switch 3 and - 2x

∴ y = - 2x + 3

The equations in the slope-intercept form

y = - 2x + 5

y = - 2x + 3
