Fetermine the slope and the y intervept. Then use the slop and the y intercept to graph the equation by hand.

1 answer:

3 0

Y=(-1/4)x -1

The slope is the coefficient of x, that means slope = -1/4
To find y-intercept, just replace x by zero. y =(-1/4) (0) -1
and y-intercept = -1

How do you find the square root of a negative number? Explain the process

IrinaK [193]

Answer:

A. $\sqrt{-64}$ = 8i

B. 8i + 5i = 13i

C. 8i - 5i = 3i

D. 8i x 5i = -40

Step-by-step explanation:

A. The square root of any negative number would lead to a complex number. Complex numbers are number which consist a complex part denoted by i.

-1 = $i^{2}$

$\sqrt{-1}$ = $\sqrt{i^{2} }$ = i

Example: 1. What is the square root of -64?

square root of -64 = $\sqrt{-64}$

= $\sqrt{-1 *64}$

= $\sqrt{-1}$ x $\sqrt{64}$

= i x 8

= 8i

$\sqrt{-64}$ = 8i

2. find the square root of -25.

$\sqrt{-25}$ = $\sqrt{-1*25}$

= 5i

B. To add two complex numbers, they are considered as algebraic expressions.

Example, the sum of 8i and 5i can be determined as;

8i + 5i = 13i

C. To add two complex numbers, they are considered as algebraic expressions.

Example, the subtraction of 8i and 5i can be determined as;

8i - 5i = 3i

D. To multiply two complex numbers, the complex part is considered.

Example, determine the product of 8i and 5i.

8i x 5i = 8 x 5 x i x i

= 40 $i^{2}$

= -40 (∵ $i^{2}$ = -1)

8i x 5i = -40

How do I find the measure of angle 1 and 2

Dvinal [7]

Angle 1 is a vertical angle in relation to the given angle, 117°, so it has the same measure.

Angle 2 is a corresponding angle to angle 1 where the transversal crosses parallel lines, so it has the same measure. (It is also an alternate exterior angle with respect to 117°, so has the same measure.)

∠1 = ∠2 = 117°
