XZ = square root (16^3 + 63^2)
XZ = square root (256 + 3969)
XZ = square root (4225)
XZ = 65

sin(Z) = 16 / 65

answer is A. 16/65

the coordinates of points a and b are (2,4) and (-2,-4) respectively. what is the slope of the line that connects the two points

solmaris [256]

we are given two points as

(2,4) and (-2,-4)

Let's assume

first point as (x1,y1)=(2,4)

so, x1=2 and y1=4

Second point as (x2,y2)=(-2,-4)

so, x2=-2 and y2=-4

now, we can use slope formula

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{-4-4}{-2-2}$

now, we can simplify it

$m=2$

so, slope is 2 ..................Answer

5y-3y+1=7<br><br> solve for y

Juli2301 [7.4K]

Answer:

y=3

Step-by-step explanation:

Let's solve your equation step-by-step.

5y−3y+1=7

Step 1: Simplify both sides of the equation.

5y−3y+1=7

5y+−3y+1=7

(5y+−3y)+(1)=7(Combine Like Terms)

2y+1=7

Step 2: Subtract 1 from both sides.

2y+1−1=7−1

2y=6

Step 3: Divide both sides by 2.

2y /2 = 6 /2

y=3

Answer:

(y+1)= -3(x-3)

Step-by-step explanation:

Use Point-Slope Formula

$(y-y_{1} )=m(x-x_{1} )$

Substitute

$(y+1) =-3(x-3)$
