Answer:
i = 7.5
Step-by-step explanation:
(5-3i)+(10+5i)
(5+10)+(5i-3i)
15+2i
15=-2i
15/2-i
7.5=i
Answer:
y = ⁷/5x + 34/5
Or
y = 1.4x + 6.8
Step-by-step explanation:
To find the equation of the line in the slope-intercept form, y = mx + b, we have to determine the value of:
Slope (m) = change in y/change in x
y-intercept (b) = the y-coordinate of the point where the y-axis is intercepted by the line
Using the two points indicated in the line, (-7, -3) and (-2, 4),
Slope (m) = (4 - (-3))/(-2 - (-7)) = 7/5
m = ⁷/5
To find b, substitute m = ⁷/5 and (x, y) = (-2, 4) into y = mx + b
4 = ⁷/5(-2) + b
4 = -14/5 + b
4 + 14/5 = b
(20 + 14)/5 = b
34/5 = b
b = 34/5
To write the equation, substitute m = ⁷/5 and b = 34/5 into y = mx + b
y = ⁷/5x + 34/5
Or
y = 1.4x + 6.8
So, our friendly number will be 300: it's only two numbers away from 298!
We multiply 300 by 6: it's 1800. (3*6=18, and the 0s we can just add at the end)
now we only need to subtract those two numbers (mupliplied by 6): so we subtract 12.
the result will be 1800-12=1788.
Ax+By+C=0. Standard form of a linear equation.
Use C= (B/2)^2. To complete the square.
D=RxT. Distance = (Rate)(Time
y = mx + b. Slope-intercept form ( easy to graph)
Answer:
Answer=B
Step-by-step explanation:
when something reflects across the y-axis it's value of x change it's sign so,
points KLM will change to:
K(1,3) to (-1,3)
L(3,4) to (-3,4)
M(4,1) to (-4,1)
this all goes with the triangle in answer B
