Answer:

(D) On a graph, plot the line y = −x + 1, which has y-intercept = 1 and slope = −1, and y = 2x + 4, which has y-intercept = 4 and slope = 2, and write the coordinates of the point of intersection of the two lines as the solution.

Answer:

d. y-3 = f(x)

Step-by-step explanation:

we don't know what f(x) is. but we can see that the red line is 3 units above the black line. so we are adding 3 to whatever f(x) is. so the red line should have the equation

y = f(x) +3

subtract 3 from both sides

y-3 = f(x)

Write slope intercept equation passing through (-5,0) and (0,4/5)

pav-90 [236]

First find the slope by calculating rise (change in x) over run (change in y).

(4/5)-0/0-(-5)

(4/5)/5=0.16

The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.

Then plug this into y=mx+b where m is slope andb is y intercept.

Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5

Find equation of the circle in standard form for the given center (h,k) and radius (r) : (h,k)=( -3/5 , -4/5 ), r=1

svp [43]

The center is at (h,k) so we have the folowing.
$(x - (-\frac{3}{5}))^2 + (x - (-\frac{4}{5}))^2$

1. What is the value of x? Show all of your work.

AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117

Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
$\sqrt{81} = 9$
Therefore AB is 9 cms.
