Writing a Linear Equation

Mathematics
1 answer:
d1i1m1o1n [39]3 years ago
6 0

Answer:

Step-by-step explanation:

First find the slope of the line that passes through the points (-5,0) and (-1, -8).  Notice how x increases 4 units from -5 to -1 and y decreases 8 units.

Thus, the slope of this line is m = rise / run = -8/4, or m = -2.

Another way to look at this:

       change in y      - 8 - 0

m = -------------------- = ------------ = -2

        change in x       -1 - (-5)

Please note:   m=-1 - (-5) = 45

8 = -2 is not correct; 8 cannot equal -2.

HELP! DUE IN A FEW HOURS
Alenkasestr [34]

Answer:

Options (C) and (E).

Step-by-step explanation:

Rotation is a rigid transformation in which size and shape of the figure and image remains the same.

That means angles and sides of the triangles given in the figure will remain same after the transformations given.

Since, the given triangle has been rotated about a point Z, each rotation will share the vertex Z.

And every figure is the transformed form of the given triangle, all four triangles will be congruent.

Options (C) and (E) are the correct options.

find the common ratio r for the geometric sequence and use r to find the next three terms 5,15,45,135
Aleks04 [339]

Answer: 405


Step-by-step explanation:

ratio r for the geometric  sequence: 5, 15, 45, 135

r is a radios of a circle,

d is the Diameter

r1=5. r2=15, r3=45, r4=135, r5=?

2*r=d

so:

d1=10, d2=30, d3=90, d4= 270

now following the sequence:

r1+d1=r2       5+10=15

r2+d2=r3      15+30=45

r3+d3=r4       45+90=135

r4+d4=r5      therefore 135 + (135*2) = 135+270=405

Helppp!!! This has to be done by 8!!! And it’s 7:45!!
san4es73 [151]

Answer:

The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.

Step-by-step explanation:

When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.

If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
