Find the equation of line (use exact numbers)​

Mathematics
1 answer:
maw [93]3 years ago

Answer:

y=3x+3

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( \frac{rise}{run} ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

y=mx+3

Now find the slope. Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3

The slope is 3. Insert this value:

y=3x+3

:Done

Answer:

x=1

Z=35.4965

assuming you want y to be the height, y=5.916

Step-by-step explanation:

x/height=height/35

35x=y^2

using Pythagorean theorem

y^2+x^2=6^2

y^2+35^2=z^2

substituting for y^2

35x+x^2=6^2

x^2+35x-36=0

(x+36)(x-1)=0

x=1

y^2+x^2=6^2

substitute

y^2+1=36

y^2=35

y=5.916

y^2+35^2=z^2

substitute

35+1225=z^2

z^2=1260

z=35.4965

Solve the system of equations:
PolarNik [594]

Answer:

D.(-1,-5) and (5,7)

Step-by-step explanation:

I used a graphing tool to graph the two equations together. When graphed, the equations intercept (5,7) and (-1,-5). Therefore, they are the solutions to the system.

Option D should be the correct answer.
