The points (1, 5) and (0, –2) fall on a particular line. What is its equation in slope-intercept form?

Hunter-Best [27]

Answer:

y = 7x - 2

Step-by-step explanation:

first we need the slope of the line.

the slope is expressed a the ratio (y coordinate change / x coordinate change) when we go from one point on the line to another.

so, let's say we go from (0, -2) to (1, 5), we see

x changes by +1 (from 0 to 1).

y changes by +7 (from -2 to 5)

so the slope is +7/+1 = 7

the slope-intercept form is in general

y = ax + b

a being the slope, b being the y-intercept (the y-value for x = 0).

the point (0, -2) gives us therefore the y-intercept directly : -2.

by using the already established slope and the point (0, -2) for the y-intercept the equation of our line is

y = 7x - 2

Which statement regarding the function y=sin(x) is true?

REY [17]

<h2>Answer:</h2>

c. Reflection over either the x-axis or y-axis will change the graph

<h2>Step-by-step explanation:</h2><h3>a. Reflection over the y-axis will not change the graph since sine is an even function.</h3>

This is false because $y=sin(x)$ is an odd function, not an even one. This means that $sin(-x)=-sin(x)$ , and a reflection over the y-axis will change the graph.

This is false because we said that $sin(-x)=-sin(x)$

<h3>c. Reflection over either the x-axis or y-axis will change the graph</h3>

This is true. Since $sin(x)$ is an odd function, then reflection over either the x-axis or y-axis will change the graph as we said in a. So, for $f(x)$ :

<u>REFLEXION IN THE X-AXIS:</u>

$h(x)=-f(x)$

<u>REFLEXION IN THE Y-AXIS:</u>

$h(x)=f(-x)$

False by the same explanation as b.

The measure of the angles

Gre4nikov [31]

Answer: a = 150
b = 30

Remember: supplementary angles always add up to 180 degrees. Therefore, using this information, you can easily form your equation.

Form your equation. Since a is five times b, a = 5b.
5b + b = 180 Combine like terms
6b = 180 Divide by 6 to both sides
b = 30 Answer!

Substitute (30) for b in a = 5b to find a.
a = 5(30) Simplify
a = 150 Answer!

Need help asap please 35 points

SashulF [63]

Answer:

Step-by-step explanation:

because line BC divides line DA and line AE into parts with the same ratio to each other (since BC is parallel to DE). This means that (42/21)*17 will give us the length of AB, when we do so, we get 34 as the length of AB.
