Answer:
R
Step-by-step explanation:
E is congruent to R because of angle stuff
Answer:
Ann us correct. It's a quadratic function.
Step-by-step explanation:
Given equation is,
y = 3x(x - 7)
By converting this equation into the standard quadratic equation,
y = 3x² - 21x
Highest exponent of the polynomial equation is 2 (Exponent of highest degree variable x²). This decides that the given function is a quadratic function.
Therefore, Ann is correct. It's a quadratic function.
The slope-intercept form of the equation of a straight line is y=mx+b, where m is the slope and b is the y-coordinate of the y-intercept.
If the given slope is -1/2, then this equation becomes y = (-1/2)x + b.
You do not say that b=1.
But if we let b=1, then the equation becomes y = (-1/2)x + 1.
Answer <u>(assuming it can be in slope-intercept form): </u>
y = x - 5
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula, 
, and substitute the x and y values of the given points into it. Then, solve:
2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or 
. Substitute 
, 
, and 
for real values.
Since represents the slope, substitute 1 for it. Since and represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.
