The answer is not A because it less than or equal to and 1 is = 1.
The answer is D because -5 is less than 1 and its not equal to 1.
Answer:
Answer is 4x+15
Step-by-step explanation:
4(6−2x)−3(3−4x)
Distribute:
=(4)(6)+(4)(−2x)+(−3)(3)+(−3)(−4x)
=24+−8x+−9+12x
Combine Like Terms:
=24+−8x+−9+12x
=(−8x+12x)+(24+−9)
=4x+15
Answer:
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y-intercept. y and x are the y and x values of any point respectively.
The information we have:
y = 6
x = -1
m = -3
6 = -3*-1 + b
6 = 3 + b
b = 3
So now we know that m = -3 and b = 3
y and x were 6 and -1 in this case but we need an equation that works for any point on the line so we can keep y and x just as it is (variables, not numbers).
The final equation is:
y = -3x + 3
Testing my knowledge on this one.
A - when doing a 180 degree rotation, the coordinates (x,y) would become
(-x,-y), in other words, the inverse of the numbers in the x and y
places, (-1,2)->(1,-2)
B - when reflecting over the x axis, only the y coordinate inverts, (x,y) becomes (x,-y), (1,-2)->(1,2)
I think it's B i jope that helps but here is some extra info if you like reading(lol)
Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C. Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b.
In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.
<span><span>y=mx+b</span><span>y=mx+b</span></span>
Where m is the slope and b is the y-intercept.
Example
Graph the equation
<span><span>y−2x=1</span><span>y−2x=1</span></span>
rewrite in slope-intercept form
<span><span>y=2x+1</span><span>y=2x+1</span></span>
Identify the slope and the y-intercept
m = 2 and b = 1
Plot the point corresponding to the y-intercept, (0,1)
The m-value, the slope, tells us that for each step to the right on the x-axis we move 2 steps upwards on the y-axis (since m = 2)
