Yes 5,4 is y=x-1 actually anything can be those symbols as long as they add up to the Equation
B is the correct answer because each value of y only own one x. Hope this helps!
The answer for this would be 4 times 11 that would equal 44.
Answer:
Step-by-step explanation:
3C + 8T = 58 ----- (eq1)
5C + 2T = 23 ------(eq2)
Multiply equation (1) by 5 and equation (2) by 3
15C + 40T = 290 -----(eq3)
15C + 6T = 69 ----------(eq4)
Subtract equation (4) from (3)
34T = 221
T = 221/34
T = $6.5
Therefore 1 Table will cost $6 and 5 cents
Solve for (C) in equation (1)
3C + 8T = 58
3C + 8(6.5) = 58
3C + 52 = 58
3C = 58-52
3C = 6
C = 6/3
C = $2
1 Chair will cost $2
Answer:
y=-2x-3
Step-by-step explanation:
Since our equation is in standard form Ax+By=C we must first manipulate the equation so that we have it in the slope-intercept form such that y=mx+b. Therefore:
Therefore, our slope is 1/2 and our y-intercept is 2. Now in order to determine a perpendicular line to the one stated above we must then get the negative inverse of our slope meaning 
(negative reciprocal). Now we must use the point slope formula:
Where m is the slope, x1 is -2 and y1 is 1 (because of the ordered pair given). And so:
Therefore, the line that is perpendicular to -x+2y=4 is y=-2x-3.
