Y = 5-3x, Darw the graph of the function. Use the find the value of y when x=4, and when x = 5​
stellarik [79]

Answer:

The line passes through (4, -7) and (5, -10).

Step-by-step explanation:

When x = 4, y = 5 - 3(4), or 5 - 12, or -7.  Thus the point (4, -7) lies on the graph.  Similarly y = 5 - 3(5) = -10 when x  = 5.  Thus, the line also goes through (5, -10).  Plot these two points and draw a line through them.  Doing this will result in the desired graph.

4) Solve each pair of simultaneous equations.
Mkey [24]
4) a. x+y=1–(1)
y=2x-8—(2)
(2) into (1)
x+(2x-8)=1
3x-8=1
3x=1+8
x=9/3
x=3—(3)
(3) into (2)
y=2(3)-8
y=-2

ans x=3, y=-2

b. x+y=19—(1)
y=5x+1—(2)

(2) into (1)

x+(5x+1)=19
6x+1=19
6x=19-1
x=18/6
x=3—(3)

(3) into (2)

y=5(3)+1
y=16

ans x=3, y=16

c.x+y=-2—(1)
y=x-10—(2)

(2) into (1)

x+(x-10)=-2
2x-10=-2
2x=-2+10
x=8/2
x=4–(3)

(3) into (2)
y=4-10
y=-6

ans x=4, y=-6


5) 3x=y—(1)
x=y-16–(2)

(2) into (1)

3(y-16)=y
3y-48=y
2y=48
y=48/2
y=24–(3)

(3) into (2)

x=24-16
x=8

ans x=8, y=24

Solve -6.5m+14.3&lt;-22.75
Tom [10]

Step-by-step explanation:

-6.5m + 14.3 < -22.75

-6.5m < -37.05

6.5m > 37.05

m > 37.05/6.5 = 5.7

m > 5.7 for this inequality to be true
