Answer:
x = -2
Step-by-step explanation:
y = -3x + 2.5
if y = 8.5 then:
8.5 = -3x + 2.5
-3x = 6
x = -2
Answer:
Step-by-step explanation:
12) The amount of the initial deposit is $1000
13) the slope is (y2 - y1)/(x2 - x1)
Slope = (4000 - 3000)/(6 - 4)
Slope = 1000/2 = 500
The y intercept is the value of y when x is zero. Therefore,
y intercept = 1000.
14) The equation of a straight line represented in the slope intercept form is
y = mx + c
Where
m represents slope
c represents intercept
Therefore the equation is
y = 500x + 1000
15) The slope represents rate of change in the amount saved with respect to time in months.
Oven tray: 600 mm by 500 mm
cake tin: 25 cm in diameter
convert mm to cm.
1 cm = 10 mm
600mm * 1cm/10mm = 60cm
500mm * 1cm/10mm = 50cm
Area of oven tray = 60cm * 50cm = 3,000 cm²
Area of cake tin = 3.14 * (25cm/2)² = 3.14 * (12.5cm)² = 3.14 * 156.25cm² = 490.625 cm²
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins can fit on the oven tray at one time.
Answer:
N=0.019666a-0.983284 or
A = 50.85n + 50
Step-by-step explanation:
Let's solve for n.
a = 50 + 50.85n
Step 1: Flip the equation.
50.85n + 50 = a
Step 2: Add -50 to both sides.
50.85n+50+-50=a+-50
50.85n n = a - 50
Step 3: Divide both sides by 50.85.
50.85n
50.85
=
a-50
50.85
n=0.019666a-0.983284
Let's solve for a.
a = 50 + 50.85n
