Answer:
Step-by-step explanation:
Find the slope of the line first using
(3, 4), (2, -1)
= 5
Now use y - y1 = m(x - x1) to make an equation in slope-intercept form. Plug the numbers into the formula.
y - (-1) = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11
The equation of the line in slope-intercept form would be y = 5x - 11.
Answer:
b = 2A/h
b = 6 inches
Step-by-step explanation:
Answer: in the 1% account we have $2600 and in the 6% account we have $2400.
Step-by-step explanation:
We have two amounts A and B such that:
Where A is the amount invested in the 1% earning interest account and B is the amount invested in the 6% earning interest account.
A + B = $5000,
If the interest is yearly, then we have that, after one year, the interest is:
A*(1%/100%) + B*(6%/100%) = $170
A*0.01 + B*0.06 = $170
So we have two equations:
A + B = $5000
A*0.01 + B*0.06 = $170
In the first equation we can isolate A and get:
A = $5000 - B
and replace it in the other equation:
($5000 - B)*0.01 + B*0.06 = $170
$50 + B*0.05 = $170
B*0.05 = $120
B = $120/0.05 = $2400
Then A = $5000 - $2400 = $2600.
Answer: 154
Step-by-step explanation:
The mean is calculated by adding up all the numbers and dividing by the number of observations added up.
The above can therefore be expressed as:
(88 + 55 + 99 + x) / 4 = 99
242 + x = 99 * 4
242 + x = 396
x = 396 - 242
x = 154
