Find an equation in point-slope for the line having the slope m m = - 6 and containing the point (8,6)
Answer:
y-6 = -6(x-8)
Step-by-step explanation:
Here, we want to get the equation of the line in point-slope form
The point slope form is;
y-y1 = m(x-x1)
(x1,y1) represents the slope
We have this as ;
y-6 = -6(x-8)

Answer:
formula
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Step-by-step explanation:
choose two point of A, let k(-2, -3) and l(1, 3)
[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]
choose two point of B, let c(0, 5) and d(5, 0)
[tex]m = \frac{5 - 0}{0 - 5} = \frac{5}{ - 5} = - 1[/tex]
Hence the gradient of A is
[tex] \frac{1}{2} [/tex]
and B is -1

Michael deposited $300 in a savings
account that paid 6% simple interest.
He made no deposits or withdrawals
for 5 years.
a. How much interest did Michael
earn in 5 years?
b. How much money was in Michael's
account at the end of 5 years?
Answer:
$401.47
Step-by-step explanation:
1st year: 300+6%=318
2nd Year: 318+6%= 337.08
3rd Year: 337.08+6%= 357.30
4th Year: 357.30+6%= 378.74
5th Year= 378.74+6%= 401.47
Answer:
If the simple interest is 6% then A is $90.00 and B is $390.00.
Step-by-step explanation:
Find the interest on naira 40000.00 for 2 years at 20% per annum compound interest. Please I need the answer ASAP
Given:
Principal value = 40000
Rate of compounded interest = 20%
Time = 2 years
To find:
The interest.
Solution:
Formula for amount is
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, P is principal, r is rate of interest and t is time in years.
Putting the given values, we get
[tex]A=40000\left(1+\dfrac{20}{100}\right)^2[/tex]
[tex]A=40000\left(1+\dfrac{1}{5}\right)^2[/tex]
[tex]A=40000\left(\dfrac{6}{5}\right)^2[/tex]
[tex]A=40000\left(\dfrac{36}{25}\right)[/tex]
[tex]A=57600[/tex]
Now, the formula for interest is
[tex]I=A-P[/tex]
[tex]I=57600-40000[/tex]
[tex]I=17600[/tex]
Therefore, the amount of compound interest is 17,600.

The length of AB is four times the length of BC.
AC = 75 cm.
Work out the length of AB.
Answer:
Let length of bc be x cm
Thus, ab=4x
ab+bc=ac
4x+x=75
5x=75
x=75/5
x=15
Therefore, ab=x=15cm
bc=4x=60cm

HELP OMG HELP!!!!
Answer:
Step-by-step explanation:
Answer:x = 14
My Step-by-step explanation:
Turn the problem around by switching around the division:
238/x=17 means 238/17=x so x = 14.
WHAT WOULD THIS BE!?!!!!!
Answer:
B 9
Step-by-step explanation:
Use the rule of exponents for a division. To divide two powers with the same base, write the same base and subtract the exponents.
[tex] \dfrac{a^m}{a^n} = a^{m - n} [/tex]
Now do it with your numbers.
[tex] \dfrac{3^4}{3^2} = 3^{4 - 2} = 3^2 = 3 \times 3 = 9 [/tex]
Answer: B 9

0.9(x-20)=830
What does x equal?
Answer:
x = [tex]942\frac{2}{9}[/tex]
Step-by-step explanation:
0.9 ( x - 20) = 830
0.9x - 18 = 830
0.9x = 848
9x = 8480
x = [tex]942\frac{2}{9}[/tex]

x= 5°
because GEF AND DEG ARE EQUAL
THEN DEF= 2 * GEF
DEF = (9*5)*2=90
DEF= 90°

Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)

The circumference of a circle is 32 cm which is the closest to the diameter
Given:
The circumference of a circle is 32 cm.
To find:
The diameter of the circle.
Solution:
We know that, circumference of a circle is
[tex]C=2\pi r[/tex]
It can be written as
[tex]C=\pi d[/tex] [tex][\because d=2r][/tex]
Where, r is the radius of the circle and d is the diameter of the circle.
The circumference of a circle is 32 cm.
[tex]32=\pi d[/tex]
[tex]\dfrac{32}{\pi}=d[/tex]
[tex]\dfrac{32}{3.14}=d[/tex]
[tex]d\approx 10.19[/tex]
Therefore, the diameter of the circle is about 10.19 cm.

Janet's car insurance payment decreases by $30 each year. Which expressions represent the total change in her payment, in dollars, after 4 years?
Answer:
The change after five years is equal to -$100
Step-by-step explanation:
If the insurance payment is equal to P = N dollars, where P is a real number, we know that after one year, the payment decreaces by $20, so the new payment is:
P = N - $20
Then, after 5 years, the $20 dollars are discounted five times, so the payment will be:
P = N -5*$20 = N - $100
Then the total change after 5 years is equal to those $100 that are being subtracted in the last equation.
