work out the equation of a line which has a gradient of -2 and passes through the point (1 ,7)
Answer:
Y=-2x+9
Step-by-step explanation:
The first thing is to know the formula which is Y÷x
Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y
So it will be Y-7÷X-1 = the gradient which is - 2
So multiply both sides by X-1
So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign
Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers
Arrange the steps in the correct order to solve this trigonometric equation 2sin^2 x -sinx -1 =0 for 0 degrees is less than or equal to x is less than or equal to 90 degrees
Answer:
90°Step-by-step explanation:
Given the trigonometry equation;
[tex]2sin^2 x -sinx -1 =0[/tex]
Step 1; Let p = sin(x) to have;
[tex]2sin^2 x -sinx -1 =0\\2P^2 -P -1 =0[/tex]
Step 2: factorize the resulting quadratic equation:
[tex]2P^2 -P -1 =0\\2P^2 -2P+P -1 =0\\\2P(P-1)+1(P-1)=0\\(2P+1)(P-1) = 0\\2P + 1 = 0 \ and \ P-1 = 0\\P = -1/2 \ and \ P =1[/tex]
Step 3: Find x:
when p = 1
sin(x) = 1
[tex]x = sin^{-1}1\\x = 90^0[/tex]
also when p -1/2
sin (x) = -1/2
[tex]x = sin^{-1}-1/2\\x = -30^0\\[/tex]
[tex]x = 180-30\\x = 150^0[/tex]
Since 150° is not within the range 0<x<90, then the only solution is 90°

Graham's monthly bank statement showed the following deposits and withdrawals.
- $87.45, - $24.76, $143.87 – $17.29 $348.90
If Graham's balance in the account was $456.78 at the beginning of the month,
what was the account balance at the end of the month?
Answer:
622.27
Step-by-step explanation:
- $87.45 + (- $24.76) + (-17.29) = $-129.5
$143.87 + $348.90 = $492.77
492.77 - (-129.5) = 622.27

b. The total cost (1) after 8% sales tax is added to an item's price (p): 1.08p =
=f
Is there a proportional relationship
Answer:
No
Step-by-step explanation:
Yes, there is a proportional relationship between the total cost (f) after 8% sales tax is added and the item's price (p).
Here,
In this case, the total cost (f) is calculated by multiplying the item's price (p) by 1.08 (which is 100% + 8% sales tax in decimal form).
Mathematically, this can be represented as:
f = 1.08p
The equation shows that the total cost (f) is directly proportional to the item's price (p) with a proportionality constant of 1.08.
This means that as the item's price (p) increases, the total cost (f) will also increase proportionally by 8% due to the added sales tax.
Similarly, if the item's price (p) decreases, the total cost (f) will also decrease proportionally by 8%.
This relationship holds true for all values of p and f as long as the sales tax rate remains constant at 8%.

3x-9=x-8
what is X??
Answer:
x=½
Step-by-step explanation:
3x-9=x-8(Group like terms)
3x-x=-8+9(You will subtract x which is also 1x from 3x which is going to be 2x Then you will add -8 to 9 making it 1(positive)).
2x=1(Divide both sides by 2)
x=½
Answer:
0.5
Step-by-step explanation:
3x-9=x-8
3x=x-8+9
3x=x+1
3x-x=+1
2x=+1
x=1/2
x=0.5
