Answer:
so the equation is y=-2x-4
Step-by-step explanation:
sub the points in the equation to find the y-intercept
y=x(-2)+b
0=-2(-2)+b
0=4+b
0-4=b
-4=b
A and D. Jeffery adds $200 every year (t) to a constant of $1,200. Meanwhile you use the simple interest formula to find the correct expression for Rachel.
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
In this problem we have double parentheses. Which one should we solve first? The answer to that is always the inner most ones:
13[ 6² ÷ (5² - 4²) + 9]
5² - 4²
^^^Here you will have to first take the square of both values
25 - 16
9
13[ 6² ÷ (9) + 9]
Now for the exponents
13[ 6² ÷ (9) + 9]
6²
36
13[ 36 ÷ 9 + 9]
Now for the division:
13[ 36 ÷ 9 + 9]
36 ÷ 9
4
13[ 4 + 9]
Now for the addition
13[ 4 + 9]
4 + 9
13
13[13]
Now for multiplication
169

If the Line JK passes through points J(–3, 11) and K(1, –3), so the the equation of line JK in standard form is <span>b. 7x + 2y = 1
proof:
for </span><span>J(–3, 11), 7(-3) +2(11)=-21+22=1
</span>for <span>K(1, –3), 7(1) +2(-3)= 7-6=1</span>
