Which order pair Is a solution of y= -6x - 7

1 answer:

6 0

(x,y)
so basically an easy way to find is to subsitute values for x nd get values for y

if x=0 then
y=-6(0)-7
y=0-7
y=-7
one solution is (0,-7)

another
if x=1
y=-6(1)-7
y=-6-7
y=-13
another is (1,-13)

there are many
just try inputing the first number iin for x and see if the second number equals y
pleas include the ordered pairs

URGENT PLEASE HELP ME

Answer:

110in

Step-by-step explanation:

You are given the angle and the length of one leg of the triangle. Therefore, you will want to use one of the trigonometric formulae you've learnt. The available ones are:

$sin(\theta)=\frac{O}{H}\\cos(\theta)=\frac{A}{H}\\tan(\theta)=\frac{O}{A}\\$

where O represents the leg opposite the angle, A represents the leg Adjacent to the angle, and H represents the hypotenuse. The lamppost in this problem is the leg opposite the angle, so you want a formula that has O in the equation, namely sin or tan. Because you were given the leg adjacent to the angle, it makes sense here to use tan. Set up the equation as such to solve:

$tan(70)=\frac{x}{40}\\40*tan(70)=x\\x=110\\$

For some reason, it wanted you to convert 70 degrees to radians, so that may have been where you could have run into issues. If you plugged in 70 as degrees, you would get 48 which isn't an option. Converting 70 to 1.22 rad gets you the answer of 110 in.

The function, B (x), models the estimated tuition cost where x is the number

zepelin [54]

The expression that completes the function b(x) is b(x) = 33741 * (1.028)^x

<h3>How to determine the expression of b(x)?</h3>

The given parameters are:

Initial value, a = 33741

Rate, r = 2.8%

The cost of tuition each year since 2015 is represented as

B(x) = a * (1 + r)^x

This gives

B(x) = 33741 * (1 + 2.8%)^x

Evaluate

b(x) = 33741 * (1.028)^x

Hence, the expression that completes the function b(x) is b(x) = 33741 * (1.028)^x

B maybe or A
Because 15 percent of 212 is 31.8 so it’s closer to 40 maybe
