Answer:

y=-3x+4

Step-by-step explanation:

The question is asking for the equation in slope-intercept form. This is y=mx+b where m is the slope and b is the y-intercept.

The slope can be found by counting the units in between two points on the graph. Remember that slope is rise over run or y/x. Two points on the graph are (2,-2) and (1,1). The y is increasing by 3 while x is decreasing by 1. This means the slope is -3.

The y-intercept is where the line intersects with the y-axis. In this case, that point is (0,4). Therefore, b=4.

The final answer is y=-3x+4.

Sketch the figure: Two different isosceles triangles with perimeter 4a + b

Nikitich [7]

The two triangles with the given perimeter is attached .

Perimeter is the sum of all sides.

For the first triangle , sies are 2a,2a and b.

So the perimeter is

$Perimeter = 2a+2a+b
\\
Perimeter = 4a+b$

For the second triangle, sides are a,a, and 2a+b. Therefore perimeter is

$Perimeter = a+ a + 2a+b
\\
Perimeter = 4a+b$

So for both triangles, perimeter is

$4a+b$

Answer:

90 degrees

Step-by-step explanation:

triangles add up to 180 degrees so if triangle jkl is the same as triangle rst then you add 35 to 55 and you now have t isolated with 90 degrees left in your triangle so it's 90 degrees.

If Tanisha has $nbsp 100 100 to invest at 66% per annum compounded semiannuallysemiannually, how long will it be before she h

Oxana [17]

Answer:

time is 6.76 years

Step-by-step explanation:

given data

amount = $150

payment = $100

rate r = 6% = 0.06

to find out

time period t

solution

we know it is compounding continuous

so we will apply here formula that is

amount = payment × $e^{rt}$ ..........1

put here all value we get

amount = payment × $e^{rt}$

150 = 100 × $e^{0.06t}$

take ln both side

ln 1.5 = $e^{0.06t}$

0.40546 = 0.06t

t = 0.40546 / 0.06

t = 6.76

so time is 6.76 years

How do you know the opposite of a nonzero integer?

Oksi-84 [34.3K]

The opposite of a nonzero integer is the inverse of it. So to get the opposite, change the sign.

For example:

What's the opposite of 3?

-3.

I hope that I explained well :)
