Answer:

ok so orders of operation.

Step-by-step explanation:

parenthesis,brachets: 2{3[9+4(2)-4]}

2{3[13×2-4]}

then we take whats inside the brackets and use order of operations there

13×2-4

parenthesis:none

exponents:none

multiplication: 13×2=26

division:none

addition: none

subtraction:26-4=22

then you're left with the equation:

2{3[26]}

clearly we aren't done with the brackets

so we do:

3×26=78

we're left with:

2{78}=156

your answer=156

The smaller triangle is a dilation of the larger triangle with a center of dilation at (2,−1) .
andrew-mc [135]

Answer:

Option B. 1/2

Step-by-step explanation:

The smaller triangle is a dilation of the larger triangle with the center of dilation at (2, -1).

we have to calculate the scale factor of the dilation.

One point of the large triangle is (-4, -1). After dilation it has become (-1, -1) of the smaller one.

If we consider the x coordinates of the point x = -4 has reduced down to -1 therefore scale factor = side of small triangle/side of the large triangle = (2 + 1)/(2 + 4) = 3/6 = 1/2

Therefore Option B. 1/2 is the answer.

Multiplying rational expresssions solve t^2-t-12/t+1 * t+1/t+3 Show answer with working
Andreyy89
First simplify <span>t^2-t-12, which becomes (t-4)(t+3)
now you can rewrite the expression as one term; (t-4)(t+3)(t+1)/(t+1)(t+3)
cancel out (t+3) and (t+1) which leaves the answer as (t-4)</span>

Please help me I need to get this done!!!
alukav5142 [94]

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.
