Answer:

373

Step-by-step explanation:

first you find the difference between the first two numbers so we do -7 minus -2=-5 then plug it in -7+5=-2 now plug in 5 for the next two numbers -2+5=3 so now we know the rule is +5 now we do 5*76=380 then we do -7+380=373

What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,
Maurinko [17]

We have been given a system of equations y=\frac{1}{2}x-4 and y=-2x-9. We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

\frac{1}{2}x-4=-2x-9

\frac{1}{2}x-4+4=-2x-9+4

\frac{1}{2}x=-2x-5

\frac{1}{2}x+2x=-2x+2x-5

\frac{1}{2}x+\frac{4}{2}x=-5

\frac{1+4}{2}x=-5

\frac{5}{2}x=-5

\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}

x=-2

Upon substituting x=-2 in equation y=-2x-9, we will get:

y=-2(-2)-9

y=4-9

y=-5

Therefore, the solution of our given system of equations would be (-2,-5) and option A is the correct choice.

The point A(-8, 6) is translated using T: (x,y) → (x + 5. y - 4). What is the distance from A to A'?
Vsevolod [243]
Translated means the points are moving across the plane without rotating or changing shape. In this case, the x-coordinate would be moving up 5 (x + 5) and the y-coordinate would be moving to the left 4 (y - 4).

A is (-8, 6). A' is the result of the translation from this point. The results of the solution above in A is the point (-3, 2) = A'.

Now you must find the distance between these two coordinates. To find the distance you must use the distance formula: √<span>(x2 - x1)^2 + (y2 - y1)^2. Since you now have two points, A and A', plug these into the distance formula.

</span>√(-3 - (-8))^2 + (2 - 6)^2
√5^2 + (-4)^2
√25 + 16
√41

The distance from A to A' is √41.

Please help!.!.! Thank you

Answer: 24 cm^2

explanation: the area of the triangle would be 6 because (3*4)/2=6. the area of the larger rectangle would be 12 because 4*3=12. the missing side is found by subtracting 8 by 4. the smaller rectangle’s area would be 6 because 4*1.5=6. add 6, 12, and 6 together and you get 24. i hope this helps!!
