Step-by-step explanation:
Beause when we say (-1,4)
It say the center of it
Answer:
D
Step-by-step explanation:
the answer you chose is correct because if you isolate x (shown below), you end up with -5. there is also no equal sign under the less than symbol, so that means it is an open circle, which it is. however, you must flip the sign when multiplying or dividing by a negative number in inequalities, so this becomes a greater than symbol, showing that x is greater than -5. this accurately portrays the given inequality on the number line.
-5x-6<19
-5x<25
x>-5
Answer: 325mm
Step-by-step explanation:
To calculate shapes like this, you need to find the area of each of the shapes and add them.
The bigger square is 15 * 15 = 225
The smaller square is 10 * 10 = 100
Then add them: 225 + 100 = 325
First, you'd need to make it an improper fraction.
Answer:
For number 15.) the area of the circle is 1,017.4
Step-by-step explanation:
To find the area of a circle using the radius the equation has to be
3.14 x Radius to the power of 2
so in this case it was 18 x 18=324
Then you multiple 324 with pie which is 3.14
324x3.14=1,017.4 rounded to the tenth
I hope this helps :))
