Answer:
two possible combinations are
- 7 cups of lemonade and 11 cupcakes
- 10 cups of lemonade and 5 cupcakes
Step-by-step explanation:
Answer:
70 Degrees
Step-by-step explanation:
Total angle of a quadrilateral is 360 degrees. 90+130+70=290
360-290=70 Degrees
The formula for a circle is (x−h<span>)^2</span>+(y−k<span>)^2</span>=<span>r^<span>2
Where (h,k) is the center and r is the radius.
Therefore, the equation would be: (x+1)^2+(y-6)^2=9
That would be answer D</span></span>
Answer:
The equation of this line would be y = -1/2x + 1
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. To do this, we need to solve the original equation for y.
2x + 4y = 16
4y = -2x + 16
y = -1/2x + 4
The original slope (the coefficient of x) is -1/2, which means the new slope will also be -1/2 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 2 = -1/2(x + 2)
y - 2 = -1/2x - 1
y = -1/2x + 1
Answer:
A. The mean is increased by 3
Step-by-step explanation:
2 + 9 + 11 + 10 + 3 + 5 + 4 + 12 = 56/8 = 7
2 + 9 + 11 + 10 + 3 + 5 + 4 + 12 + 34 = 90/9 = 10
10 - 7 = 3
