Answer:
This equation does have real solutions contrary to your question. They are 
OR 
.
Step-by-step explanation:
In order to prove this has real number solutions, we simply need to use the quadratic formula. To do this, we first need to solve for 0.
2x^2 + 18x = 10
2x^2 + 18x - 10 = 0
Now that we have this and they are all factors of 2, we can divide everything by 2 for ease.
2x^2 + 18x - 10 = 0
x^2 + 9x - 5 = 0
Now we can use the quadratic equation to solve. Remember that A = 1 due to the coefficient of x^2, B = 9 as the coefficient of x and C = -5 as the constant.
OR
The diamond is 1 the square is 6 and the triangle is 7
Answer:
-2/3.
Step-by-step explanation:
To find the slope of a line given two points, you should use the formula, Slope=y2-y1/x2-x1.In this exercise is given the coordinates of two points and it is asked to find the slope of the line which intercepts both points, which are (1,7) and (10,1). To find the slope, you should substitute the given coordinates into the previous mention formula. Slope=y2-y1/x2-x1Slope=(7-1)/(1-10)Slope=-6/9Slope=-2/3The slope of the line that passes through the points.
Answer:
4/3
Step-by-step explanation:
x + 6 - (x + 2) / 3
= x - x + 6 - 2 / 3
= 4/3
