Answer:
5 miles per hour
Step-by-step explanation:
Using the graph, at time 1 hour, she has run 5 miles
That means the rate is 5 miles/ 1 hour
5 miles per hour
Answer:
Step-by-step explanation:
6x - 2y = -4
y= 3x + 2
We see that y = 3x + 2 so we can use that value of Y everytime we see i in the other equation.
6x - 2(3x +2) = -4
Now usually we'd we simply solve for X.
6x - 6x -4 = -4
This clearly does not work as we cannot get rid of X
Therefore, this system of equations has no solution we can find through substitution
Answer:
Equation translates to 289 + y = 206
it solves to y = -83
====================================================
Explanation:
The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.
Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206
This is the same as saying y+289 = 206
To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides
y+289 = 206
y+289-289 = 206-289
y = -83
So we are adding -83 to 289 to get 206

1. Answer – Always
The diagonals of a rhombus are always perpendicular. In fact, if the diagonals of a parallelogram are perpendicular bisectors of each other, then it must be a rhombus. In addition to this, a rhombus always has all four congruent sides.
2. Answer – Always
The diagonals of a rectangle are always congruent (i.e. they are equal in length). Furthermore, in every rectangle, the diagonals bisect each other. Because the diagonals are equal in length, each diagonal divides the rectangle into two congruent right triangles.
3. Answer – Never
The diagonals of a trapezoid are never perpendicular; the diagonals are only perpendicular in rhombuses and squares. In a trapezoid however, the diagonals are congruent. A trapezoid is a quadrilateral that has only one pair of parallel sides.
