Answer:

a=7

Step-by-step explanation:

we have

7(a-10)=13-2(2a+3)

Solve for a

7a-70=13-4a-6

Group terms that contain the same variable and move the constants to the other side

7a+4a=13-6+70

Combine like terms

11a=77

Divide by 11 both sides

a=7

Which is the graph of a quadratic equation that has a negative discriminant
sergejj [24]

Answer:

The only one

Step-by-step explanation:

The one that is shown has a negative b^2-4ac value.

We know this because the function has no real roots -> that means that they must be complex, which can only occur if b^2-4ac < 0

On a coordinate plane, point A is at (3, 3) and point B is at (negative 3, 3). Point B is the image of point A when A is rotated
Vladimir [108]

Answer:

Point B must be at the same distance from the the origin as point A.

Step-by-step explanation:

Coordinates of point A = (3, 3)

When point A is rotated 90° counterclockwise around the origin, coordinates of the new point B will be (-3, 3)

Distance from origin to point A = \sqrt{(3)^{2}+(3)^2}=3\sqrt{2}

Similarly, distance of point B from the origin = \sqrt{(3)^{2}+(3)^2}=3\sqrt{2}

Therefore, distances of both the points from the origin are same.

Point B must be at the same distance from the the origin as point A.
