How to solve 2x+5 if x equals 7
tatuchka [14]

Answer:

2(7) + 5 = 19

Step-by-step explanation:

Okay, so do it like this:

2x+5

x = 7

2(7) + 5

2(7) = 2 x 7

2 x 7 = 14

Now it's 14 + 5

14 + 5 = 19

Your answer is 2(7) + 5 = 19

What must be true for lines a and b to be parallel lines? Select two options.
Rasek [7]

The expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10

<h3>Lines and angles</h3>

A line is the shortest distance between two points and the point where two lines meet is known as an angle

From the figure shown

m<2 = 58 degrees (alternate exterior angle)

Since the sum of angles on a straight line is 180 degrees, hence;

3x-1+<2 + 4x - 10= 180

3x-1 + 58 + 4x - 10 =180

7x + 47 = 180

7x = 180- 47

7x = 133

x = 19

Hence the expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10

A parabola has a vertex at (4, 0) and passes through the point (6, 1). What is the equation of the parabola?
Alekssandra [29.7K]
We are given the vertex of  a parabola equal to (4, 0) and that the passes the point (6,1). In this case, it is assumed from the given that the parabola is facing upwards. In this case, the equation is (y-k) = 4a (x-h)^2 ; y = 4a (x-4)^2 when x is 6 and y is 1. then, 
 1 = 4a (6-4)^24a is equal to 1/4
the equation then is y = 1/4 (x-4)^2
