Answer:

v=42

Step-by-step explanation:

you plug in the numbers that cordinate with each letter and you get v=18+6(4)

and then solve the equation from there starting with multiplying 6 and 4 to get 24 and then adding it to 18 which gets you 42

How many times does the graph of the function below interect or touch the x-axis? y=-2x^2+3x+5
Andrei [34K]

Answer:

Two times at (-1,0) and (2.5,0)

Step-by-step explanation:

When the graph intersects or touches x-axis, y is equal to 0

so y = -2x^2 + 3x + 5

=> 0 = -2x^2 + 3x + 5

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

so a = -2

    b = 3

    c = 5

substitute in the formula

x = [-3 +/- √(3^2 - 4x-2x5)]/2(-2)

x = [-3 +/- √(9 + 40)]/(-4)

x = [-3 +/- 7]/(-4)

x1 = (-3 + 7)/(-4) = 4/-4 = -1

x2 = (-3 - 7)/(-4) = -10/-4 = 5/2 = 2.5

so the graph has two x-intercepts (-1,0) and (2.5,0), therefore it intersects x-axis two times

#1: Solve the equation below. 5x + 7 = -3x + 31​
svlad2 [7]

Answer:

x=3

Step-by-step explanation:

You can solve by:

5x+7=-3x-31

adding 3x to each side:

8x+7=31

Subtract 7 from each side:

8x=24

Divide each side by 8:

x=3

That is your answer

Hope this helps!
