Answer:

5x4=20

Step-by-step explanation:

The expression says that 20 is 4 times as many as 5, what is the same as 4 times as many as 5 is equal 20.

The meaning of the expression, if we put into equation terms, is:

4 times 5 is equal to 20

So, we can write the following equation for this expression:

4 x 5 = 20

or

5 x 4 = 20

So, the answer is the first option:

5x4=20

Answer:

The answer is 20 = 4*5.

Step-by-step explanation:

An equation is an mathematical expression where two things are equal. In this case we have a number and an product. The problem states that 20 is 4 times as many as 5. The "is" word gives us a hint that there is the equal sign, and the "times" gives us a hint that it is a product. So we can express this with:

20 = 4*5

Wich would be the first possible answer.

PLS HELP.... If 4x^2 + bx + 9 = 0, where b is the constant, has exactly one solution, what is a possible value of b ?
IgorLugansk [536]
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12

hope this helps !

Write parametric equations of the line through the points (7,1,-5) and (3,4,-2). please use the first point as your base-point w
Roman55 [17]

Given:

A line through the points (7,1,-5) and (3,4,-2).

To find:

The parametric equations of the line.

Solution:

Direction vector for the points (7,1,-5) and (3,4,-2) is

\vec {v}=\left

\vec {v}=\left

\vec {v}=\left

Now, the perimetric equations for initial point (x_0,y_0,z_0) with direction vector \vec{v}=\left, are

x=x_0+at

y=y_0+bt

z=z_0+ct

The initial point is (7,1,-5) and direction vector is \vec {v}=\left. So the perimetric equations are

x=(7)+(-4)t

x=7-4t

Similarly,

y=1+3t

z=-5+3t

Therefore, the required perimetric equations are x=7-4t, y=1+3t and z=-5+3t.
