how many solutions does the equation
7x + 3x - 8 = 2(5x - 4) have? explain.

Infinite solutions

Step-by-step explanation:

7x + 3x - 8 = 2(5x - 4)

distribute the 2:

7x + 3x - 8 = 10x - 8

combine like terms:

10x - 8 = 10x - 8

Here, you can completely get rid of the 8, leaving -8=-8. This is true no matter what x is, so there are infinite solutions.

Infinite Solutions

Step-by-step explanation:

So first we have to distribute;

7x + 3x - 8 = 10x - 8

Then collect like terms;

10x - 8 = 10x - 8

So this is Infinite Solutions

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
