What is the least common multiple of 10, 20, and 14?
lyudmila [28]

Answer:

The least common multiple would be 140.

Step-by-step explanation:

The least common multiple is known to be a multiple that is the lowest value that satisfies being a multiple with the other factors given.

The least common multiple was 140 as it was the lowest value that satisfied being a multiple of 14, 10, AND, 20,

14 * 10 = 140

20 * 7 = 140

10 * 14 = 140

Can someone help me with this question please :( !
Natalija [7]

Answer:

D. y = 2x + 1

Step-by-step explanation:

To find the slope, you first have to find the change of y over x, and in this case, you can plainly see that each one is equal to 2. So, that means that the slope is 2. You then can use the slope to find y when x is equal to 0. In this case, y = 1 when x = 0, so that means that the y-intercept is 1. Hence, the final answer is D.

Find the axis of symmetry and the vertex of the graph of f(0) = 4x^2 - 8x +3.
olganol [36]

Answer:

Vertex: (1,-1)

Symmetry: x = 1

Step-by-step explanation:

y = 4x² - 8x + 3

y = 4(x² - 2x) + 3

y = 4[x² - 2(x)(1) + 1² - 1²] + 3

y = 4(x - 1)² - 1

In y = a(x - h)² + k,

(h,k) is the vertex

And a vertical line passing through the vertex is the line of symmetry, i.e x = h.

Vertex: (1,-1)

Symmetry: x = 1
