Answer:

the unknown, [?], has the value -18.

Step-by-step explanation:

Perform the indicated multiplication on the left side:

-14a - 18b = -14a + [?]b

Adding 14a to both sides, we eliminate a:

-18b = [?]b

Thus, the unknown, [?], has the value -18.

The graph of linear function g is shown on the grid. What is the zero of g? (-8,3) (-3,-4.5)
Ratling [72]

Answer:

Zero of the function = (-6, 0)

Step-by-step explanation:

Let the equation of the function given in the graph is,

y = mx + b

where m = slope of the line passing through two points (x_1,y_1) and (x_2,y_2) = \frac{y_2-y_1}{x_2-x_1}

b = y-intercept of the line

From the graph attached,

Slope of the line passing through (-8, 3) and (-3, 4.5) = \frac{-4.5-3}{-3+8} = -1.5

y - intercept 'b' = -9

Therefore, equation of the line will be,

y = -1.5x - 9

Function representing this line will be,

g(x) = -1.5x - 9

Zeros of the given function will be,

g(x) = 0 Or x-intercept

-1.5x - 9 = 0

x = -6

Therefore, zero of the given function is (-6, 0).

Please need the answer as fast as possible! 1/6 + 2/3​
MrMuchimi
The least common multiple of six and three is six multiply the numerator and denominator of each fraction by whatever value will result and the denominator of each fraction being equal to the least common factor which is six.
When they have like denominators which is the same ones you can add
1/6+2/3
1/6+2/3 times 2 by 2 and 3 by 2 with the 2/3 fraction
Then u get 1/6+4/6
=1+4/6
=5/6
