Use the graph of y=K(x) to answer the following question. What is the value of 5K(-3)-7K(-4)? (picture is attached)

The value of 5·K(-3) - 7·K(-4) is -11

Step-by-step explanation:

The graph of the function y = K(x) is given;

Given that the graph of the function is defined in the given interval of the graph from -5 < x < 5, the value of the function is given from directly reading from the graph

The value of y at x = -3 is read from the graph as y = K(-3) = 2

The value of y at x = -4 is read from the graph as y = K(-4) = 3

Therefore;

5·K(-3) - 7·K(-4) = 5 × 2 - 7 × 3 = -11

The value of 5·K(-3) - 7·K(-4) = -11

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
