Answer:

The answer is C.) 2.25

Step-by-step explanation:

A is incorrect because when you multiply decimals, of course you can put the decimal aside for a while and multiply first which might be an easier way to multiply decimals, but you need to shift the decimal back after you’re done.

B is also incorrect because...yes it could be exponent but it’s not 2.3x5, it’s 4. 2.3x4.

D is incorrect too because 25x35 is 875, it’s not equivalent to 2.3x4 since 2.3x4 is 9.2.

The diagram shows the graph of y = 2x + c, where c is a constant find the value of K.

mote1985 [20]

Answer:

$k=\frac{13}{2}$

Step-by-step explanation:

The equation $y=2x+c$ is a linear equation. By definition, the independent term on this equation (that is, the number that is not being multiplied by $x$ ) is the y-intercept, which is a fancy way of saying "the point where the line crosses the y-axis".

By looking at the equation, we know that our y-intercept is c. By looking at the graph, we can see that the y-intercept is -3. Therefore, $c=-3$ and we get the complete version of our linear equation:

$y=2x-3$

Now, looking at the graph we can see that the point $(k,10)$ lies on the line of the equation, which means that the point is a solution to our equation. All we have to do is replace $x$ and $y$ by the values of the given point (which are $k$ and $10$ , respectively), and then solve for $k$ :
