(Picture) MULTIPLYING MONOMIALS AND BINOMIALS

Mathematics
1 answer:
Sauron [17]3 years ago
3 0

Answer:

Option C is correct, i.e. 2x² +7x -4.

Step-by-step explanation:

Given is (2x-1)(x+4)

Applying FOIL method:-

F- multiply First two, O- multiply Outer two, I- multiply Inner two, L- multiply Last two.

So, (2x-1)(x+4) = 2x*x +2x*4 -1*x -1*4

(2x-1)(x+4) = 2x² +8x -1x -4

(2x-1)(x+4) = 2x² +7x -4

Hence, option C is correct, i.e. (2x-1)(x+4) = 2x² +7x -4.

Write an equation of a line that has a y-intercept at (0, -6)
galben [10]

Answer:

y=x-6

Step-by-step explanation:

    First to write this equation you will need to know <em>slope intercept form</em> which is the equation that the people that wrote this problem are presumably looking for. Slope intercept form can be simply written as y=mx+b . The variable m would be the slope while the variable b would be the y -intercept.

    So to find out this we would have to assume that m or the slope would have to be 1 so we would have y=1x+b or y=x+b.  

    Now we have the first half of the equation we can move on to the variable b or the y-intercept (0,-6) . To find the variable b we will just have to graph the point (0,-6) which as you can see from the picture is the y-intercept and that is -6 units below 0. So the final answer will be y=x-6

What is the solution to the system shown below y=2x-1. Y=2x+3 A (0,0). B(1,-3) C(-1,3). D no solution
Setler [38]
We have that
<span>y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2

we know that
</span>If two lines are parallel<span>, then they will never intersect
</span><span>
therefore
the answer is the option
</span><span>D no solution</span><span>
