spin [16.1K]

Answer: 1) Let's simplify step-by-step.

x22(x+y)−y2

Distribute:

=(x22)(x)+(x22)(y)+−y2

=x23+x22y+−y2

Answer:

=x23+x22y−y2

2)Let's simplify step-by-step.

x4+x2y2+y4

There are no like terms.

Answer:

=x4+x2y2+y4

The sum of two numbers is 51. If one fourth of one number exceeds one fifth of another number by 6, which of the following is th
jeka57 [31]
<span>Let x=smaller number 
Then x+5=larger number 
Now we are told the following: 
1/5(x+x+5)=x-5 multiply each side by 5 
x+x+5=5x-25 subtract 5x and also 5 from both sides 
x+x+5-5-5x=5x-5x-25-5 collect like terms
</span><span>-3x=-30 divide both sides by -3
x=10 smaller number 
x+5=10+5=15  larger number 
CK 
1/5(10+15)=10-5 
1/5(25)=10-5
5=5 </span>

Parallel to y=−3/4x, through (4, -1)
kolbaska11 [484]

Answer:

y=-\frac{3}{4}x+2

Step-by-step explanation:

The slope-intercept form is given by y=mx+c, where m is the slope and c is the y-intercept.

Slope of given line= -\frac{3}{4}

Parallel lines have the same slope. Thus, the slope of the line would also be -\frac{3}{4}.

y=-\frac{3}{4}x +c

The value of c can be found by substituting a pair of coordinates.

When x= 4, y= -1,

-1=-\frac{3}{4} (4)+c

-1= -3 +c

<em>Add 3 to both sides:</em>

c= -1 +3

c= 2

Thus, the equation of the line is \bf{y=-\frac{3}{4}x+2.
