Complete the equation for the standard form of the line that has an x-intercept of 3 and a y-intercept of 5.
Ugo [173]

Answer:

5x+3y=15

Step-by-step explanation:

We are given two coordinates (3,0) (0,5)

Start by finding slope

y2-y1/x2-x1=  5-0/0-3= -5/3 this is your slope m.

y=mx+c

y= -5/3x+c (but remember standard line is ax+by=c) so we have to switch sides

5/3x + y=5 (remember standard form has no fraction so multiply by 3 on all sides)

5x+3y=15

How do I solve -3(3+x)+(x-6)=-4 ?
zysi [14]

\huge\boxed{x=-\frac{11}{2}}

Start by distributing the -3 to the (3+x). -3(3) + (-3)(x) + (x-6) = -4

Multiply and simplify. -9-3x+(x-6)=-4

Rearrange the terms. -3x+x-9-6=-4

Combine like terms. -2x-15=-4

Add 15 on both sides. -2x=11

Divide both sides of the equation by -2. x=\boxed{-\frac{11}{2}}

Insert grouping symbols so that the given expression has a value of 34. 14 + 10 – 6 • 8 – 3
Naily [24]

The correct answer is D. 14 + (10 – 6) • (8 – 3).

That's because in each of the other answers, we are subtracting a greater and greater number. But in this version, we are first completing the parenthesis, which gives us the following.

14 + (10 – 6) • (8 – 3)

14 + (4) • (5)

Now we complete the multiplication.

14 + 20

And we end with the addition.

34
