Mathematics
1 answer:
scoundrel [369]3 years ago
4 0

Answer:

B, A

Step-by-step explanation:

In the first equation, if an unknown number plus 17 equals 66, then what step would you take?

For example, if an unknown number plus 2 equaled 3, then you would know that number is 1, right? What steps did you take to get that? You subtracted 2 from both sides.

In this example, if x + 17 = 66, then subtracting 17 from both sides gets us x = 49.

The same applies for the second example. If x minus 54 equals 125, then you would add 54 to get x = 179.

Write an equation of the line parallel to 3x + 5 = 2y that has a y-intercept of -1
denpristay [2]

Answer:

3x - 2 = 2y

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 5 = 2y into this form by dividing all terms by 2

\frac{3}{2} x + \frac{5}{2} = y ← in slope- intercept form

with slope m = \frac{3}{2}

Parallel lines have equal slopes and c = - 1, thus

y = \frac{3}{2} x - 1 ← in slope- intercept form

Multiply through by 2

2y = 3x - 2 ← equation of line

Elanso [62]

Answer:

\large\boxed{(5x^3)(2x)^3=40x^6}

Step-by-step explanation:

(5x^3)(2x)^3\qquad\text{use}\ (ab)^n=a^nb^n\\\\(5x^3)(2^3x^3)=(5x^3)(8x^3)\qquad\text{use commutative law}\\\\=(5\cdot8)(x^3x^3)\qquad\text{use}\ a^na^m=a^{n+m}\\\\=40x^{3+3}=40x^6
