Nataliya [291]3 years ago
3 0

Answer:

Graph the equations

Step-by-step explanation:

x - y = 1

3x + 2y = - 12

Rewrite equations into y=mx+b form:

y = -1 + x

y = -6 - 1.5x

A had $360 more than B. When A spent $144 and B spent half of his money, A had 6 times as much money as B, Find the ratio of the
Karolina [17]

Answer:

13:3

Step-by-step explanation:

A=x B=y

first; x= 360+y

later;x= 216+y

A:B

216+y: 1/2y = 6: 1

216+y/y÷2 =6/1

216+y = 3y

y = 108

first; x =360+y

360 +108

468

A:B = 468:108

Identify the polynomial x^3-y^3+z
Vaselesa [24]

Answer:

Hi there!

The answer to this question is:

Standard: y= x- (cube root) z

the leading coefficient: 1

Step-by-step explanation:

when identifying a polynomial you always need to know the standard equation, and leading coefficient.

-you first need to know what "y" so you move y to the other side by adding it on both sides

-then you need to get y by itself and cube root it on both sides resulting in x^3 becoming x and z becoming (cube root) z

which is the slope of a line that is perpendicular to the line that passes through the points (29, 24) and (3, 4)?
Nataliya [291]

Answer:

26/20

Step-by-step explanation:

y2-y1 divided by x2-x1

4-24= -20

3-29= -26

-20/-26= m

perpendicular means to switch the numbers and change the sign

a perpendicular slope to -20/-26 is 26/20.

Find the 12th and 37th term for each arithmetic sequence.
shutvik [7]

Answer:

  3.  f(12) = -10; f(37) = -60

  4.  f(12) = -102; f(37) = -352

Step-by-step explanation:

3. Put the numbers in the formula and do the arithmetic:

  f(12) = 12 -2(12-1) = 12 -22 = -10

  f(37) = 12 -2(37-1) = 12 -72 = -60

__

4. The explicit formula for an arithmetic sequence with first term a1 and common difference d is ...

  an = a1 +d(n -1)

Your sequence has a first term a1=8 and a common difference d=-10.

As above, fill in the numbers and do the arithmetic.

  f(12) = 8 -10(12 -1) = -102

  f(37) = 8 -10(37-1) = -352
