Ann's rent increased from $1,200 to $1,350
By what percent did her rent increase

Answers

Answer 1
Answer:

Answer:

1% of 1200 is 12, so to find this we multiply 12 until we get 150

150/12 = 12.5

12.5%

Which equation describes a line passing through (-3,1) that is parallel to y=4x+1?A) y= -0.25x + 0.25

B) y= 4x - 11

C) y= -0.25x + 1.75

D) y= 4x + 13​

Answers

Answer:

D. y= 4x + 13

Step-by-step explanation:

the slope would have to be 4 to be parallel

so plug the points in

1=4(-3) + b

1= -12 +b

13 = b

Isiah determined that 5a2 is the GCF of the polynomiala3 – 25a2b5 – 35b4. Is he correct? Explain.

Answers

Answer:

No, Isiah is not correct. The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial. 5b4 is a factor of -25a2b5 and -35b4, but not a3. Additionally, a2 is a factor of a3 and -25a2b5, but not -35b4. 1 is the GCF of the coefficients. There are no common variables among all three terms of the polynomial.  5b4 is the GCF of –25a2b5 and –35b4, but not a3.  a2 is a factor of a3 and – 25a2b5, but not –35b4.

Considering the multiplciation of the GCF of the numeric terms and of the variables, the GCF of the polynomial is of 1, hence he is not correct.

What is the greatest common factor of a polynomial?

It is the multiplication of the GCF of the numeric constants by the GCF of the coefficients.

In this problem:

  • The coefficients of a are 3, 2 and 0, hence the GCF is a^0.
  • The coefficients of b are 0, 5 and 4, hence the GCF is b^0.
  • As for the numeric term, the terms are 1, 25 and 35, hence the GCF is 1.

Thus:

a^0 * b^0 * 1 = 1

As Isaiah did not take into account the coefficients that are zero, his calculation is not correct.

How many terms are in the arithmetic sequence 7, 0, –7, …,–175?

Answers

Answer:

27 terms

Step-by-step explanation:

a1 = 7

nth term is -175

common difference d= 0-7 = -7 or -7 - 0 = -7

nth term = first term + ( n-1) * common difference

-175 = 7 + ( n - 1 ) * (- 7)

-175 = 7 - 7n + 7

-175 = 14 - 7n

-175-14 = -7n

-189 = - 7n

n= -189 /-7

n=27

6/(x+1)-5/2=6/(3x+3)

Answers

If you would like to calculate 6/(x+1)-5/2=6/(3x+3), you can do this using the following steps:

6/(x+1)-5/2=6/(3x+3)
6/(x+1)-5/2=6/(3(x+1))      /*(x+1)
6 - 5/2 * (x+1) = 6/3
6 - 2 = 5/2 * (x+1)
4 = 5/2 * (x+1)     /*2/5
4 * 2/5 = x + 1
8/5 - 1 = x
x = 8/5 - 5/5 = 3/5

The correct result would be 3/5.

Write the equation of the line that is parallel to the line whose equation is y = –4 and that passes through the point (1, 5).A. y=-5
B. y=-4
C. y=1
D. y=5

Answers

The equation of the line, y = -4, has a slope of 0. For lines to be parallel their slopes should be equal. Given the slope and a point, the equation of the line is generally expressed as,
                                y - y1 = m(x - x1)
Substituting gives the answer of,
                                   y - 5 = 0     ;    y = 5
The answer is letter D.

How to rewrite -7x + 5y = -3 in standard form

Answers

Answer:

7x - 5y = 3

Step-by-step explanation:

The Standard Form formula is Ax + By = C, however, technically A should not be negative, and since the original is already written in an usually accepted version of Standard Form, I would assume you would just want to multiply the entire equation by -1 making the A a positive number.
