Answer:

y = x - 6y = -x + 5y = x - 5

Step-by-step explanation:

Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept

1. Points are:

(2, -4) and (4, -2)

Slope is:

m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1

y-intercept is - 6 as per graph

Then the formula is

y = x - 6

2. Points are:

(0,5 ) and (4, 1)

Slope is:

m = (1 - 5)/(4 - 0) = -4/4 = -1

y-intercept is 5 as per point

Then the formula is

y = -x + 5

3. Points are:

(-3, 1), (-1, -3)

Slope is

m = (3 - 1)/(-1 -(-3)) = 2/2 = 1

y-intercept is -5 as per graph

Then the formula is

y = x - 5

Find the value of the following expression.

Answers

Answer: 25 I believe

Answer:

  25

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

  a^0 = 1 . . . for a≠0

__

  [tex](2^8\cdot5^{-5}\cdot19^0)^{-2}\cdot\left(\dfrac{5^{-2}}{2^3}\right)^4\cdot2^{28}\\\\=2^{8(-2)-3(4)+28}\cdot5^{(-5)(-2)+(-2)(4)}=2^{-16-12+28}\cdot5^{10-8}\\\\=2^0\cdot5^2=\boxed{25}[/tex]

What are the values of x and y if this equation is true?

22(x + yi) + (28 + 4i) 72 – 62i

Answers

Answer:

x = 2

y = -3

Step-by-step explanation:

The given equation is,

22(x + yi) + (28 + 4i) = 72 - 62i

By solving this equation further,

22x + 22yi + 28 + 4i = 72 - 62i

(22x + 28) + (22y + 4)i = 72 - 62i

Now both the sides of the equation is in the form of complex number,

By comparing real and imaginary parts given on both the sides,

22x + 28 = 72

22x = 72 - 28

22x = 44

x = 2

22y + 4 = -62

22y = -62 - 4

22y = -66

y = -3

Therefore, x = 2 and y = -3 are the values for which the given equation is true.

Miamor wanted to make note cards by cutting pieces of paper in half.
Before starting she got seven more pieces to use. When she was done she
had 28 half pieces of paper. With how many full pieces did she start?

Answers

Answer: 14 pieces

Step-by-step explanation:

Let the number of pieces of paper she had at first be x.

Before starting she got seven more pieces to use. This can be written as:

= x + 7

When she was done she had 28 half pieces of paper. This can then be written as:

x + 7 = (28 × 1/2)

x + 7 = 14

x = 14 - 7

x = 7

Since x = 7, she started with:

= x + 7

= 7 + 7

= 14 pieces

Sam will take four science tests this quarter. Her scores on three of the tests

are shown below.

Test 1

Test 2

91%

Test 3

88%

Test 4

?

What does Sam need to score on the fourth test to ensure that she will have an

average of 90% for all four tests?

%

Answers

Answer:

98%.

Step-by-step explanation:

The following data were obtained from the question:

Test 1 (T₁) = 83%

Test 2 (T₂) = 91%

Test 3 (T₃) = 88%

Test 4 (T₄) =?

AVERAGE = 90%

We can obtain the score of 4th test by doing the following:

AVERAGE = (T₁ + T₂ + T₃ + T₄) /4

90 = (83 + 91 + 88 + T₄) /4

90 = (262 + T₄) /4

Cross multiply

90 × 4 = 262 + T₄

360 = 262 + T₄

Collect like terms

360 – 262 = T₄

T₄ = 98%

Therefore, Sam need to score 98% in the 4th test in order to have an average score of 90%.
