Solving by substitution- Day 1
solve the following system of equations y=9x-9 y=9

Answers

Answer 1

Answer:

(x, y) = (2, 9)

Step-by-step explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

Answer 2

Answer:

(x, y) = (2, 9)

Step-by-step explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

UZ = 44

Step-by-step explanation:

3x+8 = 6x-28

36 = 3x

12 = x

UZ = 3(12)+8

UZ = 44

Jeff's weekly salary equals a commission of his

$430.88.

yo

Q: Find Jeff's total earnings if his sales are$948.

Answers

Answer:

His total earnings for sales of $948 is $425.84

Step-by-step explanation:

Let the percentage of his commission be a percentage with its value represented as x and b be his base salary , y as his total earnings

So we have;

y = x% of sales + base salary

for 849 sales and 417.92 , we have

417.92 = 8.49x + b •••••••(i)

for 1011 sales and 430.88 servings

430.88 = 10.11x + b ••••••(ii)

Subtract i from ii

12.96 = 1.62x

x = 12.96/1.62

x = 8

To get b, we substitute

430.88 = 10.11(8) + b

b = 430.88 - 10.11(8) = 350

Commission is 8% , base earnings is $350

So for total sales of 948;

y = 8% of 948 + 350

y = $425.84

Arrange the sentences of the paragraph proof in the most logical order.
Given: GH has a length of 16 cm.
Prove: If point 7 is the midpoint of GĦ, then GT = 8 cm.
1. If point 7 is the midpoint of GH, then GT= TH by the definition of midpoint.
2. Assume that I is the midpoint of GH and that GT+8 cm. Let GT= 5 cm.
3. GH= GT+TH by the segment addition postulate. Therefore, GH= 5 cm + 5 cm = 10 cm. GH= 10 cm and GH = 16 cm,
which is a contradiction.
4. If GT= 8 cm, then a contradiction occurs. Therefore, the original statement is true by proof by contradiction.

ANSWER: 312cm^2

ik the explanation is confusing but the answer is right

Answer:

We need to calculate the height of the 6mi by 8mi  by 10mi triangle.  In order to do this we first must calculate its area.

To calculate the area we need to use Heron's formula.

We then learn that the area is 24.

Since triangle area = .5 * base * height

then height = 2 * area / base

height = 2 * 24 / 10

height = 4.8

Triang Prism Surface area = 2 * Triangle Area + height * (a + b + c)

Triang Prism Surface area = 2 * 24 + 4.8 * (6 + 8 + 10)

Triang Prism Surface area = 48 + 4.8 * 24

Triang Prism Surface area = 163.2

2. If you buy a new mint-condition action figure, worth $106 and
your baby brother bent the packaging which reduced the value
by 22%, what is the new value of your figure?

Answers

Answer:

$82.68

Step-by-step explanation:

Original price of mint - $106

Percent discount = 22%

Discount price = 22/100 * 106

Discount price = 0.22 * 106

Discount price  = $23.32

New value = Original price - discount price

New value = 106 - 23.32

New value  = 82.68

Hence the new value of the figure will be $82.68
