The commutative property can be used with subtraction. For example, the problem
below:
8 - 4 - 6 = 6 - 4 - 8
True
False

Answer:

x = 8

Step-by-step explanation:

40 + 6x + 2 = 90   {Complementary angles}

Combine like terms

40+ 2 + 6x = 90

     42 +6x = 90         {Subtract 42 form both sides}

             6x = 90 - 42

             6x = 48       {divide both sides by 6}

        6x/6 = 48/6

             x = 8

Answer:

-24degC

Step-by-step explanation:

-6degC dropping by 2degC leads to -8degC (2degC colder, higher value negative numbers are colder as negative numbers increase in the opposite direction of positives)

so next -8degC rising by 3degC which is 3degC hotter(less negative) will give -5degC

the finap drop by 9degC makes the final temperature -5 -19 = -24degC(similar reasoning)

if you want a more straightforward method to doing these sorts of questions, just take temperature rise : add the value it rose by and temperature fall/drop: subtract the value it dropped/falled by.

Answer:

D. [tex] \frac{3}{2} [/tex]

Step-by-step explanation:

Given:

(10, 13), (14, 19)

Required:

Determine the slope of the line that runs through the two points.

Solution:

Use the formula, [tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (10, 13) = (x_1, y_1) [/tex]

[tex] (14, 19) = (x_2, y_2) [/tex]

Plug the values into the formula:

[tex] slope (m) = \frac{19 - 13}{14 - 10} [/tex]

[tex] = \frac{6}{4} [/tex]

Simplify

[tex] slope (m) = \frac{3}{2} [/tex]

Answer:

21. 34

22. 35

22. 80

Step-by-step explanation:

21. ac=dc so..

4x+5=3x+8

simplify and you get...

x=3 then you plug it in to the formula ac+dc to get ad

4(3)+5+3(3)+8

17+17=34

22. fcd-bcd=fcb

plug in the angles

130-95=fcb

35=fcb

23. fca=ecd and acd is 180

if fca is 50, so is ecd

50+50= 100

180-100=80

so fce=80

Answer:

s=10

Step-by-step explanation:

5/4=1.25

1.25×8=10

Step-by-step explanation:

P(t) = 8 − 2√(2t + 4)

The x-intercept(s) is where t = 0.

P(0) = 8 − 2√(0 + 4)

P(0) = 8 − 4

P(0) = 4

The y-intercept(s) is where P = 0.

0 = 8 − 2√(2t + 4)

2√(2t + 4) = 8

√(2t + 4) = 4

2t + 4 = 16

2t = 12

t = 6

So the intercepts are at (0, 4) and (6, 0).

The easiest way to tell if the function is increasing or decreasing is to graph it.  Otherwise, we have to either use calculus to find the derivative, or assume the function is constantly increasing/decreasing and use limits.

lim(t→∞) P(t) = -∞

The function is decreasing.

Answer:

a. Her monthly payment is $1618.786418

b. She will pay $312763.1105 interest over the life of the loan

Step-by-step explanation:

Let us revise the rules of the monthly payments and interest

[tex]M.P=\frac{P(\frac{r}{n})}{1-(1+\frac{r}{n})^{-nt}}[/tex]

[tex]I = M.P(nt)- P[/tex]

Where:

∵ Lynn bought a $300,000 house

∵ She was paying 10% down

→ That means the initial amount is 90% of $300,000

∴ p = 90/100 × 300,000 = 270,000

∵ She was financing the rest at 6%

∴ r = 6% = 6/100 = 0.06

∵ There is a monthly payment

∴ n = 12

∵ She was financing the rest for 30 years

∴ t = 30

a.

→ Substitute these values in the first rule to finding the monthly payment

∵ [tex]M.P=\frac{270,000(\frac{0.06}{12})}{1-(1+\frac{0.06}{12})^{-12(30)}}[/tex]  

→ Let us use the calculator to find the answer

∴ M.P = $1618.786418

∴  Her monthly payment is $1618.786418

b.

→ Substitute these values in the first rule to finding the second rule

   to find the interest

∵ [tex]I = (1618.786418)(12)(30)-270,000[/tex]

→ Let us use the calculator to find the answer

∴ I = $312763.1105

∴ She will pay $312763.1105 interest over the life of the loan

The segments of the given line will form a triangle.

A triangle is a 2-dimensional shape with 3 sides and 3 angles.

For instance, a triangle ABC will have 3 sides AB, BC, and AC with corresponding angles m<C, m<A and m<B.

Given the segments below AC, BC, and AB, we can see that these segments are equivalent to 3 sides as mentioned above. Hence we can conclude that the segments of the given line will form a triangle.
