Answer:

Part A: x+y=75 is the 1st linear equation

y=25+x

Part B:

x+y=75

x+(25+x)=75

2x=50

x=25

she spends 25 mins running

part c : no because if she spends 45 mins

then x+y=70

but x+y=75

she spends 50 mins dancing

Answer:

Answer:

x = 28

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees.

50 + 2x + (3x-10) = 180

5x = 140

x = 28

This is pretty simple once you figure out the trick.

All you have to do is make the args common.

Meaning [tex]log_{6}(x + 1) + log_{6}(x) = 1[/tex] is nothing but [tex]log_{6}(x(x + 1)) = 1[/tex]

Which is nothing but: [tex]log_{6}(x^2 + x) = 1[/tex].

Now using the scorpion tail method, this equation can be reframed to being: [tex]6 = x^2 + x[/tex]. You bring 6 to the other side and it'll become: [tex]x^2 + x - 6 = 0[/tex]

Factorise it and you get: [tex](x - 2) * (x + 3)[/tex]

Henceforth, the solution would be [tex]2[/tex] and [tex]-3[/tex]. :D

Answer:

81 / 40

Step-by-step explanation:

The Maclaurin expansion of sin x is:

sin x = ∑ₙ₌₀°° (-1)ⁿ x²ⁿ⁺¹ / (2n+1)!

sin x = x − x³/3! + x⁵/5! − x⁷/7! + ...

Substituting this into the limit:

lim(x→0) [sin(3x) − 3x + ⁹/₂ x³] / x⁵

lim(x→0) [(3x − (3x)³/3! + (3x)⁵/5! − (3x)⁷/7! + ...) − 3x + ⁹/₂ x³] / x⁵

lim(x→0) [(3x − ⁹/₂ x³ + 3⁵x⁵/5! − 3⁷x⁷/7! + ...) − 3x + ⁹/₂ x³] / x⁵

lim(x→0) (3⁵x⁵/5! − 3⁷x⁷/7! + ...) / x⁵

lim(x→0) (3⁵/5! − 3⁷x²/7! + ...)

3⁵/5!

Answer:

x = 2

Step-by-step explanation:

Given that the measure of segment BC must equal the addition of the measure of segment BA plus the measure of segment AC, we can write this in equation form:

BC = BA + AC

then we replace them with the measure information they provide:

12 x + 4 = 7 x - 4 + 8 x + 2

and we solve for x in the equation:

12 x + 4 = 15 x - 2

subtract 12 x from both sides:

4 = 15 x - 12 x - 2

4 = 3 x - 2

add 2 on both sides

4 + 2 = 3 x

6 = 3 x

x = 6/3

x = 2

Answer:

It would be proportional.

Step-by-step explanation:

Every 2 numbers on the X value, The y vaulue goes up by 20. It is the same number that it is inreasing by each time.

Answer:

Each one has 3 even and 3 odd numbers.

For the first one to be even there is a 3/6 probability, which reduces to 1/2.

The probability of the second one being even is also 1/2.

The probability of both being even would be 1/2 x 1/2 = 1/4 probability

Answer:

1750

Step-by-step explanation:

well first you need to know that 100 percent from yesterday is 1400, so you now want to know what 125 percent of that is. 100 x 14 is 1400 right, so 125 x 14 is 1750.

Answer:

you do not have the second system of the equation for this so we'd solve it just like we solve standard form

x = 1.5

y = 2

Step-by-step explanation:

Answ you need to find the slope using the coordinates. Then, you need to write the equation in Point-slope form and Slope-Intercept. (If ur teacher wants Standard Form do that too

Answer:

The angles are: 50.3 and 129.7

Step-by-step explanation:

The sum of supplementary angles is 180°.

Let x be one angle then the other angle will be x+79.4

Using the supplementary angle sum

[tex]x+x+79.4 = 180\\2x+79.4 = 180\\2x = 180-79.4\\2x = 100.6\\\frac{2x}{2} = \frac{100.6}{2}\\x = 50.3[/tex]

For the measurement of 2nd angle

x+79.4 => 50.3+79.4 => 129.7

Hence,

The angles are: 50.3 and 129.7
