A fair price for the seller's 1800 square foot house is $183.68 thousand, option B is correct

Two or more expressions with an Equal sign is called as Equation.

The given linear equation represents a relationship between the square footage (x) and the price (y) of houses in the neighborhood.

We can use this equation to estimate the fair price for the seller's house by plugging in the square footage (x) of the house and solving for y:

y = 0.074x + 50

y = 0.074(1800) + 50

y = 133.2 + 50

y = 183.68

Hence, a fair price for the seller's 1800 square foot house is $183.68 thousand, option B is correct

Answer:

Step-by-step explanation:

The number of chapters read = y

Number of days spent to read = x

Slope of the line = [tex]\frac{5}{4}[/tex] ≈ 1.25

y-intercept = 2

Slope means "number of pages read per day"

For slope = 1.25 means "1.25 pages read per day"

y-intercept means "Number of pages read initially"

y-intercept = 2 means "2 pages have been already read"

Step-by-step explanation:

Ok...

Get ready to see Alot more numbers

1. Rearrange terms.

12x-15=6-3x

12x-15=-3x+6

2. Add 15 to both sides.

12−15=−3+6

12−15+15=−3+6+15

3. Simplify

If you add the numbers you will get:

12x=-3x+21

4. Add 3x to both sides of the equation.

12x=-3x+21

12x+3x=-3x+21+3x

5. Simplify

If you combine the like terms you will get,

15x=21

6. Divide both sides of the equation by the same term.

15x=21

[tex]\frac{15x}{15}[/tex] = [tex]\frac{21}{15}[/tex]

7. Simplify

If you cancel terms that are in both of the numerator and denominator, then divide the numbers you will get:

x= [tex]\frac{7}{5}[/tex]

Answer:

28

Step-by-step explanation:

Neat Question.

Thanks for posting.

The straign line (horizontal) makes an isosceles triangle inside the circle. So the bottom angle of the triangle is also 59 degrees. The central angle of the interior triangle is

180 - 59 - 59 = 62.

x and the 62 degree angle are complementary -- both are in the 90 degree angle triangle made by the tangent. x + 62 = 90

x = 90 - 62 = 28

Answer:

x = 28°

Step-by-step explanation:

PQ is tangent to circle O, ∠OPQ = 90°

∠QPR = 90-59 = 31°

mOP = mOR (radius)          ∠PRO = ∠OPR = 59°    (isosceles triangle)

∠PRO = ∠QPR + x°       (triangle exterior angle)

x = 59° - 31° = 28°

Answer:

b) use a two-sided test instead of a one sided test.

Step-by-step explanation:

If we are using a significance level of 0.05, then the two-tailed test assigns half alpha to test for statistical significance in one direction and half alpha to test statistical significance in the other direction. This implies that .025 is present in each tail of the test statistical distribution. When using the two-tailed test, regardless of the direction of the relationship you assume, we test the possibility of the relationship in both directions.

Answer:

  ∠2 = 19°

Step-by-step explanation:

Angles that are equal to 161° are vertical and corresponding angles: 1, 4, 5.

Angles that are equal to the supplement of 161° are the remaining angles: 2, 3, 6, 7.

Angle 2 is the supplement of 161°:

  ∠2 = 180° -161°

  ∠2 = 19°

Answer:

Step-by-step explanation:

The supplement of 50° is the angle that when added to 50° forms a straight angle (180° ).

Answer:

x = 8

Step-by-step explanation:

Option B is correct, f(x) = 2ˣ is an exponential parent function.

A relation is a function if it has only One y-value for each x-value.

The exponential parent function is of the form:

f(x) = aˣ

where a is a positive constant (the base of the exponential function).

Among the given options, the exponential parent function is,

⇒  f(x) = 2ˣ,

Because it has the form of an exponential function, where the base is 2.

f(x) = x is a linear function, not an exponential function.

f(x) = |x| is an absolute value function, not an exponential function.

f(x) = x² is a quadratic function, not an exponential function.

Hence,  f(x) = 2ˣ is an exponential parent function, Option B is correct.

Step-by-step explanation:

Use consistent units. The length of the roller is 2.8 m. The diameter is 168 cm = 1.68 m

Circumference of roller = 1.68π m

Contact area of roller = 1.68π × 2.8 = 4.704π m²

Each rotation levels 4.704π m² of the playground.

Area of playground = 750 rotations × (4.704π m²)/rotation

= 3528π m²

≈ 11,084 m²

Step-by-step explanation:

The population of Frisco ISD after t years is given by the following equation:

[tex]y(t) = 46000(1.06)^{t}[/tex]

How many years will pass until the population of Frisco ISD is at 100,000 students?

This is t for which [tex]y(t) = 100000[/tex]. So

[tex]y(t) = 46000(1.06)^{t}[/tex]

[tex]46000(1.06)^{t} = 100000[/tex]

[tex](1.06)^{t} = \frac{100000}{46000}[/tex]

[tex]\log{(1.06)^{t}} = \log{\frac{100000}{46000}}[/tex]

[tex]t\log{1.06} = \log{\frac{100000}{46000}}[/tex]

[tex]t = \frac{\log{\frac{100000}{46000}}}{\log{1.06}}[/tex]

[tex]t = 13.33[/tex]

So the answer is ≈ 13.33 years
