For this one, plug in your x and y intercepts for the corresponding letters and see which one is true.  I always start with the first equation and then see which ones solve it first, that will cut your time down on a test.

Lets start with A. (4,5)

and the first equation y=x+1

5=4+1, which is true so A is a potential answer

B. (2,3)

3=2+1, B is a potential as well

C. (-2,1)

1=-2+1, which is false so C is out

D. (-4,-3)

-3=-4+1, which is true.

To cut down on time, do the same thing with the second equation and your final answer will be A. (4,5)

Answer:

Bus drop him off 64 miles far from the school.

Explanation:

 Total distance traveled by Nigel from Home to school each day = 312 miles

 Distance from bus stop to his home = 14 miles

Distance traveled by Nigel on the city bus = 234 miles.

Distance from bus drop off position to school = X miles

We have Total distance traveled by Nigel = 14+234+X = 248+X

Equating both total distances

          248+X = 312

            X = 64 miles.

 So bus drop him off 64 miles far from the school.

d - e = 2d - e      add e to both sides

d - e + e = 2d - e + e

d = 2d      subtract d from both sides

d - d = 2d - d

0 = d

Answer: D = 0

Thus meaning D has to equal 0.

Aiden spent $22.20 on 60 candles. His sister spent $54.40 on 170 candles, $32.20 more than Aiden.

Let's break this down step by step:

a. To find out how much Aiden spent on candles, we multiply the number of candles he bought (60) by the price per candle ($0.37):

Total cost for Aiden = 60 × $0.37 = $22.20

So, Aiden spent $22.20 on candles.

b. Aiden's sister bought 170 candles and paid $0.05 less per candle than Aiden did. This means she paid $0.37 - $0.05 = $0.32 per candle.

To find out how much Aiden's sister spent on candles, we multiply the number of candles she bought (170) by the price per candle ($0.32):

Total cost for Aiden's sister = 170 × $0.32 = $54.40

So, Aiden's sister spent $54.40 on candles.

c. To compare who spent more on candles, we simply compare the total costs. Aiden spent $22.20 and his sister spent $54.40.

Aiden's sister spent more. To find out how much more she spent, we subtract Aiden's total from his sister's:

$54.40 - $22.20 = $32.20

So, Aiden's sister spent $32.20 more on candles than Aiden did.

The complete question is here:

To prepare for a wedding, Aiden bought 60 candles. He paid $0.37 for each candle. His sister bought 170 candles at a sale where she paid $0.05 less for each candle than Aiden did.

a. How much did Aiden spend on candles?

b. How much did Aiden's sister spend on candles?

c. Who spent more on candles? How much more?

Final answer:

The percent drop in temperature from 80°F to 70°F is calculated as (10°F / 80°F) × 100%, which equals 12.5%.

Explanation:

To find the percent drop in temperature from 80°F to 70°F, we need to calculate the decrease in temperature and then express that decrease as a percentage of the original temperature. The decrease in temperature is 80°F - 70°F = 10°F. To find the percent drop, we use the formula for percentage change, which is (Change/Original) × 100%.

Therefore, the percent drop = (10°F / 80°F) × 100% = 12.5%. So, the temperature dropped by 12.5% from 80°F to 70°F.

Final answer:

To find the percent drop in temperature from 80°F to 70°F, calculate the difference between the temperatures and divide by the original temperature, then multiply by 100%. The result is a 12.5% decrease in temperature.

Explanation:

The question asks to find the percent drop in temperature when it drops from 80°F to 70°F. To calculate this, we use the formula for percent decrease, which is (original value - new value) / original value × 100%. Applying this formula, the original temperature is 80°F, and the new temperature is 70°F.

(80°F - 70°F) / 80°F × 100% = 10°F / 80°F × 100% = 0.125 × 100% = 12.5%.

Therefore, the temperature dropped by 12.5% when it fell from 80°F to 70°F.

Answer:

  6

Step-by-step explanation:

The greatest common factor (GCF) of 18, 24, and 30 is 6.

Victor can make at most 6 bags with equal numbers of each type of cookie.

_____

18 = 6×3

24 = 6×4

30 = 6×5

One way to look for the GCF is to consider the differences between the numbers. The smallest difference between any pair is 6, which also divides all of the numbers evenly. Hence 6 is the GCF.

By finding the greatest common divisor (GCD) of the counts of each type of cookie (30, 18, 24), it is determined that Victor can make 6 identical bags for the bake sale.

To determine the greatest number of bags Victor can make, we need to find the greatest common divisor (GCD) of the counts of each type of cookie: 30 chocolate chip cookies, 18 peanut butter cookies and 24 sugar cookies. The GCD is the largest number that exactly divides all these counts.

First, list the divisors of each number:

Find the highest number that appears in each list. The highest common factor of 30, 18, and 24 is 6, so Victor can make a total of 6 equal bags with each type of cookie.

EXPLANATION

Let the rectangle be oriented as shown in the diagram.

The line segment AD passes through [tex]A(2,11)[/tex].

All we need now is the slope of AD then we can find its equation.

Since AD is perpendicular t AB, we determine the slope of AB and then use it to find the slope of AD.

[tex]Slope_{AB}=\frac{1-11}{7-2}[/tex]

[tex]Slope_{AB}=\frac{-10}{5}=-2[/tex]

The slope of AD is the negative reciprocal of the slope of AB because they are perpendicular.

[tex]Slope_{AD}=\frac{-1}{-2}=\frac{1}{2}[/tex]

The equation of AD is given by;

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-11=\fra[1}{2}(x-2)[/tex]

Multiplying through by 2 gives,

[tex]2y-22=(x-2)[/tex]

[tex]2y-x-22+2=0[/tex]

[tex]2y-x-20=0[/tex]

Insert x = 100 and x = 200 in the function

f(100) = 20,000 - 40*100

= 20,000 - 4000

= 16,000

f(2)) = 20,000 - 8,000 = 12,000

So its choice C  ,  All reals between 12,000 and 16,000 inclusive.

Answer:

Option C.

Step-by-step explanation:

The given function is

[tex]f(x)=20000-40x[/tex]

where x represents the number of minutes the painter has worked from the 100-minute mark through the 200-minute mark of the project.

We need to find the practical range of the function.

The value of x lies from 100 to 200.

At x=100,

[tex]f(100)=20000-40(100)=20000-4000=16000[/tex]

At x=200,

[tex]f(200)=20000-40(200)=20000-8000=12000[/tex]

It means the practical range of the function is all real numbers between 12,000 and 16,000 inclusive.

Hence, the correct option is C.

Answer:

[tex]x = \frac{2}{3} + \frac{\sqrt{10} }{3} , x = \frac{2}{3} - \frac{\sqrt{10} }{3}[/tex]

Step-by-step explanation:

Multiplying the coefficient of x by the constant to get:

3 x (-2) = -6

Find factors of -6 that equal the middle term -4.

Since, no such factors can be found so we can solve the equation by completing the square.

To complete the square, divide the equation by the coefficient of x^2 which is 3 to get:

[tex]x^{2} - \frac{4}{3} x - \frac{2}{3} = 0[/tex]

[tex]x^{2} - \frac{4}{3} x = \frac{2}{3}[/tex]

Now divide the coefficient of x by 2 and add the square of the result to both sides of the equation:

[tex]x^{2} - \frac{4}{3} x + (-\frac{2}{3} )^{2} = \frac{2}{3} +  (-\frac{2}{3} )^{2}[/tex]

[tex](x - \frac{2}{3} )^2 = \frac{2}{3} + \frac{4}{9}[/tex]

[tex](x - \frac{2}{3} )^2 = \frac{4}{9}[/tex]

[tex]\sqrt{(x - \frac{2}{3} )^2} = \sqrt{\frac{4}{9} }[/tex]

[tex]x - \frac{2}{3} = \sqrt{\frac{10}{9} }[/tex] , [tex]x - \frac{2}{3} = -\sqrt{\frac{10}{9} }[/tex]

[tex]x = \frac{2}{3} + \frac{\sqrt{10} }{3} , x = \frac{2}{3} - \frac{\sqrt{10} }{3}[/tex]

Therefore, correct option is C.

The simplified form of the expression (25x^2-14xy+4)-(7x^2-9y)+(2xy+7) is 18x^2 - 12xy + 20 + 9y. We achieved this by applying the distributive property, grouping like terms, and simplifying each group.

To simplify the expression (25x^2-14xy+4)-(7x^2-9y)+(2xy+7), we first apply the distributive property and place minus signs before each of the terms inside the bracket:

25x^2 -14xy + 4 - 7x^2 + 9y + 2xy + 7.

From here, group like terms together:

(25x^2 - 7x^2) + (-14xy + 2xy) + (4 + 9y + 7).

Finally, simplify each group of like terms to achieve the simplified expression:

18x^2 - 12xy + 20 + 9y.
