4/10 = .4

3/8 = .375

.4 > .375, so Clara will reach more people

Another way to look at it:

4/10 * 40 to 4 * 4 = 16 people reached

3/8 * 40 to 3 * 5 = 15 people reached

Answer: Clara will reach more people with 1 more

Step-by-step explanation:

To solve this question, we will find the total number of people Clara can reach in 40 calls and we will also find the total number of people Toby can reach in 40 calls and then we will compare the two to be able to determine who can reach more people in the 40 phone calls.

We can use proportion to find the total number of people Clara reached in 40 calls

Let x be the total number of people Clara can reach in 40 phone calls

Since Clara can reach 4 people in 10 phone calls. Then;

4 people = 10 calls

     x        =  40 calls

cross multiply

10 × x   =   40 × 4

10x       =     160

Divide both-side of the equation by 10

10x/10  =  160/10

x =  16

The number of people Clara reached in 40 calls is 16

Now, we can also use the same method to get the number of people Toby can reach in 40 calls.

Let x represent the number of people Toby can reach in 40 calls.

Since Toby can reach 3 people in 8 calls. Then;

3 people =  8 calls

  x           = 40 calls

cross multiply

8  ×  x   =  40 ×  3

   8x    =  120

Divide both-side of the equation by 8

8x/8  =  120/8

x =  15

The number of people Toby can reach in 40 calls is 15.

Now compare;

Clara can reach 16 people in 40 calls

Toby can reach 15 people in 40 calls

Therefore, Clara can reach more people  than Toby in 40 calls

Clara can reach more people in 40 calls with 1 more person

Answer:

1. y= 1.4

Answer:

-3 = x/5

x= -15

Explanation:

To find the variable use the opposite function so if its multiplication find x by dividing and vice versa for division

you are multiplying 3 algebraic fractions together

[tex]\frac{1}{x-4}[/tex] × [tex]\frac{1}{x-4}[/tex] x [tex]\frac{1}{x-4}[/tex]

multiply the numerators together, that is 1 × 1 × 1 = 1

multiply the denominators together, that is

(x - 4 ) × (x - 4 ) × (x - 4 ) = (x - 4)³

thus the product of the multiplication is

[tex]\frac{1}{(x-4)^{3} }[/tex]

Answer:

Average decrease in car's value per year = 1800$

Explanation:

  The worth of car bought by Mr. Solan = 30000$

  Reduction of car's price = 5400$

  Number of years considered for measuring reduction of car's price = 3 years.

  Average of values = Total of the values/ Number of values.

  Average reduction per year = Total reduction/ Number of years.

                                                 = 5400/3 = 1800$

  So average decrease in car's value per year = 1800$

To evaluate a function at a specific x value simply means to substitute that particular value in place of every occurrence of the variable x.

[tex]6+2x-8=12[/tex]

Combine like terms. (6+-8)

[tex]6+-8=-2[/tex]

[tex]-2+2x=12[/tex]

Add 2 on both sides of the equation.

[tex]2+-2+2x=12+2[/tex][tex]2x=14[/tex]

Divide both sides by 2.

[tex]\frac{2x}{2}[/tex]=[tex]\frac{14}{2}[/tex]

Final answer:

The x-intercept of the graph 2(y+0.5) = 3.5x + 2y is 2/7, and the y-intercept is 0.5.

Explanation:

To find the x and y intercepts of the graph of the equation 2(y+0.5) = 3.5x + 2y, we first simplify the equation. Start by distributing the 2 on the left side:
2y + 1 = 3.5x + 2y. Next, subtract 2y from both sides to get:
1 = 3.5x. Now, to find the x-intercept, set y to zero and solve for x:

x-intercept: y = 0
1 = 3.5x
x = 1 / 3.5
x = 2/7

To find the y-intercept, set x to zero and solve for y:

y-intercept: x = 0
1 = 2y
y = 1 / 2
y = 0.5

The x-intercept is 2/7, and the y-intercept is 0.5.

1) Rewrite the equations in y = mx + b format (m = slope, b = y-intercept)

Independent: one solution ⇒  different slopes

Dependent: infinite solutions (same line) ⇒  same slope and y-intercept

Inconsistent: no solutions (parallel lines) ⇒  same slope but different y-intercepts

-21x - 3y = -24  →  -3y = 21x - 24   →  y = -7x + 8   ⇒  m = -7, b = 8

y = -7x + 7  ⇒  m = -7, b = 7

same slope but different y-intercepts = parallel lines = no solution

Answer: Inconsistent

12) Eliminate a variable for equations 1 and 2, then eliminate the same variable for equations 2 and 3.

EQ1:  x + 3y + 2z = 8   →       1(x + 3y + 2z = 8)   →    x + 3y + 2z = 8

EQ2: 3x +  y + 3z = -10  → -3(3x +  y + 3z = -10) → -9x -  3y - 9z = 30

                                                 NEW EQ 1,2:        -8x          -7z = 38

EQ2:  3x + y + 3z = -10  → 2(3x +  y + 3z = -10) →  6x + 2y + 6z = -20

EQ3: -2x - 2y -  z =  10   → 1(-2x - 2y - z = 10)  →  -2x  - 2y  -  z  =   10

                                                NEW EQ 2,3:        4x          +5z =  -10

NEW EQ 1,2:  -8x - 7z = 38   →   1(-8x - 7z = 38)   →   -8x  -  7z =  38

NEW EQ 2,3:  4x + 5z = -10  →   2(4x + 5z = -10)  →    8x + 10z = -20

                                                                                             3z  = 18

                                                                                               z = 6

NEW EQ 2,3: 4x + 5z = -10 ⇒ 4x + 5(6) = -10 ⇒ 4x + 30 = -10 ⇒ 4x = -40 ⇒ x = -10

EQ1: x + 3y + 2z = 8  ⇒  (-10) + 3y + 2(6) = 8  ⇒  3y + 2 = 8  ⇒  3y = 6  ⇒  y = 2

Answer: x = -10, y = 2, z = 6

The 2 points closest to the line is (4,12) and (20, 36)

The slope is the change in Y over the change in x:

Slope = (36-12) / (20-4)

Slope = 24 / 16

Slope = 1.5

So now you have y = 1.5x

To find the equation use the formula (y-y1) = m*(x-x1)

y-12 = 1.5(x-4)

Simplify the right side:

y-12 = 1.5x - 6

Add 12 to each side:

y = 1.5x +6

The answer is the 2nd one.

1. If the product of these integers is to be 1, then all of them must be either 1 or -1.

2. Since the product is positive (+1), it must be that there are an *even* number of negative ones (-1), if any.

3. If the sum were 0 it would mean that the number of +1's must equal the number of -1's. So that means there would have to be exactly 22/2=11 of each.

4. But if there were 11 of each, that means the number of -1's would be *odd* and there's no way the product could be +1 (as stated in 2 above).

Hence, the sum is never 0, if the product of 22 integers is equal +1.

Fun problem.

We have a positive product, so no zero factors.

We have a positive product, so an even number of negative factors.

We have a product of 1, so all the integers must be either +1 or -1.

If we have 2n factors of -1 we have 22-2n factors of 1 so a sum of

[tex]s = (-1)2n + (1)(22-2n) = 22-4n[/tex]

For that to be zero we need

[tex]0 = 22-4n[/tex]

[tex]n = 22/4 = 11/2[/tex]

That's not an integer; we've shown there's no even number of -1s that will make the sum zero, and since there must be an even number of -1s, the sum cannot equal zero.

Answer:

Your answer would be 265

Step-by-step explanation:

Your answer would be 265 because knowing that the lowest temp is a negative number, and you're trying to find the difference between a positive number from a negative number, you would have to add a number to -129 to cancel it out and make it 0. The only number that would do so would be 129. Then by using 129, add 136 to it and you will get your answer, I hope this helps :)

The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.

A car that averages 23.2 miles per gallon can travel approximately 353.8 miles using 15.25 gallons of gasoline.

If a car averages 23.2 miles per gallon of gasoline, we can calculate the distance it can travel on 15.25 gallons by multiplying the car's fuel efficiency by the amount of gasoline.

To find the distance:

Multiply the car's average miles per gallon (MPG) by the number of gallons of gasoline.

Distance = 23.2 MPG * 15.25 gallons

Distance = 353.8 miles

Therefore car that averages 23.2 miles per gallon can go approximately 353.8 miles on 15.25 gallons of gasoline.

The given quadratic equation y=x^2+4x+5 has no real solutions because the discriminant is negative. Therefore, there are no zeros for this equation, making option A (There are no zeros) the correct choice.

The question asks to identify any zeros of the quadratic equation [tex]y=x^2+4x+5.[/tex]To find the zeros, we need to set the equation equal to zero and solve for x. This is typically done using the quadratic formula, which is √x=(-b±√(b^2-4ac))/(2a), where a=1, b=4, and c=5 in our equation.

Substituting these values into the quadratic formula gives: x=(-4±√((4)^2-4*1*5))/(2*1) = (-4±√(16-20))/2 = (-4±√(-4))/2. Since the value under the square root sign (the discriminant) is negative, this equation has no real solutions. Thus, there are no zeros for the given quadratic equation, making option A the correct choice.
