Answer:

No, I don't think so; an equation must have an equal sign in it. Expressions, however, do not have equal signs in them. Therefore I think 15 + k is an expression, not an equation. Hope this helps :)

Answer:

The cost of the uber is a $6 flat rate plus $1.25 per mile.

Then if you take an uber for x miles, the cost will be:

c(x) = $1.25*x + $6

Now, in this case Kayla also wants to add a tip of $4, then the total cost will be:

c(x) = $1.25*x + $6 + $4  = $1.25*x + $10

And we have the restriction that Kalya can't spend more than $27.50

Then the cost must be equal or smaller than $27.50, we can write this as:

c(x) ≤ $27.50

$1.25*x + $10 ≤ $27.50

Whit the above equation we can find the maximum value of x if we isolate x in one side of the inequality.

$1.25*x + $10 ≤ $27.50

$1.25*x ≤ $27.50 - $10

$1.25*x ≤ $17.50

x ≤ ($17.50/$1.50)

x ≤ 11.67

So the maximum number of miles that she can travel on that uber is 11.67 miles, but in this cases we only work with whole numbers, so we should round it to the next whole number that meets the condition, which is 11.

x = 11

The maximum number of miles that she can travel on that uber is 11 miles.

Linear functions have a constant rate. l, domain of all real numbers, and doesnt have a vertex

Answer:

Linear functions have a constant rate. l, domain of all real numbers, and doesn't have a vertex.

Step-by-step explanation:

linear functions are a straight line. domain numbers can be but not limited to: -999 or 999, positive and negative numbers are included but not those with π or √ do not count because they are not real numbers. It doesn't have a vertex because it is a straight line, so therefore there is no vertex.

Step-by-step explanation:

Use the law of cosines

[tex]d^{2} = 9^{2} + 13^{2} - 2(9)(13) cos 41\\ = 81 + 169 - 176.602\\ = 73.3979\\d = \sqrt{73.3979} = 8.6[/tex]

Answer:

x = - 3

Step-by-step explanation:

The axis of symmetry is a vertical line passing through the vertex of the parabola with equation

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (- 3, - 6), (- 3, 4 ) with x- coordinates - 3

Then equation of axis of symmetry is x = - 3

Answer:

$84

Step-by-step explanation:

12:1 means for every dollar you bet you will win 12

so 7 x 12 = 84

you would win $84, you bet 7 so net profit would be 84-7 = $77

Net profit is $77

Step-by-step explanation:

Hello There!

The points on the scatter plot show some sort of correlation as they are grouped closely enough to create a trend line ( a line drawn where most points are at. )

If you were to draw a line through the points, the line would have a negative slope as  most of the points go down from left to right indicating that the correlation is negative

The answer is 41

Step-by-step explanation:

To solve this we must use the formula a^2+b^2=c^2. if we substitute in the values we get 9^2+40^2=c^2. The first variable is 81, then the b variable is 1600. The hypotenuse is the c value. 81+1600 is 1681, now we must find the square root of 1681. The answer is 41. Tell me if I'm wrong :)

Answer:

Mean = 4

Step-by-step explanation:

Mean = (Sum of all numbers)/(How many numbers there are)

There are 3 numbers

Mean = (5 + 4.5 + 2.5)/3

Mean = 12/3

Mean = 4

Answer:

[tex] \frac{5 + 4.5 + 2.5}{3 } = \frac{5 + 7}{3} = \frac{12}{3} = 4[/tex]

Step-by-step explanation:

[tex]5x + 3x - 4 = 10 + 8x \\ 8x - 4 = 10 + 8x \\ 8x - 8x = 10 + 4 \\ = 14[/tex]

Since x has been eliminated (8x-8x = 0), there are no solutions in this equation.

Answer:

5/8 x 4/9 = 20/72 as simplified as 5/18 in fraction form. 5/8 x 4/9 = 0.2778 in decimal form.

Step-by-step explanation:

The product of -4/9 and -5/8 is 5/18.

Given are two negative fractions -4/9 and -5/8, we need to find their product,

To find the product of two negative fractions, you can multiply their numerators together and their denominators together, while keeping the negative sign.

Let's find the product of -4/9 and -5/8:

Product = (-4/9) x (-5/8)

To calculate the product, multiply the numerators and denominators:

Product = (-4 x -5) / (9 x 8)

Simplifying the multiplication:

Product = 20 / 72

Now, you can simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which in this case is 4:

Product = (20/4) / (72/4)

= 5/18

Therefore, the product of -4/9 and -5/8 is 5/18.

Answer:

x=6

Step-by-step explanation:

Solve for x:

5 (2 x - 8) - 15 = 5

5 (2 x - 8) = 10 x - 40:

10 x - 40 - 15 = 5

Grouping like terms, 10 x - 40 - 15 = 10 x + (-40 - 15):

10 x + (-40 - 15) = 5

-40 - 15 = -55:

10 x + -55 = 5

Add 55 to both sides:

10 x + (55 - 55) = 55 + 5

55 - 55 = 0:

10 x = 5 + 55

5 + 55 = 60:

10 x = 60

Divide both sides of 10 x = 60 by 10:

(10 x)/10 = 60/10

10/10 = 1:

x = 60/10

The gcd of 60 and 10 is 10, so 60/10 = (10×6)/(10×1) = 10/10×6 = 6:
