An 18% tip was left on a
$26 lunch bill. How much
was the tip?​

Answer: No real solutions.

Step-by-step explanation: −x2=8x+20

Step 1: Subtract8x+20  from both sides.

−x2−(8x+20)=8x+20−(8x+20)

−x2−8x−20=0

For this equation: a=-1, b=-8, c=-20

−1x2+−8x+−20=0

Step 2: Use quadratic formula with a=-1, b=-8, c=-20

Answer:

51.3

Step-by-step explanation:

Formula For Tan: tan (angle) = opposite/adjacent

Opposite = 10

Hypotenuse = 8

tan (x) = opposite/adjacent

tan (y) = 10/8

y = tan⁻¹ (10/8)

y = 51.3401917459099

y = 51.3 (rounded)

Tip: tan⁻¹ is inverse of tan.

Therefore, y = 51.3

Step-by-step explanation:

Answer:

x = 36

Step-by-step explanation:

(3x + 10) + 62 = 180

3x = 180 - 62 - 10 = 108

x = 36

Answer:

y = 10/3x + 20

Step-by-step explanation:

First, we need to find the slope of the function. We can do that by using two points and inserting them into the slope formula. It can be any two but I'll just pick (3, 30) and (6, 40).

m = y₁ - y₂ / x₁ - x₂

m = 30 - 40 / 3 - 6

m = -10/-3

m = 10/3

Now we know the slope is 10/3.

In slope-intercept form, the y-intercept is the constant at the end of the equation. The table of values tells us that the y-intercept is located at (0, 20). So the equation of the linear function is y = 10/3x + 20.

Answer:

[tex]=32 \sqrt{3x[/tex]

Step-by-step explanation:

Given that:

[tex]Simplify \ \sqrt{(64x)(12)}[/tex]

[tex]When \ simplifying \ radicals, we \ split \ them \ up by \ their \ factors[/tex]

i.e.

[tex]=\sqrt{64} \ * \sqrt{12} \ * \sqrt{x}[/tex]

[tex]=8 \ * 4\sqrt{3} \ * \sqrt{x}[/tex]

[tex]=32 \sqrt{3x[/tex]

Answer:

interest: $60

Payment: $360

Step-by-step explanation:

I = Prt

Interest for four years = 300 * 0.05 * 4 = 60

P = P₁ + I = 300 + 60 = 360

Explanation:

We need to find the total area first.

Break the figure into 2 parts. The part on the left is a rectangle, and the portion on the right side is a nonrectangular parallelogram.

The rectangle's area is 25*20 = 500 square meters.

The parallelogram's area is 18*10 = 180 square meters.

The formula to find the area of each is base*height

The total area of the entire figure is 500+180 = 680 square meters.

Since 1 square meter of linoleum costs $2.50, this means 680 square meters cost 680*2.50 = 1700 dollars.

Answer:

its the second, not sure about 3

Step-by-step explanation:

2^x can never be negative

g is 2^x+4, which also can never be negative

neither have a y-intercept, so im not sure about three

but they have the same domain (-inf, inf), but not the same range, as g is always greater than 4, while f can be less than 4

and thus they don't have the same asymptote

both functions have an x-intercept: 1 for f(x), 5 for g(x)

so only the second choice is correct

Answer:

[tex]y = 2x - 5[/tex]

Step-by-step explanation:

[tex]y = mx + b[/tex]

We need to leave y-term as the subject of equation.

[tex] - 4y = 20 - 8x[/tex]

Move 8x to subtract.

[tex]y = \frac{20 - 8x}{ - 4} [/tex]

Pull the negative out of 4.

[tex]y = - \frac{20 + 8x}{4} [/tex]

Simplify

[tex]y = - \frac{20}{4} + \frac{8x}{4} \\ y = - 5 + 2x[/tex]

Swap x-term and constant.

[tex]y = 2x - 5[/tex]

Answer:

Javier's equation is not correct because the variable "a" should be multiplied by  only and then added to

Step-by-step explanation:

Let

a------>is the tree’s age in years

we have that

-------> Javier's equation

we know that

The equation that represent the situation is equal to

Solve for a

Multiply by  both sides

Javier's equation is not correct because the variable "a" should be multiplied by  only and then added to

Answer:

the inequality would be p<6

the graph is below.

Step-by-step explanation:

Here's how to solve the equation:

p-4<2

add 4 to both sides

p<6
