Which expression is equivalent to x plus 11

Answer:

Addison worked 5 hours

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y = kx

Where k is the constant of proportionality.

The relationship between the number of kilograms of dough Addison prepares (y) is proportional to the number of hours he works on it (x).

Knowing he prepared y=30 kilograms of dough after t=3 hours, we substitute in the function:

30 = 3k

Solving for k:

k = 30/3 = 10

The relationship is:

y = 10x

If he prepared y=50 kg of dough, then:

50 = 10x

Solving for x

x = 50/10 = 5

Answer:

There are 3 two topping sundaes possible.

Step-by-step explanation:

The order in which the toppings are chosen is not important. For example, chocolate and caramel topping is the same as a caramel and chocolate topping. So we use the combinations formula to solve this question.

Combinations Formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many 2 topping sundaes are possible?

2 toppings from a set of 3(chocolate, caramel and strawberry). So

[tex]C_{3,2} = \frac{3!}{2!(3-2)!} = 3[/tex]

There are 3 two topping sundaes possible.

Answer:

[tex]t = -7\ \ \ or\ \ t = 10[/tex]

Step-by-step explanation:

Given

[tex]f(t) = 2t^2 - 6t[/tex]

Required

Find t, when [tex]f(t) = 140[/tex]

Substitute 140 for f(t) in [tex]f(t) = 2t^2 - 6t[/tex]

[tex]140 = 2t^2 - 6t[/tex]

Divide through by 2

[tex]\frac{140}{2} = \frac{2t^2 - 6t}{2}[/tex]

[tex]70 = t^2 - 3t[/tex]

[tex]t^2 - 3t = 70[/tex]

Subtract 70 from both sides

[tex]t^2 - 3t - 70= 70 - 70[/tex]

[tex]t^2 - 3t - 70= 0[/tex]

Expand

[tex]t^2 -10t + 7t - 70 = 0[/tex]

Factorize:

[tex]t(t - 10) + 7(t - 10) = 0[/tex]

[tex](t + 7)(t - 10) = 0[/tex]

Split:

[tex]t + 7 = 0\ \ \ or\ \ t - 10 = 0[/tex]

[tex]t = -7\ \ \ or\ \ t = 10[/tex]

Hence, the values of t are -7 and 10

Answer:

Linear

Step-by-step explanation:

The equation y = 3x - 7 is a linear.

A linear equation represents a straight line on a graph, where the variables (in this case, x and y) have a linear relationship.

The equation has a constant coefficient (3) multiplying the variable (x), and a constant term (-7) added or subtracted.

An exponential equation involves variables in the exponent, such as

y = abˣ, where a and b are constants.

The variable x is in the exponent, indicating exponential growth or decay.

Since the equation y = 3x - 7 has a linear relationship and represents a straight line, it is classified as a linear equation.

Answer:

-1

Step-by-step explanation:

Well, at g(0), x = 0, and -2 ≤ 0 < 1, so according to the function definition, we'll need to use [tex]g(x)=-x-1[/tex] to evaluate g(0).

Plugging in 0 for x in this expression gives us [tex]g(0)=-0-1=-1[/tex].
