The legs of an isosceles triangle have lengths x + 1 and -x + 7 . The base has length 3x - 3. What is the length of the base?

kaheart [24]

Since this is an isosceles triangle, then the lengths of both legs are equal
Therefore,
x+1=-x+7
2x=6
x=3
Therefore, the length of the base is:
3x-3=3(3)-3=6
Then your answer is (A)

Which equation(s)

aleksandrvk [35]

Answer:

C) y = 12 x Represents the proportional relationship.

Step-by-step explanation:

Two quantities P and Q are said to be proportional if and only if:

$P \propto Q \implies P = k Y$

Here: K = Proportionality Constant

Now, here the given expression are:

$1. y = 7 x^2\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

$2. y = 2 + 3x\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

$3. y = 12 x\\\implies y = kx, k = 12$

So, y is PROPORTIONAL to x.

$2. y = 5 - x\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

The exponential model A=429e 0.024t describes the population, A, of a country in millions, t years after 2003. Use the model t

d1i1m1o1n [39]

Answer:

Year 2,590

Step-by-step explanation:

In this question, we are asked to calculate the year at which the population of a country will be a certain amount given the exponential equation through which the equation proceeds.

Let’s rewrite the exponential function;

A = 429e^0.024t

Now here, our A is 559,000,000

t is unknown

Let’s substitute this value of A in the exponential equation;

559,000,000 = 429 * e^0.024t

559,000,000/429 = e^0.024t

1,303,030.303030303 = e^0.024t

Let’s take the logarithm of both sides to base e, we have;

ln(1,303,030.303030303) = ln(e^0.024t)

14.08 = 0.024t

t = 14.08/0.024

t = 587 years

Now, we add this to year 2003 and this gives year 2590

A boating company charges $10 equipment fee and $5.50 per hour to rent a canoe. Which is the correct linear equation for this si

Solnce55 [7]

Answer:

$y =mx +b$

Where m is the slope and b the intercept.

Using the information given the variable cost 5.5 per hour represent the slope and the fixed cost 10 represent the value of b and then our model would be given by:

$y =5.5 x+ 10$

Wher y is the total cost and x the hours rented

Step-by-step explanation:

For this case we want to model the situation with a general equation given by:

$y =mx +b$

Where m is the slope and b the intercept.

Using the information given the variable cost 5.5 per hour represent the slope and the fixed cost 10 represent the value of b and then our model would be given by:

$y =5.5 x+ 10$

Wher y is the total cost and x the hours rented
