Find the value of x so that f(x) = 13 f(x) = 3x+4 A. 2 B. 3 C. 6 D. 4

koban [17]

Step-by-step explanation:

→ 3x + 4 = 13

→ 3x = 13 - 4 = 9

→ x = 9/3 = 3

→ x = 3

Try to solve for x, i cant figure it out

snow_lady [41]

Answer:

Step-by-step explanation:

From the upper isosceles triangle,

The answer is: x=±√5y [Note: If and only if at the lower triangle is NOT isosceles]

Exterior angle to the isosceles triangle = 2(2x^2 – 2x) [because the exterior angle of a triangle is equal to the sum of two opposite interior angles]

Therefore, the exterior angle = 4x^2 – 4x

Also,

The exterior angle is equal to the sum of the two interior base angles of the lower triangle

Thus, 4x^2 – 4x=(3x^2+4x) + (5y – 8x)

By collecting like terms,

4x^2 – 3x^2 – 4x – 4x + 8x – 5y = 0

x^2 – 5y = 0

x^2 = 5y

By taking the square root of both sides

x=±√5y

The height of a triangular flower garden is 6 feet more than the length of the base. If the area of the garden is 8 square feet,

Neko [114]

From the text you can derive the following equations:

(1) A = bh/2 = 8
(2) and h = b+6

Fill in h in (1):

b(b+6)/2 = 8 => b^2 + 6b = 16 with the quadratic formula or simply trying some values for b you can find b=2, so h=8.

Mai uses Triangle A and says the slope of this line is `\frac{6}{4}.` Elena uses Triangle B and says no, the slope of this line

nikdorinn [45]

Answer:

I agree with both of them because they are both correct

Step-by-step explanation:

See attachment for complete question;

Slope (m) is calculated using the following formula:

$m = \frac{Rise}{Run}$

Where

$Rise = Vertical\ Distance$

$Run = Horizontal\ Distance$

From the attachment, we have the following:

Triangle A

$Rise = 6\ units$

$Run = 4\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{6}{4}$

In this case, Mai is correct:

Triangle B

$Rise = 1.5\ units$

$Run = 1\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{1.5}{1}$

$m = 1.5$

In this case, Elena is also correct:

31. The bus fare in a city is $1.25. People who use the bus

o-na [289]

Answer:

12 times

Step-by-step explanation:

Without the discount pass, the bus fare is $1.25. The monthly discount pass is $15.00. 15 ÷ 1.25 is 12. So, the bus would have to be used 12 times in a month so that the total monthly cost without the discount pass is the same as the total monthly cost with the discount pass.
