Answer:

x = 16

Step-by-step explanation:

Use that the addition of all internal angles of a triangle must add up to 180, and the fact that the two given triangles are similar:

51 + 65 + 4 x = 180

combine and solve for "x"

116 + 4 x = 180

4 x = 180 - 116

4 x = 64

x = 64 / 4

x = 16

Answer:

x = 16

Step-by-step explanation:

A triangle is 180 degrees. Since two of the angles are congruent to each other, the third angle must be congruent as well. This means that the third measure for both triangles is 4x. Knowing all of this, we can solve for x:

65 + 51 + 4x = 180

116 + 4x = 180

4x = 64

x = 16

Answer:

a. g(x) = 39x + 6

b. The price before shipping is $117 and the price after shipping is $123

Step-by-step explanation:

To represent the cost of purchasing jeans and shipping them, add 6 to the function, since it is a flat rate.

So, the function will be g(x) = 39x + 6.

Then, use this function to find the cost of 3 pairs of jeans after shipping:

g(x) = 39x + 6

g(3) = 39(3) + 6

g(3) = 117 + 6

= $123

Then, use the original function, f(x) = 39x, to find the price before shipping:

f(x) = 39x

f(3) = 39(3)

= $117

So, the price before shipping is $117 and the price after shipping is $123

for D. the balloon ends up and 3

Answer:

Step-by-step explanation:

to go from (4, 3/4 ) to (6, 0) you need

a line with slope m= (y2-y1)/(x2-x1) = [tex]\frac{3}{4}[/tex] -0 / 4-6 = [tex]\frac{3}{4} /\frac{-2}{1} =\frac{3}{4} *\frac{-1}{2} =\frac{-3}{8}[/tex]

use the quation of a line point-slope

(y-y1)=m(x-x1)

substitute m= -3/8 and (x1,y1) with (6,0)

[tex]y=\frac{-3}{8} (x-6)[/tex]

Now does point (10,4) where is the aim is verified by this equation?

substitute x=10, y=4 in the equation to check

4= -3(10-6)/8

4= -3*4/8

4=-3/2 this is never true so you do NOT make the shot

a.) The equation for the path of the ball is:[tex]\(y = -\frac{3}{8}x + \frac{9}{4}\).[/tex]

b.) The equation is not true because 4 is not equal to -3/2. Therefore, the ball does not make it into the pocket. The bank shot is not successful.The reason the shot fails is that the path of the ball (as represented by the linear equation) does not intersect the pocket point (10, 4), so the ball does not reach the desired target.

a.) To find the equation for the path of the ball, we can use the concept of a linear equation, which represents a straight line on the coordinate plane. The general form of a linear equation is:

[tex]\(y = mx + b\)[/tex]

where:

- y is the y-coordinate of a point on the line.

- x is the x-coordinate of the same point.

- m is the slope of the line (change in y divided by change in x).

- b is the y-intercept, which is the point where the line intersects the y-axis (x = 0).

a.) Equation for the path of the ball:

We can find the slope m of the line passing through (4, 3/4) and (6, 0) as follows:

[tex]\(m = \frac{{y_2 - y_1}}{{x_2 - x_1}} \\= \frac{{0 - \frac{3}{4}}}{{6 - 4}} \\= \frac{{-\frac{3}{4}}}{{2}} \\= -\frac{3}{8}\)[/tex]

Now, let's find the y-intercept b by substituting the values of (x, y) from one of the given points (let's use (4, 3/4)) and the calculated slope m :

[tex]\(y = mx + b\)\\\(\frac{3}{4} = -\frac{3}{8} \times 4 + b\)\\\(\frac{3}{4} = -\frac{3}{2} + b\)[/tex]

Now, solve for

[tex]\(b\): \(b = \frac{3}{4} + \frac{3}{2}\\ = \frac{3}{4} + \frac{6}{4} \\= \frac{9}{4}\).[/tex]

b.) To determine if the ball makes it into the pocket at (10, 4), we need to check if the y-coordinate (4) of the pocket point lies on the path of the ball. Substitute [tex]\(x = 10\) and \(y = 4\)[/tex] into the equation for the path of the ball:

[tex]\(4 = -\frac{3}{8} \times 10 + \frac{9}{4}\)\\\(4 = -\frac{30}{8} + \frac{9}{4}\)[/tex]

Now, let's find a common denominator and simplify:

[tex]\(4 = -\frac{30}{8} + \frac{18}{8}\)\\\(4 = -\frac{12}{8}\).[/tex]

Step-by-step explanation:

I think it means to find the perimeter  and multiply it by 8.

The perimeter of a circle is called the circumference.

C = pi(d)

C = pi(2.4)

C = 7.536

My teacher has us use 3.14 for pi so if your teacher has you use something else just multiply it by 2.4.

Answer:

x+7 ≤ 20

Just take it step by step:

seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.

it then says it's equal to at most 20.

This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals
