Answer:

78

Step-by-step explanation:

Since the two angles at the bottom are congruent, you would the two equations equal to each other. So it would be:

5x-19=2x+11

Once you simplify, you will find that x= 10.

Then you plug in x for both equations, so 5(10)-19= 31 and 2(10)+11= 31

So you add up the sides: 31+31+16= 78

Answer:

a=4[tex]\sqrt{3}[/tex], b=2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

tan30=b/6, tan30=1/[tex]\sqrt{3}[/tex]  

solve for b, b=6*tan30=2[tex]\sqrt{3}[/tex]

sin30=b/a, sin30=1/2

solve for a, a=4[tex]\sqrt{3}[/tex]

[tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let these points

[tex] \begin{cases}(x_1, y_1) = ( - 4, - 1) \\ (x_2, y_2) = ( 2, 8) \end{cases}[/tex]

[tex]m = \frac{8 - ( - 1)}{2 - ( - 4)} \\ m = \frac{8 + 1}{2 + 4} \Longrightarrow \frac{9}{6} \Longrightarrow \frac{3}{2} \\ m = \frac{3}{2} [/tex]

[tex]y = mx + b \\ m = slope \\ b = y - intercept[/tex]

Substitute the value of m in the equation.

[tex]y = \frac{3}{2} x + b[/tex]

[tex](x_, y) = ( - 4, - 1)[/tex]

[tex] - 1 = \frac{3}{2} ( - 4) + b[/tex]

[tex] - 1 = \frac{3}{ \cancel{2}} ( \cancel{ - 4}) + b\\ - 1 = 3( - 2) + b \\ - 1 = - 6 + b \\ - 1 + 6 = b \\ 5 = b[/tex]

[tex]y = \frac{3}{2} x + 5[/tex]

[tex] \large \boxed{y = \frac{3}{2} x + 5}[/tex]

The given statement is false because a quadratic equation may have no solutions, one solution, or two solutions, regardless of whether it can be factored or not.

The quadratic equation is defined as a function containing the highest power of a variable is two.

A quadratic equation is a type of polynomial equation that can be written in the form ax² + bx + c = 0, where a, b, and c are constants and x is a variable.

If a quadratic equation cannot be factored, it does not mean that it does not have any solutions.

A quadratic equation may have no solutions if the discriminant, which is the quantity b² - 4ac, is less than zero.

In this case, the quadratic equation has no real solutions, as the solutions would be complex numbers.

However, if the discriminant is equal to zero, the quadratic equation has one solution, which is the value of x that makes the equation equal to zero. If the discriminant is greater than zero, the quadratic equation has two solutions, which are the values of x that make the equation equal to zero.

In summary, a quadratic equation may have no solutions, one solution, or two solutions, regardless of whether it can be factored or not.

Thus, the given statement is false.

Answer:

right triangle it is because if u make a graph and put the points u would get a right isosclses triangle

Step-by-step explanation:

The triangle ABC with verticies A(3, 3), B(6, 9) and C(6, -3) is an isosceles triangle.

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

Given, A ΔABC with verticies A(3, 3), B(6, 9) and C(6, -3).

We know the distance formula [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].

From this we find AB = √45 units, BC = 12 units and AC = √45 units.

Now, this is an isosceles triangle with two equal sides of √45 units.

Answer:

Tamu burnt 5.66 calories per minute.

Step-by-step explanation:

Tamu ran for 30 minutes.

Calories burnt by Tamu = 170 calories

Unit rate = [tex]\frac{Calories\ burnt}{Time}[/tex]

Unit rate = [tex]\frac{170}{30}[/tex]

Unit rate = 5.66 calories per minute

Therefore,

Tamu burnt 5.66 calories per minute.

Step-by-step explanation:

to find x coordinate for midpoint, add both the x coordinates then divide by two. we get x=1

to find y coordinate for midpoint, add both the y coordinates then divide by two. we get y=2

so the coordinates of midpoint is (1,2), which is F

Answer:

The answer is 1/2.

Step-by-step explanation:

1 1/3-5/6=

1 1/3 needs to be turned into a improper fraction. 1 1/3=4/3.

Now we can do 4/3-5/6 but, the denominator has to be the same. We can make them 8/6-5/6.

*(Whatever happens to the denominator, has to happen to the numerator.)

8/6-5/6=3/6. Typically, the answer could be 3/6 but you could also simplify it to 1/2.

So, the answer would be 1/2.

Answer

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Step-by-step explanation:

When you multiply exponents of the same base (variable), add the exponents.

1. The exponents are 12 - 4 + 6 = 14 or c^14

When you divide exponents of the same base, subtract them.

2. 8 - 2 = 6 or c^6

When you raise a power to a power, you multiply the exponents.

3. 4 * 5 = 20 or c^20

When a number is raised to a negative exponent it can be re written like this x^-n = 1/x^n.

4. x^-2 * y / x^4 * y^-1; using the above information, rewrite everything to have positive exponents. If the negative exponent is in the denominator, then it becomes x^n/1

y * y / x^2 * x^4 ; then just add your exponents to simplify

y^2 / x^6

As we said before, a power raised to a power is exponent x exponent.

5. (a^2 * b) ^-1 / (a^-3 * b^2)^-1 ; as before a power raised to a power, multiply the powers.

a^-2 * b-1 / a^3 * b^-2 rewrite this as before, inverting negative exponents. a^3 / a^2 * b^1 * b^2 = a^3 / a^2 * b^3

Simolifynthe new expression to reduce the a variable by subtracting the bottom a^2 from the top a^3 and are left with

a / b^3

Work number 6 like 5, no negative exponents, so there won't be any inversions. Just multiply the outside power times every exponent, then do the division by subtracting exponents of like bases.

When figuring out the problems with constants, treat them like the variables. In number 7 the 5a^2 when raised to the 2nd power would be 5^2*(a^2)^2 = 25 a^4
