Find the slope of the line without graphing using the 2 points below.



(3 , -10) & (4 , -21)



m = _______

Answer:

7xy + 2x^2t

Step by step explanation:

You just group the like terms and simplify (pay attention to the signs)

5xy + 2xy = 7xy

-1x^2t + 3x^2t = 2x^2t

So the answer is : 7xy + 2x^2t

Answer:

$24.

Step-by-step explanation:

I multiplied 4 by 7 to get 28. Then I multiplied $28 by three weeks and got $84. Since $84 is more than I owe I subtracted $84 by $60 and got $24. I would give my friend $60 and keep $24. Hope this helps! Have a great day!

Answer:

x=5.09 seconds (times at max)

Step-by-step explanation:

The time at which the height of the rocket is maximum is 5.09 seconds and the maximum height is 563.14 feet.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

A rocket is launched from a tower.

The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.

The quadratic equation is given below.

[tex]\rm y=-16x^2+163x+148[/tex]

Differentiate the equation with respect to x, then we have

[tex]\rm y' = \dfrac{dy}{dx}=\dfrac{d}{dx}(-16x^2+163x+148)\\\\y' =-32x + 163[/tex]

For y' = 0, then we have

32x = 163

   x = 5.09

Then the maximum value of the rocket will be

[tex]\rm y=-16(5.09)^2+163(5.09)+148\\\\y = - 414.53 + 829.67 + 148\\\\y = 563.14\ ft[/tex]

The 17th term number of the arithmetic sequence will be: -97

i.e.

Step-by-step explanation:

Given the arithmetic sequence

[tex]a_n=-6n+5[/tex]

Put [tex]n=17[/tex] in the arithemetic sequence to get the 17th term number

[tex]a_{17}=-6\left(17\right)+5[/tex]

[tex]a_{17}=-6\cdot \:17+5[/tex]

[tex]a_{17}=-102+5[/tex]

[tex]a_{17}=-97[/tex]

Therefore, the 17th term number of the arithmetic sequence will be: -97

Answer: B. 16 feet

Step-by-step explanation:

We know that the length is 20 feet longer that the width. If the length of the park is 36 feet, the width is 20 feet less.

36 - 20 = 16 feet

So, the width of the park is 16 feet.

Answer:

draw a line trough (2,3) and (0, 2)

Step-by-step explanation:

f(x)=(3/2)x+2

so 3/2 is your slope  and 2 is your y coordinate of y-intercept

pick any point to start for example (0, 0) and go slope=rise/run=3/2 and you will end-up at (2,3)

now you have a point (2,3) and a second the y-intercept (0,2)

draw a line trough those points

Answer:

c is circumference which is equal to 3.14 multiplied by d  

Step-by-step explanation:

Given:

Endpoints of a segment are J(−24,−4) and K(−4,6).

To find:

The equation in point-slope form for the perpendicular bisector of JK.

Solution:

Slope of JK is

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

[tex]m=\dfrac{6-(-4)}{-4-(-24)}[/tex]

[tex]m=\dfrac{6+4}{-4+24}[/tex]

[tex]m=\dfrac{10}{20}[/tex]

[tex]m=\dfrac{1}{2}[/tex]

Product of slopes of two perpendicular lines is -1. So, product of perpendicular line of JK is -2.

Perpendicular bisector of JK passes through the midpoint of JK.

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-24-4}{2},\dfrac{-4+6}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-28}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-14,1\right)[/tex]

Point slope form:

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope.

Perpendicular bisector of JK passes through (-14,1) with slope -2. So, the point slope form of JK is

[tex]y-1=-2(x-(-14))[/tex]

[tex]y-1=-2(x+14)[/tex]

Therefore, the correct option is D.

Answer:

y = 33h + 25

Step-by-step explanation:

Given that :

Equation for the amount charged for language art session :

20h + 25 ;

Slope intercept equation :

mx + c

c = intercept, m = hourly charge

Here, the one time fee = 25

For civics:

One time fee is the same;

Hence, c = 25

Amount charged for a 3 hours civic tutoring session = $124

y = mh + c

h = number of hours ; c = $25

Amount charged per hour (m) :

$(124 - 25)/ 3

= $99 /3

= $33

m = 33

Hence,

Total charge y ;

y = 33h + 25

Answer:

"The given angle does not have a supplementary angle because supplementary angles add to the sum of 180°. The supplementary angle would then  need to be -3, and negative angles are not allowed based on the definition of supplementary angles."

Step-by-step explanation:

A supplementary angle completes an angle less than 180 degrees by filling in what's left. Ex. 170 and 10 are supplementary angles because they add up to a straight line, 180.

Since 183 is greater than 180, no angle (a negative angle isn't an angle) can complete it.

Answer:

2 feet

Step-by-step explanation:

12 feet in 6 minutes. 12/6=2

Answer:

x = 19 degrees

y = 84 degrees

Step-by-step explanation:

recall that for an isosceles triangle (which is pictured), the base angles have the same value.

In our case, we can see that the base angles are 48 deg and (3x-9) deg

if they are equal, we can equate them like this:

48 = 3x-9    (add 9 to each side)

48 + 9 = 3x

57 = 3x   (divide both sides by 3)

x = 57/3

x = 19 degrees  (answer)

also recall that the sum of the interior angles of a triangle add up to 180 deg, hence

48 deg + 48 deg + y deg = 180 deg

2(48) + y = 180

96 + y = 180

y = 180 - 96

y = 84 deg

Good luck ;)

The difference between the intercepted arc is 180°

An angle is formed from the intersection of two or more lines. Angles less than 90 degrees are called acute angles, angles greater than 90° are called obtuse angles while angles with a measure of 90° are called right angles.

Circle theorem states that if a tangent and a sectant, two tangent or two sectant meets outside a circle, the measure of the angle formed is half the difference between the intercepted arcs.

A secant and a tangent meet at a 90° angle outside the circle. Hence:

90° = (1/2) * difference between the intercepted arc

Difference between the intercepted arc = 180°

The difference between the intercepted arc is 180°
