I think it's C, try putting it in desmos to see the graph.

Determine the value of r so the line passing through each pair of points has the given slope

Nonamiya [84]

We can use the slope formula to solve this one:
$m=\frac{y_2-y_1}{x_2-x_1}$
$\frac{1}{2}=\frac{2-3}{r-6}$
$(r-6)=2(-1)$
$r-6=-2$
$r=4$

If the product of two consecutive integers is decreased by 20 times the greater integer, the result is 442. find the integers

Contact [7]

Let the first integer be x. Then the next consecutive integer is x+1.

Translating the word problem into symbols, x(x+1)-20(x+1) = 442.

Then x^2 + x - 20x - 20 = 442

or x^2 - 19x - 462 = 0

Solve by completing the square:

x^2 - 19x + 90.25 - 90.25 - 462 = 0

(x-9.5)^2 - 552.25 = 0

Taking the positive square root of both sides, we get x-9.5 = 23.5, or
x = 33

The two consecutive integers are 33 and 34.

Check: (33)(34)-20(34) = 442 (as expected).

Geometry math question please help

Jlenok [28]

To find one interior angle of a regular octagon first we need to find the sum of all interior angles of the octagon.

There is a formula to find the sum of all interior angles. The formula is

$(n-2)180^o$ , where n is the total number of sides of the polygon.

For octagon the total number of sides = 8.

So the sum of interior angles of the octagon

= $(8-2)180^o$

= $(6)(180^o)$

= $1080^o$

Now for regular octagon all the angles are equal.

There are total of 8 angles for the octagon. As all angles are same, we can find one interior angle by dividing the sum of interior angles by the number of angles.

So, the measurement of one interior angle

= $\frac{(1080^o)}{8}$

= $135^o$

We have got the required answer here. The measure of one interior angle of regular octagon is $135^o$ .

So, the correct option is option D.

$\dfrac{2}{3} \times \dfrac{3}{4} \times \dfrac{1}{2}$

Cancel out 2, the common factor for the numerator and denominator:

$= \dfrac{1}{3} \times \dfrac{3}{4} \times \dfrac{1}{1}$

Cancel out 3, the common factor for the numerator and denominator:

$= \dfrac{1}{1} \times \dfrac{1}{4} \times \dfrac{1}{1}$

Combine into single fraction:

$= \dfrac{1 \times 1 \times 1}{1 \times 4 \times 1 } = \dfrac{1}{4}$

$\bf \text {Answer = } \dfrac{1}{4}$

Tom jogged 3/7 mile on monday and 2/6 mile om Tuesday.how much farther did Tom jog on monday than Tuesday

Volgvan

3/7 (0.428571) Miles on Monday

2/6 = 1/3 (.333333) Miles on Tuesday

Subtract both numbers
