Answer: h(6) = 11
Answer:

h(6) = 11

Hi there !

h(t) = t + 2 + 3

= t + 5

Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?

Answers

Answer:

hotdogs 3.45

rolls 2.60

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

r=3.45-.85=2.6

Answer:

  x^2 -5x +6 = 0

Step-by-step explanation:

Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...

  (2x -1)(3x -1) = 0   ⇒   roots 1/2, 1/3

Then the factoring of the equation with reciprocal roots is ...

  (x -2)(x -3) = 0

  x^2 -5x +6 = 0

what is the slope of the line on the graph?​

Answers

Please post a picture than I will be glad to help

Answer:

Step-by-step explanation:

So you need to take two points off the graph. (x,y) and (x,y)

After that use those points to plug it into this equation

your gonna want to take the Y points from both and subtract from each other.

Do the same for the X points.

Y2-Y1

X2-X1

You'll then divide The Y by the X and that the Rise over Run.  When you graph that. That'll be your answer.

From the graph

The roots are x = - 1 and x = 4 , thus factors are

2x-3x=-2+8

-1x=6

X=6/-1

X=-6

So, you want to move any number with a variable to one side and one without a variable to the other
But first, you must distribute the 2(x–4)
2(x–4) –> 2x–8
Next, move the numbers.
2x–8=3x–2
-8=x–2

For this problem, you use factorials. Factorials are when you multiply every number below it except zero. So like the factorial of 3 or 3! is 3*2*1 is 6.

Factorials are used to figure out how many combinations there are of something. So for you, we have 4 different quadrants so we write that as 4! (! is the sign for factorials.)

The measure of an angle is 66° . What is the measure of its complementary angle ?

Answers

Answer:

24º

Step-by-step explanation:

90-66 = 24º. So since complementary angles are 2 angles that add up to 90 degrees. That means that 66 + x = 90 using the information given. Then we use algebra and get that x =24. Therefore the answer is 24º.

Answer:

The supplement of 66° is the angle that when added to 66° forms a straight angle (180° ).

Step-by-step explanation:

A supplementary angle is an angle that equals 180°. So now we know that the two angles added together will give us 180°, we can use this to check at the end.

Let's call the smaller angle x

We also know that the larger number is 66° more than the smaller. This gives us:

x+x+66°=180°.

x is equal to the smaller angle, and the second angle is (x) - the smaller number with an extra 66°, giving us the difference.

Now we can simplify this by subtracting 66° from both sides.
