Answer 1

Answer:

-72

Step-by-step explanation:

Substitute -4 in the equation

h(-4) = -20 + 13(-4)

h(-4) = -20 + -52

h(-4) = -72

-72 is the final answer

Answer 2

Answer:

Step-by-step explanation:

You are giving away a lot of points. Usually 20 will attract our attention. I mean you put up 20 and we get 10. It's enough.

h(t) = - 20 + 13t

First of all you need to understand that h(t) is a y value. The t is the x value.So when you see something in h(t)s value that isn't t, that's what you put in the value for t on the right side. That's the key to the problem.

In this case t is going to be - 4

h(-4) = -20 + 13(-4)

h(-4) = -20 - 52

h(=4) = -72

Find the length of PQ if PQ = QR

Answers

Answer and Step-by-step explanation:

To find the length of PQ, we need to set the length of PQ equal to the length of QR (since in the question it tells us that PQ is equal to QR).

PQ = QR

x + 1 = 12

Solve for x.

Subtract 1 from both sides of the equation.

x + 1 - 1 = 12 - 1

x = 11

Now plug this number into the expression length for PQ.

11 + 1 = 12

The length of PQ is 12.

(you can also see that QR has a length of 12, so we can just say that PQ 12).

An angle measures 85.2° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:Complementary angles are two angles whose sum is 90 degrees.

Let x represent one of the angles.

The other angle which is 84.2 degrees less would be x - 84.2.

Using this, we can write an equation.

x + (x-84.2) = 90.

Combine like terms:   2x - 84.2 = 90

Add 84.2 to both sides of the equation.

2x = 174.2

Divide by 2:  x = 87.1  

and x - 84.2 would equal 2.9.       to check: does  87.1 + 2.9 = 90?  yes.

The ratio of cats to dogs at a pet store is 4:5 which means

Answers

Step-by-step explanation:

The ratio of cats to dogs at a pet store is 4:5. It means that if there are 4 cats in the store then there are 5 dogs, if there are 8 cats(4×2) there then there will be 10 dogs(5×2).

The number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The complete question is:

The ratio of cats to dogs is 4;5 if there are 20 dogs. How many cats are there?

It is given that:

The ratio of cats to dogs at a pet store is 4:5

Let 4x be the cats and 5x be the dogs

5x = 20

The above equation is a linear equation in one variable.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

x = 20/5

x = 4

Number of cats = 4x

Plug x = 4 in the above expression:

= 4(4)

= 16

Thus, the number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

Find the equation of the line that passes through the point
(4, 11) and is perpendicular to y= 4/3x + 7

Answers

Answer:

y = -3/4x + 14

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original line.

4/3x -> -3/4x

Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].

11 = -3/4(4) + b

11 = -3 + b

14 = b

Put everything we know and solved for back into the expression.

y = -3/4x + 14

Best of Luck!

DF= 78, DE = 5x -9, EF = 2x + 10, find DE.

Answers

DF = 78, DE = 5x - 9, EF = 2x + 10, find DE.

Solve for x first.

5x - 9 + 2x + 10 = 78

7x + 1 = 78

7x = 78 - 1

7x = 77/7

x = 11

Then substitute the value of x to find DE.

DE = 5x - 9

5(11) - 9

55 - 9

DE = 46

Therefore, the value of DE is 46

Question:

DF= 78, DE = 5x -9, EF = 2x + 10, find DE.

Solution:

First, solve for the value of x.

DE + EF = DF(5x - 9) + (2x + 10) = 787x + 1 = 787x = 78 - 17x = 77/7x = 11

Then, plug and substitute the value of x to find the DE.

DE5x - 95(11) - 955 - 946

Perimeter of triangle = 3(5) = 15 cm

Perimeter of rectangle = 2(2x - 3 + 4)

Perimeter = 2(2x + 1)

Perimeter = 4x + 2
