Simplify the expression. 6h + (-7.3d) -14 +5d - 2.5h

Answer:

answer a did the test edg 2021

Step-by-step explanation:

Using translation concepts, it is found that the equation that represents the transformed function is:

[tex]y = -\sqrt{x-4} + 2[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the original graph is:

[tex]y = \sqrt{x}[/tex]

It moves up, while the new graph moves down, hence:

[tex]y = -\sqrt{x}[/tex]

It starts at (0,0), while the new graph starts at (0,2), hence:

[tex]y = -\sqrt{x} + 2[/tex]

It also goes through (4,0), that is, it was shifted 4 units to the right, hence:

[tex]y = -\sqrt{x+4} + 2[/tex]

Answer:

Replace the variable x with 5

in the expression.

f(5)=4(5)−5

Simplify => 4(5)−5.

=>15

Step-by-step explanation:

Answer:

{-5, 4}

Step-by-step explanation:

Start by factoring f(x) = x^2 + x - 20.  Since 4*5 = 20, we suspect that the factors are (x + 5) and (x - 4).

Next, set these factors equal to zero separately and solve each resulting equation for x.  We get:

{-5, 4}

What do you need help with?

Answer:   3pi/2

This is equivalent to 1.5pi

The units for the area are in square centimeters.

===============================================

Work Shown:

The larger semicircle has radius 2 cm.

So r = 2 is plugged into the area of a semicircle formula below

A = (pi*r^2)/2

A = (pi*2^2)/2

A = (4pi)/2

A = 2pi

The area of the larger semicircle is 2pi square cm.

Repeat those steps but now use r = 1. This will compute the area of the unshaded smaller semicircle

A = (pi*r^2)/2

A = (pi*1^2)/2

A = pi/2

The area of the smaller unshaded semicircle is pi/2 square cm.

------------------------

From here, we subtract the two results to get the shaded area:

(larger semicircle area) - (smaller semicircle area) = (2pi) - (pi/2) = 3pi/2

This is equivalent to 1.5pi since 3/2 = 1.5

Step-by-step explanation:

What is the rate in miles per gallon:

gallons used:           28        39        42

miles;                      628.4  947.7  1020.6

The answer is below

Solution:

A linear function is a function in the form:

y = mx + b; where y is a dependent variable, x is an independent variable, m is the rate of change of y with respect to x, and b is the initial value of y when x is zero.

From the table, we are given the gallon used to cover a distance in miles. To calculate the rate, we can select two points from the table. Using the points in the form (miles, gallons used): (628.4, 28) and (1020.6, 42) we get:

[tex]m=\frac{1020.6-628.4}{42-28}\\\\m=28\ miles\ per\ gallon[/tex]

Answer:

simply divide the numerator and denominator by 4 (the GCF). So, 1232 = 12÷432÷4 = 38. Thus, 1232 is equivalent to 38 in the reduced form. (*) The factors are numbers that multiply each other to get another number.Step-by-step explanation:

Answer:

3:8

Step-by-step explanation:

We can simplify the ratio 12 : 32 by dividing both terms by the greatest common factor (GCF).

The GCF of 12 and 32 is 4.

Divide both terms by 4.

12 ÷ 4 = 3

32 ÷ 4 = 8

Therefore:

12 : 32 = 3 : 8

Answer:

Step-by-step explanation:

[tex]4\frac{1}{2} -3 \frac{5}{6}[/tex]

1. Turn it into an improper fraction

[tex]4\frac{1}{2}[/tex] = [tex]\frac{9}{2}[/tex]

[tex]3\frac{5}{6}[/tex] = [tex]\frac{23}{6}[/tex]

[tex]\frac{9}{2} -\frac{23}{6}[/tex]

Now find a common denominator and in this case, it can be 6

[tex]\frac{9*3}{2*3} = \frac{27}{6}[/tex]

[tex]\frac{27}{6} - \frac{23}{6}[/tex] = ....

[tex]\frac{4}{6} =\frac{2}{3} (simplified)[/tex]

The solution is ,  4 1/2 - 3 5/6 = 2/3.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given that,

we the expression given and,

we have have to estimate the given expression

4 1/2 - 3 5/6

making the mix fractions in improper fraction we get,

=9/2 - 23/6

as we know, the common denominator is 6 , so, we get,

9*3 - 23/ 6

=4/6

=2/3

Hence, The solution is ,  4 1/2 - 3 5/6 = 2/3.

Answer:

B. 3

Step-by-step explanation:

The formula for finding the measure of each interior angle is below.

180(n - 2) / n where n represents the number of sides.

Since the polygon has 72 sides, we plug a 72 in for n.

So we have 180(72 - 2)/72 or 180(70)/72 which is 12600/72 or 175.

So the measure of each interior angle is 175 degrees.

2y=1+5x (moving 5x to the other side) {equation 1}

Y= (1+5x)/2 (dividing both sides by 2)

Substitute {Y=(1+5x)/2} into equation: (-8x+9y=19)

Therefore giving you:

-8x+9(1+5x)/2=19

-8x+(9+45x)/2=19

(multiply through by 2 to remove the fraction)

-16x+9+45x=38

45x-16x=38-9(grouping like terms)

29x=29

Divide both sides by 29

X=1

Substitute X=1 into equation (-5x+2y=1)

-5(1)+2y=1

(-5)+2y=1

2y=1+5

2y=6

2y/2=6/2 (dividing both sides by 2)

Y=3.

:X=1 and Y=3

Answer:

X = 1

Y = 3

Step-by-step explanation:

Given equations are;

-5x+2y=1              Eqn 1

-8x+9y=19          Eqn 2

Multiplying Eqn 1 by -8

-8(-5x+2y=1)

40x - 16y = -8     Eqn 3

Multiplying Eqn 2 by 5

5(-8x+9y=19)

-40x+45y=95     Eqn 4

Adding Eqn 3 and 4

40x - 16y - 40x + 45y = 95 - 8

29y = 87

Dividing both sides by 29

[tex]\frac{29y}{29}=\frac{87}{29}\\y = 3[/tex]

Putting y = 3 in Eqn 1

-5x + 2(3) = 1

-5x + 6 = 1

-5x = 1 - 6

-5x = -5

x = 1

Hence,

X = 1

Y = 3
