Answer 1

Answer:

we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Step-by-step explanation:

Given the expression

[tex]4 < -2x + 3 < 9[/tex]

SECOND STEP

subtract 3 from the right-hand side as well as on the left-hand side

[tex]4-3 <-2x+3-3<9-3[/tex]

SOLVING THE REMAINING COMPLETE COMPRESSION

[tex]1 < -2x < 6[/tex]

Divide all parts by -2

Please note that multiply or divide an inequality by a negative number flips the inequality sign.

so the expression becomes

[tex]\frac{1}{-2}\:<\:\frac{-2x}{-2}\:<\:\frac{6}{-2}[/tex]

[tex]\frac{1}{-2}\:>x\:<\:-3[/tex]

Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length of the LONGEST side of the kite. Only write the value of the longest side.

Answers

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

[tex]Perimeter = 50[/tex]

[tex]a=b + 1[/tex]

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

[tex]Perimeter = 2(a + b)[/tex]

Make b the subject in [tex]a=b + 1[/tex]

[tex]b = a -1[/tex]

Substitute a - 1 for b and 50 for Perimeter in [tex]Perimeter = 2(a + b)[/tex]

[tex]50 = 2(a + a - 1)[/tex]

Divide through by 2

[tex]25 = a + a - 1[/tex]

[tex]25 = 2a- 1[/tex]

Add 1 to both sides

[tex]25 + 1 = 2a - 1 +1[/tex]

[tex]25 + 1 = 2a[/tex]

[tex]26 = 2a[/tex]

Solve for a

[tex]a = 26/2[/tex]

[tex]a = 13[/tex]

Hence, the length of the longest side is 13mm

X + 2x + 12y + x Apply the properties of operations by combining like terms to produce an equivalent expression. Prove your answer by showing your work.

Answers

Answer:

4(x+3y)

Step-by-step explanation:

Given the expression X + 2x + 12y + x

First thing to do is combine the like terms;

X + 2x + 12y + x

= x+x+2x+12y

Add the like terms(Addition property)

= 4x + 12y

Then factor out the like terms

= 4(x+3y)

Hence the equivalent expression is 4(x+3y)

A dog kennel boards dogs for $8 a day. The kennel will also groom a dog for $12. The DeVilles have $52 budgeted for caring for the dog while they are on vacation. How many days, d, can they put the dog in the kennel if they are going to have the dog groomed? Write an equation to model this situation and solve

Answers

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that a dog kennel boards dogs for $8 a day, the kennel will also groom a dog for $12 and that DeVilles have $52 budgeted for caring for the dog while they are on vacation.

Let the number of days that they can put the dog in the kennel if they are going to have the dog groomed be represented by d.

Therefore,

8d + 12d ≥ 52

20d ≥ 52

d ≥ 52/20

d ≥ 2.6

Since DeVilles have $52 budgeted for caring for the dog, the number of days they can put the dog in the kernel will be 2 days.

Answer:

r=f-(gm)

Step-by-step explanation:

Benz wagon has f gallons of gas

We are now told that Benz Wagon uses (g) gallons of gas for every mile traveled

Thus, amount of gas used after "m" miles is; gm

We are given r as the amount of gas remaining.

Thus;

r=f-(gm)

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t^2+64t+80 gives the height, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?

I already found the maximum height, it's at 144 feet

A. 5

B. 16

C. 2

D. 9

Answers

Answer:

5 seccs

Step-by-step explanation:

Given the modeled function of the height expressed as;

h(t)=-16t^2+64t+80

The ball hits the ground when h(t) = 0 (when the height is zero)

Substitute into the function and find t;

0 =-16t^2+64t+80

divide through by -16

0 = t²-4t-5

Factorize;

t²-4t-5 = 0

t²-5t+t-5 = 0

t(t-5)+1(t-5) = 0

(t+1)(t-5) = 0

t + 1 = 0 and t-5 = 0

t = -1 and t = 5

Time can't be negative

Hence it will take the ball 5secs before it hits the ground

Answer:

The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a.

The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.

The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

A line is a relationship between two things - but not just any relationship. When you have a linear relationship, one that can be graphed as a line, there is one big condition:

No matter how much you have of a thing (often called x), if you add one more you always get a consistent amount more of the other thing (often called y).
