I’m confused and don’t know why this should be easy but please help

Answer:

Step-by-step explanation:

We have to convert m to km and we have to add to find the total distance walked.

1000m = 1 km

350 m = 350 ÷ 1000 = 0.35 km

Total distance = 3.15 + 0.35

                        = 3.50 km

Answer:

m < 1 = 35

Step-by-step explanation:

this is because the lines are parallel therefore m<5=m<1

Step-by-step explanation:

f(x)=8(x-2)

if i did this right then you would substitute 30 in for x------------8 (30-2) - 20

next you would multiply 8 times 30 and 8 times -2 and you would get 240-16-20

then you would subtract and get....................... 204

Answer:

Step-by-step explanation:

f(1)=17

f(n)=f(n-1)+8.5

n           f(n)=f(n-1)+8.5                                                                          f(n)

1             f(1)=17                                                                                       17

2           f(2)=f(1)+8.5 =17+8.5=25.5                                                    25.5

3            f(3)=f(3-1)+8.25=f(2)+8.25=25.50+8.5=34                            34

Answer:

1 is y=-1/3x. 3 is y=-3/2x. 5 is y=5/3x

Step-by-step explanation:

Simply count the vertical lengths. Meaning count up or down how ever many. That is your top number. Then count your horizontal lengths, meaning left or right, this your bottom number of the slope. So if point A is at (-1,-1) in example 1, then count down 1, and right 3 spaces. Because you go down, the slope is negative, and you went down 1, so the top number is 1, you went right 3 units, so the bottom number is 3.

Answer:

19/21 is better.

Step-by-step explanation:

To find which is better, you need to divide the numerator by the denominator.

27 divided by 32 is equal to 0.84375

19 divided by 21 is equal to 0.9

0.9 is greater than 0.84375, so 19/21 is better.

Answer:

Step-by-step explanation:

2m=8

m=4

m²+1=16+1=17

m²-1=16-1=15

Therefore the Pythagorean triplets are 8,15 and 17. Here 8 is the smallest member.

Answer:  8, 15, 17

This is something you get through trial and error, or you could have memorized this particular triple.

Note how 8^2+15^2 = 17^2

Answer:

Step-by-step explanation:

To get  how far up the tree that Mr. Jones tied the rope, we will use the Pythagoras theorem since a right angle is created with the rope and the base of the tree.

The length of the rope will be the hypotenuse

The distance up the tree and away from the base will be the opposite and adjacent.

Given

length of the rope = 8feet

Distance away from the base of the tree = 6ft

According to Pythagoras;

hyp² = opp²+adj²

8² = opp²+6²

opp² = 8²-6²

opp² = 64-36

opp² = 28

opp = 5.3 feet

Hence the Mr Jones tied the rope 5.3feet above the tree. Option C is correct

[tex](y+7)(y-3)[/tex]

Step-by-step explanation:

To factorize [tex]y^2+4y-21[/tex]

[tex]\textsf{for} \ ax^2+bx+c \ \textsf{find} \ v, w \ \textsf{such that} \ v \cdot w=a \cdot c \ \textsf{and} \ v+w=b\\ \textsf{ and group into} \ (ax^2+vx)+(wx+c)[/tex]

[tex]a \cdot c=1 \cdot -21=-21[/tex]

[tex]b=4[/tex]

Therefore, the 2 numbers that multiply together to give -21 and add together to give 4 are:  7 and -3

[tex]\implies y^2+7y-3y-21[/tex]

[tex]\implies (y^2+7y)+(-3y-21)[/tex]

Factor the parentheses:

[tex]\implies y(y+7)-3(y+7)[/tex]

Factor out the common term [tex](y+7)[/tex]:

[tex](x + 4)(x + 5)[/tex]

[tex]x \times x + 5x + 4x + 4 \times 5[/tex]

[tex]x {}^{2} + 5x + 4x + 20[/tex]

[tex]x {}^{2} + 9x + 20[/tex]

The standard form of the expression (x+4)(x+5) is  x²+9x+20.

An expression is combination of variables, numbers and operators.

The given expression is (x+4)(x+5)

x is the variable in the given expression.

We have to multiply and simplify the expression.

Let split the expression as below.

x(x+5)+4(x+5)

Apply the distributive property

x²+5x+4x+20

Combine the like terms

x²+9x+20

x²+9x+20 is the standard form of the expression (x+4)(x+5)

Hence, the standard form of the expression (x+4)(x+5) is  x²+9x+20.

Answer:

b>9

Step-by-step explanation:

Answer:

b > 9

Step-by-step explanation:

Inequalities represent the value of a variable in relation to other numbers.

Solving the Inequality

The properties of equality state that if you add or subtract a number from both sides, the statement remains true. This means that we can isolate the variable by using the properties of equality.

Understanding the Answer

The answer to the inequality is b > 9. This means that the variable must be greater than 9. So, values such as 10 or 100 could all be solutions. However, remember that 9 itself is not a solution. The inequality only accounts for values greater than 9, not equal to.
