Answer: slope = 1/2

Step-by-step explanation:

(y2 - y1) / (x2 - x1) = m

(4 - 3) / (6 - 4) = m

m = 1/2

slope = 1/2

Gradient is y-step/x-step

y2-y1/x2-x1

9-4/3-9

slope of line=(-5/6)

Answer:

AB = 10

EF = 2

Step-by-step explanation:

to find the scale factor you have to divide the bigger scale by the smaller one which would be

(5x)/5    and   4/x

since both scale factors should be the same you can set them even to each other

(5x)/5=4/x

solve for x

(5x)/5=4/x

x=4/x

x^2=4

x=2

Answer:[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

you can take 2 points (for example (0,-3) and (3,-1)) and use rise over run ([tex]\frac{x_{2} -x_{1} }{y_{2}-y_{1} }[/tex]) to find the slope, and just plug them into rise over run

Answer:

For this question, we'll use the numbers 0-5 for x.

x    ->      y=-1/3x+4     ->        y

0   -> y=-1/3(0)+4 = 0+4 -> y=4

1    ->  y=-1/3(1)+4 = -1/3+4 -> y=3.6667

2   -> y=-1/3(2)+4 = -0.6667+4 -> y=3.3333

3   -> y=-1/3(3)+4 = -1+4 -> y=3

4   -> y=-1/3(4)+4 = -1.3333+4 -> y=2.6667

5   -> y=-1/3(5)+4 = -1.6667+4 -> y=2.3333

Answer:top one is a

second one is c

nuber 3 is c

4 is b

Step-by-step explanation:

Answer:

1. x >= 4

2. x /= -4

3. The first one

4. The second one

Step-by-step explanation:

1. Since the bolded arrow is pointing to numbers greater than 4, we can tell that x is greater than 4. The dot on the number 4 is colored, meaning that four is included, thus x is greater than or equal to 4.

2. Since the bolded areas are on every point on the graph except -4, we can tell that x is every number but -4, thus x is not equal to -4.

3. The sign "<" indicates that x is less than 3. This eliminates the second option. Since there is no equal to sign, the dot isn't colored, thus, the first one.

4. The sign "<=" indicates that x is less than or equal to -1, eliminating the third option. Since it is equal to, the dot should be colored, thus, the second one.

Answer:

5. [tex]7^{5}[/tex]

6. [tex]27+15=42[/tex]

7. [tex]\frac{u}{10}=100[/tex] then multiply both sides by 10: [tex]u=100*10 \\u=1000[/tex]

8. [tex]28+r=128[/tex] subtract 28 from both sides: [tex]r=100[/tex]

9. So we are going to use the formula [tex]A=l*w[/tex]: [tex]A=4*2.5\\A=10[/tex]

10. So we are going to use the formula [tex]A=b*h[/tex]: [tex]A=9*4\\A=36[/tex]

Answer:

15

Step-by-step explanation:

3/7=m/35

7 x ? = 35

7 x 5 = 35

so 3 x 5 = 35

Answer: m=15

Step-by-step explanation:

you can divide 35 by 7 and that gets you 5

so if you multiply 3 by 5 you can get 15

what ever happens to one part of the fraction just do the same to the other half

Answer:

-9

Step-by-step explanation:

5(-9-4)

5(-13)

-65

4(-9+15)

4(6)

24

-65<24 so -9 is false because -65 is not smaller than 24

The solution is Option A.

The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is given by

5 ( n − 4 ) < 4 ( n + 15 )

Now , on substituting the value of n as 80 in the inequality equation , we get

5 ( n − 4 ) < 4 ( n + 15 )

when n = 80

5 ( 80 - 4 ) < 4 ( 80 + 15 )

5 ( 76 ) < 4 ( 95 )

380 = 380

So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80

Hence ,

The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Answer:The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

Answer: 10

Step-by-step explanation: The answer is 10 because xy means x times y, and since x = 10 and y = -2, 10 times -2 equals -20. Now you have to divide that by --2 which is just 2. So -20/2 equals -10. -10's absolute value is 10. Thus the answer is 10.
