Answer:

I think it's dilated by a scale factor of 5. Because the black one is 3 squares long and the purple one is 15. So divide those and you get 5! and to check just multiply 5x3 to find the length of the purple one!

Answer:

x = 5, AB = 27, BC = 19

Step-by-step explanation:

From the diagram

AB + BC = AC , substitute values

4x + 7 + 3x + 4 = 46 , that is

7x + 11 = 46 ( subtract 11 from both sides )

7x = 35 ( divide both sides by 7 )

x = 5

Thus

AB = 4x + 7 = 4(5) + 7 = 20 + 7 = 27

BC = 3x + 4 = 3(5) + 4 = 15 + 4 = 19

Answer:

1. x = 5

2. AB= 27

3. BC = 19

Step-by-step explanation:

Solving for X:

The entire segment is 46. Parts AB and BC make up the whole thing. So, to find x, add both expressions and set them equal to 46.

4x+7+3x+4=46 (combine like terms)

7x+11=46 (subtract 11 from both sides)

7x = 35 (divide by 7)

x = 5

Finding AB:

Plug 5 in for x and evaluate the expression.

4(5)+7

20 + 7= 20

AB is 27

Finding BC:

Plug in 5 for x and evaluate the expression.

3(5)+4

15+ 4=19

Check your work.

Add the values of AB and BC to make sure they add up to 46, which is AC.

27 + 19 = 46, so this is correct.

Answer:

Answer:

t=1

Step-by-step explanation:

16-2t = t + 9 +4t

combine like terms

16-2t = 5t + 9

add 2t to both sides

16-2t+2t = 5t+9+2t

combine like terms

16=7t+9

subtract 9 from both sides

16-9=7t+9-9

combine like terms

7=7t

divide both sides by 7

t=1

Answer:

16=t+9+4t+2t

16=9+7t

16-9=7t

7=7t

t=1

Answer:

x = 3

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, that is

DE = AB , substitute values

6x - 7 = 11 ( add 7 to both sides )

6x = 18 ( divide both sides by 6 )

x = 3

Answer:

See attachment :D

Step-by-step explanation:

y = 2/3x + 2

This is in slope-intercept form, y = mx+b. m is the slope, 2/3, and b is the y- intercept, 2. So you know the line intersects with the y-axis at (0,2). The slope is 2/3. So you can move up two points, then over three. Because it's a positive slope, you move right. This leaves you at point (0,3). Connect a line between these two points.

The line intersects with points (-3,0) and (0,2).

Hope this is helpful ^^ Good luck with your test :D

i think its B ......

The difference of the polynomials (5x3 + 4x2) – (6x2 – 2x – 9) is 5x3 – 2x2 + 2x + 9.

A polynomial is an expression consisting of variables and coefficients,

5x3 + 4x2 - (6x2 - 2x - 9)

= 5x3 + 4x2 - 6x2 + 2x + 9

= 5x3 - 2x2 + 2x +

The required simplified value of the f⁻¹(f(x)) is given as x.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Property of function states that function of function would be x, if the last function is an inverse function of its substituting function or vice versa. So,

f⁻¹(f(x)) = f(f⁻¹(x)) = x

Thus, the required simplified value of the f⁻¹(f(x)) is given as x.

Answer:

A

Step-by-step explanation:

They are both negative and that helps it.

Hope this helps!!!

The  values of g and h to make the expression g×h negative are g=−1; h=1 and g=1; h=−1.

An expression is combination of variables, numbers and operators.

The given expression is g×h where g and h are real numbers

The expression g×h is negative when either g or h is negative.

Since multiplying two negative numbers results in a positive number

The only way for the expression to be negative is if one of the numbers is negative and the other is positive.

So when g=−1 and h=1

The expression  g×h = -1×1 = -1.

when g=1 and h=-1

The expression  g×h = 1×-1 = -1.

Hence,  g=−1; h=1 and g=1; h=−1 are the  values of g and h to make the expression g×h negative

Answer:

A) Null hypothesis; H0: μ = 3500

Alternative hypothesis;Ha μ ≠ 3500

B) t = -1

C) the rejection region will be;

p-value < 0.05

D) Conclusion is that there is no sufficient evidence to support the claim that Ankara U. students average is not 3500 calories per day.

Step-by-step explanation:

We are given;

Population mean; μ = 3500

Population standard deviation; σ = 500

Sample mean; x¯ = 3400

Sample size; n = 25

We want to find enough evidence to conclude that Ankara U. students average is not 3500 calories per day.

Thus, the hypothesis is defined as;

A) Null hypothesis; H0: μ = 3500

Alternative hypothesis;Ha μ ≠ 3500

B) sample size is less than 30, thus we will use a t-test.

Formula for the test statistic is;

t = (x¯ - μ)/(σ/√n)

t = (3400 - 3500)/(500/√25)

t = -100/(500/5)

t = -1

C) since the sample is small, let's assume a significance level of 0.05.

Thus,the rejection region will be;

p-value < 0.05

D) from online p-value from t-score calculator attached using;

t = - 1; DF = 25 - 1 = 24; significance level = 0.05 and two tailed hypothesis, we have;

p-value ≈ 0.3273

This is greater than the significance value of 0.05.

Thus, we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that Ankara U. students average is not 3500 calories per day.
