Solve each equations by substitution. y=2x
25x-y=9

Answer:

below

Step-by-step explanation:

If line C is parallel to another line, they will have the same slope. so calculate the slope first:

8-2/8-0=3/4(simplified)

and thats it

Answer:

y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

y = -3x - 1

1. Perpendicular line needs the opposite (reciprocal) of the slope.

             reciprocal of -3 is -1/3, slope 1/3.                    y = 1/3x + b

2. Now find the b (y-intercept).                                     1 = 1/3(-1) + b

                                                                                       1 = -1/3 + b

                                                                                 + 1/3  +1/3

                                                                                    1 1/3 = b

3. Answer         y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

Answer:

Step-by-step explanation:

thats just what the arrows point to

Answer:

Slope: -1

Step-by-step explanation:

Isolate y to one side to match the formula y = mx + b where m is the slope and b is the y-intercept.

y = -x + 4

Slope: -1/1

y-intercept: 4

Answer:

the slope is 4/4 which give u 1

Answer:

7 times p =   7p

Step-by-step explanation:

The algebraic expression of 7 times p is 7p.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

7 times p.

This can be written as,

= 7p

Answer:

10/8 or 1.25

Step-by-step explanation:

We can write this into an equation to help us understand what we need.

3/4=0.60x

We can make these both into fractions to make it easier.

3/4=6/10x

Divide both sides by 6/10, or multiply both sides by 10/6.

3/4×10/6=30/24=10/8=1.25

Answer: 28

the cost of 7 diaries is 28

Step-by-step explanation:

First you have to find out the cost of one diary by dividing 12 by 3, that will give us 4, and then the last step is multiplying 4 by 7.

Answer:

7 diaries cost £28

Step-by-step explanation:

12/3=4 7x4=28

Answer:

length x width

Step-by-step explanation:

for example, if a rectangle has a length of 5 and a width of 2 you would multiply 5 and 2 to get the area of 10

area = l x h

5 x 2 = 10 < the answer (10)

Step-by-step explanation:

the amount of space taken up by the cylinder, measured in cubic units ... A cylindrical container is used to hold water. It has a diameter of 30 ... A brand new filled can of chicken broth is 10 cm tall and has a radius of 10 cm. Mishka ... Isabella's Ice Cream Parlor uses waffle cones that are 5 inches in diameter and 6 inches tall.

[tex] \frac{3}{4} + \frac{1}{3}x = 6 [/tex]

Multiply both sides of the equation by 12

[tex]9 + 4x = 72[/tex]

Move constact to the right-hand side and chancge it's sign.

[tex]4x = 72 - 9[/tex]

Subtranct the numbers

While it’s possible to create a dot plot using this data, plotting 50 points on a number line is cumbersome. The more data points there are, the more tedious it is to make a dot plot. For this case, it might be better to use a different visual representation.

Answer:

(A) Population: UCB undergraduates

Sample: The selected 129 UCB undergraduates

(B) Yes, they can be generalized to the population

No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.

Step-by-step explanation:

STUDY: Relationship between socio-economic class and unethical behavior.

The bases for determining social class here are:  money, education, and respected job.

RESULT: Those who identified as upper class took more candy than others.

(A) Identify the population of interest and the sample, in this study.

The population of interest in this study is UCB undergraduates.

The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.

(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.

The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.

Answer:

-2 1/2 is greater

Step-by-step explanation:

-2 1/2 because a half is bigger than a 8th.

Answer:

1st. Problem

Let's solve for x.

25x+15y=17

Step 1: Add -15y to both sides.

25x+15y+−15y=17+−15y

25x=−15y+17

Step 2: Divide both sides by 25.

25x/25 = -15y+17/ 25

x equals...

x= -3/5 y + 17/25

2nd. Problem

Let's solve for x.

25x+15y=305

Step 1: Add -15y to both sides.

25x+15y+−15y=305+−15y

25x=−15y+305

Step 2: Divide both sides by 25.

25zx/25 = -15y305/25

x equals...

x = -3/5 y + 61/5

Answer:

It’s 5,41

Step-by-step explanation:

Answer:

m<GKH + m<HKI = 180; m<HKI + m<IKJ = 180 - Angles forming a linear pair sum to 180

m<GKH + m<HKI = m<HKI + m<IKJ - Subsitution

m<GKH = m<IKJ - Algebra

<GKH ≅ <IKJ - Definition of congruence

Step-by-step explanation:

Angles that form a linear pair are supplementary because together they make a straight line. So, they must sum to 180.

In statement 2, m<HKI + m<IKJ replaces 180 degrees. This is allowed because m<HKI + m<IKJ is equivalent to 180 degrees, so it can be substituted.

In statement 3, m<HKI is subtracted from both sides. This is allowed through the property of equality, which is a part of algebra.

The definition of congruency is that two shapes that are equal are congruent. So if m<GKH = m<IKJ, then they must be congruent as well.
