Answer:
A) y = -3x +7
B) y = (7/3)x
Step-by-step explanation:
Maybe you want the equations of the lines.
Two points are marked on each graph. These can be used to compute the slope. One of them is the y-intercept, so that can be used in the slope-intercept equation.
A) m = (y2 -y1)/(x2 -x1) = (1 -7)/(2 -0) = -3
b = 7
So, the equation y = mx+b is ...
y = -3x +7
__
B) m = (7 -0)/(3 -0) = 7/3
b = 0
The equation is ...
y = (7/3)x

Which ordered pair is in the solution set of the system of inequalities shown in the graph below
The ordered pair is in the solution set of the system of inequalities shown in the graph will be (-2, -1)
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Which three types of transformations result in congruent shapes? Question 8 options: A) Reflection, rotation, translation B) Reflection, translation, dilation C) Reflection, dilation, rotation D) Rotation, dilation, translation
Answer: A
Step-by-step explanation:
Answer:
A. Reflection, rotation, translation
Step-by-step explanation:
Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent. Explore and discuss the examples of transformations below with your child.

Zared plays basketball on his high school team. One of the things he needs to practice is his free throws. On his first shot, there is a probability of 0.6 that he will make the basket. If he makes a basket, his confidence grows and the probability he makes the next shot increases by 0.05. If he misses the shot, the probability he makes the next one decreases by 0.05.
He takes 5 shots. What is the probability he makes at least 3 shots? (Hint: a tree diagram might be a helpful strategy)
Answer:
lol brainliest
Step-by-step explanation:
The probability that he makes at least 3 shots is P{E} = 0.15
What is a probability? Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Given is that Zared plays basketball on his high school team. One of the things he needs to practice is his free throws. On his first shot, there is a probability of 0.6 that he will make the basket. If he makes a basket, his confidence grows and the probability he makes the next shot increases by 0.05. If he misses the shot, the probability he makes the next one decreases by 0.05.
If he takes 5 shots, than the probability that he makes at least 3 shots is-
P{E} = 5 x 0.05 - 2 x 0.05
P{E} = 0.25 - 0.1
P{E} = 0.15
Therefore, the probability that he makes at least 3 shots is P{E} = 0.15.

Step-by-step explanation:
Count up for Y and count to the left for X
Answer:
(x, y ) → (x - 10, y + 7 )
Step-by-step explanation:
Consider the coordinates of W and W'
W ( 1, - 2 ) and W'(- 9, 5 )
Consider the x- direction from W to W'
1 → - 9 = - 9 - 1 = - 10
Consider the y- direction from W to W'
- 2 → 5 = 5 - (- 2) = 5 + 2 = + 7
Thus the translation rule is
(x, y ) → ( x - 10, y + 7 )

Step-by-step explanation:
I'll go over #7 and you should be able to do the rest.
Slope intercept form general equation is:
y = mx + b
I bolded the value you need to change/find.
m is the slope
b is the y-intercept
You can calculate m using:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
you're given (-4,-4) and (0,5) so y₂=5, y₁=-4, x₂=0, x₁=-4
[tex]m=\frac{5-(-4)}{0-(-4)}=9/4[/tex]
Plug your value into the point-slope formula.
[tex]y = m(x-x_1)+y_1[/tex]
[tex]y = (9/4)(x-(-4))+(-4)[/tex] simplify it
[tex]y= 9/4x+5[/tex] the simplified form is the slope-intercept formula
A phone company offers two monthly plans. Plan A costs $21 plus an additional $0.09 for each minute of calls. Plan B has no initial fee but costs $0.13 for each minute of calls.
For what amount of calling do the two plans cost the same?
minutes
What is the cost when the two plans cost the same?
$
Answer:
525; $68.25
Step-by-step explanation:
21+.09x=.13x
x=525
21+.09(525)=68.25
.13(525)=68.25
The answers are :
A) The amount of calling for which the two plans cost the same will be 525 minutes.
B) The cost when two plans cost the same amount is $68.25.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
A)
Let's assume the amount of calling is x for which the two plans cost the same.
So , the algebraic expression can be written as ;
Plan A = Plan B
or
21 + (0.09 × x) = 0 + (0.13 × x)
Solving this we will get amount of calling for which the two plans cost the same as :
21 = 0.13x - 0.09x
0.04x = 21
x = 525 minutes
B)
Now , the cost when two plans cost the same amount :
Plan A = 21 + (0.09 × 525) = 21 + 47.25 = $68.25
or
Plan A = Plan B = $68.25
Therefore , the answers are :
A) The amount of calling for which the two plans cost the same will be 525 minutes.
B) The cost when two plans cost the same amount is $68.25.

Which of the following must be true for the parallelogram shown below?
Answer:
We conclude that:
Option D i.e. m∠DAB = m∠BCD is correct option.
Step-by-step explanation:
We know that a Parallelogram is a quadrilateral with two pairs of parallel sides.
We also know that the opposite angles of a parallelogram are equal.
Given
m∠DABm∠BCDFrom the figure:
It is clear that m∠DAB is the opposite angle of m∠BCD.
Thus,
m∠DAB = m∠BCD ∵ opposite angles of a parallelogram are equal.
Therefore, we conclude that:
Option D i.e. m∠DAB = m∠BCD is correct option.

2. A coin is tossed, then a
letter from the word
INDIANAPOLIS is selected at
random. Find each
probability.
The probability are for P(h) = 1/2, P(t) = 1/2, P(getting letter P) = 1/12, P(getting a vowel) = 1/2, P(tails then a vowel) = 1/4, P(tails then N) = 1/12, P(heads then D or I) = 1/6.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a coin tossed, then a letter from the word INDIANAPOLIS is selected at random.
Probability for getting head or tell:
P(h) = 1/2
P(t) = 1/2
The word INDIANAPOLIS has 12 letters with 3I's, 2A's, 2N's, 1D's, 1P's, 1L's, 1O's, and 1S's
Probability for getting letter P:
P(getting letter P) = 1/12
P(heads, then letter P) = P(heads)×P(getting P) = (1/2)(1/12) = 1/24
P(tails) = 1/2
P(getting a vowel) = 6/12 = 1/2
P(tails then a vowel) = (1/2)(1/2) = 1/4
P(tails then N) = (1/2)(2/12) = 1/12
P(heads then D or I) = (1/2)(4/12) = 4/24 = 1/6
Thus, the probability are for P(h) = 1/2, P(t) = 1/2, P(getting letter P) = 1/12, P(getting a vowel) = 1/2, P(tails then a vowel) = 1/4, P(tails then N) = 1/12, P(heads then D or I) = 1/6.
