If the slope of y=2x+5 is changed to -2, how does the graph change?
The positive graph of y = 2x + 5 changes to the negative graph which moves downward from left to right when the slope is changed to -2.
What is Slope?Slope of a line is defined as the difference in the y coordinates divided by the difference in the x coordinates of two points.
Slope of a line is usually denoted by the letter m.
First let us take the graph of y = 2x + 5.
Take x intercept and y intercept of this graph.
x intercept is the point where line touches X axis and y intercept is the point where line touches Y axis.
From the equation of the line, y intercept = 5
So we get a point (0, 5)
Now to find x intercept, let y = 0 in the equation, then x = -2.5
So we get another point (-2.5, 0)
So the line y = 2x + 5 passes through the points (0, 5) and (-2.5, 0).
Now if the slope changed to -2, equation becomes y = -2x + 5.
y intercept is same.
So one point of the line will be (0, 5)
To find x intercept, let y = 0 in the second equation, then x = 2.5
So the second line passes through the points (0, 5) and (2.5, 0)
That is, the graph which goes upward from left to right changed to the graph downward from left to right.
Hence, when the slope changed to -2, the graph goes downward from left to right.

A card is drawn from an ordinary deck of cards. What is the probability that the card is a king given that the card is red?
A. P(K|R) = 0.8
B. P(K|R) = 0.2
C. P(K|R) = 0.92
D. P(K|R) = 0.08
Answer:
d. 0.08
Step-by-step explanation:
52 cards in a deck of cards. 26 are red. there are 2 red kings. 2/26= 0.076 which rounds up to 0.08
Half the cards (26) are red
Then there are 2 red kings out of the 26.
Probability of picking a red king out of the red cards is 2/26 = 1/13 = 0.076
Round to 0.08

Amanda is practicing her dives off the diving board. When she dives into the water, the path her body makes and where she resurfaces can be modeled by the equation 0=2−8+7 where is the number of horizontal feet she travels. Solve the equation to find the number of feet she will travel before coming back to the surface of the water.
Answer:
The number of feet she will travel back is 1 or 7 feet
Step-by-step explanation:
Here, we need to solve the quadratic equation
That will be as follows;
0 = x^2 -8x + 7
x^2-x-7x+ 7 = 0
x(x-1)-7(x-1) = 0
(x-1)(x-7) = 0
x = 1 or 7
The number of feet she will travel before coming back to the surface of the water is 1 or 7 feet

The ratio of income Mr. John to his expenditure is 8 : 7. If his expenditure of one year is ₹ 1,26,000, what is his monthly income?
Answer:
₹ 12000 .
Step-by-step explanation:
It is given that,
The ratio of income Mr. John to his expenditure is 8 : 7
Expenditure = ₹ 1,26,000
Let the income is 8x and expenditure is 7x.
ATQ,
7x = 1,26,000
x = ₹ 18000
Yearly income = 8x
= 8(18000 )
= ₹ 144000
Monthly income,
[tex]M=\dfrac{144000}{12}\\\\=12000[/tex]
Hence, his monthly income is ₹ 12000 .

10. A ladder 6.5 metres long leans against a wall,
touching a window sill, and makes an angle of
62° with the ground. Find the height of the
window sill above the ground. How far is the
foot of the ladder from the foot of the wall?
Answer:
5.74m, 3.05m
Step-by-step explanation:
The set up is a right angled triangle.
Length of the ladder is the hypotenuse = 6.5m
Angle of elevation = 62°
Required
Height of the window (opposite)
Using SOH CAH TOA trigonometry identity
Sin theta = opp/hyp
Sin62 = opp/6.5
Opp = 6.5sin62
Opp = 5.74m
Hence the height of the window is 5.74m
The distance of the ladder from the foot of the wall is the adjacent
Cos 62 = adj/6.5
adj = 6.5cos62
adj = 3.05m
Hence the distance of the ladder from the foot of the wall is 3.05m

Step-by-step explanation:
This question can be solved but if your asking about equation 33 = k - 15 is it, because 33 is the total and 15 is less than k, whenever you see less than the number before is always the number telling the other number to subtract, such as 44 is 16 less than a number, the answer will be 44 = x - 16.

Henry rode his motorcycle from his house to a friend's house. After riding 10 miles, he realizes he has traveled 2/3 of the way. How far is Bob's house from his friend's house?
A. 20 miles
B. 15 miles
C. 12 miles
D. 25 miles
Step-by-step explanation:
2/3 of diatance = 10 miles
3/3 of distance = 10 * (3/2) = 15 miles.
The distance between the houses is 15 miles. (B)
Let the total distance covered= x
Distance covered= 10 miles
According to the question,
2/3 of x= 10
=> 2/3 × x= 10
=> 2x/3= 10
=> 2x= 10× 3
=> 2x= 30
=> x= 30/2
=> x= 15
Bob's house is 15 miles away from Henry's house.
