ASAPPP What is the slope of the line represented by the equation y
3?
-3
4
o
O
The slope of the line represented by this equation is 4/5.
We know this because this line is in slope-intercept form, y=mx+b, where m represents the slope and b represents the y-intercept. Thus, we can conclude that the slope is 4/5, which means that for every 4 units the line moves up, it also moves 5 units over (because slope is defined as rise/run).
This equation is in slope-intercept form, or
y = mx + b where m is the slope and b is the y-intercept. The number in the m position in our equation is 4/5, so the slope is 4/5

solve for x, x+3y=-3
Answer:
x = -3y-3
Step-by-step explanation:
To put the equation in terms of x, you simply subtract 3y on both sides.
Answer:
x = -3 -3y
Step-by-step explanation:
x+3y=-3
Subtract 3y from each side
x+3y-3y=-3-3y
x = -3 -3y

In the diagram, point P is a point of tangency. Find the radius r of circle O.
Answer:
r = 12
Step-by-step explanation:
From the figure attached,
QP is a tangent to the circle O at the point P.
Therefore, by the property of tangency,
OP ⊥ QP
By applying Pythagoras theorem In right triangle QPO,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
(OQ)² = (OP)² + (PQ)²
(25 + r)² = (35)² + r²
625 + r² + 50r = 1225 + r²
50r = 1225 - 625
50r = 600
r = 12
Therefore, r = 12 units is the answer.

r=12

Step-by-step explanation:
The expression can be rewritten as b + 1/8 + c
substitute b and c
2 + 1/8 - 7/4 = 16/8 + 1/8 - 14/8 = 3/8
Answer:
3/8
Step-by-step explanation:
b - (-1/8) +c
Subtracting a negative is adding
b+1/8+c
Let b =2 and c = -7/4
2+1/8 - 7/4
2 1/8 - 7/4
Getting a common denominator
2 1/8 - 7/4*2/2

Changing to an improper fraction
17/8 - 14/8

The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains point (4, 5)?
y = −2x + 13
y = negative one halfx + 7
y = negative one halfx + 3
y = −2x − 3
Answer:
y = −2x + 13
Step-by-step explanation:
equation of line slope intercept form is y = mx +c
where m is slope and c is y intercept
when two lines are parallel then their slope are equal.
_______________________________________
Given line
CD
y = −2x − 2
it is in form of y = mx +c
thus, m = -2
Given that other line parallel to CD y = −2x − 2
Thus, its slope will be -2.
Let the equation of required line be
y = mx +c (as slope will be -2)
Then equation of line will be
y = -2x +c
Given that this line contains (4,5) it will satisfy the equation y = -2x+c
using x = 4 and y = 5
we have
y = -2x +c
5 = -2*4 + c
=> 5 = -8 + c
=> c = 5+8 = 13
Thus, equation of line parallel to y = −2x − 2 and containing point(4,5) is
y = −2x + 13
Answer:
A. y = −2x + 13

You are going discount shopping for some new sweaters, T-shirts, and pants. Sweaters (s) cost $5, T-shirts (t) cost $8, and pants (p) cost $2. What algebraic expression models the total cost of clothes that you buy?
Suppose you bought 24 sweaters, 6 T-shirts, and 17 pairs of pants. How much did you spend?
Answer:
24s + 6t + 17p= 202
Step-by-step explanation:
Answer:
24x + 6y + 17z = 202
Step-by-step explanation:
Let sweaters be x
T-shirt be y
Pant be z
The equation is 24x + 6y + 17z
Substituting with the cost of each,
24(5) + 6(8) + 17(2)
120 + 48 + 34 = 202
Which statements are true about reflections? Check all that apply.
An image created by a reflection will always be congruent to its pre-image.
An image and its pre-image are always the same distance from the line of reflection.
If a point on the pre-image lies on the line of reflection, the image of that point is the same as the pre-image.
The line of reflection is perpendicular to the line segments connecting corresponding vertices.
The line segments connecting corresponding vertices are all congruent to each other.
The line segments connecting corresponding vertices are all parallel to each other.
Answer:
A, B, C, D, F
Step-by-step explanation:
A. An image created by a reflection will always be congruent to its pre-image.
Congruent means identical or similar. The orientation, size, and shape of the pre-image are not changed after a reflection- therefore, the pre-image and image are congruent.
B. An image and its pre-image are always the same distance from the line of reflection.
When a pre-image is flipped across the line of reflection, both figures are perfectly symmetrical. Nothing has changed aside from orientation and location on the graph. The number of units between the figures and the line of reflection should remain unchanged.
C. If a point on the pre-image lies on the line of reflection, the image of that point is the same as the pre-image.
When you reflect a pre-image with a point that lies on the line of reflection, that point will stay on the line of the reflection as the rest of the figure is flipped.
I will explain these two answers together since they have similar explanations.
D. The line of reflection is perpendicular to the line segments connecting corresponding vertices.
F. The line segments connecting corresponding vertices are all parallel to each other.
In a reflection, the horizontal or vertical (depending on the line of reflection, y-axis or x-axis) coordinates are altered. However, if one were to draw an imaginary line connecting the corresponding vertices, both the image and pre-image are parallel and perpendicular.
I hope this helped, good luck on your work/test!

Neil is making colorful friendship bracelets for 6 of his friends. He has all of the colors of
thread he plans to use except for green. If every bracelet uses 22 inches of each color of
thread, how many feet of green thread should Neil buy from the craft store?
Answer:
11 feet(or 132 inches)
Step-by-step explanation:
Since there are 6 bracelets to make, we can multiply 22 and 6 to get 132.
The correct unit / format to answer this is in feet and all we have right now is the amount of inches we must convert.
132 inches converted into feet can be found by dividing by the amount of inches there are in a 1 foot.
Since there are 12 inches in a foot, we can divide 132 by 12 to get 11.

4/7 divided by 7/2?????
Answer:
8/49
Step-by-step explanation:
4/7 ÷7/2
Copy dot flip
4/7 * 2/7
Multiply the numerators
4*2 = 8
Multiply the denominators
7*7= 49
numerator over denominator
8/49
Answer: 8/49
Step-by-step explanation: When dividing by a fraction, we can change the division sign to multiplication and flip the second fraction.
So 4/7 ÷ 7/2 means the same thing as 4/7 · 2/7.
So when dividing by a fraction, we can just multiply by the
reciprocal of that fraction or that fraction flipped.
Now multiply across the numerators
and denominators to get 8/49.
Since 8/49 is in lowest terms, it's our final answer.

--------------- = --------------
2 bowls 7 bowls
Using cross products
18*7 = 2x
Divide by 2
18/2 *7 = x
63 minutes
Answer: 63 minutes or 1 hour and 3 minutes
Step-by-step explanation:
18 minutes is how long it takes to make 2 bowls. To find out how long it takes to make 1 bowl, divide by 2.
18 / 2 = 9
Now multiply that by 7 to find out how long it takes to make 7 bowls.

Tessa bought stock in a restaurant for $178.00. Her stock is now worth $256.32. What is the percentage increase of the value of Tessa‘a stock?
Answer: 44%
Step-by-step explanation:
Cost of stock = 178
Present value = 256.32
Increase in value = 78.32
= 78.32/178 x 100 = 44%
Answer:
44%
Step-by-step explanation:
Well first you have the starting value $178 and the new value $256.32.
So 256.32 - 178 is 78.32.
So our fraction is 78.32/178.
So we divide them which is .44.
And we have to make a percent which is 44%.
