For the equation 8x + 2y = 16 What is the slope? What is the y-intercept (write as an ordered pair)? What is the x-intercept (write as an ordered pair)?
Answer:
Step-by-step explanation:
8x+2y=16
2y=-8x+16
y=-4x+8
slope is -4
y-intercept is (0,8)
x-intercept is (2,0)
Answer:
slope = -4
y-intercept = (0,8)
x-intercept = (2,0)
Step-by-step explanation:
To find the slope:
8x + 2y = 16. First get the y by itself.
2y = -8x + 16. Then divide by 2
y = -4x + 8. So the slope is -4.
y-intercept:
8x+2y=16
8(0)+2y=16
2y=16
y=8
y-int: (0,8)
x-intercept:
8x+2y=16
8x+2(0)=16
8x=16
x=2
x-int: (2,0)

Solution Steps:______________________________
1.) [tex]\bold{\frac{x}{-7.2}=-4}[/tex]:
- Multiply both sides by −7.2:
[tex]-7.2[/tex] × [tex]-7.2=[/tex] Cancels Out[tex]-4[/tex] × [tex]-7.2=28.8[/tex]So your answer is [tex]\bold{x=28.8}[/tex].
2.) [tex]\bold{\frac{3}{2}x=6}[/tex]:- Find the reciprocal and multiply by that on each side:
The reciprocal is [tex]\frac{2}{3},(3*2=6,~2*3=6)[/tex][tex]\frac{3}{2}[/tex] turns into [tex]\frac{2}{3}[/tex][tex]6[/tex] × [tex]\frac{2}{3}=\frac{12}{3}[/tex]- Divide the numerator by the denominator:
[tex]12[/tex] ÷ [tex]3=4[/tex]So your answer is [tex]\bold{x=4}[/tex].
3.) [tex]\bold{\frac{x}{2}=-4}[/tex]:- Multiply both sides by 2:
[tex]\frac{x}{2}[/tex] × [tex]2=x[/tex][tex]-4[/tex] × [tex]2=-8[/tex]So your answer is [tex]\bold{x=-8}[/tex].

Thirty percent of Irma’s Boutique’s sales came from leggings. They sold $390 worth of leggings last week. What were the total sales for the Boutique last week?
Answer:
The total sales of Boutique last week = $1300
Step-by-step explanation:
Given that:
Percent of sales came from leggings = 30%
Worth of leggings sold = $390
Let,
x be the total sales in the week.
30% of x = 390
[tex]\frac{30}{100}x=390[/tex]
0.3x = 390
Dividing both sides by 0.3
[tex]\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300[/tex]
Hence,
The total sales of Boutique last week = $1300
In the figure shown, ABCD is a square and triangle CDE is equilateral. What is the degree measure of angle CBE?
Answer:
angle CBE=15 degrees
Step-by-step explanation:
angle ECD is 60 degrees and EC=CD because equilateral triangle
angle DCB is 90 degrees and CB=CD because square
angle ECD +angle DCB= angle ECB
60+90=150=angle ECB
since triangle ECB has legs EC and CB equal in length, then it is an isosceles triangle.
so angles CBB and CBE are equal
angle CBE=(180-150)/2
angle CBE=15 degrees
Answer:
15 degrees
Step-by-step explanation:
Since triangle CDE is a equilateral triangle then all the sides and angles are congruent DC=CE=ED, ∠DEC=∠ECD=∠CDE=60 degrees
since line CD is also a side of the square and all sides of a square are congruent therefore DC=CB=BA=AD
therefore side BC is equal to side CE which means CBE is an isosceles triangle then angles ∠BEC and ∠CBE are congruent
Then in order to figure out angle ∠CBE we need to find ∠ECB
and ∠ECB=∠DCE+∠DCB
∠DCE= 60 degrees because it's a equilateral triangle
∠DCB=90 degrees because it's a square
therefore ∠ECB=150 degrees
all angles of a triangle = 180 degrees
∠BEC + ∠CBE + ∠ECB = 180
since ∠BEC is congruent to ∠CBE i can substitute ∠BEC for ∠CBE
2(∠CBE) + 150 =180
2(∠CBE)=30
∠CBE=15

Is there a solution YES OR NO AND WHAT IS THE SOLUTION?
Answer:
(-1, -2) will be the solution.
Step-by-step explanation:
System of equations has been given as,
y = 3x + 1 ---------(1)
Input-output value table for the given line will be,
x -2 -1 0 1
y -5 -2 1 4
y = -x - 3 ----------(2)
Input-output value table for the given line will be,
x -2 -1 0 1
y -1 -2 -3 -4
By plotting the given coordinates we can draw the straight lines.
And the point of intersection (common point) of these lines will be the solution of the given system of equations.
Hence, (-1, -2) will be the solution.

Answer:
Option B: x = 15 is a solution, but x = 9 is not is the correct answer.
Step-by-step explanation:
Given equation is:
x - 3 = 12
The solutions we have to check are;
x = 9 and x = 15
Putting x = 9 in the given equation;
9 - 3 = 12
6 ≠ 12
Putting x = 15 in the given equation;
15 - 3 = 12
12 = 12
Hence,
Option B: x = 15 is a solution, but x = 9 is not is the correct answer.
answers for the 2 boxes please :)
Step-by-step explanation:
2x - 3y = 25
+ (5x + 3y = 10)
=> 7x = 35, x = 5.
Therefore 2(5) - 3y = 25, 3y = -15, y = -5.
The solution pair is (5,-5).
Answer:
x = 5
y = -5
so values in boxes = (5, -5)
answers for the 2 boxes please :)
Answer:
(0, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 9 → (1)
- 2x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the x- term
2x + 6y = 18 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 + 8y = 24
8y = 24 ( divide both sides by 8 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 3(3) = 9
x + 9 = 9 ( subtract 9 from both sides )
x = 0
solution is (0, 3 )
There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 blue?
Answer: The probability is 0.536
Step-by-step explanation:
We have 3 blue marbles, and 5 red marbles (a total of 3 + 5 = 8 marbles)
First, we take a marble and it is not replaced.
Then we take another marble.
We want to calculate the probability of getting only one blue marble.
Then we have two cases:
1) First we take a blue marble, and after a red marble
2) First we take a red marble, and after a blue marble.
Let's calculate the probability of these two events:
1) The probability of taking a blue marble at random, is equal to the quotient between the number of blue marbles, and the total number of marbles.
this is: p1 = 3/8.
Now we need to take a red marble. Same procedure as before, but now we already taken a marble from the bag, so the total number of marbles is 7 now, and the number of red marbles is 5. The probability here is:
p2 = 5/7
The joint probability (the probability of both events happening) is equal to the product between the individual probabilities, this is:
P = p1*p2 = (3/8)*(5/7) = 0.268
2) Now we first take a red marble, we can calculate the probabilities in the same way than above.
The probability of taking a red marble at first is:
q1 = 5/8
The probability of taking a blue marble in the second draw is:
q2 = 3/7
The joint probability is:
Q = p1*p2 = (5/8)*(3/7) = 0.268
The total probability of getting only one blue marble will be equal to the addition of both the probabilities we found.
Probability = P + Q = 0.268 + 0.268 = 0.536
