Convert the following equation into
slope-intercept form
4x - 6y = 42
Answer:
y=2/3x -7
Step-by-step explanation:
4x -6y=42
-4x = -4x +42
-6y= -4x + 42
-6 -6 -6 divide both sides by -6
y= 4/6x -7 simplify
y= 2/3x -7

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting at least 1 red?
Answer:
There are 6+5 marbles.
Of those, 5 are red.
The chances of drawing a red marble are 5/11
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time
5/11*5/11=25/121

Decrease $820 by 32%
Answer:
557.6
Step-by-step explanation:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
32% = 32/100 = 32 ÷ 100 = 0.32.
100% = 100/100 = 100 ÷ 100 = 1.
Percentage decrease = 32% × 820
New value =
820 - Percentage decrease =
820 - (32% × 820) =
820 - 32% × 820 =
(1 - 32%) × 820 =
(100% - 32%) × 820 =
68% × 820 =
68 ÷ 100 × 820 =

Step-by-step explanation:
Use the Pythagorean theorem to find each missing length to the nearest tenth
Answer:
c (the hypotenuse) = 10.4 units
Step-by-step explanation:
Start off by rearranging the original pythangorean theorem (a^2+b^2=c^2) by taking the square root of both sides so it is in the form of a distance formula solving for c(the hypotenuse).
c^2 will become |c| as length cannot be negative so (labeling an absolute value is negligible)
a^2+b^2 = c^2
c^2 = a^2+b^2
√(c^2) = √(a^2+b^2)
c = √(a^2+b^2)
Then substitute the given lengths, in this scenario, sides a and b.
After you substitute, just simplify.
c = √(3^2+10^2) = √(9+100) = √109 ≈ 10.4 units (nearest tenth)
this month, Carla caught the following fish in lake George: 24 trout, 41 sunfish, 12 perch, and 23 bluegills. If Carla catches another fish this month , what's the probability of her catching a trout
Answer:
I believe the answer is about 1/2!
Step-by-step explanation:
I don't have a step-by-step but when I took a test this question was on it and I got the question right by putting about 1/2!
The probability of her catching a trout is 6/25
What is probability ?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
According to the question
based on given condition , formulate
24 ÷ (23 + 12 + 24 + 41)
Calculate sum or difference = 24/23 + 12 + 24 + 41
Calculate sum or difference = 24/59 + 41
Calculate sum or difference = 24/100
Reduce the fraction = 6/25
Hence, the probability of her catching a trout is 6/25

Find the zeros of the function algebraically.
f(x) = 16x4 − 49x2
Answer: Plz mark me brainlest
Step-by-step explanation:
Just Simply Use Identity:
a^2 - b^2 = ( a+b) ( a-b)
Then:
( 49X^4 - 36 X^2) = 0
(7 X^2 + 6 X) ( 7X^2 - 6X) =0
7X^2 + 6X = 0, then X( 7X +6) =0 X=0, 7x +6 =0 X = -6/7
7X^2 -6x =0 X( 7x - 6) =0 X =0 7x -6 =0 X =6/7
Pull out a factor of x² from f(x) :
16x⁴ - 49x² = x² (16x² - 49)
Now write it as a difference of squares, then factorize:
16x⁴ - 49x² = x² ((4x)² - 7²)
16x⁴ - 49x² = x² (4x - 7) (4x + 7)
Set this equal to 0 and solve for x :
x² (4x - 7) (4x + 7) = 0
x² = 0 or 4x - 7 = 0 or 4x + 7 = 0
x = 0 or x = 7/4 or x = -7/4

∠4
Answer:
3, 8, 6
Step-by-step explanation:
Please correct me if I am wrong!
The angles that have the same measure as angle 1 are ∠3, ∠6 and ∠8.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
A traversal line cuts two parallel lines.
So, ∠1 = ∠6. {From the property of opposite angles}.
And ∠1 = ∠3. {From the property of alternate interior angles}.
The property of opposite angles,
∠8 = ∠3.
So, the angle measures that are equal to ∠1 are:
∠3, ∠6 and ∠8.
Therefore, ∠3, ∠6 and ∠8 are the equal angle measures.
