(i)y, when x=2
(ii)x, when y=5
Answers
Answer:
When x = 2, y = 0When y = 5, x = 4Step-by-step explanation:
PART I: Value of y, when x = 2Given information
x = 2
Given expression
2y - 5x + 10 = 0
Substitute values into the expression
2y - 5(2) + 10 = 0
Simplify by multiplication
2y - 10 + 10 = 0
2y = 0
Divide 2 on both sides
2y / 2 = 0 / 2
[tex]\boxed{y=0}[/tex]
-----------------------------------------------------------------
PART II: Value of x, when y = 5Given information
y = 5
Given expression
2y - 5x + 10 = 0
Substitute values into the expression
2(5) - 5x + 10 = 0
Simplify by multiplication
10 - 5x + 10 = 0
20 - 5x = 0
Add 5x on both sides
20 - 5x + 5x = 0 + 5x
20 = 5x
Divide 5 on both sides
20 / 5 = 5x / 5

Please let me know if you have any questions
Answer:
(i) x = 2
Substituting value in the equation,
2y - 5(2) + 10 = 0
2y - 10 + 10 = 0
2y = 0
y = 0
(ii) y = 5
Substituting value in the equation,
2(5) - 5x + 10 = 0
10 - 5x + 10 = 0
20 - 5x = 0
20 = 5x
5x = 20
x = 20/5

solve for x in the problem below and show all work
7x - 5x/3 (20/x - 8) -48=0
Answers
Let’s work this out step by step.
The first thing you want to do is move that 48 to the other side. To do that, add 48 to both sides:
7x-5x/3(20x-8)=48
Now, the equation isn’t equal to zero… so it is solvable! Remember in order of operations: PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction. So, let’s start by multiplying the (-5x/3) by the components inside the parentheses to get rid of the parentheses altogether!
7x-100x/3x+40x/3=48
Since both the numerator and denominator have an “x” in them in “100x/3x”, you can cancel out the “x”s to just get 100/3, which is 33.333333
7x-100/3+40x/3=48
Let’s get rid of that 100/3 by adding it to both sides.
7x+40x/3=81.33333333333
Transform 7x to a fraction that can be added to 40x/3 (common denominators)
7x=7x/1
7x/1* (3/3)= 21x/3
Now, add the two fractions together
21x/3+40x/3= 61x/3
61x/3=81.333333333
Get rid of the 3 by multiplying on both sides:
61x= 244
Divide by 61 to get x
X=4

3.
Answers
Answer:
he arithmetic sequence ai is defined by the formula: a1= 2 ai= ai - 1 -3 find the sum of the first 335 terms in the sequence
Step-by-step explanation:
In an arithmetic sequence,
a_1=2a
1
=2
a_i=a_{i-1}-3a
i
=a
i−1
−3
To find:
The sum of the first 335 terms in the given sequence.
Solution:
The recursive formula of an arithmetic sequence is:
a_i=a_{i-1}+da
i
=a
i−1
+d ...(i)
Where, d is the common difference.
We have,
a_i=a_{i-1}-3a
i
=a
i−1
−3 ...(ii)
On comparing (i) and (ii), we get
d=-3d=−3
The sum of first i terms of an arithmetic sequence is:
S_i=\dfrac{i}{2}[2a+(i-1)d]S
i
=
2
i
[2a+(i−1)d]
Putting i=335,a=2,d=-3i=335,a=2,d=−3 , we get
S_{335}=\dfrac{335}{2}[2(2)+(335-1)(-3)]S
335
=
2
335
[2(2)+(335−1)(−3)]
S_{335}=\dfrac{335}{2}[4+(334)(-3)]S
335
=
2
335
[4+(334)(−3)]
S_{335}=\dfrac{335}{2}[4-1002]S
335
=
2
335
[4−1002]
S_{335}=\dfrac{335}{2}(-998)S
335
=
2
335
(−998)
On further simplification, we get
S_{335}=335\times (-499)S
335
=335×(−499)
S_{335}=-167165S
335
=−167165
Therefore, the sum of the first 335 terms in the given sequence is -167165.
2. What might be a problem with using interval lengths that are too small?
Answers
A major problem with interval lengths that are too small is that it masks the shape of the distribution.
The interval length used in a distribution may be described as the size of the class or the class width. The interval length is usually important when drawing histograms and other related graphs for a grouped distribution.
The most significant effect of using a class interval which is too small is that it masks the actual shape of distribution, Hence preventing it from being distinct.
For best practice, it is essential that the class interval is of moderate width, hence enabling us to have a distribution which isn't maksed nor exaggerated.

Changing back to a mixed number
x≥ 21 2/3
Answer:
Answer: A
Step-by-step explanation:
[tex]81 - 1 \frac{1}{5} x \leqslant 55[/tex]
subtract 81 from both sides:
[tex](81 - 1 \frac{1}{5} x) - 81 \leqslant 55 - 81 \\ \\ - 1 \frac{1}{5} x \leqslant - 26[/tex]
express the mixed fraction into a proper fraction:

multiply -5 on both sides:
[tex] ( - \frac{6}{5} x) \times 5 \leqslant ( - 26 \times - 5) \\ \\ 6x \leqslant 130[/tex]
divide all sides by 6:
[tex] \frac{6x}{6} \leqslant \frac{130}{6} \\ \\ x \leqslant 21 \frac{2}{3} [/tex]
How do you factorise with letters and numbers please explain clearly example
7ab+14b how do I put that in brackets and what are the rules when factoring
Answers
Answer:
7b(a+2)
Step-by-step explanation:
First. look at the coefficient. See if they are common multiple of some number. If so find the GCF between them.
Then find the variable both terms share.
Put the GCF coeffiecnt and the variable both terms share outside the parentheses.
Inside the parenthesis will be a term that multiplied by the term outside of the parenthesis will equal the original equation.
For example, 7ab+14b.
Set up equation.
[tex]7ab + 14b[/tex]
Both terms share a b variable and 7 and 14 GCF is 7 so
let factor out 7b.
[tex]7b(a + 2)[/tex]
Why is inside the parenthesis is the term (a+2). If we divide 7ab+14b by 7b separately we get
[tex]a + 2[/tex]

A recipe for fluffy slime calls for 3 3/4 cups of shaving

would you need if you were making enough slime

Answers
Answer:
75/4 cups (or 18-3/4 cups)
Step-by-step explanation:
2 people ---> requires 3 3/4 cups (or 15/4 cups) of shaving cream
10 people ----> requires 5 times the amount of shaving cream needed for 2 people
Hence shaving cream is needed for 10 people
= 5 x 3 3/4 cups
= 5 x 15/4 cups
= 75/4 cups (or 18-3/4 cups)

What is the equation of the line that passes through the point (8,1) and has a slope
of –3/4?
Answers
Answer:
[tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is already given as [tex]-\frac{3}{4}[/tex] so all we have to do is solve for y-intercept
First, write the equation in slope-intercept form
[tex]y=-\frac{3}{4}x+b[/tex]
Next, use the point to substitute the x and y value and solve for the y-intercept
[tex]y=-\frac{3}{4} x+b[/tex] where b = y-intercept
point: (8, 1)
[tex]1=-\frac{3}{4}(8)+b[/tex]
Then multiply 8 and -3/4
[tex]1=-6+b[/tex]
Finally, solve for the b (y-intercept)
b = [tex]1--6[/tex]
b = 7
so the y-intercept is 7
And the equation of the line that passes through the point (8, 1) and has a slope of -3/4 is [tex]y=-\frac{3}{4}x+7[/tex]
