Answer:
26/35
Step-by-step explanation:
6/35+4/7
you need to make the second fraction have the same denominator
to do this, you need to do 7 times 5 to make 35
times the numerator by the same
this would mean:
6/35+20/35=26/35

1. Find a line that is parallel to f(x) = 2x +3 and passes through (0,-4).
2. Find through line that is perpendicular to f(x) = 2x+3 and passes through (0,-4)
Answer:
1)The equation of the Parallel line is 2x -y -4=0
2) The equation of the perpendicular line of the given line x+2y+8=0
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x+3 and passes through (0,-4)
Let y =f(x) = 2x+3
y = 2x+3
⇒ 2x -y +3=0
The equation of the parallel line of the given line 2x - y +k =0
This line is passes through the point (0,-4)
⇒ 2 (0) -(-4)+k=0
4 +k=0
⇒ k =-4
The equation of the Parallel line is 2x -y -4=0
2)
Step(ii):-
Given function f(x) = 2x+3
Let y = 2 x + 3
2x - y +3=0
The equation of the perpendicular line bx -ay +k=0
The equation of the perpendicular line of the given line -x-2y +k =0
This line is passes through the point (0,-4)
⇒ (0) -2(-4)+k=0
8 +k=0
⇒ k =-8
The equation of the perpendicular line of the given line -x-2y -8 =0
The equation of the perpendicular line of the given line x+2y+8=0

C

D

Step-by-step explanation:
For every increase in the x-value by 1,
the y-value decreases by -2.
(From 3 to 1 and from 1 to -1)
Hence, slope of line k
= Rise/Run = (-2)/1 = -2. (A)
Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.
Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.
In this problem, two of the points are: (1,3) and (2,1).
Hence, applying the division:
[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]
The slope of the line is of -2, hence option A is correct.

Hank made 6 out of 8 foul shots ,while Nelly made 8 out of 20 foul shots (A) Who scored the most baskets? (B) Compare Hank and Nelly to determine whose son is more accurate
Answer:
(A) Hank
(B) Hank
Step-by-step explanation:
Hank made 6 out of 8 foul shots Nelly made 8 out of 20 foul shots
(A) Who scored the most baskets?
Converting the shots to decimal
Hank = 6/8 = 3/4 = 0.75
Nelly = 8/20 = 1/4 = 0.40
The person who scored the most baskets is Hank
(B) Compare Hank and Nelly to determine whose son is more accurate
Determining who is more accurate,
Hank = 6/8 = 3/4
This means out of every 4 shots, Hank scored 3
Nelly = 8/20 = 1/4
This means out of every 4 shots, Nelly scored 1
Therefore, Hank is more accurate

BC = 36; D = 15. What is the value of BD - AC.
B
A
BD - AC =
Answer:
BD - AC = 0
Step-by-step explanation:
Given that:
BC = 36 , CD = 15 and BD = x
As these are forming right angled triangle,
Using Pythagorean theorem,
[tex](BD)^2+(CD)^2=x^2\\(36)^2+(15)^2 = x^2\\1296 + 225 = x^2\\1521 = x^2\\[/tex]
Taking square root on both sides
[tex]\sqrt{x^2}=\sqrt{1521}\\x=39[/tex]
As the given shape is rectangular, the sides parallel to each other will have same values.
AB = 15 , AD = 36 and AC = x
[tex](15)^2+(36)^2 = x^2 \\225 + 1296 = x^2 \\1521 = x^2 \\x = 39[/tex]
Now,
BD - AC = 39 - 39 = 0
Hence,
BD - AC = 0

URGENT: A grocer has 150 kg of walnuts that sell for $6 per kg. She plans to add almonds that sell for $5.30 per kg to the walnuts to make a mixture that sells for $5.50 per kg. How many kg of almonds should she add? (MUST SHOW WORK)
Answer:
let c = cashew pounds, w = walnut pounds, m = mixed pounds
Here's what we know:
c + w = m
7c + 5.5w = 6.50m
m = 35
So we now have:
c + w = 35
7c + 5.5w = 227.5
We can use substitution or elimination here. Let's try substitution in this case:
c = 35 - w
7(35 - 7) + 5.5w = 227.5
245 - 7w + 5.5w = 227.5
245 - 1.5w = 227.5
-1.5w = -17.5
w = 11 2/3
Now to solve for cashews:
c = 35 - 11 2/3
c = 23 1/3
Check:
23 1/3 * 7 + 5.5 * 11 2/3 = 227.5
163 1/3 + 64 1/6 = 227.5
163 2/6 + 64 1/6 = 227.5
227 3/6 = 227.5
227.5 = 227.5

1. Find the equation of a line that is perpendicular to
y=-2/3+4 and goes through (0,5)
Answer:
Step-by-step explanation:
It says perpendicular, which means if you graphed the line given and the one you have to make, they would intersect at a right angle. I'm going to presume the x is after -2/3 since you didn't put one in, I hope that's correct.
The first part to solving problems like these is to invert the slope, which just means you have to switch the sign on it (negative to positive/positive to negative) and switch the numerator and denominator. This makes the new slope 3/2.
The next step is to find the y-intercept, which they thankfully gave you in this problem (when x=0 the y-value is always the y intercept), but you'll usually have to find it.
The equation is y=3/2x+5. You should double check this, I'm good at math but it's been a bit.

Answer:
3/4
Step-by-step explanation:
f(0) - f(3) / 0 - 3
f(0) = -4
f(3) = 9/4 - 16/4 = -7/4
f(0) - f(3) = [-4 - (-7/4)]
f(0) - f(3) = [-16/4 + 7/4]
f(0) - f(3) = -9/4
-9/4 ÷ -3 = -9/4 · -1/3 = 3/4
Section A has 80 marks Section B has 120 marks.
Riya scores
55% in Section A 70% in Section B.
To pass, Riya needs to score 65% of the total marks.
Does she pass? You must show your working.
Answer:
Riya does not pass
Step-by-step explanation:
From the question:
Section A has 80 marks
Section B has 120 marks.
The total marks from both sections = 200 marks
To pass, Riya needs to score 65% of the total marks.
Hence: 65% of 200 marks
= 65/100 × 200
= 130 marks.
To pass Riya must score 130 marks.
Riya scores:
For section A
55% in Section A
Her marks in section A = 55% × 80
= 55/100 × 80
= 44 marks
For section B
70% in Section B.
Her marks in section A = 70% × 120
= 70/100 × 120
= 84 marks
Therefore , the total marks Riya scored in both sections =
44 marks + 84 marks
= 128 marks
Riya scored a total of 128 marks. SHE DOES NOT PASS. Because the pass mark is a total of 130 marks from Section A and Section B

Factorise x² - x with explanation please?
Answer:
x(x + 1)
Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)
