A line passes through the points (-4, 8) and (3, -7).
Answer all parts of the question.
Part A: What is the slope of the line that passes through these points.
Part B: What is the equation of the line that passes through these points.
Part C: Where does the line intersect the x-axis and y-axis?
Answer: (hope I got them correct)
A) -15/7
B) [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex]
C) It cuts the x-axis at (-4/15,0) and the y-axis at (0,-4/7).
Step-by-step explanation:
A) Slope = [8-(-7)]/(-4-3) = -15/7
B) Let [tex]y=-\frac{15}{7}x+c[/tex] be the required equation.
Substitute x=-4, y=8.
8=(-15/7)(-4)+c
c=-4/7
The equation is therefore [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex].
C) Substitute y=0, we will get x = -4/15 i.e. it cuts the x-axis at (-4/15,0).
Substitute x=0, we will get y = -4/7 i.e. it cuts the y-axis at (0,-4/7).

Calculate the value of x.
Answer:
x = 12
Step-by-step explanation:
[tex]90 + 3x + 16 + 2x + 14 = 180 [/tex]
[tex]5x + 120 = 180[/tex]
[tex]5x = 180 - 120[/tex]
[tex]5x = 60[/tex]
[tex]x = \frac{60}{5} = 12[/tex]
Answer:
x = 12°
Step-by-step explanation:
[tex](3x + 16) + 90 + (2x + 14) = 180 \\ 3x + 2x = 180 - 16 - 90 - 14 \\ 5x = 60 \\ x = \frac{60}{5} \\ x = 12[/tex]
Use the formula d = ( r − c ) t to find c if d = 30 , r = 12 , and t = 5 .

Which expression is a factor of 64x^2−25?
8x−5
32x−25
32x−5
8x−25
Answer:
A
Step-by-step explanation:
Answer:
[tex](8x-5)^{2}[/tex]
Step-by-step explanation:
Rewrite 64[tex]x^{2}[/tex] as [tex](8x)^{2}[/tex]
[tex](8x)^{2}[/tex]−80x+25
Rewrite 25 as 5^2.
(8x)^2−80x+5^2
Check that the middle term is two times the product of the numbers being squared in the first term and third term.
80x=2⋅(8x)⋅5
Rewrite the polynomial. [tex](8x)^2[/tex]−2⋅(8x)⋅5+[tex]5^{2}[/tex]
Factor using the perfect square trinomial rule [tex]a^{2}[/tex] −2ab + [tex]b^{2}[/tex]= [tex](a-b)^{2}[/tex], where a=8x and b=5.
[tex](8x-5)^{2}[/tex]
Find cos(a) in the triangle.
The value of Cosα from the triangle is 21/29
ABC is a right angled triangle
We have to find the Cosα
We know that cosine function is a ratio of adjacent side and hypotenuse
Let us find the value of Cosα
The adjacent side of angle α is 21
The hypotenuse is 29 in the triangle
Cosα = Adjacent side/hypotenuse
Plug in the values of adjacent side and hypotenuse
Twenty one divided by twenty nine
=21/29
Hence, the value of Cosα from the triangle is 21/29

Adam needs to build a shed and he can only use triangular frames that form a right
triangle for the corner walls. Which of the following dimensions for a triangular
frame should Adam use?
A 50 in., 110 in., 130 in.
B 25 in., 60 in., 65 in.
C 40 in., 44 in., 58 in.
D 130 in., 50 in, 60 in.
Answer:
Option B: 25 inches, 60 inches and 65 inches is the correct answer.
Step-by-step explanation:
We will use Pythagorean theorem to find out the dimensions that Adam should use.
A. 50 in, 110 in and 130 in
Using Pythagorean theorem;
[tex]a^2+b^2=c^2 \\(50)^2 + (110)^2 = (130)^2\\2500 + 12100 = 16900\\14600\neq 16900[/tex]
These dimensions will not form a right triangle.
B. 25 in, 60 in, and 65 in
[tex](25)^2 + (60)^2=(65)^2\\625+3600= 4225\\4225=4225[/tex]
These dimensions of the frame will form a right triangle.
C. 40 in., 44 in., 58 in.
[tex](40)^2+(44)^2=(58)^2\\1600+1936=3364\\3536\neq 3364[/tex]
These dimensions will not form a right angled triangle.
D. 130 in., 50 in, 60 in
The larger dimension represents the hypotenuse in right angled triangle.
[tex](50)^2+(60)^2=(130)^2\\2500+3600=16900\\6100\neq 16900[/tex]
These dimensions will not form a right angled triangle.
Hence,
Option B: 25 inches, 60 inches and 65 inches is the correct answer.

Hey there!
The correct graph is A
The slope, 2, is a positive slope, which means that the graph will go left to right going up, which rules out graph B.
The y-intercept is 1, which means it will intercept the y-axis at point (0, 1). That rules out graph C.
This means that graph A is correct.
Hope it helps and have a great day!

Answer:
Kate did 15/8 part more than that of John.
Step-by-step explanation:
Given that,
John did 3 3/4 of his homework while Kate did 1 7/8 of her homework.
We need to find how much more of their homework did Kate do than John. It can be calculated as follows :
3 3/4 = 15/4
and
1 7/8 = 15/8
So,
Difference,
[tex]d=\dfrac{15}{4}-\dfrac{15}{8}\\\\=\dfrac{15}{8}[/tex]
So, the required answer is 15/8.
If 176 dollars = 100 pounds and 1 pound = NRs. 119,
how much Nepali rupees can be exchanged with 132 dollar? find it
Answer:
NRs. 8925
Step-by-step explanation:
176 dollars = 100 pounds
132 dollars = ??? pounds
Using cross-multiplication, we get:
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Now, 1 pound = NRs. 119
So 75 pounds = NRs. ???
Using cross-multiplication again, we get:
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
So the answer is 8925 Nepali rupees
The Nepali rupees can be exchanged with 132 dollar should be considered as the NRs. 8925
Calculation of the amount:Since
176 dollars = 100 pounds
And, for 132 dollars = ??? pounds
So here we applied cross multiplication
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Also, 1 pound = NRs. 119
Now
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
