The co-efficient value is "4 and 3".
Coefficient equation:[tex]\to 4x + 3y = 7[/tex]
Using the standard form to calculate value:
[tex]\to ax+bx+c=0[/tex]
compare the above value:
[tex]\to 4x + 3y -7=0\\\\\to ax + by +c=0\\\\[/tex]
co-efficient of x = 4
co-efficient of y = 3
constant term= -7
Therefore, the final answer is "4,3".

Which of the following is a solution to the system of two equations y = 3x – 7 and 4x – 5y = -20?
Answer:
x = 5, and y = 8
Step-by-step explanation:
You can solve this system by solving either of the equations for either x or y, and substituting that into the other.
Since the first equation is already defined for y, let's substitute that into the second equation:
4x - 5y = -20
4x - 5(3x - 7) = -20
4x - 15x + 35 = -20
4x - 15x = -20 - 35
-11x = -55
x = 5
We can then plug that into either of the original equations to find y:
y = 3x - 7
y = 3 * 5 - 7
y = 15 - 7
y = 8
We can also verify our answer by plugging one of the values into either of the original equations and seeing what we get:
4x - 5y = -20
4x - 5 * 8 = -20
4x - 40 = -20
4x = 20
x = 5
So we know the answer is correct. x is equal to five, and y is equal to eight.

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]
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]

Easy geometry question. Show only a little work.
Answer:
Where is question
Step-by-step explanation:
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.
