What is an equation of the line that passes through the points (3,4) and (−4,−3)? Put your answer in fully reduced form
Answer:
The equation of the line is y = x + 1
Step-by-step explanation:
The equation of the line is y = m x + b, where
m is the slope of the lineb is the y-interceptThe rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ The line passes through points (3, 4) and (-4, -3)
∴ x1 = 3 and y1 = 4
∴ x2 = -4 and y = -3
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-3-4}{-4-3}[/tex] = [tex]\frac{-7}{-7}[/tex] = 1
∴ m = 1
→ Substitute it in the form of the equation above
∴ y = 1(x) + b
∴ y = x + b
→ To find b substitute x by 3 and y by 4 in the equation
∵ 4 = 3 + b
→ Subtract 3 from both sides
∵ 4 - 3 = 3 - 3 + b
∴ 1 = b
→ Substitute it in the equation
∴ y = x + 1
∴ The equation of the line is y = x + 1
Please help and give an explanation. I’m struggling
Answer:
y = 1/3x -4
Step-by-step explanation:
The y intercept is -4 as you can see in the graph. To find the slope look at the graph and find where it perfectly intercepts. It goes up one block and to the right three. So the slope is 1/3 . Since the line is going up to the top right it’s a positive slope.

What are the solutions of the equation X4-9x2 + 8 = 0? Use u substitution to solve.
O x = 1 and x = 2.13
O x=+1 and x=+22
O x= ti and X=
O x = ti and X=25
=+21/2
Answer: the answer is B
Step-by-step explanation:
The solutions of the equation X⁴-9x² + 8 = 0 is ±2√2 and ±1
How to solve equation using substitutionX⁴-9x² + 8 = 0
Let x² = y
Then the equation becomes y² - 9y + 8 = 0
This is in the form ax² + bx + c = 0
We can solve by using quadratic formula for finding roots
x = {-b ± √(b² - 4ac)} / 2a
where,
a = 1, b = -9, c = 8= {-(-9) ± √((-9)2 - 4(1)(8))} / 2(1)
= {9 ± √(81 - 32)} / 2
= {9 ± √49} / 2
= {9 ± 7}/2
= 16/2, 2/2
= 8, 1
y = 8,1
x = ±2√2, ±1

Jessica and her father are comparing their ages. At the current time, Jessica's father is 24 years older than her l. Three years from now, Jessica father will be five times her age at the point
Answer:
Jessica is currently 3 years old and her father is 27 years old.
Step-by-step explanation:
System of Equations
Let's call:
x = Jessica's age
y = Jessica's father's age.
There are two conditions:
1: Jessica's father is 24 years older than her or, equivalently:
y = x + 24
2: Three years from now, he will have five times her age.
Three years from now, Jessica will have x+3 years, and her father will have y+3 years, thus:
y + 3 = 5( x + 3 )
Substituting the first condition into the second:
x + 24 + 3 = 5( x + 3 )
Operating:
x + 27 = 5x + 15
Subtracting x and 15:
27 - 15 = 5x - x
12 = 4x
Solving:
x = 12 / 4 = 3
x = 3
y = 3 + 24 = 27
y = 27
Jessica is currently 3 years old and her father is 27 years old.

Basil, Oscar and Sue share 43 sweets.
Sue gets the largest share.
What is the smallest possible number of sweets Sue could get?
Answer:
Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.
Step-by-step explanation:
Basil, Oscar, and Sue share 43 sweets.
Sue gets the largest share.
Let us divide the 42 sweets by 3
42/3 = 14
It means 3 equal parts of 14 make the sum 4.
i.e. 14+14+14 = 42
Since Basil, Oscar and Sue share 43 sweets, which is 1 plus 42.
So, add that 1 to Sue. i.e. 1+14 = 15
so 15+14+14 = 43Thus, Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.
629 divided by the number c equals 17 what is c answer fast WILL MARK BRAINLY!!
Answer:
c=37
Step-by-step explanation:
The answer c is 37.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number
Here is is given that,
629 divided by the number c equals 17.
Here 629 is the dividend, c is the divisor and 17 is the quotient.
We have to find the value of the divisor.
Mathematically the given statement can be written as,
629 / c = 17
Multiplying both sides of the equation with c, we get,
629 = 17 c
Dividing both sides by 17,
c = 629 / 17
c = 37
Hence the value of c is 37.

Dina invests £450 in a savings account with annual compound interest.
After five years, there is £534.46 in the account.
What interest rate has she been receiving?
Answer:
3.3%
Step-by-step explanation:
compound interest: A = Pe^(rt)
A = 534.46
P = 450
t = 5
534.46/450 = e^(5r)
e^(5r) = 1.18
lne^(5r) = ln 1.18
(5r)lne = ln1.18
ln1.18 = 5r
5r = 0.165
r = 0.033
or 3.3%
What is angle A and B??
Answer:
A=45 b=110
Step-by-step explanation:
I used a calc
Answer:
A=135 b=200
Step-by-step explanation:
135+200+25=360
X+(x+65) +25=360
Subtract 25 from both sides
X+ (x+65)=335
Combine like terms
2x +65=335
Subtract 65 from both sides
2x =270
Divide by 2
X=135
To get b you just do 135+65=200
