-3x + y= – 8
3x + 2y = – 13
X =?
y =?
Answers
Answer:
x=1/3
y=-7
Step-by-step explanation:
using the elimination method, you can add both equations vertically, to eliminate the x
-3x+y=-8
3x+2y=-13
3y=-21
y=-7
we then fix the value of y into the first equation
-3x+y=-8
-3x-7=-8
-3x=-8+7
-3x=-1
x=1/3

Your mother is 25 years older than you. Your father is 3 years older than your mother. The product of all three ages are 32,130. How old is your father?
Explanation would be appreciated!
Answers
If father is 3 years older than mother,
m +3 = f
The product of all three ages is 32130:
I-m.f = 32130
Substitute m with r+ 25:
m+3 =f r+ 25 + 3 = f r+ 28 = f
Substitute now f and m:
I- m.f = 32130 x(x+ 25)(x + 28) = 32130 (a2 + 25x)(x + 28) = 32130 3 + 28r2 + 25r + 700r = 32130 3 + 53r2 + 700r = 32130
Subtract 32130 from each side 3 + 53? + 700r – 32130 = 0
On the graph we can see that the only real solution is 17. > x = 17 m = 25 + 17 m = 42 f = m + 3 f = 42 + 3 f =|45
Our age is 17, Mother's age is 42 and father's age is 45.
Father’s age is 45
( sorry I know it’s too long but hope it helps )
My father is 42 years old as obtained from the cubic polynomial's real root.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
let my age be x years.
So, My mother is (x + 25) and my father is (x + 28) years.
∴ {x(x + 25)(x + 28) = 32130.
(x² + 25x)(x + 28) = 32130.
x³ + 53x² + 700x = 32130.
x³ + 53x² + 700x - 32130 = 0.
Now solving this has only one real solution x = 17.
So, My father is (17 + 25) = 42 years old.

which of the lines graphed has a slope of -2 and a y-intercept of 3
Answers
Answer:
I think b
Step-by-step explanation:
need a better quality photo
Answer:
B
Step-by-step explanation:
It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.

Help sir! Thank you, Mr Thompson
Answers
Problem 1
To find the y intercept, plug in x = 0 and simplify
f(x) = (x-2)(x+4)
f(0) = (0-2)(0+4)
f(0) = (-2)*(4)
f(0) = -8
We have x = 0 pair up with y = -8
The y intercept is (0,-8)
Answer: Choice D
========================================
Problem 2
(x-2)(x+4) is the same as x^2+2x-8 after using the FOIL rule. The distributive property is an alternate option.
The leading coefficient of x^2+2x-8 is 1. Since this leading coefficient is positive, it tells us that the parabola opens upward.
Answer: C) Parabola opens upward
========================================
Problem 3
Answers:
A = h(x)B = f(x)C = g(x)Explanation:
Note that 1-x^2 is the same as -x^2+1 and this has a negative leading coefficient. So the parabola opens downward. That must mean curve C matches with function g(x).
Both f(x) and h(x) have the same leading term of x^2. However, the constant terms are different. Because f(x) has a smaller constant (-4 is smaller than 4) this makes curve B to be f(x), while curve A is h(x). The larger the constant is, the further shifted up the curve will be.

Which statement correctly identifies the line of reflection?
A.The triangles are reflected across the X-axis
B.The triangles are reflected across the Y-axis
C.The triangles are reflected across the line Y=X
D.The triangles are reflected across the line Y=-X
Answers
Explanation: The line Y=X intersects through the origin and has a slope of positive 1, so if you imagine that line on the graph shown, you're able to see how the triangles are reflected across it.
Also, when the X and Y coordinates are "flipped" for each triangle, you can tell that it's reflected across Y=X. For example, the point at the right angle for the red triangle is (1,-1), while the corresponding point on the black triangle is at (-1,1), "flipping" the coordinates.
Hope this helps!!! :)
Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0
Answers
Answer:
a = 4 , b = -2
Step-by-step explanation:
3a + b = 10
2a + 4b = 0
(By using elimination method, eliminate one variable) - to get only one equation
(3a + b = 10 ) 4
2a + 4b = 0
12a + 4b = 40
(minus)
2a + 4b = 0
10a = 40
a = 40/10
a = 4
(substitute a into an equation to get b)
2a + 4b = 0
2(4) + 4b = 0
4b = 0 - 8
b = -8/4
b = -2
