1st Question:
Our problem is [tex]-2x^2 - 10x + 100[/tex]
We have a common factor between the three terms, -2. So:
[tex]-2x^2 - 10x + 100[/tex]
[tex]-2(x^2 + 5x -50)[/tex]
We can factor further. What two numbers add up to 5 and multiply to -50? Our answer would be positive 10 and -5. Therefore:
[tex]-2(x^2 + 5x -50)[/tex]
[tex]-2(x +10)(x-5)[/tex]
2nd Question:
The problem is [tex]3x^3 + 9x^2 - 54x[/tex]
Like the first question, we can factor out a constant. In this case, we factor out a 3.
[tex]3x^3 + 9x^2 - 54x[/tex]
[tex]3(x^3 + 3x^2 - 18x)[/tex]
We can also factor out an x.
[tex]3(x^3 + 3x^2 - 18x)[/tex]
[tex]3x(x^2 + 3x - 18)[/tex]
We need to simply further. We can factor the quadratic into (x+6)(x-3).
[tex]3x(x^2 + 3x - 18)[/tex]
[tex]3x(x+6)(x-3)[/tex]
3rd Question:
Our problem is [tex]x^2 +12x + 20[/tex]
We do not have a coefficient, so we should factor the expression straight away. What two numbers add up to 12 and multiply to 20? the numbers 2 and 10. So:
[tex]x^2 +12x + 20[/tex]
[tex](x+2)(x+10)[/tex]
whats 34* 12 i have no idea I'm only 9
Multiply 1 & 2 from 3 and 4 respectively and add to get product.

T is proportional to c
Answer:
c ^ 2 * r ^ 2
Step-by-step explanation:
T is proportional to c * k * s^2
T is proportional to c * (k / r^2) * s^2
T is proportional to k * c ^ 2 * s ^ 2
T is proportional to infinity
The correct formula would be T is proportional to c ^ 2 * r ^ 2. This indicates that the temperature of the object is directly proportional to the inverse square of the distance from the center of the sun. This is because energy received decreases as the inverse square of the distance.

If vector u has its intial point at (-17,4) and it’s terminal point at (8,-11) u=
Answer:
[tex] - \frac{5}{3} [/tex]
Answer:
u = < 25, - 15 >
Step-by-step explanation:
To find u subtract the coordinates of the terminal point from the coordinates of the initial point.
u = < 8 - (- 17) , - 11 - 4 > = < 8 + 17, - 15 > = < 25, - 15 >
The sum of two numbers is twice their difference. The larger number is 5 more than twice the smaller. Find the numbers.
Answer:
18 and 6
Step-by-step explanation:
The sum of two numbers is twice their difference: 18 + 6 = 24, 18 - 6 = 12. 24 is twice of 12.
The larger number is 5 more than twice the smaller. Twice of 6 is 12. 5 more than 12 is 18.
Use matrices to write the equation of the function in the form y = mx + b that contains the points
(6.-29) and (-4,31). Record your values for slope, m, and y-intercept, b, below. Note: Your
answers should be integers.
The line has a slope of -6 and a y intercept of 7.
The linear equation is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y, x are variables.
The equation of the line passing through the points (6.-29) and (-4,31) is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-29)=\frac{31-(-29)}{-4-6}(x-6)\\\\y+29=-6(x-6)\\\\y=-6x+7[/tex]
Hence the line has a slope of -6 and a y intercept of 7.

What does f(5)=7 mean?
Step-by-step explanation:
Normally we write equation of functions like this: f(x) = x - 5
When we say f(5) = 7, we are implying that the x is 5.
The equation could look something like this: f(x) = x + 2
In this case, if you put x as 5, you will get 7 or 5 + 2
Means that 5 times of f equals to 7
Therefore f(5)-7=0Also f= 1.450 points and brainliest to first correct answer! :)
The figure below shows a quadrilateral ABCD. Sides AB and DC are congruent and parallel:
A quadrilateral ABCD is shown with the opposite sides AB and DC shown parallel and equal.
A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram:
Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent. Side AB is equal to side DC, and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by SSS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel.
Which statement best describes a flaw in the student's proof?
Question 11 options:
Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.
Triangles ABD and CDB are congruent by the SAS postulate instead of the SSS postulate.
Triangles ABD and BCD are congruent by the AAS postulate instead of the SSS postulate.
Angle DBC and angle BDA form a pair of corresponding angles, not a pair of alternate interior angles, which are congruent.
Answer/Step-by-step explanation:
"Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle CDB, are congruent." True
"Side AB is equal to side DC and DB is the side common to triangles ABD and BCD." True
Now we have 2 triangles, with 2 congruent sides, and the angles between these pairs of congruent sides, are also congruent..
This means that:
Therefore, the triangles ABD and CDB are congruent by SAS postulate, NOT SSS postulate, which would require 3 pairs of congruent sides.
Answer: Triangles ABD and CDB are congruent by the SAS postulate.

What is the vertex of the parabola ?
Answer:
(2,-9)
Step-by-step explanation:
Multiply out the polynomial to get:
x^2-4x-5
the vertex formula is -b/2a (use the coefficients of the equation above)
-(-4)/2(1) = 4/2 = 2
we know the x value of the vertex is 2. Now we can plug that into the original equation to get the y value.
(2-5)(2+1)
(-3)(3) = -9
so the coordinate is (2,-9)

(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
