Answer:
[tex] {x}^{4} - {x}^{3} - {9x}^{2} - {11x}^{2} - 4 [/tex]
Step-by-step explanation:
Since the roots are -1,-1,-1 and 4 we can that as.
[tex](x + 1)(x + 1)(x + 1)(x - 4)[/tex]
x+1=0, x equal -1, and x-4=0 and x equal 4. Then apply the foil method to one at a time and you equal the answer above.

8x + 16y ≤ 4: does (2,9) work?
8(2) + 16(9) ≤ 4
16 + 144 ≤ 4
160 ≤ 4
160 is not smaller or equal to 4, so the point (2,9) does not satisfy the inequality.

If you were to teach a friend how to solve the following two-step equation : 3x + 18 = 48, what would you say, step by step? You may work it out first before you start your writing.
Answer:
Step-by-step explanation:
3x + 18 = 48
Bringing like terms on one side
3x = 48 - 18
3x = 30
x = 30/10
x = 3
Answer:
x = 10
Step-by-step explanation:
Subtract 18 from both sides.
3x=48-18
Simplify 48-18 to 30.
3x=30
Divide both sides by 3.
x= 30/3
Simplify 30/3\ to 10
x=10
x=10
Similar polygons have corresponding sides that are proportional and corresponding angles that are -
A congruent
B parallel
C similar
D proportional
What is the equation of the line that passes through the point ( -1, 1) and is perpendicular to 2x + 4y = 16?
A. y = −2x − 1
B. y − 3 = 2x
C. y = 6x + 7
D. Cannot be determined
Answer:
B
Step-by-step explanation:
We want the equation of the line that passes through the point (-1, 1) and is perpendicular to:
[tex]2x +4y=16[/tex]
Remember that the slopes of perpendicular lines are negative reciprocals of each other.
So, let's find the slope of the original line first. We can do so by converting it to slope-intercept form. Thus:
[tex]4y=-2x+16[/tex]
Therefore:
[tex]\displaystyle y=-\frac{1}{2}x+4[/tex]
The slope is -1/2.
The negative reciprocal of -1/2 is 2.
Thus, the slope of our new line is 2.
The slope is 2 and it passes through the point (-1, 1).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]y-(1)=2(x-(-1))[/tex]
Distribute:
[tex]y-1=2x+2[/tex]
Subtracting 2 from both sides yields:
[tex]y-3=2x[/tex]
Therefore, our answer is B.

It's not in a quadrant
The horizontal line (----) is the x-axis and the vertical line ( | ) is the y- axis
these split the graph into 4 parts, called quadrants.
They're usually labelled in roman numerals (I, II, III, IV)
Quadrant I is the top right
they're labelled counter-clockwise from there so
Quadrant II is the top left
Quadrant III is the bottom left and
Quadrant IV is the bottom right

Answer:
m<1=61
m<2=40
m<3=60
m<4=80
m<5=100
Step-by-step explanation:
180/3=60
180/9=20
20x2=40
20x4=80
20x3=60
59+60=119
180-119=61
180-80=100
What is the output of the function when the input is 10? On the graph plot this point and label its coordinates
Answer:
Output value = 20
Step-by-step explanation:
Graph of any function is made up of two values → Values on x axis and Values along y axis.
x values represent the input values and y values represents the output values.
For every x value there is a y value because of which the data set is called to a function.
In other words, a function can't have two output values for a single input value.
If the input value of function is = 10
Then for x = 10, out value (along y axis) will be = 20
Therefore, Output value of the given function is 20.

Solve w^2+13w+42=0 by factoring.
Answer: {-7, -6}
Explanation: When an equation has a squared term in it,
it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to 0, then factor.
Since this equation is already set equal to 0, we can factor the left side.
The left side is a trinomial that can be
factored as the product of two binomials.
The first term in each binomial will be a factor of the w².
Since w² factors a w · w, we use a w as our first term.
For the last terms, we use factors of 42 that add
to 13 and these factors are +7 and +6.
So we have (w + 7)(w + 6) = 0.
So either w + 7 = 0 or w + 6 = 0.
Solving for w in each equation, we find that our solution set is {-7, -6}.
pls tell me which to pick (a,b,c,or d)
Answer:
B (Y, N, N)
Step-by-step explanation:
a) y = 1/3x, so each value satisfies it. This is true.
b) If "a" is "Y" then b has to be no
c) 1 * 11 = 11
2 * 2 = 22
3 * 5 = 15
The last equation does not follow the rules for the previous two equations, so it is no.
Thus, the answer is B (Y, N, N)

WILL MARK BRAINLIEST WHOEVER ANSWERS THESE FIRST :DDD!!!
Answer:

2) x + 7 = 15 ; x = 15-7 = 8
3) 6x = 18 ; x = 18/6 = 3
4) x-4 = 11 ; x = 11 + 4 = 15
5) 1/7 x = 3 ; x = 3 *7 = 21
6) 13+x = 21 ; x = 21 - 13 = 8
I hope im right!!!

Step-by-step explanation:
As the figure can be split in to 3 geometric figure,
Rectangle , Triangle and Semi circle ,
So first find the area of these figures then add up them ,
Area of rectangle = Length * width
Length = 20m m and width = 14 mm
hence
Area of rectangle = 20*14 = 280 mm^2
Now ,
Are of Circle = [tex]\\ \pi *d^{2} /4[/tex]
Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]
Hence we have d= 20mm
Putt in semi circle formula we get,
Area of Semi Circle= (3.14)*400/8 = 157 mm^2
Now area of triangle = 1/2 * length*width
length =32-20 = 12 mm
width = 14 mm
putt in the formula we get ,
Area of triangle = 1/2*12*14 = 84 mm^2
Now add these 3 Areas to get total Area,
Total Area = 84+157+280 = 521 mm^2
