f(x) = –x^2 – 4x
Find f(-1)
Answer:
3
Step-by-step explanation:
Evaluate F(x) = –x^2 – 4x by substituting -1 for x:
F(-1) = –(-1)^2 – 4(-1)
This becomes:
F(x) = –1 + 4 = 3

Answer:
1.) 138
2.) 55
Step-by-step explanation:
1.) 8 x 6 = 48 x 2 = 96
(middle) 8 x 3 = 24
(triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18
96 + 24 + 18 = 138
2.) (middle) 5 x 5 = 25
(triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30
30 + 25 = 55

Answer:
Hey mate.....
Step-by-step explanation:
This is ur answer.....
Measure angle 2 = 125M.A 1 = 180 - 125 ( Supplementary angle)
M.A 1 = 55
M.A 3 = 125 (Vertically Opposite Angles)
M.A 4 = 55 (Vertically Opposite Angles)
M.A 5 = 55 ( Corresponding Angle)
M.A 6 = 125 ( Corresponding Angle)
M.A 7 = 125 ( Vertically Opposite Angle)
M.A 8 = 55 ( Vertically Opposite Angle)
Hope it helps!

Answer:
∠1 = 55°
∠3 = 125°
∠4 = 55°
∠5 = 55°
∠6 = 125°
∠7 = 125°
∠8 = 55°
Step-by-step explanation:
This is the detective case for vertical angles!!(dun-dun-dun!!!!)
Ok the info we have is that Angle 2 is 125°
Ok, quick, take ten seconds, the other group might take the victory coin. What is the vertical angle for angle 2?
-----
3! Correct
3 is the vertical angle because it is one part of the pair of opposite angles made by two intersecting lines.
3 is now 125°
The sum of all angles 1,2,3,4 is 360°
360° - 125° - 125° = 110°
110° / 2 (because 1 and 4 are vertical, they are equal) = 55°
1 = 55° and 4 = 55°
Lets do this for 5,6,7, and 8
Angle 1 = angle 5 because it is the law of same side interior(corresponding) angles, or they are the same because the lines are parallel to each other.
So angle 5= 55°
then angle 8 = 55°
6 = 125° and 7 = 125°
Yay you beat the other team. Great job you win a victory coin(which basically is something that is absolutely nothing)
simplify (2x+1)(x+8) - (x-3)(2x+1)
Answer:
22x+11 is your answer
Step-by-step explanation:
(2x+1)(x+8) - (x-3)(2x+1)
(2x+1)(x+8-x+3)
(2x+1)(11)
=22x+11
19.87 but there’s a 20% discount what’s the answer now?
19.87 = 100%
If you divide both sides by ten, you would get what ten percent is.
1.987 = 10%
Multiply this by two to get 20%.
3.974 = 20%
Minus twenty percent from the original amount.
18.87 minus 3.974 = 15.886 after the discount.

Step-by-step explanation:
find the length of side a
Answer:
a = 4
Step-by-step explanation:
a² = 5² - 3²
a² = 25 - 9 = 16
√16 = 4
a = 4
Answer:
a = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 3² = 5²
a² + 9 = 25 ( subtract 9 from both sides )
a² = 16 ( take the square root of both sides )
a = [tex]\sqrt{16}[/tex] = 4

I will greatly appreciate if you can solve this question!
Answer: The answer would be B
Write out the equation in slope-intercept form:
y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)
Subtract -5/3 from both sides of the equation:
y+5/3x=6
Subtract 6 from both sides:
y+5/3x-6=0
Multiply both sides by 3 to get rid of the fraction:
3y+5x-18=0
Then arrange the numbers to x and y are on one side by itself:
3y+5x=18
And that's your answer!
Hope this helped you!

An advertising flyer shows address labels as 4.3 cm by 1.2 cm. The ratio of the flyer label to the actual label is 2:3. What are the dimensions of the actual address labels?
Answer:
6.45 cm by 1.8 cm
Step-by-step explanation:
Ratio of label to actual measurement ; 2 : 3
For a flyer label size of 4.3
Actual label size equals :
(Flyer ratio / total ratio) * total size = flyer size
2/5 * x = 4.3
2x / 5 = 4.3
2x = 21.5
x = 21.5 / 2
x = 10.75
Actual size =. 10.75 - 4.3 = 6.45 cm
2/5 * x = 1.2
2x / 5 = 1.2
2x = 6
x = 6 / 2
x = 3
Actual size = 3 - 1.2 = 1.8 cm
6.45 cm by 1.8 cm
Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4 meter away from the launching point. If ava and mary are 5 meters apart, how high up is ava ?
Answer:
Ava's altitude is 3 meters.
Step-by-step explanation:
The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.
So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]
25 = 16 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 25 - 16
= 9
x = [tex]\sqrt{9}[/tex]
= 3
x = 3 meters
Thus, Ava's altitude is 3 meters.

[tex](10x + 9 {)}^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.
[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]
2) Use square sum: ( a + b )² = a² + 2ab + b².
[tex](10x + 9 {)}^{2} [/tex]
Hence, the answer is (10x + 9)².

Matti has one more pencil than Chang-Lin. Renaldo had three times as many as Chang-Lin, and one more than Jorge. Jorge has 5 pencils, how many pencils does Matti Have?
Answer:Matti has 3pencils
Step-by-step explanation:
Given that Jorge has 5pencils
Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils
But also
Renaldo =3Chang-Lin
6==3Chang-Lin
Chang-Lin = 6/3 =2
Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils
Eight burgers and three orders of fries cost $79.49. Six orders of fries and twelve burgers cost $125.82.Find the price of one burger and one order of fries .
Answer:
Burgers - $8.29 and fries - $4.39Step-by-step explanation:
Let burgers - b, fries - f
8b + 3f = 79.4912b + 6f = 125.82Double the first equation and subtract the second equation:
16b + 6f - 12b - 6f = 2(79.49) - 125.824b = 33.16b = 33.16/4b = 8.29Find f:
8(8.29) + 3f = 79.493f = 79.49 - 66.323f = 13.17f = 13.17/3f = 4.391. Anne had 1 hour for lunch.
