Answer:
y=x-4
Step-by-step explanation:
Slope intercept form is y=mx+b (m=slope and b=y intercept)
so the equation would be y=1x-4 but you should simplify to y=x-4
Select the correct answer.
If the zeros of a quadratic function are 3 and 8, what are the factors of the function?
ΟΑ.
(X + 8) and (x - 3)
OB.
(x - 8) and (x + 3)
O C.
(X + 8) and (x + 3)
OD.
(x - 8) and (x-3)
Answer:
OD
Step-by-step explanation:
The zero x=8 will make the factor (x-8) = 0 and the zero x=3 will make the factor (x-3) = 0.
so it's (x-8) and (x-3)

Algebra I
Terms/Coefficients/DegreesStep-by-step explanation:
Step 1: Define
Set up equation.
mAB + mBC = mAC
x + 4 + 4 = 3x + 2
Step 2: Solve for x
Combine like terms: x + 8 = 3x + 2Isolate x terms: 8 = 2x + 2Isolate x term: 6 = 2xIsolate x: 3 = xRewrite: x = 3Step 3: Find AB
Define: mAB = x + 4Substitute in x: mAB = 3 + 4Add: mAB = 7Please help!! Why is sin(20) = sin(160) = -sin(200) = -sin(340)?
These relations all follow from the identity,
sin(x - y) = sin(x) cos(y) - cos(x) sin(y)
Notice that 160° = 180° - 20°, so if x = 180° and y = 20° above, we get
sin(160°) = sin(180°) cos(20°) - cos(180°) sin(20°)
We know sin(180°) = 0 and cos(180°) = -1, so we end up with
sin(160°) = sin(20°)
For the other, notice that 200° = 360° - 160°, and 340° = 360° - 20°.
Answer:
Step-by-step explanation:
sin 20 is the same as sin 60 because 180-60=20. sin 20 is the same as -sin200 because 200-180=20
sin 340 is the same as sin 20 because 360-340=20. So all four of these connect and they all equal 20. Also, they all equal .3420 (rounded)
write a linear equation to model the situation. you have walked 4 miles on a trail. you continue to walk at a rate of 3 miles per hour for h hours.
Answer:
[tex]y= 4 + 3h[/tex]
Step-by-step explanation:
Step one:
Given data
We are given that the initial distance walked is 4 miles
Also, the rate/ speed with which you are currently walking is 3 miles per hour
let the time taken be hours
and let the total distance be y
Step two:
We want to write an expression for the total distance
The total distance is given as
[tex]y= 4 + 3h[/tex]

answer pls : y- (-3y)
Answer:
4y
Step-by-step explanation:
When you subtract an already negative number then the two "minus signs" will become one addition sign and it just becomes y + 3y which is 4y
(Just for example: x- (-8x) would turn into x + 8x and the answer would be 9x)

Solve for the length of the hypotenuse
Answer:
5000
Step-by-step explanation:
In a right triangle ,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
where -
c = hypotenusea & b = the other two sides of the triangleAccording to the question , let the hypotenuse of the triangle be 'c' . So ,
[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]
[tex] = > c = \sqrt{9000000 + 16000000} [/tex]
[tex] = > c = \sqrt{25000000} = 5000[/tex]
Hence , c = 5000
Answer:
5000
Step-by-step explanation:
[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000
[tex]\sqrt{25000000}[/tex] = 5000

Answer:
5 forks2 spoonsStep-by-step explanation:
The higher-cost item is forks, so we can let x represent the number of those that are purchased. The total number purchased is 7, so the number of spoons purchased is (7-x).
The total cost is the sum of the costs for each of the items:
6x +5(7-x) = 40
x +35 = 40 . . . . . . simplify
x = 5 . . . . . . . . . . . subtract 35; the number of forks
7-x = 2 . . . . . . . . . the number of spoons
Daniel bought 5 forks and 2 spoons.
_____
Additional comment
Since $40 is not divisible by $6, we can guess that the number of forks Daniel bought will be a multiple of 5. That is, Daniel bought 0 or 5 forks. If he bought 0 forks, then he must have bought 40/5 = 8 spoons, so that is not a viable choice. The only number of forks that makes sense in this problem is 5 forks, so 2 spoons--numbers that total 7, as required.
Can someone help me with this please
Answer:
Step-by-step explanation:
4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling you... that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base .. along the b side will be the same.. so solving y is just the same as A or 52°
then to solve for x we also need to use that the triangle add up to 180° on those inside angles..
180= 52+52+14x+6
maybe you can solve it from here.. but i'll do it quickly
70 = 14x
5=x
5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x x= 34°
then use that the interior of the triangle add up to 180 again
180 = 34 + 5y+3 + 4y + 8
180 = 45 +9y
135 =9y
15 = y
