Answer:
x= -2
Step-by-step explanation:
First, write your equation with 8.5 substituted for y: 8.5= -3x +2.5
Next, subtract 2.5 from both sides to simplify the equation: 6= -3x
After that, divide both sides by -3 to get x by itself: -2 = x
So, when y=8.5, x=-2.

The zeros of a polynomial are 3/2 and 2/5. Find the polynomial.
___x²− ___x+6
Let the zeros of a polynomial be α and β.
Here,
α:- 3/2β:- 2/5Therefore to find the equation of polynomial we have to do sum of zeros of the polynomial and the product of zeros of the polynomial.
Sum of the zeros of polynomial are :-
[tex] \sf \alpha + \beta = \frac{3}{2} + \frac{2}{5} \\ \\ : \rightarrow \: \frac{15 + 4}{10} = \frac{19}{10} [/tex]
Product of the zeros of polynomial are:-
[tex] \sf \: \alpha \beta = \frac{3}{2} \times \frac{2}{5} \\ \\ : \rightarrow \cancel\frac{6}{10} = \frac{3}{5} [/tex]
We know,
p(x) = x² - (α +β)x + αβ
putting values we get
p(x) = x² - 19/10x + 3/5
Hence, This is the required polynomial.
Cars wheel are 28 inches in diameter. How far will the car travel if it’s wheels revolve 10,000 times without slipping?
Answer:
879,200
Step-by-step explanation:
to get the answer we first must get the circumference of the wheel then we must multiply it by 10,000. 28 times 3.14(pie) is equal to 87.92. 87.92 times 10,000 is 879,200.
Note: I rounded pie.

Answer:
x = 80°
Step-by-step explanation:
x + 36° + 76° + 74° + 94° = 360°
x + 280° = 360°
x = 360° - 280°
x = 80°

1. Donna bakes biscuits on a rectangle cookie sheet that is 30cm by 50cm. Each biscuit has a diameter of 8cm
A. What is the maximum number of biscuits Donna can bake at once on a cookie sheet?
B. If Donna bakes the maximum number of biscuits, what area do the biscuits take up on the cookie sheet?
Answer:
18
Step-by-step explanation:
we know that
[the area rectangular cookie sheet]=30*50--------> 1500 cm²
let's assume that each biscuit is inscribed in a square of 8 cm side
in the side of 30 cm can be placed -----> 30/8--------> 3.75-----> 3
in the side of 50 cm can be placed -----> 50/8--------> 6.25-----> 6
The maximum number of complete biscuits is 3*6------> 18 biscuits
the answer is 18 biscuit

An airplane left the airport in Nevada and traveled 3200.0 km to LA. The airplane had an average velocity of 222 m/s. How long was the flight from Nevada to LA in seconds. I will reward brainliest if right. Please and thank you.
Answer:
14,414.41 secondsStep-by-step explanation:
plane traveled 3200 km
aver. velocity = 222 m/s
find:
How long was the flight from Nevada to LA in seconds.
solution:
time = distance / velocity
= 3200 km x 1000 m
222 m/s 1 km
= 14,414.41 seconds
A triangle has sides with lengths of 11 inches, 18 inches, and 20 inches. Is it a right triangle?
yes IF
20² = 11² + 18²
20² = 400
and
11² + 18² = 121 + 324 = 445
so NOT a right triangle
A car has an initial velocity of 10 m/s and final velocity of 43 m/s. The time taken
to reach the final velocity was 3 seconds. What is the acceleration of the car?
Hint: Acceleration (in terms of velocity) = (final velocity - initial velocity)/(time) *
Answer:
160 m/s
Step-by-step explanation:
vi= 10m/s
a= 5om/s*2
t=3 second
vf=?
frist step: find s(distance)
s=vit+1/2 at*2=10m/s x3s +0.5 x50m/s*2 (3s)*2 =30m+225m=255m
second : find vf
s=(vf+vi)/2 xt
vf=2s/t- vi=2(255m)/3s -10 m/s=170 m/s-10m/s=160m/s
Therefore , the final velocity of the car is 160m/s
Solve (x 9)2 = 25. apply the square root property of equality: isolate the variable. startroot (x 9) squared endroot = plus or minus startroot 25 endroot if x 9 = 5, then x = . if x 9 = –5, then x = .
When a positive sign is considered then the value of x is -4 and when a negative sign is considered then the value of x is -14.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The equatiuon is (x + 9)² = 25.
Take square root on both sides, then we have
(x + 9) = ±5
For positive signs, we have
x + 9 = 5
x = -4
For negative signs, we have
x + 9 = -5
x = -14

What is the equation of the line that passes through the point -4, —8) and has a
slope of 4?
Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8

using this, you can make the following equation:
5x - 2 = 7x - 8
subtract 5x from both sides
-2 = 7x - 5x - 8
-2 = 2x - 8
add 8 to both sides
-2 + 8 = 2x
6 = 2x
divide both sides by 2

C. x>-2Step-by-step explanation:
The solution is to isolate the term x from one side of the equation.
-2x<4First, multiply by -1 from both sides.
(-2x)(-1)>(4)(-1)
Solve.
2x>-4
Then, divide by 2 from both sides.
2x/2>-4/2
Solve.
-4/2=-2
x>-2
Therefore, the correct answer is x>-2.
