Hi there!
[tex]\large\boxed{x = -1 \pm \sqrt{5}}[/tex]
We can solve by setting both equations equal to each other:
.5x + 4 = -.25x² + 5
Move everything to one side:
0 = -.25x² - .5x + 1
Multiply both sides by 4 to cancel out the decimals:
0 = -x² - 2x + 4
Factor out negative from both sides:
0 = x² + 2x - 4
Use the quadratic formula:
[tex]\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]
Plug in the corresponding terms:
[tex]x = \frac{-2 \pm \sqrt{4-4(-4)(1)}}{2}[/tex]
Simplify:
[tex]x = \frac{-2 \pm \sqrt{4 + 16}}{2}\\\\x = \frac{-2 \pm \sqrt{20}}{2}[/tex]
Simplify the radical to reduce:
[tex]x = \frac{-2 \pm 2\sqrt{5}}{2}[/tex]
Divide all terms by 2:
[tex]x = -1 \pm \sqrt{5}[/tex]

HELP DUE TUESDAY (last day of school)
please solve for x and y in the diagrams below:
x = 10°
y = 112°
Step-by-step explanation:
From the definition of supplementary angles,
68° + y = 180° ---> y = 180° - 68° = 112°
From the definition of vertical angles,
(4x - 2) + 30 = 68
4x - 2 = 68 - 30 = 38
4x = 40
x = 10
Answer:
y+68=180(being straight angle)
y=180-68
y=112
4x-2=30
4x=28
x=7

Find the missing value in the proportion 12/34 = 18/m.
Both the top and bottom numbers would have the same scale (ratio) in order to be a proportion.
Find the scale of the top numbers:
18/12 = 1.5
The top numbers have a scale of 1.5 so the bottom numbers also have a scale of 1.5
Multiply the known bottom number by the scale:
M = 34 x 1.5 = 51
Step-by-step explanation:
[tex] \frac{12}{34} = \frac{18}{m} \\ cross \: multiply \\ 12m = 612 \\ m = \frac{612}{12} \\ m = 51[/tex]

The formula to find the final velocity , v , of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
A.Rearrange the formula to find the acceleration
B. Using the formula in part A describe the relationship between the acceleration and time for a given initial and final velocity
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
[tex]a=\dfrac{v-u}{t}[/tex]
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
s is the distance covered
t is the time
Hence, this is the required solution.

The area of a rectangle is 70 square feet. The length is 10 feet. Find the width [W] of the rectangle
pls help
W = ___ ____
Answer:
35
Step-by-step explanation:
The answer might be 7 i don't know
Answer:
w = 7 feet
Step-by-step explanation:
The area of the rectangle, 70 ft², is equal to the length, 10 ft, times the width, w.
So, to find w, we can divide the area by the length.
w = 70 / 10
w = 7
The width is equal to 7 feet.
We can check this by multiplying the given length by the width that we've calculated to see if the area is equal to 70 feet².
10 · 7 = A
70 = A
Because the area we found is equal to the given area, our calculations are correct.
I hope this helps ^^

b)
Use a possibility diagram to find the probability that the product of the two resulting numbers is odd.
c)
What is the probability that the product of the two resulting numbers is at least 12
Answer:
2/15 ; 6/15 ; 1/5

Number on spinner = (2, 3, 5)
Number on card = (1, 1, 2, 3, 4)

1.)
To get a difference of 0:
{(2,2) ; (3,3)} = 2
Total possible outcomes = sample space = 15
P(difference of 0) = 2 / 15
2.)
Product of 2 resulting numbers is odd:
{(1,3) ; (1,5) ; (1,3) ; (1,5) ; (3,3) ; (3,5)} = 6
Total possible outcomes = 15
P(product is odd) = 6 /15
3.)
Product is atleast 12 :
{(3,5) ; (4,3) ; (4,5)} = 3
Total possible outcomes = 15
P(product is atleast 12) = 3/15 = 1/5

To find:
The end behaviors of the given function.
Solution:
We have,

The leading coefficient is -4 which is a negative value and the degree of the leading coefficient is 9 which is an odd number. So,
