Answer:
f(0) = 2, x = - 2, x = - 1
Step-by-step explanation:
f(0) means what is the value of y when x = 0
x = 0 is a point on the y- axis
Thus when x = 0 , y = 2 , that is
f(0) = 2
(b)
The roots are the values of x on the x- axis where the graph crosses
This occurs at x = - 2 and x = - 1 ← roots

Answers
Answer:
x1=15, x2=10, angle A=45, angle B=135
Step-by-step explanation:
1st pic: since ray BD bisects angle ABC, 2x=x+15, subtract x from both sides to get x=15
2nd pic: using the same logic as above, x=4x-30. add 30 and subtract x from both sides to get 3x=30, divide by 3 to get x=10
since angle A and angle B are supplementary, A+B=180, since B=3A, we have A+3A=180, or 4A=180. divide to get A=45. since B=3A, B=3*45=135

solve for y -3.3+y/4=9.7
Answers
Answer: y= 5 /52 = 10 2/5 = 10.4
Step-by-step explanation:
-3.3+y/4=-9.7
We move all terms to the left:
-3.3+y/4-(-9.7)=0
We add all the numbers together, and all the variables
y/4+6.4=0
We multiply all the terms by the denominator
y+(6.4)*4=0
We add all the numbers together, and all the variables
y+25.6=0
We move all terms containing y to the left, all other terms to the right
y=-25.6

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.
Answers
To find the parallel :
First of all, Parallel equations should have the same slope and a different y-intercept!
Take the equation of a linear function : y = mx + b, the slope here is m and the y intercept is b.
When we’re given a point (x,y), we write our equation in the y = mx + b form, then substitute the given point for (x,y) and solve for B!
Practice
We already know our equation will be in the form y = mx + b
And we also know that the slope will be the same : m = 4/7
So y = 4/7x + b
Lets find b !
The line passes through the point (0,0) of origin :
0 = 4/7*0 + b
b = 0
So the y intercept is b = 0
And finally the equation will be :
y = 4/7x

The price of Stock A at 9 AM was $12.73. Since then, the price has been increasing at the rate of $0.06 per hour. At noon, the price of Stock B was 13.48. It begins to decrease at the rate of $0.14 per hour. If the stocks continue to increase and decrease at the same rates, in how many hours will the prices of the stocks be the same?
Answers
Answer:
Let the hours when they equalize=h, then we have:
12.25 + .13h=13 - .09h
.13h + .09h=13 - 12.25
.22h=.75 divide both sides by .22
h=.75/.22
h=3 9/22, hours, when they will equalize.
The stock prices will be the same in 3.4 hours.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
At 9 a.m., the price of Stock A was $12.73. Since then, the price has risen at a pace of $0.06 per hour. Stock B was trading at 13.48 at midday. It starts to fall at a pace of $0.14 each hour.
Let's assume the hours would be h when to equalize,
As per the given question, we can write the equation as:
12.25 + 0.13h = 13 - 0.09h
Rearrange the terms of h in the above equation,
0.13h + 0.09h = 13 - 12.25
Combine the likewise terms in the above equation,
0.22h = 0.75
Divide both sides by 0.22
h = 0.75/0.22
h = 3.4
Thus, the stock prices will be the same in 3.4 hours.

=========
0.5p + 0.75m <= 225
p = m + 50
-------------------
Substitute for "p" and solve for "m"::
0.5(m+50) + 0.75m <= 255
0.5m + 25 + 0.75m <= 255
2.25m <= 325
---
m <= 144.44
--------------------
# of oranges : 100 pound
# of pound of apples: m+50 = 250 pound

Answer:
Answer choice C should be more Resonable.
Step-by-step explanation: It is very obvious
because you are spending less than $225 and when it says at least 50 more it means that 50 is the bare minimum so the ideal choice is 150 more apples than oranges and likely the oranges will be 100 and aples will be 250 and you won't spend over $225.

x = 40 and y = 40
========================================================
Explanation:
The three angles involving x add up to 180 since they form a straight line or straight angle.
3x+0.5x+x = 180
4.5x = 180
x = 180/(4.5)
x = 40
Then note how the 0.5x and 0.5y angles are vertical angle pairs. Vertical angles form when we have two lines cross to form an X shape, and vertical angles are always opposite one another. Also, vertical angles are always the same measure.
0.5x = 0.5y
x = y
40 = y
y = 40
In the second step, I multiplied both sides by 2. Then I plugged in x = 40 we found earlier.

Answer:
56/100
Step-by-step explanation:
The decimal place has 2 digits which indicates two zeros. So the denominator will be 100. And 56 will become the numerator.
First set x equal to the decimal (we will solve for x):
x = 0.5666666666...
Now find 10x (we want to get the recurring digit right after the decimal point):
10x = 5.66666666666...
Next we can subtract x from 10x:
9x = 5.1
We can now get x by dividing both sides by 9:
x = 5.1/9
We can’t have a decimal in a fraction so we can multiply the top and bottom numbers by 10:
x = 51/90
