Answer:
what is this it looks so hard I don't have the answer
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
f(x) = 3x - 1
g(x) = x + 2
(f + g)(x) = f(x ) + g(x)
= 3x - 1 + x + 2
= 4x + 1
Standard fom: 4x20x² 24x

What is the value of y?
Answer:
y =24
Step-by-step explanation:
The exterior angle is the sum of the opposite interior angles
y+18 + 3y -41 = y+49
Combine like terms
4y -23 = y+49
Subtract y from each side
4y -y -23 = y+49-y
3y -23 = 49
Add 23 to each side
3y -23+23 = 49 +23
3y = 72
Divide by 3
3y/3 = 72/3
y =24
Which equation in point-slope form contains the point (4, –1) and has slope 3?
y + 1 = 3(x – 4)
y – 4 = 3(x + 1)
y – 1 = 3(x + 4)
y + 4 = 3(x – 1)
Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!
Hope this helps :)

A wildlife refuge has 200 birds when it is first established. It is so
successful that the number of birds increases by 25% every year.
Write a function to model the situation.
Find the number of birds present after 7 years.
Answer:
[tex](a)\ f(x) =200(1.25)^x[/tex]
(b) 954 birds after 7 years
Step-by-step explanation:
Given
[tex]a = 200[/tex] --- initial
[tex]r =25\%[/tex] --- rate
Solving (a): The function.
This is represented as:
[tex]f(x) =a(1+r)^x[/tex]
So, we have:
[tex]f(x) =200(1+25\%)^x[/tex]
Express percentage as decimal
[tex]f(x) =200(1+0.25)^x[/tex]
[tex]f(x) =200(1.25)^x[/tex]
Solving (b): Birds after 7 years
This implies that we calculate f(7)
[tex]f(7) =200(1.25)^7[/tex]
[tex]f(7) =953.67[/tex]
[tex]f(7) =954[/tex] --- approximated

A grocery store sells apple and oranges by the pound the cost of the apples is $1.30 the cost of the oranges is $1.84 how much more is the cost for 1 and 1 half pound of oranges than the cost for 1 and 1 half pounds of apples?
Answer:
1.5 pounds of oranges cost $0.81 more than 1.5 pounds of apples
Step-by-step explanation:
1.5 pounds of apples = 1.5 × $1.30 = $1.95
1.5 pounds oforanges = 1.5 × $1.84 = $2.76
$2.76 - $1.95 = $0.81

Answer:14 dollars, 2 pounds
Step-by-step explanation:
for they first one your just rounding wich is kinda easy you just round it up to the nearest dollar wich is 1 plus 13= 14 dollars.
for the second one it would be better to specify, but since we already did rounding on the first one this might be about the same topic, meaning it might be 2 pounds. But if not 2 and 1/4 of a pound.
Answer: the answer is in simple rounding-terms, 13.55 dollars rounded to dollars is just rounding off the cents, specifically the dimes or quarters. 55 cent can also be a half-dollar, but that is not important, 0.5 can be rounded to 1 in this case, so for question 14 you would add one to 13 dollars since 0.50 cents got rounded to 1 dollar and you get 14 dollars as your answer for the first question. for the next question American cheese i would assume is the same as the cheese referenced by Mr. Marsh, so the answer would be 2.25 pounds of cheese for number 15

. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Answer: [tex]3^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Monday was [tex]-5^{\circ}C[/tex]
By Tuesday, it becomes [tex]-2^{\circ}C[/tex]
Change in temperature is the difference between the two temperatures.
[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]
Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

Write and solve the equation to find the value of x and the missing angle measures.
Answer:
x = 8
The missing measures are 85 degrees
Step-by-step explanation:
Since 9x + 13 and 11x - 3 are on opposite sides, they are equal, so
9x + 13 = 11x - 3
Subtract 13 from both sides:
9x = 11x - 16
Subtract 11x from both sides:
-2x = -16
Divide both sides by -2:
x = 8
The angle measures are
9(8) + 13 = 72 + 13 = 85
11(8) - 3 = 88 - 3 = 85
Answer:
9x+13 = 11x-3
x = 8
The angles are 85
Step-by-step explanation:
The angles are vertical angles so they are equal
9x+13 = 11x-3
Subtract 9x from each side
9x+13 -9x = 11x-9x-3
13 = 2x-3
Add 3 to each side
13+3 = 2x-3+3
16 =2x
Divide by 2
16/2 = 2x/2
8 =x
11x-3 = 11(8) -3 = 88-3 = 85

the ratio of the ages of kapil and ramu is 4:5. After five years, the sum of their ages is 46 years. find the present ages
Answer:
Step-by-step explanation:
Let the age of Kapil is 4x and that of Ramu is 5x.
After 5 years,
Kapil's age = 4x+5
Ramu's age = 5x+5
ATQ,
4x+5+5x+5 = 46
9x+10 = 46
9x = 36
x = 4
Present age of Kapil = 4x = 4(4) = 16 years
Present age of Ramu = 5x = 5(4) = 20 years
What is the equation of the line?
Answer:
y = -7
Step-by-step explanation:
This is a horizontal line
The y value does not change
It is of the form y=
y = -7
Answer:
y = -7
Step-by-step explanation:
A horizontal line has an equation of the form
y = k
where k is the y-coordinate of every point on the line.
We see that every point on this line has y-coordinate -7, so the equation is
y = -7

Which ordered pair (x,y) is the solution to the given system of linear equation?
Answer:
(x, y) = (-1, 4)
Step-by-step explanation:
3x + 3y = -3 (1)
-2x + y = 2 (2)
From (2)
y = 2 + 2x
Substitute y = 2 + 2x into (1)
3x + 3y = -3 (1)
3x + 3(2 + 2x) = -3
3x + 6 + 6x = -3
9x + 6 = -3
9x = -3 - 6
9x = -9
x = -9/9
x = -1
Substitute x = -1 into (2)
-2x + y = 2 (2)
-2(-1) + y = 2
-2 + y = 2
y = 2 + 2
y = 4
(x, y) = (-1, 4)
Answer:
(-1,0)
Step-by-step explanation:

Problem 1
The two angles 6x and 30 are vertical angles, so they are congruent or the same in measure.
6x = 30
x = 30/6
x = 5 is the answer
====================================================
Problem 2
The two angles form a straight angle which is 180 degrees. We consider them a linear pair (since they are adjacent and supplementary).
So,
5x+(3x+12) = 180
8x+12 = 180
8x = 180-12
8x = 168
x = 168/8
x = 21 is the answer
