a+(-7)+3=0
a=7-3
a= 4
Answer:
4
Step-by-step explanation:
There are two ways of going about this problem. One could simply substitute every given answer and simplify to see if it makes a true statement. Conversely, one could solve the given equation with inverse operations. In this case, it is easier to solve with inverse operations.
Undo parenthesis,
a + (-7) + 3 = 0
a - 7 + 3 = 0
Simplify,
a - 7 + 3 = 0
a - 4 = 0
Inverse operations,
a - 4 = 0
+4
a = 4

how to factor with the quadratic fourmula. n2-18n+66=0
If sec 50 = cosec 70, prove that 0 = 7.5°
Answer:
The proofing is given below:
Step-by-step explanation:
[tex]Sec 5\theta = cosec 7\theta\\\\cosec (90 - 5\theta) = cosec 7\theta\\\\Now\ on\ comparision \\\\90 - 5\theta = 7\theta\\\\90 = 7\theta + 5\theta\\\\90 = 12\theta\\\\\frac{90}{12} = \theta\\\\0.75 = \theta[/tex]
Hence, it is proved
3. The cost of the city permits needed to build this building is 150,000 no matter how many floors with
condos are built.
a. Create a function p(1) based on this information.
b. What is the slope of your function and what does it tell you?
Answer:
[tex]P(x) = 150000[/tex]
[tex]Slope = 0[/tex]
Step-by-step explanation:
Given
[tex]Cost = 150000[/tex]
Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:
[tex]P(x) = 150000[/tex]
Solving (b): The slope and its interpretation
A function is represented as:
[tex]f(x) = b + mx[/tex]
Where:
[tex]m=slope[/tex]
By comparing: [tex]f(x) = b + mx[/tex] to [tex]P(x) = 150000[/tex]
[tex]m = 0[/tex]
So:
[tex]Slope = 0[/tex]
What it means is that, no matter the number of floors, the cost remains unchanged.

A right square pyramid is shown. The base has a side length, b, of 30 centimeters (cm). The height, h, is 10 cm.
What is the length, in centimeters, of l?
Draw and label a triangle to model how to find the length of l.
What are the lengths of the legs? How do you know?
What is the length, in centimeters, of l? Use your model to help you find this value.
Answer:
Step-by-step explanation:
Without the illustration, I assume that L is the slant height of a triangular face.
L = √(15^2 + 10^2) = 5√13 cm
pls help me !! will mark brainliest... i just need you to solve for m<1 and m<7 !! thanks !!
Step-by-step explanation:
=( n-2)180
= ( 4 - 2 )180
= 360
So, 144 + 90 + m<2 +m<1 = 360
144 + 90 + 85 + m<1 = 360
319 + m<1 = 360
m<1 = 360 - 319
m<1 = 41
their is an unknown angle so let's call it x
let's find x first ( m<6=49)
x + m<6 = 180
x + 49 = 180
x = 180 - 49
x = 131
Now let's find m<7
m<7 + 38 + m<4 + x = 360
m<7 + 38 + 85 + 131 = 360
m<7 + 254 = 360
m<7 = 360 - 254
m< 7 = 106

Answer:
12.75ft²
Step-by-step explanation:
Step 1: Determine the formula for the area of a trapezoid
The formula for the area of a trapezoid is A=1/2(b1+b2)*h where b1 and b2 are the bases of the trapezoid and h is the height of the trapezoid.
Step 2: List given information
b1=8ft
b2=9ft
h=1.5ft
Step 3: Plug given variables into the formula
A=1/2(b1+b2)*h
A=1/2(8+9)*1.5
A=1/2(17)*1.5
A=8.5*1.5
A=12.75
So the area of the seat is 12.75ft²

Answer:
x = -1/2 or x = -3
Step-by-step explanation:
2x^2 + 7x + 3 = 0
First, we try factoring the polynomial.
(2x + 1)(x + 3) = 0
It works. Now we set each factor equal to zero.
2x + 1 = 0 or x + 3 = 0
2x = -1 or x = -3
x = -1/2 or x = -3

Which type of function is most likely to model these data?
A
linear function with positive rate of change
O
B
linear function with negative rate of change.
non-linear function that decreases then increases
D
non-linear function that increases then decreases
Answer:
D
Step-by-step explanation:
I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.
I can use problem-solving strategies to add and subtract fractions with unlike denominators.

Hey there!
If you do this, I would suggest saying "strongly agree"
This means that you can solve them using strategies that make it easier.
