Answer:
-3x^2 - 21x
Step-by-step explanation:
This question is representing multiplying two functions :
We are finding f(x) * g(x)
We know that f(x) is -3x and g(x) is x + 7, therefore :
(-3x)(x + 7)
Follow FOIL :
First :
(-3x)(x)
-3x^2
Outer :
(-3x)(7)
-21x
Therefore the answer is :
-3x^2 - 21x

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t. Which is an equivalent equation solved for a?
StartFraction f minus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.– v = a
StartFraction f plus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.+ v = a
Answer:
StartFraction f minus v Over t
EndFraction =a
Step-by-step explanation:
The equation for acceleration is a= f-v
-----
t
Rearrange f=v+at
solve for a
f= v+at minus v
-v -v
get a by itself. multiplication is happening a between and t so divide
f-v=at
--- ---
t t
a= f-v
----
t
Answer: The answer would be A

Find the equation of the line with slope = -7 and passing through (-7,51). write your equation in the form y=mx+b
Answer:
y = -7x + 2
Step-by-step explanation:
Since we do not have the y-intercept (or, when the x is 0) We will use the Slope Form Formula (y - y1 = m(x - x1)) to find the Slope Intercept Form Formula (y = mx + b)
Point: (-7,51)
Slope: -7
y - y1 = m(x - x1)
y - 51 = -7(x - (-7))
y - 51 = -7(x + 7)
y - 51 = -7x - 49
y = -7x - 49 + 51
y = -7x + 2

How is 7x20 similar to find ping 7x200?? GIVING BRAIN LIST TO BEST ANSWER
Answer:
the answer to both are multiples of 10
Step-by-step explanation:
Answer:
7x20 is similar to 7x200 because you are multiplying the same number with 20 and then 20x10. The answers will be similar in that they are the same first 2 numbers, but one answer will be 10 times bigger, or have one more 0. The answers would be 140 and 1400.

Step-by-step explanation:
cause u got to multiple
Answer:
around 29.7
Step-by-step explanation:
We can make a rectangle two tringles
Using a^2 + b^2 = c^2 we can find the diagonal
40^2 + 9^2 = c^2
800 + 81 = c^2
sqrt 881 is 29.6816442
we can round this to around 29.7

anyone know how to solve this?
Answer:
x = [tex]\sqrt{66}[/tex]
Step-by-step explanation:
This is using the altitude on hypotenuse theorem
(leg of big Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 6 × (6 + 5) = 6 × 11 = 66 ( take square root of both sides )
x = [tex]\sqrt{66}[/tex]
Answer:x = ≤∫⇄

Your parents have decided to install new carpeting in your room, which is rectangular and measures 10 feet by 12 feet. They want to spend at most $200 on the carpeting. At the flooring store, carpeting is sold by the square foot. How much money will your parents spend per square foot for carpeting?
Answer:
$1.67 per square foot
Step-by-step explanation:
First find the area of the carpet.
A=l times w
A-10(12)
A=120 square feet
Now divide 200 by 120
to find the price divide 200 by 120.
The total cost is rounded to $1.67 per square foot or round it to as many digits in your problem.
Terry has nuts and bolts the ratio of the number of nuts to the number of bolts is 7:9 if Terry has 36 bolts how many nuts does Terry have
Let the number of nuts and bolts be 7x and 9x respectively.
Number of bolts = 36[tex] \tt { \therefore{9x = 36}}[/tex]
Solving the formed equation :
[tex]: \implies \sf 9x = 36 \\ \\ [/tex]
By dividing both sides by 9 .[tex]: \implies \sf x = \cancel{\dfrac{36}{9} }[/tex]
By dividing 36 and 9 by 9.[tex]: \implies{\underline {\boxed{ \tt x = 4 }}}[/tex]
[tex]\huge {\therefore}[/tex] The number of number of nuts are 7x = 7*4 = 28.

A dinner costs $4.99. Joanie plans to tip the waitress 15%. How much is the tip? (TEKS
7.4D-R)
A $0.15
B $0.75
C $5.14
D $5.74
Answer:
The tip given to waitress is $0.75. Option B is correct.
Step-by-step explanation:
Cost of Dinner = $4.99
Tip to be given to waitress = 15%
We need to find the cost of tip.
The tip would actually be given 15% of the dinner cost i,e
Tip = 15% of 4.99
Solving to find tip cost
[tex]Tip = 15\% \ of \ 4.99\\Tip=15\% \times 4.99\\Tip=\frac{15}{100} \times 4.99\\Tip=0.75[/tex]
So, the tip given to waitress is $0.75. Option B is correct.

The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees?
Answer:
The smallest angle is 40.
Step-by-step explanation:
2x-6+3x+5+2x+20=180
7x+19=180
7x=180-19
7x=161
x=161/7
x=23
Now,
= 2x-6
= 2×23-6
= 40
= 3x+5
= 3×23+5
=74
=2x+20
=2×23+20
=66
