Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
Answer:
-3.
Step-by-step explanation:
in the form y=mx+b, m is the slope
find the perimeter of a quarter circle with a radius of 7 inches.
Answer:
17.5in
Step-by-step explanation:
The circumference of a circle is pi multiplied by the diameter, so...
d=2r
d=14in x pi
Therefore the overall circumference is 14in x pi. A quarter of this would be the curved perimeter of the quarter circle.
14 pi/4=3.5in x pi
The quarter circle also includes 2 radii, and thus 7+7+3.5 is 14+3.5pi inches (pop it in your calculator as I don't currently have one at hand).
Answer:
The answer would be 43.98
Step-by-step explanation:
Multiple the Radius (7) by 2. You will get the circumference (14). Then multiply 14 by pi. 43.9822971503, or "43.98" just to be safe! ;-)

The temperature dropped overnight by 5.6° Fahrenheit every hour. What was the change in temperature after 4 hours?
a -1.4°F
b-1.6°F
C -9.6°F
d -22.4°F
For all real numbers a and b, 2a • b = a2 + b2 Is this true or false? Explain why it false or true.
Answer:
It's false.... correct is a2+2ab+b2
Step-by-step explanation:
This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9.
That's why it's false.

nina made 8 withdraws each were for $20. what was the total amount of change in her bank account.
The change in Nina'a account balance is -$160.
Nina made 8 withdrawals and each time she took $20.
The change in her account balance will therefore be whatever the account balance is less the amount that she withdrew.
The total amount of money she withdrew is:
= Number of withdrawals x Amount withdrawn each time
= 20 x 8
= $160
Her account is therefore lower by $160.
In conclusion, the change in her account balance is -$160.

A tree 24 feet tall casts a shadow 12 feet long. Brad is 6 feet tall. How long is Brad's shadow?
Answer:
Brad's shadow is 3 feet long
Step-by-step explanation:
If a tree is 24 feet tall, and casts a shadow 12 feet long, The we know the shadows will be half as big as the main object.
Because Brad is 6ft tall, His shadow will be half of his hight (3ft long)
The slope of the tree to shadow is equal to the slope of Brad to shadow. The Brad's shadow is 3 ft long.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
A tree 24 feet tall casts a shadow 12 feet long.
Brad is 6 feet tall.
The slope of the tree to shadow is equal to the slope of Brad to shadow (x). Then we have
[tex]\rm \dfrac{x}{6} = \dfrac{12}{24}\\\\x \ = \dfrac{6*12}{24}\\\\x \ = 3[/tex]

Carlos and Diya perform the same transformations on
the same pre-image, but in reverse order.
Carlos translates, then dilates. Diya dilates, then translates. Carlos claims the resulting images will always be the same. Diya disagrees. Who is right
Answer: Carlos is right
Step-by-step explanation:
why because in dilation, the image and the original are similar, in that they are the same shape but not necessarily the same size. They are not congruent because that requires them to be the same shape and the same size, which they are not (unless the scale factor happens to be 1.0).
Diya is wrong because the picture is the not the same size && the image is going to stay the same
