Answer:
f(7)= -48
Step-by-step explanation:
Evaluate f(x)= -3(9+x) for x=7.
Substitute 7 for x in f(x)=-3(9+x), obtaining f(7)= -48

#4. Identify the conclusion of the conditional statement: "I must reset the
clock if it's Daylight Saving time."*
A- I must reset the clock
B-It's Daylight Saving time
C-There is not conclusion
Answer:
C-There is not conclusion
Step-by-step explanation:
In a conditional statement, there is a hypothesis and a conclusion. It is usually symbolized or represented by " If X, then Y." It is an if - then statement.
Here, the statement "X" is called the hypothesis and the statement "Y" denotes the conclusion. The conclusion is true if the hypothesis is true.
The conclusion of any conditional statement is the immediate phrase that follows the word 'then'.
In the context, the sentence "I must reset the clock if it's Daylight Saving time." , the word 'then' is not there, so we can say that there is no conclusion in the statement.
Find the value of h(-67) for the function below. h(x) = -49x − 125
Answer:
h(-67) = 3158
Step-by-step explanation:
Simply plug in -67 for x:
h(-67) = -49(-67) - 125
h(-67) = 3283 - 125
h(-67) = 3158
Answer: h(-67) = 3158
Step-by-step explanation:
-49(-67)-125
3283-125
3158
what is the slope of the line below -3,2 3,2
a. negative
b.undefined
c. positive
d.zero
Answer:
0
Step-by-step explanation:
let (-3,2) be (x1,y1)
and(3,2)be(x2,y2)
Now,
slope = y2-y1/x2-x1
=2-2/3-(-3)
=0/3+3
=0/6
therefore slope=0

ej bisects def, m dej-5x+7, m JEF=8x-8. find x
Answer:
x = 5
Step-by-step explanation:
The information given has been sketched out in the attachment below.
Line segment EJ is an angle bisector of angle DEF. Therefore, m<DEJ = m<JEF.
The equation to find x would be expressed as follows:
5x + 7 = 8x - 8
Subtract 5x from each side (subtraction property of equality)
5x + 7 - 5x = 8x - 8 - 5x
5x - 5x + 7 = 8x - 5x - 8
0 + 7 = 3x - 8
7 = 3x - 8
Add 8 to both sides of the equation (addition property of equality)
7 + 8 = 3x - 8 + 8
15 = 3x
Divide both sides by 3
15/3 = 3x/3
5 = x
x = 5

Write y+1=-2x-3 in standard form
Answer:
y=2x-4
Step-by-step explanation: this looks alot like an equation for slope is it?
Answer:
-2x - y = 4
Step-by-step explanation:
Standard Form: Ax + By = k
Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:
y + 1 = -2x - 3
y (-y) + 1 = -2x - 3 (-y)
1 = -2x - 3 - y
1 = -2x - 3 - y
1 (+3) = -2x - 3 (+3) - y
4 = -2x - y
Set the equation so that it looks like the standard form equation given above:
-2x - y = 4 is your answer.

In circle V. r= 14ft.
What is the area of circle V?
14Tr ft2
28tt ft2
49tt ft2
196 ft2
Radius of circle = 14ft
We have to find the area of circle[tex].[/tex]
Area of circle of radius R is given by
A = π × R²⇒ A = π × R²
⇒ A = π × (14ft)²
⇒ A = 196π ft²

Find a · b.
a = −5, 1 / 2 ,
b = −5, 6
Answer:
a · b = 28 units
Step-by-step explanation:
Given vectors
a = (-5, 1/2)
b = (-5, 6)
The scalar or dot product of the two vectors, given by a · b is
a · b = (-5, 1/2) · (-5, 6)
To solve this, multiply the first term in a with the first term in b and add the result to the product of the second term in a and the second term in b. i.e
a · b = (-5 x -5) + (1/2 x 6)
a · b = 25 + 3
a · b = 28
Therefore, the dot product of a and b is
a · b = 28 units
