Answer:
c=1
Step-by-step explanation:
Simplify both sides of the equation first.
−8(1+4c)+7c=−25−8c
(−8)(1)+(−8)(4c)+7c=−25+−8c
−8+−32c+7c=−25+−8c
(−32c+7c)+(−8)=−8c−25
−25c+−8=−8c−25
−25c−8=−8c−25
Add 8 to both sides.
−17c−8+8=−25+8
−17c=−17
Divide both sides by -17.
-17c/-17 = -17/-17
c=1

2x+3y=12 complete the missing value in the solution to the equation ( 8,)
Answer:
Missing value is -4/3 and whole solution can be written as ( 8,-4/3)
Step-by-step explanation:
Given equation 2x+3y=12
solution ( 8,)
solution is form (x,y) hence in (8,) x is given as 8 while y is missing to find y
we will plug 8 as value of x in equation 2x+3y=12. From this equation we will find the missing value.
2x+3y=12
=> 2*8+3y=12
=> 16 + 3y = 12
=> 3y = 12-16= -4
=> y = -4/3
Thus, missing value is -4/3 and whole solution can be written as ( 8,-4/3)

Which is correct:
A) ƒ(x) = x2 – 7x + 20,000
B) ƒ(x) = 20,000 – 7x
C) ƒ(x) = 20,000(1.07)x
D) ƒ(x) = 20,000(0.93)x

If 2a+1/2a=10 find : 4a2+1/4a2
Answer:
98
Step-by-step explanation:
(2a + [tex]\frac{1}{2a}[/tex] )² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] , thus
10² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] ( subtract 2 from both sides )
100 - 2 = 4a² + [tex]\frac{1}{4a^2}[/tex] , that is
4a² + [tex]\frac{1}{4a^2}[/tex] = 98
Sara is having a dinner party for four friends and needs to reduce the serving size of the meatloaf recipe. She uses the equation StartFraction x over 4 EndFraction = 5. How many servings did the recipe originally make?
4
5
9
20
Answer: 20 servings
Step-by-step explanation:
From the question, Sara is having a dinner party for four friends and she needs to reduce the serving size of the meatloaf recipe. Sara used the equation x/4=5 . To get the number of servings the recipe originally made, we have to find the value of x.
x/4 = 5
x = 4 × 5
x = 20
This means that the recipe that was used originally made 20 servings.
Answer: D. 20 servings

3x-2y<-6
Write in slope intercept form
Answer:
y>1.5x+3
Step-by-step explanation:
All you need to do is isolate y, no coefficients, using basic algebra.
3x-2y<-6
-3x both sides
-2y<-3x-6
divide by -2 and switch the comparing sign to the other direction.
y>1.5x+3
Answer:
y > 3/2x +3
Step-by-step explanation:
3x-2y<-6
Subtract 3x from each side
3x-3x-2y<-3x-6
-2y< -3x-6
Divide each side by -2, remembering to flip the inequality
-2y/-2 > -3/-2x -6/-2
y > 3/2x +3

The expression 2(a+b)=−8.1 for certain values of a and b. Find the value of the following expressions for the same values of a and b: −0.5(a+b)
Answer:
Interpreting as: 2(a+b)=-8.1
Input:
2 (a + b) = -8.1
In Given the expression
2( a + b) = 8.1 ..........................(1)
now divide both sides of the first equation by 2 ,
2 (a + b) /2 = 8.1 /2
(a + b) = 4.05
expression -0.5(a + b) ................(2)
simply put the value of (a + b) in (2),
- 0. 5( 4.05) = -0.5 * 4.05
= 2.025
Value of expression is 2.025.

Nate is constructing a tangent line to a circle he drew from a point outside the circle. Once he has the circle and the point is drawn, what is his next step?
Answer:
The next step is to find the point on the circle which makes a tangent line that passes through the outside point.
Step-by-step explanation:
A tangent line to a circle is a line that touches the circle at exactly one point. You need two points to draw a line. You already have one point and the circle, then you need the other point, which lies on the circle. These two points have to lie on the same line. Notice that there are two possible tangent lines.
Answer:
connect the center of the circle to the point outside the circle

The surface area of a cube is 600 square inches. What is the area of one of its faces?
A.
6 square inches
B.
36 square inches
C.
75 square inches
D.
100 square inches
Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches
The expression w^4 – 36 is equivalent to..?
Answer:

=> w = √-6 and w = √6
The value of w is √-6 and √6 .
What is an identity?An identity is an equation that is true for all values of the variables.
For example:
The above equation is true for all possible values of x and y, so it is called an identity.
According to question one such identity will be used
[tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]
w⁴ - 36
= ( w² )² - ( 6 )²
= ( w² + 6 ) ( w² - 6 )
= w² + 6 = 0 and w² - 6 = 0
= w = √-6 and w = √6
Hence, w is a quadratic term so it have two value √-6 , √6 .

Find x in the given figure. answers : Question 7 options: 24 9 18 144
Answer:
x = 24.
Step-by-step explanation: given lines s and t are parallel and line m is a bisector, we can conclude that (2x+27) is an opposite exterior angle and congruent to the angle adjacent to (4x+9). Defining those 2 angles are supplementary, they = 180 degrees. Therefore, 2x+27+4x+9=180. Subtract 36 (27+9) from the left side of the equation as well as from the right side (180-36) you get 2x+4x=144. Add the x's you get 6x. So, 6x=144. Divide both sides by 6 and you get x=24.
