Since the sum can be expressed as the ratio of two positive integers, it is rational.
if f(x)=-2x-3 what is f(r+2) ?
Answer:
[tex]f(x) = - 2x - 3[/tex]
when x is r + 2 :
[tex]f(r + 2) = - 2(r + 2) - 3 \\ = - 2r - 4 - 3 \\ = - 2r - 7 \\ \\ { \boxed{ \boxed{f(r + 2) = - 2r - 7}}}[/tex]

If a + b = 20 and ab = 75, find the value of a + b?
Answer:
a=5 or a=15, b=15 or b=5
Step-by-step explanation:
b=20-a
a(20-a)=75
20a-[tex]a^{2}[/tex] -75=0
-[tex]a^{2}[/tex]+20a-75=0
[tex]a^{2}[/tex]-20a+75=0
(a-5)(a-15)=0
a-5=0 or a-15=0
a=5 or a=15
b=15 or b=5
(:
Answer:
Step-by-step explanation:
a + b = 20
Sum of roots = 20
ab = 75
Product of roots = 75
x² - (a +b) x + ab = 0
x² - 20x + 75 = 0
Sum = coefficient of x = -20
Product = 75
Factors = 15 , 5 {15*5 = 75 & 15 +5 = 20}
x² - 15x - 5x + 75 = 0 {Rewrite the middle term}
x(x - 15) - 5(x - 15) = 0
(x - 15) (x - 5)=0
x - 15 = 0 ; x -5 = 0
x = 15 ; x = 5
a = 15 ; b= 5
If a = 1, b = 3, c = 4, what is x? Use the formula x= c/ (b-a).
Answer:
Step-by-step explanation:
A=1,B=3,C=4
X= 4/(3-1)
X= 4/2
X=2
Each big square below represents one whole What percent is represented by the shaded area?
Answer:
186%
Step-by-step explanation:
Looking at the squares, we can see that the first one has been completely shaded. That means that it is 100% shaded.
The second square has 86 out of 100 squares shaded, so that means that it is 86% filled.
Therefore 186% is filled by the shaded area.

22. Jesse's fish hook was 12 feet below the top of the water. He let out
some of his line, and the hook sunk another 3 feet. What is the depth of the
fish hook now? Write an addition problem, and then give the answer.
9514 1404 393
Answer:
15 ft below the top of the water
Step-by-step explanation:
We can let distances "below the top of the water" be represented by negative numbers. Then the initial height of Jesse's hook was -12 ft. Adding line allowed his hook to sink further:
-12 +(-3) = -15
The depth of Jesse's hook now is 15 feet below the water surface.

Identify the domain of the function shown in the graph.
Answer:
C. x is all real numbers.
Step-by-step explanation:
Since the domain is likely infinite, then the domain must be all real numbers so x is all real numbers.
Find the measure of unknown angle
Answer:
Step-by-step explanation:
z = 102 degree (opposite angles of a parallelogram are equal)
z + x + 34 = 180 degree 9sum of adjacent angles of a parallelogram is 180 degree)
102 + x + 34 = 180
x = 180 - 136
x = 44 degree
y + 102 + x = 180 degree (sum of interior angles of a triangle is 180 degree)
y + 102 + 44 = 180
y = 180 - 146
y = 34 degree
Answer:
x = 44°, y = 34°, z = 102°
Step-by-step explanation:
The opposite angles of a parallelogram are congruent , then
∠ z = 102°
Consecutive angles are supplementary , then
x + 34° + 102° = 180°
x + 136° = 180° ( subtract 136° from both sides )
x = 44°
∠ y = 34° ( alternate angle

SOMEONE PLEASE ANSWER!!!!
Evaluate each expression for t = 0, x = 1.5, y = 6, and z = 23
1. y + 5 = ??
2. z - 2x = ??
3. 2z - 2y = ??
4. 2.6y - 2x =??
5. 4(y - x) = ??
6. 4(2 + z) + 5 = ??
Answer:
1. 11
2. 20
3. 34
4. 12.6
5. 18
6. 105
Step-by-step explanation:
We are told that ---> t = 0, x = 1.5, y = 6, and z = 23
1. y + 5
= 6 + 5
= 11
2. z - 2x
= 23 - 2(1.5)
= 23 - 3
= 20
3. 2z - 2y
= 2(23) - 2(6)
= 46 - 12
= 34
4. 2.6y - 2x
= 2.6(6) - 2(1.5)
= 15.6 - 3
= 12.6
5. 4(y - x)
= 4(6 - 1.5)
= 24 - 6
= 18
6. 4(2 + z) + 5
= 4(2 + 23) + 5
= 8 + 92 + 5
= 105
