Find the sum or difference. 1 1 34 1-5 a. -122 + 42 b. -0.35 - (-0.25)
Answer:
11341-5=11336
-122+42=-80, when you have different signs always keep in mind that you have to subtract and then get the sign of the big number.
for the third one you firstly have to work with the two negative signs,you have to multiply them, take note that when you multiply a negative by a negative you get a positive, a positive by a positive you get a positive and a negative by a positive you get a negative.
-0.35-(-0.25)
-0.35+0.25
=-0.1

worth 10pts!!! Can someone help?
Answer:
-4
Step-by-step explanation:
The average rate of change of the interval [a,b] is (f(b)−f(a)) / (b−a)
Replacing a=−5, b=4, f(x)=−x^2−5x+12.
(f(b)−f(a))/(b−a) =12−5x4− 4^2 − (12−5 x(−5)−(−5)^2)/ (4−(−5))= −4.

Use the drop-down menus to label the graph according to its type. On a coordinate plane, a graph has two straight lines that connect at (0, 0). One line has a positive slope from (0, 0) going through (3, 2) and the other has a negative slope from (0,0) going through (4, negative 3). The graph above:
The point of intersection of the graph of y = (2/3)x and y = (-3/4)x is at point (0, 0).
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The straight line passing through (0, 0) and (3, 2) have an equation of y = (2/3)x while the straight line passing through (0, 0) and (4, -3) have an equation of y = (-3/4)x

How to do these two questions?
Answer:
C
A
Step-by-step explanation:
adjacent means neighboring, right next to it. that would be 1 and 4.
supplementary means being a complementary, an additional angle, so that in sum both angles together have 180 degrees. and that is only 1.
so, C is the answer.
angle 7 = 115 degrees.
so, angle 8 is supplementary to angle 7.
they are being mirrored on the other side of the line.
so, angle 6 = angle 7, and angle 5 = angle 8.
and the same quadruple of angles have to appear, where the crossing line crosses another, parallel line. they have to be the same angles there again.
so, angle 3 = angle 7, angle 4 = angle 8, angle 1 = angle 5, angle 2 = angle 6.
and because angle 6 is also = angle 7, we have angle 2 = angle 7 = 115 degrees.
Answer:
C and A
Step-by-step explanation:
∠ 5 and ∠ 1 are adjacent ( next to each other) on the same line
The angles on a straight line sum to 180° ( supplementary )
Then ∠ 1 is adjacent and supplementary to ∠ 5 → C
----------------------------------------------------------------------------
∠ 2 and ∠ 7 are alternate exterior angles and are congruent , then
∠ 2 = ∠ 7 = 115° → A

Luis reads the temperature of a solution in a lab experiment. The temperature of the solution is 5.6º F. After 6 hours, he reads the temperature of the solution again. The temperature of the solution is now −1.2°F .
Luis plots the points on the number line to determine the temperature change between these two readings.
What is the temperature change?
ANSWER:____° F
The temperature change after 6 hours is 6.8°F
Initial temperature = 5.6°F
Initial temperature = 5.6°FFinal temperature after 6 hours = -1.2°F
The temperature change can be calculated as the difference in the value of final and initial temperature.
Temperature change = (final temperature - initial temperature)
Temperature change = (5.6 - (-1.2))°F
Temperature change = (5.6 + 1.2)°F = 6.8°F
Hence, temperature change after 6 hours is 6.8°F

Once upon a time there was a farmer whose family raised pigs and chickens. If you counted 24 heads and 80 feet, how many chickens were there? How many pigs were there?
Answer:
Number of chickens = 8
Number of pigs = 16
Step-by-step explanation:
Let the pigs = p
Let the number of chickens = c
Number of heads = 24
p + c = 24 ----------------(I)
p= 24 - c
Number of feet = 80
Chicken has 2 legs and pig has 4 legs
4p + 2c = 80 --------------(II)
Substitute p = 24 - c in equation (II)
4*(24 - c) + 2c = 80
4*24 - 4*c + 2c = 80
96 - 4c + 2c = 80 {Combine like terms}
96 - 2c = 80 {subtract 96 from both sides}
-2c = 80 - 96
-2c = -16 {Divide both sides by (-2)}
c = -16/-2
c = 8
Plugin c = 8 in equation (I)
p + 8 = 24
p = 24 - 8
p = 16
Two angles are complementary. One angle's measure is 3 more than 9
times the other angle. What is the measure of each angle? Write each
angle's measure separately.
Answer:
The measure of one angle is 81.3° and the other angle is 8.7°.
Step-by-step explanation:
We are given that two angles are complementary. One angle's measure is 3 more than 9 times the other angle.
Let the measure of one angle be 'x' and the measure of other angle be 'y'.
So, according to the question;
The first condition states that two angles are complementary, this means that the sum of both angles must be equal to 90°, i.e;x + y = 90°
x = 90° - y ---------------- [equation 1]
The second condition states that One angle's measure is 3 more than 9 times the other angle, i.e;x = 3 + 9y ------------ [equation 2]
Now, both the equations we get;
90 - y = 3 + 9y
9y + y = 90 - 3
10y = 87
[tex]y=\frac{87}{10}[/tex] = 8.7°
Now, putting the value of y in equation 1 we get;
x = 90° - y
x = 90° - 8.7° = 81.3°
Hence, the measure of one angle is 81.3° and the other angle is 8.7°.

Answer: $0.06 per inch
Concept:
When encountering questions that ask for unit price, follow the statements to get the answer. For example, this question asks the price per inch. Therefore, in the actual answer, use the total price given divided by the number of inches.
Solve:
Price = $6.48
Inch = 9 × 12 = 108 in
1 ft = 12 inchPrice / Inch = 6.48 / 108 = $0.06 per inch

The sum of two numbers is 50. If the larger number is divided by the
smaller number we get 7/11. Find the numbers.
Answer:
Set two equations:
Number #1 = xNumber #2 = y[tex]\left \{ {{x+y=50} \atop {\frac{x}{y}=\frac{7}{11} }} \right.[/tex]
Rearrange one of the equations to find the value of a variable:
[tex]x+y=50\\x=50-y[/tex]
Substitute in that value into the other equation:
[tex]\frac{50-y}{y}=\frac{7}{11}[/tex]
Cross-multiply & solve for y:
[tex]7y=11(50-y) \\7y=550-11y\\7y+11y=550\\18y=550\\y=\frac{550}{18}=\frac{275}{9}[/tex]
Substitute in the value to the original equation to find x:
[tex]\frac{x}{\frac{275}{9}}=\frac{7}{11} \\\frac{9x}{275}=\frac{7}{11} \\9(11)x=275(7)\\99x=1925\\x=\frac{1925}{99} =\frac{175}{9}[/tex]
Therefore, the answer will be:
x = [tex]\frac{175}{9}[/tex]y = [tex]\frac{275}{9}[/tex]You can check your answers by:
[tex]\frac{175}{9} +\frac{275}{9} =\frac{450}{9} =50[/tex]
[tex]\frac{\frac{175}{9} }{\frac{275}{9} } =\frac{175}{9} *\frac{9}{275} =\frac{175}{275}=\frac{7}{11}[/tex]
Answer:
x = 175/9
y = 275/9
Step-by-step explanation:
Let the larger number be 'x' and smaller number be 'y'
sum of two numbers is 50.
x +y = 50 --------(I)
x = 50 - y -------------(II)
The larger number is divided by the smaller number we get 7/11.
[tex]\frac{x}{y}=\frac{7}{11}\\\\[/tex]
Cross multiply,
11x = 7y
11x - 7y = 0 ------------(III)
Substitute x = 50 -y in equation (III)
11*(50-y) - 7y = 0
11*50 - 11*y - 7y = 0 {Distributive property}
550 - 11y - 7y = 0
550 - 18 y = 0 {Combine like terms}
Subtract 550 from both sides
- 18y = -550
Divide both sides by (-18)
y = -550/-18
y = 275/9
substitute y = 275/9 in equation (III)
[tex]11x - 7*(\frac{275}{9})=0\\\\11x-\frac{1925}{9}=0\\\\11x =\frac{1925}{9}\\\\x=\frac{1925}{9*11}\\\\x=\frac{175}{9}[/tex]

Since this is a right triangle and we are given the two legs, we can use the Pythagorean Theorem.
The Pythagorean Theorem is:
[tex]c^2=a^2+b^2[/tex]
Where c is the hypotenuse (longest side) and a and b are the two legs.
Plug in 10 and 14 for a and b (it doesn't matter which one) and solve for c.
[tex]c^2=10^+14^2\\c^2=100+196\\c^2=296\\c=\sqrt{296}=\sqrt{4\cdot 74}=\sqrt4\cdot\sqrt{74}=2\sqrt{74}[/tex]
