Answer:
The temperature changed by [tex]-12^\circ F[/tex] overnight.
The temperature changed by [tex]-1^\circ F[/tex] overnight each hour.
Step-by-step explanation:
Given that:
Temperature at 7 PM last night = [tex]10^\circ F[/tex]
Temperature at 7 AM the next morning = [tex]-2^\circ F[/tex]
a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM
[tex]\Rightarrow -2-10 =\bold{-12^\circ F}[/tex]
Negative sign indicates that the temperature has decreased.
b. Change in temperature each hour:
Divide the Change in temperature with the number of hours.
[tex]\Rightarrow \dfrac{-12}{12} = \bold{-1^\circ F}[/tex]
Negative sign indicates that the temperature has decreased.
Which of the following would have infinitely many solutions?
3x = 6 + 3x
2(x + 2) = 2x + 4 4x – 5 = 3 (x – 4)
-X + 6 = x + 6
9
Answer:
Below.
Step-by-step explanation:
2(x + 2) = 2x + 4
2x + 4 = 2x + 4
Both sides are identical so we can replace x with any value we like and the equation will balance, so there are infinitely many solutions.
Answer:
2(x+2)=2x+4

Answer:
D. 6 1/12
Step-by-step explanation:
First add the like fractions.
3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)
Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.
REMEMBER: You can only add and subtract fractions when they have the same denominator.3: 3, 6, 9, 12
4: 4, 8, 12
In this case 12 is the least common multiple.
3/4 x 3/3 = 9/12 9/12
4/3 x 4/4 = 16/12
Add those two fractions then add the whole numbers and put it in front.
4 25/12
Simplify
6 1/12

Answer:
5x^2 - 12x - 4 = 0
Step-by-step explanation:
5x - 3 (x - 2) = 10 + x
(5x - 3) (x - 2) = 10 + x
(5x^2 - 10x - 3x +6) = 10 + x
5x^2 - 13x + 6 = 10 + x
5x^2 - 13x +6 - 10 - x = 0
5x^2 - 12x - 4 = 0

Complete question:
Kyle incorrectly says that the product of - ( - 6 ) # ( - 1 ) is 6 . 11. After a recycling awareness program, the number of tons of recyclable material taken to the landfill is reduced by 13 7/10 tons per month. Represent the total change in the tons of recyclable material taken to the landfill after 7 months resulting from the awareness program a. What is the correct product? 10 month. Represent the total change in the b. What was Kyle's likely error?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Kyle incorrectly says that the product of - ( - 6 ) ( - 1 ) is 6
-(-6)(-1) = 6 [incorrect]
Correction:
-(-6) (-1) :
- (-6) = 6
6 (-1) = - 6
Given that reduction in materials = 13 7/10 tons per month
Monthly reduction = 13 7/10 = 137/10 tons
After 7 months : (7 * 137/10) = 959/10 tons = 95.9 tons
Change in amount of material taken to the land fill:
Initial amount - amount after 7 months
If initial amount = x
Change in amonnt = (x - 95.9) tons

A phone plan has a limit of $25 that can be spent on text messages. The base cost of the text plan will cost a user $5. Each text will cost $0.05. How many text messages (t) can a user send without exceeding the plan limits?
9514 1404 393
Answer:
400
Step-by-step explanation:
If the plan is used to its limit, the number of texts, t, that can be sent is ...
5 +0.05t = 25
0.05t = 20 . . . . . . . . . . subtract 5
t = 20/0.05 = 400 . . . divide by 0.05
A user can send 400 texts without exceeding plan limits.

Subtract 5x ^ 2 + 2x - 11 from 3x ^ 2 + 8x - 7 . Express the result as a trinomial.
Answer:
2x2−6x−4
Step-by-step explanation:
Let's simplify step-by-step.
5x^2+2x−11−(3x^2+8x−7)
Distribute the Negative Sign:
=5x^2+2x−11+−1(3x^2+8x−7)
=5x^2+2x+−11+−1(3x^2)+−1(8x)+(−1)(−7)
=5x^2+2x+−11+−3x^2+−8x+7
Combine Like Terms:
=5x^2+2x+−11+−3x^2+−8x+7
=(5x^2+−3x^2)+(2x+−8x)+(−11+7)
=2x^2+−6x+−4

write an equation of a line that passes through the point (4,2) with a slope of 1/4
Answer:
Slope Intercept Form: y = [tex]\frac{1}{4}[/tex] x + 1
Point Slope Form: y - 2 = [tex]\frac{1}{4}[/tex] × (x - 4)
Standard Form: 1x - 4y = -4
Step-by-step explanation:
Answer:
[tex]y=\frac{1}{4} x+1[/tex]
Step-by-step explanation:
A linear equation needs two pieces of information: the slope of the line, and its y-intercept. Since we are already given the slope we can plug that into the standard equation format:
y=mx+c, where m=slope and c=y-intercept
y=1/4x+c
Now we just need to find the y-intercept.
To find it we are given a point: (4,2), which we can use to trace back to the y-intercept using the slope. The slope of the line of 1/4. This means that the point before it is located 4 units to the left on the x intercept, and 1 unit lower on the y-intercept. Conveniently, this gives us our y-intercept, as the x values 4-4=0. The y value is 1 (2-1) so our y-intercept is 1!
So now we have our equation:
y=1/4x+1

3. Write the formula for the area of a triangle, A = 1/2 bh, in terms of h. Find
the height of a triangle when A = 18 in.? and b = 9 in.
Show work to get the answer
Answer:
Area = 1/2 bh
Area = 18
Base = 9
height = ?
18 = 1/2 x 9 x h
cross multiply
18 x 2 = 1 x 9 x h
36 = 9h
divide both sides by 9
h = 4
(a) The formula for area of a triangle is expressed in terms of h as [tex]h = \frac{2A}{b}[/tex]
(b) The height, h of the triangle is calculated as 4 in
Given:
area of a triangle, [tex]A= \frac{1}{2} bh[/tex]
To find:
the area in terms of hthe height, h, of the triangle when the Area, A = 18 in² and base, b = 9 in(a) The formula, (area of a triangle) is expressed in terms of h as;
[tex]A = \frac{1}{2} bh\\\\multiply \ both \ sides \ of \ the \ equation \ by\ 2\\\\bh = 2A\\\\divide \ through \ by \ b\\\\\frac{bh}{b} = \frac{2A}{b} \\\\h = \frac{2A}{b}[/tex]
(b) The height, h of the triangle is calculated as
[tex]h = \frac{2A}{b}\\\\Recall , A = 18 \ in^2 , \ b = 9\ in\\\\h = \frac{2\times 18}{9}\\\\h = 4 \ in[/tex]
