a. |5 - 7| =2
b. -3|11 - 15|=-12
Answer:
|5 - 7| =2
What you want to do first is to do the equation 5-7 which is -2 but there is an absolute value sign so 2.
-3|11 - 15|=-12
For this one it is a little more difficult but all you have to do is do the equation 11-15 which is -4 but there is an absoulte value sign so 4 you then multiply 4 by -3 which is -12 bam.

Answer:
-6x^2-1
Step-by-step explanation:
Find value
f(x)=-2x^2. g(x)=3x-1. Find g(f(x))
Solution:
f(x)=-2x2
g(x)=3x-1
g(f(x))=?
f(x)=-2x2,g(x)=3x-1,gof(x)=?
gof(x)=g(f(x))
Solution:
f(x)=-2x2
g(x)=3x-1
g(f(x))=?
f(x)=-2x2,g(x)=3x-1,gof(x)=?
gof(x)=g(f(x))
=g(-2x2)
=3⋅(-2x2)-1
=-6x2-1
gof(x)=-6x^2-1
Melvin borrowed $1,200 for furniture. His monthly payments were $60 for 24 months.
How much interest did Melvin pay on the loan?
$240
$1,200
$1,440
$2,880
Answer:
240.
Step-by-step explanation:
First you need to find out what his monthly payments are (60x24=1440)
Then you would subtract his monthly payments (1440) to the amount that he borrowed for the furniature (1200) which would give you 240.

Secant AD and AE intersect in the exterior of a circle. ∠ BAC measures 27.42° and the measure of DE is 73.18°. Determine the measure of BC .
Answer:
BC = 18.34°
Step-by-step explanation:
The secant- secant angle BAC is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( DE - BC) = 27.42
[tex]\frac{1}{2}[/tex] ( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )
73.18 - BC = 54.84 ( subtract 73.18 from both sides )
- BC = - 18.34° ( multiply both sides by - 1 )
BC = 18.34°
In 2004 kyle was 8 years old . In 2006 kyle was was four year older than his cousin albert. a.how old was albert in 2004. b. in what year was albert born
Answer:
Albert was born in the year 2000!
Step-by-step explanation:
2006 Kyle is 10
10 - 4 = 6
So, Albert was 6 years old in 2006
6 - 6 = 0
2006 - 6 = 2000
Kyle was born in the year 2000.
Answer:
A) 4 years old
B) 2000
Step-by-step explanation:
A) 2004 Kyle was 8 years old. Two years pass which makes Kyle 10. Kyle is 4 years older than his cousin 10-4 equal 6. Albert was 6 in 2006. 6-2 equal 4
B) Albert is 6 (2006) which means he was born in 2000.

Margaret has some cows. The cows produce an average total of 11.9
litres of milk per day for 290 days. Margaret sells the milk in 0.5 litre
bottles. Work out an estimate for the total number of bottles that
Margaret will be able to fill with the milk.
Answer:
6902
Step-by-step explanation:
Total milk produced in 290 days = 11.9 x 290 = 3451 litres
If 1 bottle has a capacity of 0.5l, the number of bottles needed = 3451 / 0.5 = 6902 bottles
The boss sent you to pick up lunch with $32.10, but you forgot how many hamburgers and hotdogs to pick up! The cost of a hamburger is $1.50 and the cost of a hot dog is $1.10. You must buy a combination of 23 items.
Answer:
Step-by-step explanation:
so we can make a system of equations
y=hotdogs
x=hamburgers
you need a combination that sums to 23, so add the two and get 23:
y+x=23
and then you need to account for how much money you have and the cost.
1.50x+1.10y=32.10

A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25, point, 25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.

if the edges of a cube are 6 inch edges. What is the volume?
Answer:
Volume = 216
Step-by-step explanation:
Answer:
216 in³
Step-by-step explanation:
volume of a cube = [tex]a^{3}[/tex]
a = 6
[tex]a^{3} = 6^{3}[/tex]

Answer:
y = 2x + 2
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(0, 2) & (6, 14)
Plug in these values:
(14 - 2) / (6 - 0)
Simplify the parentheses.
= (12) / (6)
Simplify the fraction.
12/6
= 2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = 2x + b
b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.
Therefore, our b-value is 2.
Plug this into our equation.
y = 2x + 2

Share 720cm in the ratio 3:4:2:9
Answer:
120 cm, 160 cm, 80 cm, 360 cm
Step-by-step explanation:
The ratio 3:4:2:9 is the same as the ratio 3x:4x:2x:9x
We add all the terms of the second ratio:
3x + 4x + 2x + 9x = 18x
18x = 720
x = 40
3x = 3(40) = 120
4x = 4(40) = 160
2x = 2(40) = 80
9x = 9(40) = 360
Answer: 120 cm, 160 cm, 80 cm, 360 cm
5x-2y=2 slope intercept form?
Answer:
[tex]y = \frac{5}{2}x-1[/tex]
Step-by-step explanation:
Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. So, to place the given equation in slope-intercept form, isolate the y on the left side and arrange the terms in that matching order. Remember, whatever you do to one side, do to the other:
[tex]5x-2y = 2\\-2y = -5x + 2\\\frac{-2}{-2}y = \frac{-5}{-2} x+\frac{2}{-2} \\y = \frac{5}{2} x-1[/tex]
So, the slope-intercept form is [tex]y = \frac{5}{2}x-1[/tex].

- A square flower bed has an area of 169/36 square yards. What is the perimeter of the flower bed?
Answer:
Step-by-step explanation:
Length of each side = √(169/36)
= √169/√36
= 13/6 yards
Perimeter = 4(13/6) = 26/3 yards
Perimeter of the flower bed is 26 / 3 yards
Given:
[tex]Area\ of\ square\ flower\ bed\ = \frac{169}{13} square\ yard\\\\[/tex]
Find:
Perimeter of the flower bed
Computation:
Area of square = side²
So,
[tex]Area\ of\ square\ flower\ bed\ = \frac{169}{13} square\ yard\\\\Side^2 = \frac{169}{36} \\\\Side^2 = [\frac{13}{6}]^2 \\\\Side = \frac{13}{6} \ yard[/tex]
Perimeter of square = 4(Side)
[tex]Perimeter\ of\ the\ flower\ bed = 4(\frac{13}{6} ) \\\\Perimeter\ of\ the\ flower\ bed = \frac{26}{3} \ yards[/tex]

Answer:
E. 1d+0.015d
G. 1.015d
Step-by-step explanation:
A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.
