solve -12 = -8x + 60

Answer:

Step-by-step explanation:

L=2W-5 and P=2(L+W) is the system

Substituting L=2W-5 into P=2(L+W) gives you

2(2W-5+W)=P=60

2(3W-5)=60

3W-5=30

3W=35

W=35/3, L=2W-5

L=55/3

Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }

Step-by-step explanation:

Answer:

Step-by-step explanation:

There is no restriction upon x so the domain is all real numbers

x=(-oo, +oo)

y has a minimum value when x=12 and y=11. Any other value of x increases the value of y. So the range is all real numbers greater than or equal to 11.

y=[11, +oo)

Answer:

4) D) 20

3) A) 16°

Step-by-step explanation:

4)

You must follow the correct order of operations.

13 - 2(1 - 15)/4 =

Do the subtraction inside the parentheses first.

= 13 - 2(-14)/4

Now multiply -2 by -14.

= 13 + 28/4

Divide 28 by 4.

= 13 + 7

Finally, add.

= 20

Answer: D) 20

Answer:

B = (10, -4),  D = (58/9, -2)

Step-by-step explanation:

Point C(3.6, -0.4) divides in the ratio 3 : 2. If the coordinates of A are (-6, 5), the coordinates of point B are ___ . If point D divides in the ratio 4 : 5, the coordinates of point D are ___ .

Solution:

If point O(x, y) divides line segment AB with endpoints at A(x₁, y₁) and B(x₂, y₂) in the ratio n:m, then:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 ;\ y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Since point C divides AB in the ratio 3:2. Let the coordinates of B be (x₂, y₂). Hence:

[tex]3.6=\frac{3}{3+2}(x_2-(-6))-6\\\\9.6=\frac{3}{5}(x_2+6) \\\\x_2+6=16\\\\x_2=10\\\\\\-0.4=\frac{3}{3+2}(y_2-5)+5\\\\-5.4=\frac{3}{5}(y_2-5) \\\\y_2-5=-9\\\\y_2=-4[/tex]

B = (10, -4)

D divides CB in the ratio 4:5. Let D = (x, y). Hence:

[tex]x=\frac{4}{4+5}(10-3.6)+3.6 \\\\x=\frac{58}{9} \\\\\\y=\frac{4}{4+5}(-4-(-0.4))+(-0.4)\\\\y=-2[/tex]

Hence D = (58/9, -2)

Step-by-step explanation:

In 3 years Audra's account will be Deducted by $288.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In one month the amount deducted = $8.

In 3 years there are

= 12 x 3

= 36 months.

So, In 36 month the Deduction would be

= 36 x 8

= $288.

Answer:

wait what, what grade are u even in?? I barely understand this I'm in freaking 8th grade this is high school!

Answer:

0.527

Step-by-step explanation:

From the question,

The sequence is Geometry Progression (G.P)

Tₙ = arⁿ⁻¹.......................... Equation 1

Where n = number of term, a = first term, r = common ratio

Given: n = 7, a = 6, r = 2/3

Substitute these values into equation 1

T₇ = 6(2/3)⁷⁻¹

T₇ = 6(2/3)⁶

T₇ = 6(64/729)

T₇ = 384/729

T₇ = 0.527

Hence, the 7th term of the sequence is 0.527

Answer:

C

Step-by-step explanation:

C will have the least value with -99.

A would be 1/100, which is 0.01, which is small, but larger than -99.

B would be 10/100, which is 0.1, which is larger than A.

C is 1-100, which equals -99.

D is 10-100, which equals -90. -99 is smaller than -90.

Answer:

360 feet.

Step-by-step explanation:

If there are 2 end zones each measuring 10 yards long then that means that both together measure 20 yards long. We add this to the 100 yards of the field and we get a total length of 120 yards. Now we can simply turn this into feet, we know that ...

1 yard = 3 feet

120 yards = x feet

120 * 3 = x

360 feet = x

Finally, we can see that the length of the football field is 360 feet.

I can help you. What subject is it?

Step-by-step explanation:

Answer:

Step-by-step explanation:

If p varies jointly as m and r, then;

p = kmr

k is the proportionality constant

Given that p = 180, m = 5 and r = 8

180 = k(5)(8)

180 = 40k

k = 180/40

k = 4.5

To get m when p = 324 and r = 6

324 = 4.5(m)(6)

324 = 27m

m = 324/27

m = 12

Hence the value of m is 12
