Which expression has a value of -8?
A 14 + 2(−5) − (3)(9)
B (10 ÷ 5) − (2 ∙ 4) − 5 + 8
C −4 − 5 − 1 − 2(4) + 10
D 12 − 2(4) + (5 − 2) − 33
Factor the expression: 12xy+15xyz-3xyz
Answer: 12xy + 12xyz
Step-by-step explanation:
15xyz - 3xyz = 12xyz + 12xy
On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday to Thursday. What is the temperature on Thursday?
Answer: [tex]-8^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Tuesday is [tex]1^{\circ}C[/tex]
Temperature drops to [tex]-2^{\circ}C[/tex] on Wednesday
Net drop in temperature [tex]1-(-2)=3^{\circ}C[/tex]
The temperature drops twice from Wednesday to Thursday
[tex]\Delta T=2\times 3=6^{\circ}C[/tex]
Temperature on Thursday
[tex]\Rightarrow -2-6=-8^{\circ}C[/tex]

Write the formula to evaluate the rate of VAT (V%) if
selling price with VAT is Rs. x and selling price without
VAT is Rs. y.
help.
Answer:
V% = (100(x - y)/x)%
Step-by-step explanation:
We are given;
Selling price with VAT = Rs. x
Selling price without VAT = Rs. y.
Thus; VAT = Rs. (x - y)
Rate of VAT(V%) = ((x - y)/x) × 100%
= (100(x - y)/x)%

Find the measure of angle H
Answer:
80
Step-by-step explanation:
All triangle angles add up to 180 so:
4x - 20 + 2x + 2x = 180
8x - 20 = 180
8x = 200
x = 25
<H:
4x - 20
4(25) - 20
100 - 20

determine equation for line that is perpendicular to x=-2 and passes through the point (6,1)
Answer:
y = 1
Step-by-step explanation:
1. A line has a slope of 6 and includes the
points (-1, q) and (0, -7). What is the
value of q?
Answer:
q = - 13
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 6
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, q) and (x₂, y₂ ) = (0, - 7)
m = [tex]\frac{-7-q}{0+1}[/tex] = - 7 - q , then
- 7 - q = 6 ( add 7 to both sides )
- q = 13 ( multiply both sides by - 1 )
q = - 13
Answer:
q = -13?
Step-by-step explanation:
the equation is y = mx + c
m is the gradient
c is the y-intercept
where the line crosses the y axis
If 6 is the gradient then the equation is
y = 6x + c
Find c by using the coordinates given:
-7 = ( 6× 0) +c
-7 = 0 + c
c = -7
the equation is y = 6x -7
Substitute the other coordinates to find q:
y or q = (6 ×-1) - 7
q = -6 -7
q = -13
Sierra has plotted two vertices of a rectangle at (3,2) and (8,2). What is the length of the sides of the rectangle
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units
Use the distributive property to expand (simplify) 12(a-5)
Answer:
12a-60
Step-by-step explanation:
12(a-5)
=12a-12*5
Multiply 12 *5=60
=12a-60
Answered by NONE other than the ONE & ONLY #QUEEN herself aka #DRIPPQUEENMO!!!
HOPE THIS HELPED!!!
Answer:
[tex]\huge\boxed{\boxed{12a-60}}[/tex]
Step-by-step explanation:
Hello.
The Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be either constants or variables
we distribute a by multiplying it times b and c, and simplify if necessary.
In this case, we should distribute 12:
12(a-5)
12 times a and 12 times (-5):
12a-60
And we're done!
I hope it helps & have an outstanding day!

4. What is the half-life of the radioactive isotope with amount A, whose rate of decay in t hours is shown in the graph below?
(0,40)
(20,15)
Answer:
15, 25
Step-by-step explanation:
Answer:The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. The answer is C.

The larger triangle is a dilation of the smaller triangle with a center of dilation at (1,−1)
What is the scale factor of the dilation? No Links and brainlest
18
14
4
8
Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor = [tex]\frac{\text{Dimension of the larger (Image) triangle}}{\text{Dimension of the smaller (Preimage) triangle}}[/tex]
From the given triangle,
Length of one side of the larger triangle = 8 units
Length of the corresponding side of the smaller triangle = 2 units
By substituting the values in the formula of scale factor,
Scale factor = [tex]\frac{8}{2}[/tex]
Scale factor = 4

Question: Based on the data set above for the hours per day sixth graders spend using an electronic device, what is the mean number of hours sixth graders use an electronic device?
No links, useless words, or anything like that. I will report you.
Answer:
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
1+1+1+1+2+3=9
2+4+4+5+6+6+7+8+8=50
50/9=5.55555555556

Step-by-step explanation:
Usando BODMAS, entonces que tenemos
(2 + 4 * 3) =
(2 + 12) =
