Solve for a.
a+(−1.2)=−5.5
Enter your answer in the box.
a =
Answer:
-4.3
Step-by-step explanation:
a+(-1.2)= -5.5
a-1.2=-5.5
add 1.2 to both sides
a-1.2+1.2= - 5.5+1.2
simplify
a= - 4.3
Answer:
a=-4.3
Why?:
You would have to keep the answer negative, this is because if it were to be positive it would make the negative decrease.
You could easily get a line paper and line up-
-4.3
+ -1.2
_______
-5.5
-5.5-(-1.2) would make the equation end up like -5.5+1.2, and -5.5+1.2=-4.3
Therefore,
a=-4.3

5. A quarter is tossed in the air 300 times.
About how many times would you expect the quarter to land on heads?
A 50
E 200
B 110
C 150
D 180
Answer:
C
Step-by-step explanation:
The probability of getting heads or tails is 50%.
300*50% = 150
Answer:
C. 150 times
Step-by-step explanation:
Because a coin only has tails and heads, you can say that the probability would be half. Because it was tossed 300 times, you can say: 300*0.5=150

The slope of the line that passes through the points ( 2 , 3 ) a n d ( 5 , 9 ) is?
what is the slope of the line perpendicular to AB if A(-1,10) and B(5,-2)
The slope of the line that is perpendicular to line AB is: 1/2.
Recall:
If line A has a slope of "-a" and it is perpendicular to line B, therefore, the slope of line B will be the negative reciprocal of line A which is 1/a.Slope (m) = change in y / change in x = [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]Given:
A(-1,10)
B(5,-2)
Slope of AB:
[tex]m = \frac{-2 - 10}{5 -(-1)} = \frac{-12}{6} \\\\\mathbf{m = -2}[/tex]
The slope of the line that is perpendicular to line AB will be the negative reciprocal of the slope of AB.
Therefore, the slope of the line perpendicular to AB is: 1/2.

Which ordered pair is a solution to the line whose equation is 2y=-3x-2
A.(2, -3) C. (2, -4)
B. (-3, 2) D. (-4, 2)
Answer:
The solution would be C. (2, -4)
Step-by-step explanation: Equation: 2y = -3x - 2
1. (2, -3)
2(-3) = -3(2) - 2
-6 = -6 - 2
-6 = -8 (Not a solution)
2. (-3, 2)
2(2) = -3(-3) - 2
4 = 9 - 2
4 = 7 (Not a solution)
3. (2, -4)
2(-4) = -3(2) - 2
-8 = -6 - 2
-8 = -8 (Solution)
4. (-4, 2)
2(2) = -4(-4) - 2
4 = 12 - 2
4 = 10 (Not a solution)

Is the relationship for Olivia’s puppy’s weight in terms of time linear or nonlinear? Explain your response.
Answer:
Olivia's puppy is linear i know this because after applying to the graph i got a straight line.
Step-by-step explanation:
Answer:
When looking at the table you can see that for every increase of 1 in the x value it results in an increase of 1 in the y value. The rate of change is constant.
Rate of change is calculated by the change in y/change in x
For the points (1,2), (3,3) and (5,4) the rate of change calculation would be as follows:
(1, 2)(3, 3)
3-2 / 3-1= 1/2
(3, 3)(5, 4)
4-3 / 5-3= 1/2
Since both equal 1/2 the rate of change is constant therefore making it linear.

Which point is an x-intercept of the quadratic function f(x) = (x + 6)(x – 3)?
(0,6)
(0,–6)
(6,0)
(–6,0)
Answer:
D: (-6,0)
Step-by-step explanation:
Set f(x) equal to 0 and solve for the values of x:
f(x) = (x+6)(x-3)
0 = (x+6)(x-3)
x+6=0 and x-3=0
x=-6 and x=3
Therefore, the x-intercepts are (-6,0) and (3,0). Because only (-6,0) is an option, then option D is correct.
Answer: (-6, 0)

if

then what is the answer of
[tex] \frac{a + 3c + 4}{b + 3d + 10} [/tex]
Step-by-step explanation:
Given,
a/b = c/d = 2/5
=> a + 3c + 4/b + 3d + 10
=> (a/b) + (3c/3d) + (4/10)
=> 2/5 + 3(c/d) + 4/10
=> 2/5 + 3(2/5) + 4/10
=> 2/5 + 6/5 + 2/5
=> 2 + 6 + 2/5
=> 10/5
=> 2

f(x) is linear.
g(x) is exponential.
F(x) is linear! Remember, linear functions have a set amount of rate of change, in this case it’s 2! G(x) is a exponential function because instead of going down by a certain amount, it’s simply going down by half.

Find two numbers whose sum is 36 and whose difference is 10.
Answer:
23 & 13
Step-by-step explanation:
23+13=36
Answer:
x = 23
y = 13
Step-by-step explanation:
Let the number be x and y.
As given,
x + y = 36 ---(i)
x - y = 10 ---(ii)
Adding eq(i) and eq(ii) we get,
2x = 46
x = 23
Now putting the value of x in eq(ii)
23 - y = 10
y = 13
So the two numbers are 23 and 13.

Note: I ended up with the simultaneous equations, which are correct according to the markscheme BUT the answers I got upon solving them were incorrect.
μ = 170 + 1.6449σ
μ = 180 - 0.8416σ
What I got after solving these were:
μ = 169.5306859
σ = 12.44864932
But according to the markscheme, I should have gotten:
μ = 176.615...
σ = 4.021...
Can someone explain to me where I've gone wrong?
Answer:
Yes, your simultaneous equations are correct;
Solve them like so:
170 + 1.6449σ = 180 - 0.8416
2.4865σ = 10
σ = 4.0217...
μ = 170 + 1.6449(4.0217...)
μ = 176.615...
MS is correct, you must've made an error in solving or rearranging

Nolan began a savings account three years ago. He invested $100 at a 2% interest rate according to the equation Vn = 100(1.02)x, where Vn is the value of his account after x years. Anias started an account today. She invested $100 at a 2% interest rate according to the equation Va = 100(1.02)x–3, where Va is the value of her account. Let’s say Anias started saving at the same time Nolan did, three years ago. Approximately how much money would she have had to invest to have the same amount of money she has now?

Two companies allow you to pay monthly for your food
A charges a one time fee of $150 and $45 per month Company B charges a
one time fee of $125 and $50 per
month
Answer:
A: 150+(45•p)
B: 125+(50•p)
Step-by-step explanation:
You multiply the monthly fee by a letter representing an unknown number because we dont know how many months you are staying with each company and we add the one time fee because you are only paying once, so in conclusion you add the one time fee to the result of the monthly fee by how many months.
