Answer:
21 and 16
Step-by-step explanation:
x= big number
x`-5 = small number
x + x-5 = 37
2x-5 =37
2x= 42
x = 21
21-5 = 16
21+16 = 37

Evaluate the following:
F(x) = 4x - 9 for f(5)
Answer:
f(5)=11
Step-by-step explanation:
f(x)=4x-9
f(5)=4(5)-9
f(5)=20-9
f(5)=11
Answer:
f(5) = 11
Step-by-step explanation:
F(x) = 4x - 9 for f(5)
x gets replaced with 5
f(5) = 4(5) - 9
f(5) = 20 - 9
f(5) = 11
Zina goes shopping. She buys in the same store two scarves and three T-shirts for
49 euros. A week later, it was the sales: reduction of 1.5 euros on scarves and 2 euros
on t-shirts. Zina took the opportunity and for 40 euros, she was able to buy four scarves and five T-shirts.
What was the price of a scarf and a T-shirt before the sales?
THX FOR HELPING!
Answer:
The price of T-shirts before the sale = 42 euros
The price of scarves before the sale = -77/2 euros
Step-by-step explanation:
The cost of the items Zina buys from the store initially are;
Two scarves and three T-shirts for 49 euros
The reduction in the price of scarves a week later during sales = 1.5 euros
The reduction in the price of T-shirts a week later during sales = 2 euros
The items Zina bought for 40 euros at the reduced price of the sales opportunity are;
Four scarves and five T-shirts for 40 euros
Let 'x' represent the initial price of a scarf and let 'y' represent the initial price of a T-shirt, we have;
2·x + 3·y = 49...(1)
4·(x - 1.5) + 5·(y - 2) = 40...(2)
Expanding equation (2) gives;
4·x - 6 + 5·y - 10 = 40
4·x + 5·y = 40 + 6 + 10 = 56
∴ 4·x + 5·y = 56...(3)
By multiplying equation (1) by 2 and subtracting the result from equation (3), we get;
4·x + 5·y - 2 × (2·x + 3·y) = 56 - 2 × 49 = -63
-y = -42
y = 42
The price of T-shirts before the sale = 42 euros
x = (49 - 3 × 42)/2 = -77/2
x = -77/2
The price of scarves before the sale = -77/2 euros
(However, if the had bought the 4 scarves and 5 T-shirts during sales at 70 euros, we get;
The price of T-shirts before the sale = 12 euros
The price of scarves before the sale = 6.5 euros.
The allowable total price for the reduced 4 scarves and 5 T-shirts is between 66 and about 82 for both initial prices to be +ve)

What number is represented by point P?
Answer:
0.0057
Step-by-step explanation:
Narrow it down.The point P is between 5 * 10^-3 and and 6*10^-3When you go to the bottom line, P is on the 7th division from the left. Going from left to right increases PP is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.One of the answers is 5.7 * 10^-3The other answer is .0057I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it. If it is not correct, then 5.7 * 10^-3 is the answer.which throw is nearest to 71.1m? 71.8m, 71.08m, 71.82m, 71.79m, 72m
Answer:
71.08 is the closest
Step-by-step explanation:
71.8 is .7 away
71.08 is .02 away
71.82 is .72 away
72 is .9 away

Answer:
x=-4
Step-by-step explanation:
The axis of symmetry is the x-value where the two “curves” of the parabola start at. For this parabola, the curves start at x=-4 and extend outward. So, the axis of symmetry is x=-4.
Answer:
x = -4
Step-by-step explanation:
The axis of symmetry is a vertical line thru the vertex. The vertex is (-4, 2).
So, the line of symmetry is x = -4

Construct the graph of the following function and identify its zeros on the same document. f(x) = (-x + 2)(x + 1)(x +2). Upload your document in the box below.
Answer:
Given function:
f(x) = (-x + 2)(x + 1)(x +2)We can rewrite it as:
f(x) = - (x - 2)(x + 1)(x +2)Zeros are:
- (x - 2)(x + 1)(x +2) = 0x - 2 = 0 ⇒ x = 2x + 1 = 0 ⇒ x = -1x + 2 = 0 ⇒ x = -2As leading coefficient is negative the function is decreasing.
As the function is of degree 3, it is odd.
Considering the above two factors we can define the shape of the graph:
It is decreasing function with one local minimum and one local maximum.See the graph and zero's reflected.
Analyze the function:
[tex]f(x) = \\ ( - x + 2)(x + 1)(x + 2)[/tex]
Write properties of function:
Solution:
x-intercept/zero
[tex] {x}^{1} = - 2 \\ {x}^{2} = - 1 \\ {x}^{3} = 2[/tex]
y-intercept:
[tex]y = 4[/tex]
domain:
[tex]( - \infty \: . \: + \infty )[/tex]
type of function:
[tex]cubic \: function[/tex]
standard form:
[tex]f(x) = - {x}^{3} - {x}^{2} + 4x + 4[/tex]
factorized form:
[tex]f(x) = - ( - (x + 1)( x + 2) ( - 2x + 2))[/tex]
even/odd:
[tex]neither[/tex]
bounce/cross x-axis:
[tex]x = - 2 \: . \: cross \: . \: x = - 1 \: . \: cross \: . \: x = 2 \: . \: cross[/tex]

ΔABC≅ΔDEC by AAS
Step-by-step explanation:
You can use the AAS method of congruency.
Since you already have <BAC and <EDC congruent to eachother, and sides BC and EC congruent to each other, you only need that one remaining angle in between. <ACB can be proven congruent to <DCE by the Vertical Angles Theorem, and that gives you the AAS you need to prove that these two triangles are congruent

A man bought a car for $8,200 and sold it for 80% of the price two years later. How much did he lose?
I need help, and a step by step explanation! :)
Answer:
90°
Step-by-step explanation:
There is no work. We know the right angle in the triangle and the x are supplementary. Meaning, they add up to 180 degrees. Therefore, 180-90 = 90. Think of it as a full triangle. If the 40 at the top was not half, but a full triangle, the 40 at the top would become 80. The 50 in the bottom left would mean there would be a 50 in the bottom right when you mirror the triangle. Therefore, you also need x to be 90 to make it a right triangle.

If a box has 5 red, 3 green, and 4 blue jelly beans, then what is the probability of choosing
at random a red jelly bean?
7/12, 5/12, 1/12, 2/7
Answer:
2/7
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
All the beans are equally likely to be chosen, so the bottom (denominator) of the fraction is 12 (there are 12 beans in the box).
The numerator is 5 because that's the number of red beans in the box.

For each given sequence: write down term to term rule and position to term rules 2,5,8,11,14
Answer:
Tn = 3n + 1
Step-by-step explanation:
The given sequence 2,5,8,11,14 is an arithmetic sequence
The nth term of an arithmetic sequence is expressed as;
Tn = a + (n-1)d
a is the first term
d is the common difference
n is the number of terms
Given
a = 2
d = 5-2 = 8-5 = 3
Substitute into the formula
Tn = 2 + (n-1) * 3
Tn = 2 + 3n - 3
Tn = 3n + 1
This gives the term rule for the sequence
