Here's the solutions :
1. solve for a :
[tex]4a = 20[/tex][tex]a = \dfrac{20}{4} [/tex][tex]a = 5[/tex]2. solve for y :
[tex]3y + 9 = 24[/tex][tex]3y = 24 - 9[/tex][tex]3y = 15[/tex][tex]y = \dfrac{15}{3} [/tex][tex]y = 5[/tex]3. solve for y :
[tex] \dfrac{y}{3} - 5 = 4[/tex][tex] \dfrac{y}{3} = 5 + 4[/tex][tex] \dfrac{y}{3} = 9[/tex][tex]y = 9 \times 3[/tex][tex]y = 27[/tex]4. solve for k :
[tex]3 = 9 - 4k[/tex][tex]3 - 9 = -4 k[/tex][tex] - 6 = - 4 k[/tex][tex]k = \dfrac{ - 6}{ - 4} [/tex][tex]k = \dfrac{3}{2} \: \: \: or \: \: 1.5[/tex]5. there's something wrong with this question.

A ice cream cone cost $3 plus an additional $0.50 per scoop. James pald a total of $4.50, which equation below
models this situation.
4.50 + 0.50x = 3
0.50x + 3 = 4.50
0.50x = 7.50
3x + 0.50 = 4.50
Answer:
B: 0.50x + 3 = 4.50
Step-by-step explanation:
James needed an additional 3 scoops so the x would have to be on $0.50. the $3 is what the cone cost so it has to be with the scoop price. $4.50 is the total price of the ice cream so that would be on the other side of the equal sign, resulting in 0.50x + 3 = 4.50

Please solve ASAP. Solving quadratic equations by factorising
Answer:
x = 1 , x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
2x² - 5x + 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 3 = 6 and sum = - 5
The factors are - 2 and - 3
Use these factors to split the x- term
2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )
2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x - 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

hi can someone please answer my question i really need the complete step-by-step solution. thank you ❤️
Answer:
this sequence is geometrical sequence
and it's formula is
[tex]y = a {r}^{n} \\ here \: a \: is \: first \: number \: is \: equal \: 1 \\ and \: the \: ratio \: is \: r \: is \: equal \: - 3 \\ y = 1 \times {( - 3)}^{n} [/tex]
Find the sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2.
The sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2 is: -637.5
The nth term of a geometric sequence is given mathematically as;
T(n) = ar^n
where, a = first term of the geometric sequence.r = common ratio of the sequenceand n = nth term of the sequence.Therefore, the sum of the first 8 terms of the geometric sequence is;
S(8) = a + ar + ar² + ar³ + ar⁴ + ar⁵ + ar⁶ + ar⁷.
In essence;
since common ratio, r = 2 and first term, a = -2.5Therefore, we have;
S(8) = -2.5(1 + 2 + 2² + 2³ + 2⁴ + 2⁵ + 2⁶ + 2⁷)S(8) = -2.5(255)S(8) = -637.5.
Therefore, the sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2 is: -637.5

Could a triangle have angle measures of 94°, 106°, and 11° EXPLAIN HOW YOU KNOW.
Answer:
Nope
Step-by-step explanation:
All angles have to measure up to where adding up two of any angles will result in a number greater than or equal to the angle that was not added.
But here if we add up 94° and 11°, we end up with 105°.
Since 105° is lower than the angle not added, which is 106°, this triangle cannot exist.

A polynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. If the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?
The graph of the function is positive on (–6, –2).
The graph of the function is negative on (negative infinity, 0).
The graph of the function is positive on (–2, 4).
The graph of the function is negative on (4, infinity).
Answer:
A. The graph of the function is positive on (–6, –2)Step-by-step explanation:
