Step-by-step explanation:
p(x) = 6x - 5 but p(x) = 13
=> 6x - 5 = 13
<=> 6x = 18
<=> x = 18 : 6 =3

Plz help I'm so dumb -_-
Please help! Will give 10 points and brainliest to first...only need 2,4,6,8
Answer:
Step-by-step explanation:
2: 1:4 scale factor
4: 4/5 = x/15. 5x=60. x is 12
6: it's a 2:7 ratio. so x would be 8 and y would be 35
8... it's a 4:7 ratio, as both 52 and 91 are divisible by 13 so there's the scale factor
4/7=x+3/2x-1. 7x+21=8x-4
Like terms on both sides
x=25

Could someone help me with these please? I’m stuck.
Answer:
1. 23
2. 5.83 (5.8 rounded)
3. 1.18 (or 1.2 rounded)
4. unsure how to solve, sorry
Step-by-step explanation:
your formula: a^2+b^2=c^2
1. 20^2+13^2=c^2
400+169=569
(take the square root of 569)
c=23
2. 15^2+b^2=17^2
225+b^2=289
(subtract 225 from both sides)
b^2= 34
(take the square root of 34)
b=5.83 (or 5.8 rounded)
3. 0.2^2+b^2=1.2^2
0.04+b^2=1.44
(subtract 0.04 from bot sides)
b^2=1.4
(take the square root of 1.4)
b=1.18 (or 1.2 rounded)
4. unsure how to solve, sorry

Janice is babysitting this summer. She already has $35 in her account before
she begins babysitting. If she makes $25 each week, how much does she have after 3 weeks?
Answer:
110
Step-by-step explanation:
well if she has 35 in her account already and she babysits for 3 weeks and makes $25 each week that would be 25 times 3 or 25+25+25=75 then you would add 75 to 35 witch is 110
Determine whether each expression is a polynomial. If so, identify the polynomial
as a monomial, binomial, or trinomial.
Answer:
1. is monomial
2. is binomial
3. is binomial
4. is trinomial
5. is trinomial
6. is binomial
Step-by-step explanation:
See...you need to know that the polynomial is determined by the number of unlilke terms in the expresion. i.e number of terms left that cant ne add subtracted or simplified anymore.
if its helpful send more quest om this...and domt forget brainliest
The expression shown are 1. Monomial 2. Not a polynomial 3. Binomial 4. Trinomial 5. Not a polynomial 6. Binomial
What is Polynomial?Polynomials are expressions of the form,
a₀ + a₁ x + a₂ x² + ................. + aₙ₋₁ xⁿ⁻1 + aₙ xⁿ
where a's are the coefficients, x is the variable and n is the number of terms.
1. 36
36 can be written as 36 x⁰.
This is a constant polynomial.
Since there is only one term, it is monomial.
2. [tex]\frac{3}{q^{2} }[/tex] + 5
This can be written as 3 q⁻² + 5.
The exponent of the variable is not a whole number, so is not a polynomial.
3. 7x - x + 5
This can be written as 6x + 5.
This is a polynomial and is binomial since there are two terms.
4. 8g²h - 7gh + 2
This is a polynomial in two variables.
This is a trinomial, as there are three terms.
5. [tex]\frac{1}{4y^{2} }[/tex] + 5y - 8
This can be written as 1/4 y⁻² + 5y - 8
This is not a polynomial as the exponent is not a whole number.
6. 6x + x²
This is a polynomial.
It is a binomial.
Hence four of the expressions shown are polynomials.

Kai took five tests this semester. His scores are listed below.
92, 88, 90, 96, 84
What is the mean absolute deviation of Kai's test scores?In decimals
Answer:
3.2 0w0, hope this helps!
Step-by-step explanation:
I did this before
The mean absolute deviation of kai's test scores is 3.2.
What is mean absolute deviation?
The mean absolute deviation of a dataset is the average distance between each data point and the mean.
According to the given question
We have
the given data 92, 88, 90, 96, 84
For calculating mean absolute deviation
we will first calculate mean
mean = [tex]\frac{92+88+90+96+84}{5} =\frac{450}{5} = 90[/tex]
Now we will calculate the distance between each data point and the mean :
|92 -90| =2|88-90| =2|90-90| =0|96-90| = 6|84 -90| = 6Add the distances together
2+2+0+6+6 = 16
Divide the sum by number of data points.
MAD( mean absolute deviation ) = [tex]\frac{16}{5} =3.2[/tex]
Hence, the mean absolute deviation of Kai's test scores is 3.2.

Scientists from different fields are trying to understand how the global climate is reacting to the changes caused in nature, and by human activities. They have come up with conflicting interpretations. Which of these is the most likely outcome of differences in interpretations made by scientists on the issue of global climate? All old ideas would be discarded. Scientific evidence would be weakened. Scientists would look for new evidence. The limitations of science would be evident.
Answer:
Scientists would look for new evidence.
Step-by-step explanation:
Anytime scientists have different interpretations, they carry out more experments to look for new evidence. But this is after they must have tested their own hypothesis. If non of these are possible, they set out to get fresh evidences. Having different opinions would make them come up with new ideas with hope that their theories are valid. And it would also make them carry out more experiments for confirmation or for denial.

Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
Step 1: Write equation
x² + 9x + 9 = 0
Since we cannot factor the expression, we will have to use the quadratic formula.
Step 2: Define
a = 1
b = 9
c = 9
Step 3: Solve for x
