Answer:
The integers are 96, 97, 98, and 99
Step-by-step explanation:
first integer = x
second integer = x+1
third integer = x+2
fourth integer = x+3
(that what consecutive means, like 4, 5, 6, 7 are just adding 1 more each time
The sum (add them all up) is (=) 390 so
x+(x+1)+(x+2)+(x+3) = 390
4x+6=390
4x+6-6=390-6
4x=384
4x/4=384/4
x=96
x+1=97
x+2=98
x+3=99
The integers are 96, 97, 98, and 99

How do you solve this problem?
The product of the expressions (1/5 x - 1/4) and (2/3 x + 1) will be 2/15 x² + 1/30 x - 1/4.
What is multiplication?It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expression is given below.
(1/5 x - 1/4) and (2/3 x + 1)
Then the product of the expressions (1/5 x - 1/4) and (2/3 x + 1) will be
⇒ (1/5 x - 1/4) (2/3 x + 1)
⇒ 2/15 x² + 1/5 x - 1/6 x - 1/4
⇒ 2/15 x² + 1/30 x - 1/4

yolanda's yoga class charges a $20 membership fee and $20 per visit.
write an expression that represents the cost of "x" visits: C=_______
how many visits would it take for the two costs to be the same?
(use your expressions and make them equal to each other and solve)
The 2 expressions: 10x + 100 and 20x + 20
20x + 20:
20 dollars per visit (20x) ; 20 dollar fee (20)
10x + 100 = 20x + 20 Subtract 10x from both sides
100 = 10x + 20 Subtract 20 from each side
80 = 10x Divide by 10

Rational algebraic expressions are expressions that can be represented as a quotient of two polynomials.

Answer:
8×(−2)−(−4)^2 < 36÷9+2×5
Step-by-step explanation:
The left side expression evaluates as ...
8×(−2)−(−4)^2
= 8×(−2) − 16
= -16 -16
= -32

The right side expression evaluates as ...
36÷9+2×5

It should be no mystery that any negative number is less than any positive number:
-32 < 14
8×(−2)−(−4)^2 < 36÷9+2×5 . . . . . . . . "less than" symbol is required

The scatterplot above shows the number of wins and the attendance per game for 30 baseball teams in 2017.
Also shown are the least-squares regression line and computer output.
a) Using the information above, what is the equation of the least-squares regression line?
b) What is the value of the correlation coefficient for the sample?
c) Interpret the slope of the least-squares regression line in context.
The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values
a) The equation of the least-squares regression line is [tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]
b) The correlation coefficient for the sample is approximately 0.351
c) The slope gives the increase in the attendance per increase in wins
Reasons:
a) From the computer regression output, we have;
The y-intercept and the slope are given in the Coef column
The y-intercept = 10835
The slope = 235
The equation of the least-squares regression line is therefore
[tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]
b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229
Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351
The correlation coefficient for the sample, r ≈ 0.351
c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins

B: f (x) = x^3 + 10x^2 + 7x - 27
C: f (x) x^3 + 10x^2 + 7x - 18
D: f (x) = x^3 - 8x^2 - 11x + 27
Answer:
C. f(x) = x³ + 10x² + 7x - 18Step-by-step explanation:
If the function has a factor of x + 9, then the function will have a zero output at x = -9
Lets verify:
A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, NoB. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, NoC. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, YesD. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, NoIT'S HOMEWORK WHOEVER GIVES ME A GOOD ANSWER I WILL MAKE BRAINLIST.

Answer:
58.29 cm²
Step-by-step explanation:
Hi there!
Area of a trapezoid: [tex]A=\displaystyle \frac{a+b}{2} *h[/tex]
We're given that a = 7, b = 10.4 and h = 6.7. Plug these into the above:
[tex]A=\displaystyle \frac{7+10.4}{2} *6.7\\\\A=\displaystyle \frac{17.4}{2} *6.7\\A=8.7*6.7\\A=58.29[/tex]
Therefore, the area of the trapezoid is 58.29 cm².
