Answer:
x= -5 x= -6
Step-by-step explanation:
x intercepts means y is equal to zero so solve as a quadratic
= (x + 6) (x + 5)
so x = -5 and -6
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains
Answer:
225 milliliters
Step-by-step explanation:
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains. how much slushy was originally in the cup?
let x = slushy originally in the cup
total slushy consumed in 17 seconds = 17 x 4.5 = 76.5 ml
x - 76.5 = 148.5
collect like terms
x = 148.5 + 76.5
x = 225 ml

Using the line of best fit, estimate a person hourly rate when he or she had 5 years of experience ?
A.$11
B.$12
C.$13
D.$14
30 points !!!
Answer: A.)$11
Step-by-step explanation: I did the test
From the graph of the regression model given, the estimated hourly rate for an individual with 5 years experience would be $11.
The graph models the relationship between hourly rate and years of experience. The point of intersection of the y and x axis on the regression line gives the pair of points.Hence, the value of y, when x = 5 on the regression line is $11.

Answer:
here, suppose the missing length be X
hy ^2 = (one side square )^2 +(Other side square)^2
29^2= X^2 + 21^2
841 = X^2 + 441
X^2 = 841 - 441
X^2 = 400
X = 20 .........taking square root both side
the value is missing side length is 20 .
Which expression is equivalent to 2(x2 – 1) + 3x(x – 4)?
(1) 5x2 – 5
(3) 5x2 – 12x – 1
(2) 5x2 - 6
(4) 5x2 – 12x – 2
The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2
How to find equivalent expression?
The equivalent expression of the expression can be found as follows;
2(x² – 1) + 3x(x – 4)
open the brackets
2x² - 2 + 3x² - 12x
Therefore, let's combine like terms
2x² + 3x² - 12x - 2
Let's do the arithmetic for like terms
2x² + 3x² - 12x - 2
5x² - 12x - 2
Therefore, the equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
Mia took 20 seconds to run 100m. Find the ratio of distance traveled to the time Emma took to run 100m.
Answer:
The ratio should be 100 : 20. If it needs to be simplified then 5:1
Step-by-step explanation:
100 m is the distance traveled and the time it took was 20 seconds. Divide both sides by 20 and you get 5:1
(If it doesn't need to be simplified then 100 : 20)

-7x - 2y = 14
6x + 6y = 18
Answer:
x=-4, y=7
Step-by-step explanation:
Answers : x = (15/6), y =
(1/2).
Step-by-step explanation:
Explanation: To solve this equation through elimination, you need to isolate one of the variable. You can isolate the y variable since the x variables can be subtracted and go away. Add the two equations to get rid of one variable. (6x + 6y = 18) + (-6 + 2y = -14) = (8y = 4). Now you need to solve for y. y = 4/8, y = 1/2. Now, plug the y back into one equation and solve for x. 6x + 6(1/2) = 18. 6x + 3 = 18. 6x = 15. x = 15/6. Plug the two answers back in to the equation to check your answers. 6(15/6) + 6(1/2) = 18, 15 + 3 = 18. -6(15/6) + 2(1/2) = -14, -15 + 1 = -14.
If sin θ = 1 over 4 and tan θ > 0, what is the value of cos θ? (1 point)
Group of answer choices

square root of 15 over 4
square root of 15
negative square root of 15
Answer:
There are two options: b) [tex]\frac{\sqrt{15}}{4}[/tex], c) [tex]\sqrt{15}[/tex].
Step-by-step explanation:
By Trigonometry, we know that function tangent is equal to the following identity in terms of functions sine and cosine:
[tex]\tan \theta = \frac{\sin \theta}{\cos \theta}[/tex] (1)
If we know that [tex]\tan \theta > 0[/tex] and [tex]\sin \theta = \frac{1}{4}[/tex], then [tex]\cos \theta > 0[/tex]. Hence, we have two possibilities: b) [tex]\frac{\sqrt{15}}{4}[/tex], c) [tex]\sqrt{15}[/tex].
