Answer:
15
Step-by-step explanation:
If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,
4x-6+x=69
5x-6=69
5x=75
x=15
So, Maggie is 15.
Answer: Maggie is 15 years old
Step-by-step explanation:
69 = (4m - 6) + m --- get an equation
69 - m = 4m - 6 --- lets subtract m from both sides first
75 - m = 4m --- add 6 on both sides
75 = 5m --- add m on both sides
15 = m --- divide by 5 on both sides
m = 15, so Maggie is 15 years old
Let's check:
69 = (4(15)-6) +15
69 = (60 - 6) + 15
69 = 54 + 15
69 = 69

Which of the following could be the quadratic function graphed in the xy-plane above?
f(x) = 2x2
f(x) = x2 + 1
f(x) = (x - 2)2 + 1
f(x) = (x - 1)2 + 2
Answer:
the correct answer is f(x)=(x-2)^2 + 1
Step-by-step explanation:
lets loof for f(2) :
f(2)=(2-2)^2 + 1
f(2)=(0)^2 + 1
f(2)= 1 ---> (2,1)

The length and width of a rectangle are in a ratio of 7:11. If the perimeter of the
rectangle is 72 cm. Find the
length and
width of the rectangle.
Answer:
14cm and 22cm
Step-by-step explanation:
Given parameters:
Perimeter of rectangle = 72cm
Ratio of length to width = 7: 11
Unknown:
Length and width of the rectangle = ?
Solution:
Since the ratio of length to width is 7: 11,
if the length is 7x , width = 11x
The perimeter of a rectangle can be obtained using
Perimeter = 2(L + W)
Insert the parameters and solve;
72 = 2(7x + 11x )
72 = 2(18x)
x = [tex]\frac{72}{36}[/tex] = 2
The length = 7x = 7x2 = 14cm
width = 11x = 11 x 2 = 22cm
A zoo collected data on the diving times of turtles. Based on the data, the regression line is j = 0.010 + 2.515x, where x is the time of the dive, in minutes. Based on the regression equation, what is the predicted dive depth in meters at 150 seconds? Give your answer to three decimal places. meter(s)
Answer:
6.298 meters
Step-by-step explanation:
Here, we are told that x is the time of the dive in minutes.
We simply first need to convert 150 seconds to minutes before substitution into the regression formula;
Kindly recall that 60 seconds = 1 minute
So 150 seconds will be 150/60 = 2.5 minutes
We now proceed to substitute into;
j = 0.010 + 2.515(x)
i = 0.010 + 2.515(2.5)
j = 0.010 + 6.2875
j = 6.2975 which go 3 decimal places is 6.298 meters
Using the regression model given, substitution the value of x = 2.5 minutes into the equation, the dive depth obtained ls 6.2975 meters.
Given the regression model :
y = 0.010 + 2.515xx = time of the dive ; y = dive depthConverting, x to minutes :
150 seconds = (150 ÷ 60) = 2.5 minutes
The dive depth, y after 150 seconds, can be obtained by substituting the value x = 2.5 into the equation :
y = 0.010 + 2.515(2.5)
y = 0.010 + 6.2875
y = 6.2975
There, the dive depth after 150 seconds will be 6.2975 meters

Find x and y. Need answer ASAP!!!
Answer:
x = 16, y = 23
Step-by-step explanation:
Consider angles related to the parallel lines and the left transversal
4x + 4 and 7x - 44 are alternate exterior angles and congruent , thus
7x - 44 = 4x + 4 ( subtract 4x from both sides )
3x - 44 = 4 ( add 44 to both sides )
3x = 48 ( divide both sides by 3 )
x = 16
----------------------------------------------------------
Consider angles related to the parallel lines and the right transversal
39 and 8y - 43 are same- side exterior angles and supplementary, thus
39 + 8y - 43 = 180 , that is
8y - 4 = 180 ( add 4 to both sides )
8y = 184 ( divide both sides by 8 )
y = 23
Can someone help me with these questions please?
Answer:
Then the best way to phrase it would be to jump right into the question without I need your help, because saying so makes it sound as though you have more of an urgent, sensitive, personal problem than a simple question or two (they might be a bit taken aback by the phrase).
However, if you have several questions (let's say more than 2), or if you just want to sound a bit more polite, you could preface the content with a phrase like I was wondering I you might be able to answer a few questions of mine, or, I have a few questions that I was hoping you might be able to help me with.

how do you do this step by step
Answer:
x = 12
Step-by-step explanation:
30 degrees and 4x+2 are equal to 8+6x
First, write a formula or expression:
30 + 4x+2 = 8+6x
simplify this by collecting like terms
32 + 4x = 8+6x (minus 6x from both sides)
32 - 2x = 8 (minus 32 from both sides)
-2x = -24 (divide by -2)
x = 12
now sub into the formula:
30 + (4 × 12 +2) = 8 + 6 × 12
80 = 80

Step-by-step explanation:
Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...
(2x -1)(3x -1) = 0 ⇒ roots 1/2, 1/3
Then the factoring of the equation with reciprocal roots is ...
(x -2)(x -3) = 0

Jason spent a total of $131 on shirts. Dress shirts cost $28 dollars and T-shirts cost $15 dollars. If he brought 7 shirts how many of each kind did he buy?
Answer: 28x + 15y = 131 and x + y = 7 where x is the number of Dress shirt and y is the number of T-shirt.
Step-by-step explanation:
We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.
We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal 131. Also, he bought 7 total shirts so x plus y has to equal 7.
28x + 15y = 131
x + y = 7
Note: it says don't solve so I didn't solve but if you want to solve use these equations.
