Answer:
Step-by-step explanation:
f ( x ) = 17 ( 3 + x )
f ( -2 ) = 17 ( 3 + -2 )
f ( -2 ) = 51 + -34
f ( -2 ) = 17
= 17
Find the value of x in the diagram below:
Answer:
X = -4
Step-by-step explanation:
Because both sides are equals, then:
X-3 = 2X-7
2X-X = -7+3
X = -4
Find the unit rate.
350 papers for $140
Answer:
2.5
Step-by-step explanation:
take the number of papers and divide it by cost to determine the number of papers/dollar
350/140
(kinda like a fraction, ima just simplify to make it easy to see the answer)
35/14
5/2
2 1/2
Hope This Helps
Answer:
2.5 is the answer
Step-by-step explanation:
State the property being illustrated in each example.
5.) 6(5x) = (6.5)x
6.) 14 + x + 8 = 14 + 8 + x
7.) 9(y + 4) = 9y + 36
8.) (a + 100) + 50 = a + (100 + 50)
9.) 1/4 (8x - 20) = 2x-5
10.) 25 - 7 = 25 .7 . y
Answer:
5.) Associative Law
6.) Commutative Law
7.) Distributive Law
8.) Associative Law
9.) Distributive Law
10.)
Step-by-step explanation:
The associative law means that if all the arithmetic operations in an equation are the same, the position of the brackets do not matter and no matter which variables are associated, the result would still be the same.
The commutative law means that if all the arithmetic operations in an equation are the same, the position of the variables do not matter and no matter what order the variables are placed, the result would still be the same.
The distributive law means that whatever is outside of the bracket has to be multiplied into the variables in the bracket evenly. E.g. 1/4 (8x - 20) involves multiplying both 8x by 1/4 and 20 by 1/4.

Patti got a new part-time job. Her hourly wage increased from $10.50 to $12.39. What was the percent increase in Patti's hourly wage?
Answer:
18%
Step-by-step explanation:
Subtract $10.50 from $12.30 and you will get 1.8.
Then divide 1.8 to 100 (because 100% = total) and you will get 0.018 which means 18%. Her hourly wage increased by 18%.
The perimeter of a rectangle can be found using the formula 2l + 2w, where l represents the length of the rectangle and w represents the width of the rectangle. Find the perimeter of a rectangular swimming pool whose length is 32 feet and width is 20 feet.
Answer:
The perimeter is 104
Step-by-step explanation:
The formula for a peremeter is 2 * length + 2 * width.
Substitute the length and width for the given values.
2 * length + 2 * width
2 * 32 + 2 * 20
64 + 40
104

Answer:
The sum of the interior angle measures of the polygon is 540°
Step-by-step explanation:
The formula of the sum of the measures of the interior angles of a polygon is
∑m = (n - 2) × 180°, where n is the number of the sides of the polygon
In the given figure
∵ The polygon has 5 sides
∴ n = 5
→ Use the formula above to find the sum of the interior angle measures of it
∵ ∑m = (5 - 2) × 180°
∴ ∑m = 3 × 180°
∴ ∑m = 540°
∴ The sum of the interior angle measures of the polygon is 540°
Ben needs to replace two sides of his fence. Once side is 367 9/100 meters long, and the other is 329 3/10 meters long. How much fence does Ben need to buy?
Answer:
696 39/100
Step-by-step explanation:
Review the following information about vectors q and r.
What is the value of a?
q=(-4,1)
31
r = (a, 3)
7(q + r) = (-35, 28)
-5
==========================================
Work Shown:
q = (-4, 1) is one vector
r = (a,3) is another vector
The resultant vector is
q+r = (-4,1)+(a,3)
q+r = (-4+a,1+3)
q+r = (-4+a,4)
Multiply both sides by 7
7(q+r) = 7*(-4+a,4)
7(q+r) = (7*(-4+a),7*4)
7(q+r) = (-28+7a, 28)
---------------
Since 7(q+r) = (-35, 28), we know that,
(-28+7a, 28) = (-35, 28)
which leads to
-28 + 7a = -35
when we equate the x components of each vector. Let's solve for 'a'
-28 + 7a = -35
7a = -35+28
7a = -7
a = -7/7
a = -1
--------------
Check:
q = (-4,1)
r = (a,3) = (-1,3)
q+r = (-4,1)+(-1,3)
q+r = (-4+(-1), 1+3)
q+r = (-5, 4)
7*(q+r) = 7*(-5, 4)
7*(q+r) = (7*(-5), 7*4)
7*(q+r) = (-35, 28)
The answer is confirmed.

Answer:
84
Step-by-step explanation:
Answer:
If you meant 3 [ ( 15-3 ) 2 ] + 4, the answer should be 73.
Step-by-step explanation:
3 [ ( 15-3 ) 2 ] + 4
= 3 [ ( 12 ) 2 ] + 4
= 3 [ 24 ] + 4
= 69 + 4
= 73
Brianna spent $15.00fot 6 two-litter sodas for a football game this weekend. What is the number of soda bottles that could be bought for $55.00
Answer:
22
Step-by-step explanation:
1. Divide $15 by 6 first to get the unit price per bottle.
$15/6= $2.50
2. Now divide the new dollar amount by the unit price.
$55.00/2.50 = 22

19) Geoff owns a computer store in 1990 he sold 2400 monitors and in 2000 he sold 4000. Let x
represent the number of years since 1990. Write a linear equation in slope intercept form that
represents this data.
Answer:
B. [tex] y = 160x + 2400 [/tex]
Step-by-step explanation:
The linear equation for that represents the above data is given in slope-intercept form as [tex] y = mx + b [/tex], where:
m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
b = starting value = y-intercept = 2,400
Slope of the linear equation using (0, 2400) and (10, 4000):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4000 - 2400}{10 - 0} = \frac{1600}{10} = 160 [/tex]
Substitute m = 160, and b = 2,400 in [tex] y = mx + b [/tex].
Thus, the linear equation in slope-intercept form would be:
✅[tex] y = 160x + 2400 [/tex]

a relation is defined by the points (1,4), (3,-1), (-1,-2) and (1,-3)
this relation (is) (is not) a function because there (is no x-value) (is one x-value) (are two x-values) corresponding to multiple y-values.
Answer:
The answer is that the relation is not a function. because there are two x-values corresponding to multiple y-values
Step-by-step explanation:
Here we want to explain why the given set of points do not represent a function
For a function, we can have same y value for different x value
But, we cannot have same x value for different y value
The sets of point given however has 2 y-values having same x value and as such the points cannot form a function (1,4) and (1,-3)
