4r + 13 = -15 -3r
i dont know how to do this and its due at 4
Answer:
r = -4
Step-by-step explanation:
4r + 13 = -15 -3r
7r = -28
r = -28/7
r = -4
Answer:
r = -4
Step-by-step explanation:
4r + 13 = -15 -3r
Add 3r to each side
4r + 13+3r = -15 -3r+3r
7r +13 = -15
Subtract 13 from each side
7r+13-13 = -15-13
7r = -28
Divide each side by 7
7r/7 = -28/7
r = -4
36. A function g is described below
.
g(x) = (x - 3)2 + 1
• The domain of g is all real numbers greater than 0.
The range of g is all real numbers greater than
or equal to -
F. 1
H. -3
G. 3
J. 10
Answer: F
Step-by-step explanation:
A square is always positive:
[tex](x-3)^2 \geq 0\\\\g(x)=(x-3)^2+1 \geq 1\\\\answer\ F\\[/tex]
Answer:
F.
Step-by-step explanation:
The expression (x - 3)^2 is always >= 0.
The minimum value of g occurs when x = 3 :- that is (3-3)^2 + 1 = 1.
The range of g(x) is all real numbers >= 1.

2= 2.27- m/4
How do I do this?! I need this for mathematics homework!
Answer:
1.08 = m
Step-by-step explanation:
2= 2.27- m/4
Subtract 2.27 from each side
2-2.27= 2.27-2.27- m/4
-.27 = -m/4
Multiply each side by -4
-.27 * -4 = -m/4 *-4
1.08 = m

Which represents a unit rate ?
A. The cost of cat food is $36 per 3 bags
B. The cost of orange juice is $3 per jug
C. The cost of photocopies is $1 per 10 pages
D. The cost of roses is $50 per 2 dozen
B. The cost of orange juice is $3 per jug
A unit rate, in terms of mathematics, is a rate per unit.
Examples of unit rates are:
The car travels 25 km per hour
The cost of bags of apples is $6.00 per bag of apples.
The unit rate in these choices is Choice B:
The cost of orange juice is $3 per jug
The other choices are rates, not unit rates.
93. Let f(x) = 3x - 1 and g(x) = x + 5. Evaluate the following limits. (a) lim x→3 f(g(x)]
(b) lim x→3 g[f(x)]
Answer:
a) 23 and b) 13
Step-by-step explanation:
I. If f(g(x)) is composit function
Find fog and gof
fog = 3(g) - 1
= 3(x+5) -1
= 3x + 15 -1
= 3x + 14
gof = (f) + 5
= (3x - 1) +5
= 3x + 4
II. Fill in a) and b) question
lim x -> 3 fog
= 3(x) + 14
= 3(3) + 14
= 9 + 14
a) = 23
lim x-> 3 gof
= 3x + 4
= 3(3) + 4
= 9 + 4
b) = 13

C. Find the equation of the line perpendicular to
y = 14x-5 and passing through (2,-3).
Answer:
[tex]y = -4x + 5[/tex]
Step-by-step explanation:
We want to find the equation of the line that is perpendicular to:
[tex]\displaystyle y = \frac{1}{4} x - 5[/tex]
And which passes through the point (2, -3).
Recall that the slopes of perpendicular lines are negative reciprocals of each other.
In other words, since the slope of the original line is 1/4, the slope of the perpendicular line will be -4.
We are also given that it passes through the point (2, -3). Hence, we can consider using the point-slope form:
[tex]\displaystyle y - y_1 = m(x- x_1)[/tex]
Substitute:
[tex]\displaystyle y - (-3) = -4 (x - (2))[/tex]
Simplify:
[tex]y + 3 = -4(x - 2)[/tex][tex]y = -4x + 5[/tex]
Distribute:
[tex]y + 3 = -4x +8[/tex]
And subtract:
[tex]y = -4x + 5[/tex]
In conclusion, our equation is:
[tex]y = -4x + 5[/tex]
Use your birthday month and day only, and find the sum and the product and the difference, and quotient.
month is 3 and day is 11
Answer:

Step-by-step explanation:
Sum: add
3 + 11 = 14
Difference: subtract
3 - 11 = -8
Product: multiply
3 * 11 = 33
and quotient: divide
3 / 11

A commodity was sold for 120.00 at a 20% loss on the cost. What is the price of the merchandise?
Answer:
$150
Step-by-step explanation:
CP = 100/(100 - L%) × SP
CP = 100/(100 - 20) × 120
CP = 100/80 × 120
CP = 5/4 × 120
CP = 5 × 30
CP = $150

Hey there! I'm happy to help!
We have $100.75 to spend.
Each spool costs $3, and we have 24 spools.
3×24=72
Each glue costs $1 and we have 7 packages of glue.
7×1=7
We add up these expenses.
72+7=79
And we subtract from our total amount.
100.75-79=21.75
So, Joanna has $21.75 left after buying these things.
Have a wonderful day and keep on learning! :D
Answer:
21.75
total money she has is 100.75
1 spool of ribbon $3
she buys 24 spools = 24X3
$72
1 glue cost $1
so 7 package glue cost =7X1= $7
money that he left is equals to 100.75- 79
=21.75

Add 5 to x, double what you have, then subtract 3 from the result and simplify the expression.
a.2x + 10
b.2x + 7
c.x + 7
d.2x – 7
Only answer number 37.
Step-by-step explanation:
Use the distance formula:
(x2, y2) with (x1, y1)
[tex] d \: = \sqrt{( x2 \: - \: x1) {}^{2} \: + \: (y2 \: - \: y1) {}^{2} } [/tex]
Find the lengths of each segment one at a time.
For AC:
A(-3,8) C(0,2)
[tex]d = \sqrt{( - 3 - 0) {}^{2} + (8 - 2) {}^{2} } [/tex]
[tex]d \: = \sqrt{9 + 36} [/tex]
[tex]d \: = \sqrt{45} = 3 \sqrt{5} [/tex]
For BC:
B(6,5) C(0,2)
[tex]d \: = \sqrt{(6 - 0) ^{2} + (5 - 2) {}^{2} } [/tex]
[tex]d \: = \sqrt{36 + 9} [/tex]
[tex]d \: = \sqrt{45} = 3 \sqrt{5} [/tex]
For CD:
C(0,2) D(2,-4)
[tex]d \: = \sqrt{(0 - 2) {}^{2} + (2 - ( - 4)) {}^{2} } [/tex]
[tex]d \: = \sqrt{4 + 36} [/tex]
[tex]d \: = \sqrt{40} = 2 \sqrt{10} [/tex]
With all the segment lengths found, we can conclude that segments AC and BC have the same lengths.

550 x [tex]\frac{7}{22}[/tex] = [tex]\frac{7}{22}[/tex] x 11 x 11 + y
550 x [tex]\frac{7}{22}[/tex] x [tex]\frac{22}{7}[/tex] = 11 x 11 + y
550 = 11 x 11 + y
[tex]\frac{550}{11}[/tex] = [tex]\frac{11}{11}[/tex] x 11 + y
