Jayla says that the equation y=2x-3 matched the graph. Substitute the ordered pairs from part c into the equation to prove that jayla is correct. (3,3)(4,5)(5,7)
Given:
Jayla says that the equation [tex]y=2x-3[/tex] matched the graph.
To prove:
Jayla is correct
Solution:
We have,
[tex]y=2x-3[/tex] ...(i)
The ordered pairs are (3,3), (4,5), (5,7).
We need to substitute the ordered pairs into the equation to prove that Jayla is correct.
For point (3,3), put x=3 and y=3 in (i).
[tex]3=2(3)-3[/tex]
[tex]3=6-3[/tex]
[tex]3=3[/tex]
[tex]LHS=RHS[/tex]
So, point (3,3) lies on the line [tex]y=2x-3[/tex].
For point (4,5), put x=4 and y=5 in (i).
[tex]5=2(4)-3[/tex]
[tex]5=8-3[/tex]
[tex]5=5[/tex]
[tex]LHS=RHS[/tex]
So, point (4,5) lies on the line [tex]y=2x-3[/tex].
For point (5,7), put x=5 and y=7 in (i).
[tex]7=2(5)-3[/tex]
[tex]7=10-3[/tex]
[tex]7=7[/tex]
[tex]LHS=RHS[/tex]
So, point (5,7) lies on the line [tex]y=2x-3[/tex].
All three point (3,3), (4,5), (5,7) satisfy the given equation.
Therefore, jayla is correct. Hence proved.

How do you solve (8x ^5) ^2
Answer:
64x^10
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
___
Using the first rule, we have ...
(8x^5)^2 = (8^2)((x^5)^2) = 64(x^5)^2
Using the second rule, we have ...
=64x^(5·2) = 64x^10

Question 3 of 8 Solve the equation below. 6/x^2+2x-15+7/x+5=2/x-3
I assume the equation is
[tex]\dfrac6{x^2+2x-15}+\dfrac7{x+5}=\dfrac2{x-3}[/tex]
Notice that
[tex]x^2+2x-15=(x+5)(x-3)[/tex]
so to get each fraction to have a common denominator, we need to rewrite
[tex]\dfrac7{x+5}=\dfrac{7(x-3)}{(x+5)(x-3)}=\dfrac{7x-21}{x^2+2x-15}[/tex]
and
[tex]\dfrac2{x-3}=\dfrac{2(x+5)}{(x+5)(x-3)}=\dfrac{2x+10}{x^2+2x-15}[/tex]
So we have
[tex]\dfrac6{x^2+2x-15}+\dfrac{7x-21}{x^2+2x-15}=\dfrac{2x+10}{x^2+2x-15}[/tex]
Combine the fractions and put them on one side:
[tex]\dfrac{6+(7x-21)-(2x+10)}{x^2+2x-15}=0[/tex]
If x ≠ -5 and x ≠ 3, we can ignore the denominator, leaving us with
[tex]6+(7x-21)-(2x+10)=0[/tex]
[tex](6-21-10)+(7x-2x)=0[/tex]
[tex]-25+5x=0[/tex]
[tex]5x=25[/tex]
[tex]x=\dfrac{25}5=\boxed{5}[/tex]

Use the number line to represent. -4 1/2 + 3 1/4. what is the sum?
Answer:
[tex]\displaystyle A+B=-\frac{5}{4}[/tex]
Step-by-step explanation:
The Number Line
Let's call
[tex]\displaystyle A=-4\frac{1}{2}[/tex]
[tex]\displaystyle B=+3\frac{1}{4}[/tex]
Both numbers are given as mixed fractions. Let's convert them to improper fractions:
[tex]\displaystyle A=-4\frac{1}{2}=-(4+\frac{1}{2})=-\frac{8+1}{2}=-\frac{9}{2}[/tex]
[tex]\displaystyle B=3\frac{1}{4}=3+\frac{1}{4}=\frac{12+1}{4}=\frac{13}{4}[/tex]
The decimal values are A = -9/2=-4.5, B=13/4 = 3.25
Now represent the points in the number line. See the image below
Finally, calculate their sum:
[tex]\displaystyle A+B=-\frac{9}{2}+\frac{13}{4}[/tex]
[tex]\displaystyle A+B=-\frac{18}{4}+\frac{13}{4}=\frac{-18+13}{4}[/tex]
[tex]\boxed{\displaystyle A+B=-\frac{5}{4}}[/tex]

If g(x) = {(4, -5), (-3, 2), (-6, 1), (1,0)}, which set of ordered pairs represents
the inverse of g(x)?
O A. {(-5, 4), (2, -3), (1, -6), (0, 1)}
O B. {(-4,5), (3, -2), (6, -1), (-1,0)}
O C. {(5, -4), (-2,3), (-1,6), (0, -1)}
O D. {(4, -5), (-3,2), (-6, 1), (1, 0)}
Answer:
The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)
Step-by-step explanation:
To find the inverse of a function switch x and y
Example:
If f(x) = {(1, 2), (-4, 5), (0, 0)}
To find its inverse switch x and y in each ordered pair
The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}
Let us do the same with our question
∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}
→ Switch x and y coordinates in all ordered pair
∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}
Look at the answer to find the correct choice
It is (A)
Answer:
A. {(-5, 4), (2, -3), (1, -6), (0, 1)}
Step-by-step explanation:

A baby blue whale can gain up to 200 pounds a day after it is born. If a baby blue whale has gained 7 x 103 pounds since its birth, how many days old is it?Express your answer
in standard notation.
Answer:
35 days
Step-by-step explanation:
Weight gain per day = 200 pounds
Weight gained by a whale since birth = [tex] 7*10^3 [/tex] pounds
Number of days of the whale = [tex] \frac{7*10^3}{200} = \frac{7*10*10*10}{200} [/tex]
[tex] = \frac{7*1000}{200} = \frac{7000}{200} = \frac{70}{2} = 35 [/tex]
In standard notation form, the whale is 35 days old.
