Answer:
6x = - 21
Step-by-step explanation:
Given
3x - 7 = 5x ( subtract 3x from both sides )
- 7 = 2x
Then
6x = 3 × 2x = 3 × - 7 = - 21

Jalen is computing the slope of the line on the graph below.
On a coordinate plane, a line goes through points (negative 4, 0) and (2, 3).
Step 1: (–4, 0) and (2, 3)
Step 2: StartFraction negative 4 minus 2 Over 0 minus 3 EndFraction
Step 3: StartFraction negative 6 Over negative 3 EndFraction
Step 4: The slope is 2.
Which statement describes Jalen’s error?
Jalen computed the ratio of change in x to change in y.
Jalen used the ordered pairs in the wrong order.
Jalen made a computational error.
Jalen used an ordered pair that is not on the line.

Given that (-1,-1) is on the graph of f(x), find
the corresponding point for the function
f(x - 5).
Answer:
(-1, -6)
Step-by-step explanation:
f(x -5) is another way to say f(x) - 5
And f(x) - 5 is going down the y axis 5 points, so you end at (-1, -6)

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98
=65.41

What single percentage change is equivalent to a 12% decrease followed by a 18% increase?
Given:
12% decrease followed by a 18% increase.
To find:
The single percentage change is equivalent to the given set of percentages.
Solution:
Let the initial value be 100.
After 12% decrease, the value is:
[tex]v_1=100-\dfrac{12}{100}\times 100[/tex]
[tex]v_1=100-12[/tex]
[tex]v_1=88[/tex]
After 18% increase, the value is:
[tex]v_2=88+\dfrac{18}{100}\times 88[/tex]
[tex]v_2=88+15.84[/tex]
[tex]v_2=103.84[/tex]
The initial value is 100 and the new value in 103.84. So, it represents increase in the value. So, increase percentage is
[tex]Increase\%=\dfrac{\text{New -Initial}}{\text{Initial}}\times 100[/tex]
[tex]Increase\%=\dfrac{103.84-100}{100}\times 100[/tex]
[tex]Increase\%=3.84[/tex]
Therefore, the value increased by 3.84%.

Dennis got 85 percent of the questions on the math test correct, which was out of 40. what was his actual mark?
Answer:
34/40
Step-by-step explanation:
85/100 cross multiply x/40
100x/100=3400/100
x=3400/100
3400/100=34
x=34

¿Cuál es el valor de x en la siguiente ecuación?
4X =8 -8
12, 17, 22... find the 35th term
Answer:
a₃₅ = 182
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 12 = 22 - 17 = 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 5 , then
a₃₅ = 12 + (34 × 5) = 12 + 170 = 182
2. Write two numbers that are opposites and each more than 6 units away from 0.
Answer:
-7, 7
Step-by-step explanation:
Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)
Find all solutions to the equation.
cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
