8x-2=-947x
What does X stand for ?
Answer:
-7
Step-by-step explanation:
1st, regroup terms.
8x-2 = 7x -9
Next, subtract 7x from both sides.
8x-2-7x = -9
Next, Simplify 8x-2-7, to -2.
x-2 = -9
Add 2 to both sides.
x = -9 + 2
Simplify −9+2 to −7.

Answer:
1/8
Step-by-step explanation:
3/4 can be rewritten as 6/8 to make this easier.
-5/8 + 6/8 is like doing -5 + 6, giving you 1. We can then reintroduce the denominator to get the answer of 1/8.

Write an equation in point-slope form. Crossing the x-axis at x = -3 and the y-axis at y = 6
Answer:
y = 2x + 6
Step-by-step explanation:
The equation for a linear line is y = mx + c.
We know we want it to cross the y-axis at 6, so the y-intercept (c) can be assumed to be 6.
If we substitute in the x that we want, we end up with this:
0 = m(-3) + 6
m = 2
So now we can form the equation:
y = 2x + 6
y = x - 7, when x = 12.5
Hey there! Welcome to Brainly! I'm happy to help!
Let's plug this value of x into our equation.
y=12.5-7
y=5.5.
Have a wonderful day! :D
Steps to solve:
y = x - 7 when x = 12.5
~Substitute
y = 12.5 - 7
~Subtract
y = 5.5

x2 − 11x = −30
x2 − 11x = 30
x2 + 11x + 30 = 0
x2 + 11x = 30
Answer:
x2 - 11x = -30
Step-by-step explanation:
x^2 - 11x = -30
add 30 to the left to make it = to zero
x^2 - 11x + 30 = 0

(x-5)(x-6) = 0
check by FOIL
x times x = x^2
x times -6 = -6x
x times -5 = -5x
-6 + -5 = 11x

Find the area of the region bounded by the graphs of the equations. y = −x2 + 4x, y = 0
Answer:
Area = 32/3
Step-by-step explanation:
To find the area bounded by the graphs, we will
need to first equate the y values;
-x^2 + 4x = 0
x^2 = 4x
divide both sides by x
x = 4
So the area we want to calculate now is the integral of -x^2 + 4x from 0 to 4

Write y+1=-2x-3 in standard form
Answer:
y=2x-4
Step-by-step explanation: this looks alot like an equation for slope is it?
Answer:
-2x - y = 4
Step-by-step explanation:
Standard Form: Ax + By = k
Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:
y + 1 = -2x - 3
y (-y) + 1 = -2x - 3 (-y)
1 = -2x - 3 - y
1 = -2x - 3 - y
1 (+3) = -2x - 3 (+3) - y
4 = -2x - y
Set the equation so that it looks like the standard form equation given above:
-2x - y = 4 is your answer.

I’m so confused someone help please! (Geometry)
Answer:
Therefore, x = 23°, ∠LKM = 56° and ∠MKN = 89° .
Step-by-step explanation:
Given that ∠LKN is 145° so we can assume that ∠LKM addes together with ∠MKN will get 145° in terms of x :
[tex]∠lkn = ∠lkm + ∠mkn = 145[/tex]
[tex]2x + 10 + 4x - 3 = 145[/tex]
[tex]6x + 7 = 145[/tex]
[tex]6x = 145 - 7[/tex]
[tex]6x = 138[/tex]
[tex]x = 138 \div 6 = 23[/tex]
Next, we have to substitute x = 23° into the expressions of ∠LKM and ∠MKN :
[tex]∠lkm = 2(23) + 10 = 56[/tex]
[tex]∠mkn = 4(23) - 3 = 89[/tex]

It takes a thermal drill 13 minutes to bore a hole -39 feet from ground level into a glacier. What is the change in depth after one minute?
Answer:
3 feet
Step-by-step explanation:
39 divided by 13 = the unit rate per min.
39 divided by 13 = 3
Answer:
-3 feet
Step-by-step explanation:
Divide -39 by 13, since it takes 13 minutes to dig -39 feet:
-39/13
= -3
So, the change in depth after one minute is -3 feet

#4. Identify the conclusion of the conditional statement: "I must reset the
clock if it's Daylight Saving time."*
A- I must reset the clock
B-It's Daylight Saving time
C-There is not conclusion
Answer:
C-There is not conclusion
Step-by-step explanation:
In a conditional statement, there is a hypothesis and a conclusion. It is usually symbolized or represented by " If X, then Y." It is an if - then statement.
Here, the statement "X" is called the hypothesis and the statement "Y" denotes the conclusion. The conclusion is true if the hypothesis is true.
The conclusion of any conditional statement is the immediate phrase that follows the word 'then'.
In the context, the sentence "I must reset the clock if it's Daylight Saving time." , the word 'then' is not there, so we can say that there is no conclusion in the statement.
