g(x)=-7x+4 solve for (-5)
Answer:
39
Step-by-step explanation:
g(-5)=-7×(-5)+4=35+4=39
Answer:
g(-5) = 39
Step-by-step explanation:
g(x) = -7x + 4
g(-5) = - 7* (-5) + 4
= 35 + 4
= 39

Write the equation of the line whose slope and the point through which it passes are given. Express
the equation in point-slope form.
(4,0) and slope m=-7
Answer:
[tex]y-0=-7(x-4)[/tex]
Step-by-step explanation:
Equation of a line
The point-slope form of the equation of a line is:
[tex]y-k=m(x-h)[/tex]
Where m is the slope and (h,k) is a point through which the line passes.
The line passes through the point (4,0) and has a slope of -7. The equation of the line is:
[tex]y-0=-7(x-4)[/tex]
This is the point-slope form of the line.

Solving equations with Fractions?
Answer:
basically just multiply the fractions by a common number until you have whole numbers, then solve like normal
Step-by-step explanation:
help please i don’t know which one it is
Answer:
D
Step-by-step explanation:
The formula matches up with the sequence. If you want to find f2 you look to f1 which is 8. Then you subtract by 2. This means to get f1, f0 would have to be 10 because 10-2 is 8.

What is the greatest common factor of 45, 50, 84?
Answer:
the greatest common factor is B - 1
Step-by-step explanation:
not 5 because 85 doesn't end with 0 or 5
not 3 because 5+0 doesn't equal a multiple of 3
not 2 because 45 is odd
not 0 because that's never an answer

Lin rode her bike 2 miles in 8 minutes. How many miles did she go in 4
minutes?
Answer:
1 mile: 4 minutes
Step-by-step explanation:
This problem can be expressed with a simple ratio: 2:8
Now, thankfully the numbers are even so we just need to simplify the ratio to get our answer. Ratios work like fractions in that manner. So we just need to divide both sides by 2 to get the _:4 result.
This gives us a ratio of 1:4. Therefore, Lin travelled 1 mile in 4 minutes.
Ally works in a shop for 18$ per hour. She is not allowed to work more than 40 hours a week but has to work atleast 20 hours. State a reasonable domain for this problem
Answer:
Hi there!
The domain is:
20<=x<=40
Step-by-step explanation:
18$ per hour
x is hours worked
The domain is:
20<=x<=40
This says that:
x=>20
x<=40
Which fits the problem!

A garden table and a bench cost $600 combined.
The cost of the garden table is three times the cost of the bench.
What is the cost of the bench?
Answer:
$150
Step-by-step explanation:
A garden table and a bench together will cost $600. The actual values of the garden table and the bend are not given, but we know that the cost of a garden table will cost three times more than the bench.
Let [tex]x[/tex] = the cost of the bench.
Again, since the cost of the garden table is three times the cost of the bench ([tex]x[/tex]), we can represent the garden table as three times [tex]x[/tex] ([tex]3x[/tex]). These two terms will equal $600 when added, so let's formulate an equation:
[tex]3x+x=600[/tex]
Combine like terms:
[tex]4x=600[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]4[/tex]:
[tex]x=150[/tex]
_
Check your work by substituting [tex]150[/tex] into the original equation:
[tex]3(150)+(150)=600[/tex]
[tex]450+150=600[/tex]
[tex]600=600[/tex]
Our answer is correct!

A square window has an area of x2 + 22x + 121 square feet. Find the length of one side of the square.
A) (x + 11) feet
B) (x – 11) feet
C) (x – 6) feet
D) (x + 6) feet
x + 11 ft
Step-by-step explanation:
x² + 22x + 121 ft² = area of square
x² + 11x + 11x + 121 ft² = side²
x(x + 11) + 11(x + 11) ft² = side²
(x + 11)(x + 11) ft² = side²
(x + 11)² ft² = side²
x + 11 ft = side²
What is the slope of a line which passes through the points (-6, 4) and (4, 6)?
A) 5
B)1/5
C)2
D)1/2
Answer:
1/5
Step-by-step explanation:
To find the slope between two points, we use the formula
m = ( y2-y1)/(x2-x1)
= ( 6-4)/(4 - -6)
= ( 6-4)/(4+6)
= 2/10
= 1/5
w=r-47/-4

Answer:
r=-15/4
Step-by-step explanation:
Pleaseee helppppp 3-6
Step-by-step explanation:
Here is Slope-Intercept Form for a line: y=mx+b
m is the slope
b is the y intercept
The y intercept is basically the point on the y axis where the line touches.
I will do #3 for you.
Let's first look for the y intercept. We can see that the line touches the y axis at -4, so that's it.
Let's put it into our equation, plugging in -4 for b. This is what we have so far: y=mx-4
To complete this equation, we still need to find the slope, m.
To find it, look at the point where the y intercept is, and count how many units you need to go up or down the y axis, and then right or left the x axis to get to another point on the line. The slope is equal to the change in y ÷ the change in x.
So we see that there's another point on (-3, -2), so let's try to get there from the y intercept.
We need to move two units up and 3 to the left.
In terms of y, we went up +2, and in terms of x, we went down -3
So our slope is 2/-3 or -2/3.
Now that we have our slope (m) and y intercept (b), we can plug it into out Slope-Intercept Equation, plugging in -2/3 for m:
y=-2/3x-4.
We don't need to find x or y. This is our answer for 3. Using the same method, you should be able to find the equations for the rest of the graphs. Good luck.
