Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.
Combine like terms.
6h + C + 3f + 2f + 2h
Do not use any spaces in your answers.
Answer:
Step-by-step explanation:
Imagine h = hedgehog
C = cat
f = ferret
6h + C + 3f + 2f + 2h is like saying
6hedgehogs + cat + 3ferrets + 2ferrets + 2 hedgehogs =?
You can only combine the things that are the same.
This means you get 8 hedgehogs + cat + 5 ferrets.
In other words,
8h + 5f + C
Show work, and find the product.
−4x5(11x3+2x2+9x+1)
Answer:
-44x⁸–8x⁷–36x⁶–4x⁵
Step-by-step explanation:
when you expand problems like these you need to multiple the number in front of the variable the the other numbers in front of the variables and add the exponentslike this-4•11= -44 | 5+3=8 I -44x⁸-4•2= -8 | 2+5=7 | -8x⁷-4•9= -36 | 1+5=6 | -36x⁶-4•1= -4 | 0+5=5 | -4x⁵put it all together and you get -44x⁸–8x⁷–36x⁶–4x⁵if my explanation is confusing I'm sorry feel free to ask questions

What is the y-intercept of the line 3x – 7y = 42?
Answer:
(0, -6)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Write standard form
3x - 7y = 42
Step 2: Rewrite in slope-intercept form
Subtract 3x on both sides: -7y = 42 - 3xDivide both sides by -7: y = -6 + 3/7xRewrite: y = 3/7x - 6Step 3: Find y-intercept
b = -6
Answer:
(0, -6)

Answer:
p=9 m=21 x= - 30
Step-by-step explanation:
p=9
m=21
x= - 30
Step-by-step explanation:
1) 3p + 5 = 14
3p = 14 - 5
3p = 9
p = 9/3
⇢ p = 3
2)
m/7 - 3 = 0
m/7 = 3
m = 3 × 7
⇢ m = 21
3) 8 + x/2 = -7
x/2 = -7 - 8
x/2 = - 15
⇢ x = -30

Which of the following does not represent a function? (1 point)
Answer this as quick as possible
Answer:
The oval
Step-by-step explanation: A function must pass the vertical line test.
Answer:
The third one (oval)
Step-by-step explanation:
To see if something is a function or not, you do the vertical line test. So just draw lines vertically over the x-values. If an x-value has more than one y-value then it is not a function. It is a relation.
Im trying to plot a slope function on a graph
Answer:
Graphing from slope
Step-by-step explanation:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.
Which of these equations has a negative sloping line?*
O y=-2/3x +8
O y = 2/3x - 8
O y = 4/3x +10
O y = 9/5x - 3
Answer:
Option 1.
Step-by-step explanation:
That option is the only one with a negative x coefficient, which is the slope.
Answer:
y=-2/3x +8
Step-by-step explanation:
the coefficient of x determines the slope of the line so negative coefficient, negative slope line

the measure of the 2 angles =45 degrees each
2) Ruth borrows $440 at 0.6% simple interest per month. When
Ruth pays the loan back 4 years later, how much interest does
Ruth pay?
Answer:
$10.56
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 0.6%/100 = 0.006 per year,
then, solving our equation
I = 440 × 0.006 × 4 = 10.56
I = $ 10.56
The simple interest accumulated
on a principal of $ 440.00
at a rate of 0.6% per year
for 4 years is $ 10.56.
Answer:
450.56
Step-by-step
440 x 0.006 x 4 + 440 =450.56

(4v³w)(-2w³)² in simplest form
Answer:
16 v^3 w^7
Step-by-step explanation:
Simplify the following:
4 v^3 w (-2 w^3)^2
Hint: | Distribute exponents over products in (-2 w^3)^2.
Multiply each exponent in -2 w^3 by 2:
4 v^3 w×(-2)^2 w^(2×3)
Hint: | Multiply 2 and 3 together.
2×3 = 6:
4×(-2)^2 v^3 w w^6
Hint: | Evaluate (-2)^2.
(-2)^2 = 4:
4×4 v^3 w w^6
Hint: | Combine products of like terms.
4 v^3 w×4 w^6 = 4×4 v^3 w^(1 + 6):
4×4 v^3 w^(1 + 6)
Hint: | Evaluate 1 + 6.
1 + 6 = 7:
4×4 v^3 w^7
Hint: | Multiply 4 and 4 together.
4×4 = 16:
Answer: 16 v^3 w^7

Find the missing side in the similar figure below
Answer:
30
Step-by-step explanation:
20 divided by 12 is 5/3.
18x5/3 is 30, meaning the missing side is 30.
The value of x from the diagram is 30
Similar shapesThese are shapes with the same sides and angles
From the given figures, we are to get the value of x as shown.
Using the similarity theorem;
18/12 = x/20Cross multiply
12x = 18 * 20
12x = 360
x = 30
Hence the value of x from the diagram is 30
