What is an equation of the line that passes through the point (−2,−2) and is parallel to the line 5x−y=4?
Answers
Answer:
It is -5
Step-by-step explanation:
Answer: y=5x+8
Step-by-step explanation:
first you solve for y:
5x - y = 4
-5x -5x
↓
[tex]\frac{-y}{-1}[/tex] = [tex]\frac{-5x+4}{-1}[/tex]
↓
y = 5x - 4
slope of given line: 5
slope of a parallel line: 5
plug in slope:
y = 5x + b
find b, which is 8 :)
plug it in!
y = 5x + 8

8 cubed in standard form and exponential form
Answers
Answer:
so 8 cubed (8 × 8 × 8) in standard form is: 512so 8 cubed (8 × 8 × 8) in exponential form is: 8³Step-by-step explanation:
As we know that
The cube of any given number is that number times itself.
For example, 8 cubed, denoted by 8³ is equal to 8 × 8 × 8.
An exponent basically indicates the number of times we must multiply the base number. For example, to compute 8³, we multiply 3 three times (8×8×8).
so 8 cubed (8 × 8 × 8) in standard form is: 512so 8 cubed (8 × 8 × 8) in exponential form is: 8³Help plz with this math problem. I’m so confused

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.
From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).
The equation to find the slope is:
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's substitute in our values:
m = [tex]\frac{-2 - -4}{6 - 3}[/tex]
Remember that two negatives make a positive, let's solve for m:
m = [tex]\frac{2}{3}[/tex]
Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).
Therefore we can determine that b = -6.
Let's substitute our value for m and our value for b into the slope-intercept formula:
y = mx + b
y = [tex]\frac{2}{3}[/tex]x + -6
There's your final answer! I hope this helps, have a great night. :)

Several paint mixtures are made by mixing blue paint and white paint. Paint Colors Blue Paint White Paint Mixture A 5 cups 12 cups Mixture B 6 cups 6 cups Mixture C 4 cups 12 cups Mixture D 5 cups 6 cups Which mixture has the lowest ratio of blue paint to white paint? mixture A mixture B mixture C mixture D
Answers
Answer:
The mixture C is the correct option
Step-by-step explanation:
According to the given scenario, the calculation is as follows:
For Mixture A
Blue Paint - 5 cups
White Paint - 12 cups
The ratio between them is 5:12
For Mixture B
Blue Paint - 6 cups
White Paint - 6 cups
The ratio between them is 6:6 = 12:12
It came by multiply the numerator and denominator by 12
For Mixture C
Blue Paint - 4 cups
White Paint - 12 cups
The ratio between them is 4:12
For Mixture D
Blue Paint - 5 cups
White Paint - 6 cups
The ratio between them is 5:6 = 10:12
It came by multiply the numerator and denominator by 12
As it can be seen that in all four mixtures the denominator is the same so for calculating the lowest ratio we have to see the small value in the numerator
As it can be seen that there is a small value of 4
hence, the mixture C is the correct option
Answer:
C mixture

Which are the values equivalent to the given expression?Here we start with the expression:
(9.6*10³)*(6.7*10)
Where both numbers are in scientific notation, notice that we can write that product as:
(9.6*10³)*(6.7*10) = (9.6*6.7)*(10³*10) = 64.32*10⁴
Now, remember that in scientific notation, we only can have a single digit in the left of the decimal point, so we can rewrite:
64.32*10⁴ = 6.432*10⁵
So the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.

Multiply x on both sides: xtan55° = 19Divide tan55° on both sides: x = 19/tan55°Evaluate: x = 13.3039Round: x ≈ 13.3And we have our final answer!
Answer:
13.3
Step-by-step explanation:
This is trigonometry
So for this one, we use a basic ratio. We need to use 19 and 55 degrees for the answer. We are given that the leg adjacent to the 55-degree angle is x and the opposite leg to the 55-degree angle is 19.
So we use tangent(opposite leg/adjacent leg) for this (TOA of SOH CAH TOA)
tan(55 degrees)=19/x
SO then solve for x and then evaluate using a scientific calculator and you should get 13.30394322
