What is the slope-intercept equation of the line whose y-intercept is
8 with slope -5?
Answer:
y = - 5x + 8
Step-by-step explanation:
Given that :
Intercept = 8
Slope = - 5
Recall, the general. Slope - intercept equation :
y = bx + c
Where;
b = slope ; c = intercept
Plugging the Given slope and intercept values, equation becomes ;
y = - 5x + 8

Step-by-step explanation:
Зу + 9x = 12
y=mx+b
Answer:
y = -3x + 4
Step-by-step explanation:
3y + 9x = 12
subtract 9x
3y = 12 - 9x
divide by 3 on both sides
y = 4 - 3x
or
y = -3x + 4
Answer:
y=-3x + 4
Step-by-step explanation:
Convert standard form equation into y-intercept form
3y +9x=12
3y= 12-9x
Divide both sides by 3 to isolate the y (you can flip the equation if it is easier)
y= -3x+4
hope this helps and have a great day :)
A bread recipe calls for 1/4 tsp of salt. How much salt is needed to make 6 loaves of bread?
Answer:
1 1/2 tsp
Step-by-step explanation:
2x + 7 = 19
X=?
Which one is the answer
Answer:
x=6
Step-by-step explanation:
first you subtract 7 and 7 and you also have to subtract 7 and 19 and the answer will be 12 then you divide 2 and 2 to make it only x so if you divide 2 and 2 you also have to divide the 12 so 12 divided by 2 equal 6 so the x is equal to 6

Answer:
| - 16 |
Step-by-step explanation:
The absolute value function always gives a positive value, that is
| - a | = | a | = a
Then
| 6 | = 6
| - 16 | = | 16 | = 16
Thus the largest number from the list is | - 16 |

Answer:
4 hours
Step-by-step explanation:
120-72=48
48÷12=4
Answer:
4
Step-by-step explanation:
The total amount was $120.
A portion of the $120 was for parts.
The rest of the $120 was for service. Service cost $12 per hour.
Start with $120.
Subtract $72 to find the amount spent on service.
$120 - $72 = $48
$48 was spent on service.
The service costs $12 per hour.
$48/($12/hour) = 4 hours
Answer: 4 hours
Check:
$72 in parts + 4 hours * $12/hour = $72 + $48 = $120
4 hours is correct.
How many times greater is the area circle 1( radius 12) of than the area circle 2( radius 4) of ?
Answer:
The area of circle 1 is 9 times greater than area of circle 2.
Step-by-step explanation:
Given that:
Radius of circle 1 = 12
Area of circle 1 = πr²
Area of circle 1 = [tex]3.14*(12)^2 = 3.14*144[/tex]
Area of circle 1 = 452.16
Radius of circle 2 = 4
Area of circle 2 = [tex]3.14*(4)^2 = 3.14*16[/tex]
Area of circle 2 = 50.24
Let,
x be the number of times circle 1 is bigger than circle 2.
Area circle 1 = x * Area circle 2
[tex]\frac{452.16}{50.24}=\frac{50.24x}{50.24}\\\\x=9[/tex]
Hence,
The area of circle 1 is 9 times greater than area of circle 2.

Are the ratios 1:2 and 7:20 equivalent?
Answer:no
Step-by-step explanation:
Two cars are heading toward the same intersection. Car A travels due east at 20 miles per hour, and Car B travels due north at 50 miles per hour. At what rate, in miles per hour, is the distance between the two cars decreasing when Car A is 0.375 miles from the intersection and Car B is 0.5 miles from the intersection?
Answer:
the distance between them is decreasing at a rate of 2 mph.
Step-by-step explanation:
List all given rates and the unknown rate.
Write the formula that relates the variables in the problem: x, y, and s.
There’s a right triangle in the diagram, so you use the Pythagorean Theorem:
For this problem, x and y are the legs of the right triangle, and s is the hypotenuse, so
Differentiate with respect to t.
Use the Pythagorean Theorem again to solve for s.
x = 0.4
y = 0.3
You can reject the negative answer because s obviously has a positive length. So s = 0.5.
Now you’ve got everything you need to substitute into the differentiation result and solve for ds/dt.
This negative answer means that the distance, s, is decreasing. Thus, when car A is 3 blocks north of the intersection and car B is 4 blocks east of the intersection, the distance between them is decreasing at a rate of 2 mph.

Why did most ancient cultures writ out their mathematical texts in words
Answer:
They had no numeral for zero in their number system.
Without a zero, it is hard to accurately represent real world problems. This makes it easier to use words rather than numbers.

Which equation can be used to find the missing angle?
a. X + 90 = 180
b. X + 40 = 90
c. 180 - 40 = x
Answer:
A, all three angles of a triangle equal 180
Answer:
b. x + 40 = 90
Step-by-step explanation:
This is a right triangle, so we already know one of the angles is 90 degrees. The other angles combine to make the other 90 degrees. So, we have to figure out what the other angle is, as the second one is 40 degrees. To figure that out, use the equation x + 40 = 90. (This is extra, but x is 50, right?)

Paul has $145 in his savings account. He earns $36 a week mowing lawns. If Paul saves all of his earnings, after how many weeks will he have no more than $450 saved?
Answer:
Paul will have no more than $ 450 in next 8 weeks.
Step-by-step explanation:
From the information given on statement, we know that Paul saves all of his earnings weekly. Then, the money save is equal to the sum of initial amount ([tex]C_{o}[/tex]), measured in monetary units, and week earning ([tex]R[/tex]), measured in monetary units, multiplied by a number of weeks ([tex]n[/tex]), dimensionless:
[tex]C =C_{o} + n\cdot R[/tex] (1)
Now we clear the number of weeks within the formula:
[tex]n = \frac{C-C_{o}}{R}[/tex]
If we know that [tex]C_{o} = \$\,145[/tex], [tex]C = \$\,450[/tex] and [tex]R = \$\,36[/tex], then the number of weeks is:
[tex]n = \frac{\$\,450-\$\,145}{\$\,36}[/tex]
[tex]n = 8.472[/tex]
Paul will have no more than $ 450 in next 8 weeks.
Answer:
Paul will have no more than $ 450 in next 8 weeks.

Answer:
5.23 × 10 ^7
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
