Answer:
7/8
Step-by-step explanation:
rate of change = slope
8y = 7x+56
divide both sides by 8: y = 7/8x+7
rate of change = 7/8
Simplify: (-2x)⁴

Answer: 16x^4
Step-by-step explanation: Because -2 4 times is 16 and x is unknow.
The value of the expression [tex](-2x)^4[/tex] is -16[tex]x^4[/tex].
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
[tex](-2x)^4[/tex]
This can be written as,
[tex](-2)^4[/tex] x [tex](x)^4[/tex]
16[tex]x^4[/tex]
Thus,

3/4 + 3/9 how do i do this
Answer:
13/12
Step-by-step explanation:
Well, you can't add it yet because the denominators don't match. We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change as well. So, multiply 3 by 8, and get 24. Since 4 is evenly divided by 8, we can multiply just one term to get a common denominator. Multiply 3 by 2, and get 6, then we multiply 4 by 2 and get 8. Since our denominators match, we can add the numerators. So now your answer should be 9/8. Well guess what... IT IS THE ANSWER! You can't reduce it anymore so 9/8 is your answer! Hope this helped!

Answer:
The result in standard form is: [tex]2.3 \times 10^{6}[/tex]

Dividing the values:
To find the real part, we divide 2.645 by 1.15. So
2.645/1.15 = 2.3
Finding the power:
Its a division, so we keep the base, and subtract the exponents. So

Find the vertex of the graph of the quadratic function and determine whether it's an absolute maximum or an absolute minimum: y=-2x- 8x - 16.
A. Vertex: (-2,-8); minimum
B. Vertex: (-8,-2); maximum
C. Vertex: (-8,-2); minimum
D. Vertex: (-2,-8); maximum
Answer:
A
Step-by-step explanation:
Because the leading coefficient of this function is negative, we can rule out answers with the vertex as the minimum. using -b/2a, we get -2 which leaves us with A as our answer.

How many meals would be packed in 20 hours?
Given :
A graph of Total Meals Packed vs Time( in hours ).
To Find :
How many meals would be packed in 20 hours.
Solution :
First we will find the equation of line.
Now, the line passes through ( 0, 0 ) and ( 4, 500 ).
So, equation of line passing through ( 0, 0 ) and ( 4, 500 ) is :
[tex]y - 0 = \dfrac{500-0}{4-0}( x - 0 )\\\\y = 125x[/tex]
Now, putting the value of x = 20 hours in above equation, we get :
y = 125 × 20 meals
y = 2500 meals
Therefore, number of meals packed in 20 hours is 2500 meals.

Find the value of y and type your result in the empty box.
Answer:
y=37
Step-by-step explanation:
the addition of the 3 angles is 180°
then 40 + y +29 +2y = 180

3y = 180 -69
3y= 111
y =111 ÷ 3
y = 37
Lucy plants 29 flowers in 2 hours
part A assuming Lucy plants flowers at a constant rate, which equation represents the number of flowers, y, lucy can plant in x hours?
A. y=2/29x
B. y=2x+29
C. y=29x+2
D. y= 29/2x
D. y = 29x / 2
What is a linear equation?Every variable in a linear equation has an exponent of 1, or in other words, every variable is expressed with zero exponents.
Given Lucy plants 29 flowers in 2 hours. assuming Lucy plants flowers at a constant rate, let the number of flowers, y, lucy can plant in x hours.
29 Flowers in 2 hours
29 = 2
∴ 1 = 29/ 2 (flower planted in one hour)
Flower planted in x hour
x = 29x / 2
Given in x hour lucy planted y flower.
Therefore, y = 29x / 2 is an equation that represents how many flowers lucy plants in x hours.

After a 80% reduction, you purchase a new washing machine on sale for $152. What was the original price of the washing machine?
Answer:
760$
Step-by-step explanation:
Alright so, we know that there is 80% reduction. But to find the exact percentage reduction for the sale price we know that we have to take the total subtract with the given percentage.
That is
100%- 80%= 20%
Then
20%=152$
1%=152/20
100%=152/20×100= 760 $
Hopefully it helps☆
The original price of the washing machine before the reduction is $760 .
Given,
we know that there is 80% reduction.
Now,
But to find the exact percentage reduction for the sale price we know that we have to take the total subtract with the given percentage.
That is
100%- 80%= 20%
Then
20%=$152
1%=152/20
1% = $7.6
So if 1% is equals $7.6 .
Then 100%
100%=152/20×100= $760
Thus the original price of the article is $760 .
