Step-by-step explanation:
8+4y= -8
4y= -8 -8
4y= -16
divide both sides by the coeffient of the variable. in this case divide both sides by 4
y=-4
Answer:
y = -4
Step-by-step explanation:
8+4y= -8
4y = -8 -8
4y = -16
y = (-16) ÷ 4

A. y = 4x - 28
B. y = - 4x + 28
OC. y= 3x-28
OD. y=x+28
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table
m = [tex]\frac{28-29}{0+4}[/tex] = - [tex]\frac{1}{4}[/tex]
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
y = - [tex]\frac{1}{4}[/tex] x + 28 ← equation of line → D
combining like terms with negative coefficients

Solve the literal equation cy−7=5d+3y for y.
y=
Answer: y = 5d + 7 / c - 3
Step-by-step explanation:
Step 1: Add -3y to both sides
cy - 7 + -3y = 5d + 3y + -3y
= cy - 3y - 7 = 5d
Step 2: Now, add 7 on both sides
cy - 3y - 7 +7 = 5d +7
= cy - 3y = 5d +7
Step 3: Factor out y
y(c - 3) = 5d + 7
Step 4: Divide both sides by c-3
y(c - 3) / c - 3 = 5d+7 / c-3
Your answer for this should be
y = 5d + 7 / c - 3

Answer:
100
Step-by-step explanation:
cause they its 100
Answer:
14 feet
Step-by-step explanation:
Use the square area formula, A = s², where s is the side length
Plug in the area and solve for s:
A = s²
200 = s²
14 = s
So, each side of the patio is 14 feet

Which expression is equivalent to pq ?
P + q
P - q
P/q
qp
Answer:
qp
Step-by-step explanation:
pq = p * q
In multiplication like this, the order doesn't matter:
5 * 3 = 15
3 * 5 = 15
2 * 9 = 18
9 * 2 = 18
Thus,
pq = p * q = q * p = qp
Answer: qp

What is Equation of a line?The equation of a straight line is y=mx+c y = m x + c m is the gradient and c is the height at which the line crosses the y -axis, also known as the y -intercept.
here, we have,
By observation, the graphed line crosses the y-axis at point; (0, 3). Hence, the y-intercept is at y= 3.
Additionally, the slope of the line can be evaluated by considering the two points given;
Slope, m = (2-3)/(3-0)
Slope, m = -1/3
Hence, the equation of the line is;
y = (-1/3)x + 3

4) How many km in
58,795cm?
Please help thanks!!
Step-by-step explanation:
1 km is equal to 100,000 cm.
58,795 is close to 50,000, which is half of 100,000. So our estimate would be 1/2 km to 50,000 cm.
Convert 58,795 to a decimal.
0.58795
The decimal cannot be simplified so there is
0.58795 km in 58,795 cm

Owen’s parents were planning a birthday party for him. They have $20.00 to spend on goodie bags. They need to buy 6 goodie bags at $2.49 each. Will Owen’s parents have enough money to buy all 6 goodie bags? I HAVE TO SHOW MY WORK
Answer:
Yes, they can buy all the bags.
Step-by-step explanation:
Owen's parents need to buy 6 bags for $2.49 each.
So, we need to calculate the total price:
$2.49 * 6 = $14.94
Since the bags cost $14.94, and Owen's parents have $20.00, they have enough money to buy all 6 bags. 14.94 < 20.00
Hope this helps!
Answer:
They will have enough money to spend on 6 goodie bags
Step-by-step explanation:
First, you need to mutiply $2.49 × 6 and then you get 14.94
then you need to subtract $20.00 - 14.94 to get $5.06
so your answer should be, ¨Owen´s parents will have $5.06 left after spending $14.94 of their $20.00 on goodie bags¨

The table shows the maximum and minimum depths of two submarines. Find the range of depths for each submarine. Then determine which submarine has the greater range of depths.
Submarine A Submarine B
Minimum Depth −146 ft −194 ft
Maximum Depth −532 ft −621 ft
Answer:
Range A = 386ft
Range B = 427ft
B has the larger range.
Explanation:
To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.
Sub A:
-146ft - (-532ft) = 386 ft
Sub B:
-194ft - (-621ft) = 427 ft
Submarine B has a larger range.

The correlation coefficient r between an employee’s age, x, and yearly salary, y, is 0.633. What percent of the variation in yearly salaries can be explained by differences in the employees’ ages? 31.7% 63.3% 15.8% 40.1%
Answer:
The answer is 40.1%
Step-by-step explanation:
I just took the test
The variation in the yearly salaries can be explained by the differences in employee ages up to 40.1%.
When given the correlation coefficient of two variables, you can find out how much of the variation in the dependent variable can be explained by the independent variable by the formula:
= (Correlation coefficient)² x 100%
= 0.633² x 100%
= 0.4007 x 100%
= 40.1%
In conclusion, 40.1% of the variation in salary can be explained by age.

|4x + 4| = 15
First, let's get rid of the absolute value signs to get the first solution.
4x + 4 = 15
Subtract 4 from both sides
4x = 11
Divide each side by 4
x = 11/4 or 2.75
Now, let's get the solution by changing 15 to -15.
4x + 4 = -15
Subtract 4 from both sides
4x = -19
Divide both sides by 4
x = -19/4 or -4.75
