U said solve for x do u mean z?
z=-4
Answer: z = -4
Step-by-step explanation:
Simplifying
5z + -8 = -28
Reorder the terms:
-8 + 5z = -28
Solving
-8 + 5z = -28
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + 5z = -28 + 8
Combine like terms: -8 + 8 = 0
0 + 5z = -28 + 8
5z = -28 + 8
Combine like terms: -28 + 8 = -20
5z = -20
Divide each side by '5'.
z = -4
Simplifying
z = -4 Hope this helps !

what is the answer when you simplify?.
Answer:
C
Step-by-step explanation:
Because when you multiply 4³ × 4^4 = 16384
And 4^9 = 262144
(divide) 16384/262144 = .0625
.0625 = [tex]\frac{1}{16}[/tex]
[tex]\frac{1}{4^2}[/tex] = [tex]\frac{1}{16}[/tex]
because 4 * 4 = 16

29.8 is 10 times as much as what
Answer:
298
Step-by-step explanation:
29.8 is 10 times as much as 298
The required proportion value is 2.98 which is equal to one-tenth of 29.8.
Given that,
To determine 29.8 is 10 times as much as a number.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number be x,
According to the question.
29.8 = x10
x = 29.8 / 10x
x = 2.98
Thus, the required proportion value is 2.98 which is equal to one-tenth of 29.8.

The predicted calories in food items based on grams of fat are represented by the residual plot.
What does the pattern in the residual plot indicate about the type of model?
A. The pattern is random, indicating a good fit for a nonlinear model.
B. The pattern shows the points are far from the zero line, indicating a good fit for a linear model.
C. The pattern is random, indicating a good fit for a linear model.
D. The pattern shows the points are far from the zero line, indicating a good fit for a nonlinear model.
E. The pattern is random, indicating that the model is unable to be determined.
Answer:
The correct option is;
C. The pattern is random, indicating a good fit for a linear model
Step-by-step explanation:
A graph that has the residuals (the difference between the value observed and the value expected (regression analysis) on the vertical axis and the variable that is not affected by the other variables (independent variable) on the x or horizontal axis is known as a residual plot
A linear regression model is suited in a situation where the points are dispersed randomly on both sides of the horizontal axis
Therefore, given that the first point is below the horizontal axis and the next point is above the horizontal axis, while the third and the fourth points are below the horizontal axis, the fifth, sixth, and seventh points are above the horizontal axis and the eighth point is below the horizontal axis, the points are random around the horizontal axis, indicating the suitability of a linear regression model.
Answer:
C. The pattern is random, indicating a good fit for a linear model.

Complex roots always occur as conjugate pairs , thus
x = - 2 + [tex]\sqrt{8}[/tex] is a root then x = - 2 - [tex]\sqrt{8}[/tex] is a root

how do you write y-2=-1/3(x-7)
Answer:
y= -1/3 + 13/3
Step-by-step explanation:
y-2=-1/3(x-7)
Use the distributive property to simplify the right side of the equation
y-2=(-1/3 * x) + (-1/3 * -7)
y-2=-1/3x + 7/3
Add 2 to both sides get the y by itself. 2 can be expressed as 6/3
(y-2) + 2=(-1/3x + 7/3) + 6/3
y= -1/3x + 13/3

Answer:
The domain is continuous and the weight y of x identical hardcover books
Step-by-step explanation:
Discrete means non continuous data. This is continuous and equal so the domain is continuous.
Also, precipitation each week can vary so that won't work. Eating carrots each day can also vary so that doesn't work. The cost of an item can vary almost every day! So that is not true.
Therefore it is the last one, because it is identical and all of the coordinates make (1,3).

Draw the image of ABC under dilation whose center is P and scale factor is 4.
Answer:
By plotting points A', B' and C' we can get the dilated image A'B'C'.
Step-by-step explanation:
Let the point P is origin (0, 0), segment AB lies on the x-axis and segment PC on the y-axis,
Coordinates of A, B and C will be (1, 0), (2, 0) and (0, 2).
When triangle ABC is dilated by a scale factor 4 about the origin,
Rule for dilation;
(x, y) → (4x, 4y)
New coordinates of the points A, B and C will be,
A(1, 0) → A'(4, 0)
B(-2, 0) → B'(-8, 0)
C(0, 2) → C'(0, 8)
Answer:
Correct
Step-by-step explanation:
New coordinates of the points A, B and C will be,
A(1, 0) → A'(4, 0)
B(-2, 0) → B'(-8, 0)
C(0, 2) → C'(0, 8)
Given x∥y and m∠2=23° .
What is m∠7?
Enter your answer in the box.
Answer:
angle2=23°
angle7=angle5
angle2=angle6
so,angle8=23°
total angle = 180°
angle7=180°-46°=134°÷2=67°
Using corresponding angles are equal property we found that m∠7 = 157°
What are corresponding angles?When two parallel lines are intersected by an transversal line then the pair of angles formed on one same side of transversal on both parallel lines are corresponding angles. As in the figure attached ∠ 1 and ∠5 are corresponding angles.∠4 and ∠8 are also corresponding angles.
Corresponding angles are always equal.
Given that x and y are parallel lines.
Then ∠2 and ∠6 are corresponding angles , therefore m ∠2 = m ∠6
Given that m∠2 = 23°
⇒ m∠6 = 23°
As ∠7 and ∠6 are on same line hence they are supplementary
m∠7 + m∠6 = 180°
⇒m∠7 + 23° =180°
⇒m∠7 =180°- 23° = 157°
Therefore, the measure of angle ∠7 is 157°
