Answer:

m=-1

Step-by-step explanation:

8m + 34 = 10 - 16m

fist add 16m to each side

8m+16m+34=10

then subtract 34 from each side

8m+16m=10-34

add like terms

24m=-24

divide both sides by 24

m=-1

Maria must cut an additional $70 from her expenses each month in order to save enough money to buy a new TV that costs $420 in 6 months. By allocating this additional amount towards her savings goal, she will be able to reach her target within the desired timeframe. It's important for Maria to review her budget and identify areas where she can reduce expenses in order to make room for the additional savings. This could involve cutting back on discretionary spending, finding ways to save on daily expenses, or exploring opportunities to increase her income.

Maria must cut an additional $70 from her expenses each month.

To determine how much additional money Maria must cut from her expenses each month to afford a new TV that costs $420 in 6 months, we divide the total cost by the number of months.

Additional money per month = Total cost / Number of months

Additional money per month = $420 / 6

Additional money per month = $70

With careful planning and commitment to her budget, Maria can achieve her goal of purchasing a new TV without compromising her financial stability.

Answer:

See below

Step-by-step explanation:

Slope-intercept form    ( or  slope -  y-axis intercept form)

 is   y = mx + b      where m = slope and   b is the y-axis intercept

so arrange each equation into this form

First one     y +3 = x        re-arrange to y = (1) x -3     slope =1  intercept = -3

Second one    2y-10 = -4x

                         2y = -4x +10

The correlation coefficient that represents the strongest relationship between two variables is -0.75.

In correlation coefficients, the absolute value indicates the strength of the relationship between variables. The strength of the association increases with the absolute value's proximity to 1.

The maximum absolute value in this instance is -0.75, which denotes a significant negative correlation. The relevance of the reverse correlation value of -0.75 is demonstrated by the noteworthy unfavorable correlation between the two variables.

Answer:

180 pages

Step-by-step explanation:

Let

x = total number of pages

Monday + Tuesday + Wednesday

2/15x + 1/3x + 2/9x

= (6x+15x+10x)/45

= 31/45x

Thursday

x - 31/45x

= (45x-31x)/45

= 14/45x

3/4 of 14/45x

= 3/4 * 14/45x

= 42/180x

Total pages read = 31/45x + 42/180x

= (124x+42x)/180

= 166/180x

If he still has 14 pages left to read on Friday

Total read from Monday to Thursday + Friday

x = 166/180x + 14

x - 166/180x = 14

(180x-166x)/180 = 14

14/180x = 14

x = 14 ÷ 14/180

x = 14 × 180/14

x = 180 pages

Answer:

max at (- 6, 18 )

Step-by-step explanation:

Given the equation of a parabola in intercept form

y = a(x + c)(x + d)

• If a > 0 then min vertex

• If a < 0 then max vertex

y = - 2(x + 9)(x + 3) ← is in intercept form

with a = - 2 < 0 then max vertex

y = - 2(x + 9)(x + 3) ← expand factors using FOIL

  = - 2(x² + 12x + 27) ← distribute parenthesis by - 2

y = - 2x² - 24x - 54 ← in standard form

with a = - 2 and b = - 24

The x- coordinate of the vertex is

x = - \(\frac{b}{2a}\) = - \(\frac{-24}{-4}\) = - 6

Substitute x = - 6 into the equation and evaluate for y

y = - 2(- 6 + 9)(- 6 + 3) = - 2(3)(- 3) = 18

vertex = (- 6, 18 ) and is a max

Step-by-step explanation:

To make pancakes, Sheila needs 2 ½ cups of flour. If Sheila only has 2/3 cup of flour, how much more flour does she need?

2 1/2 cups = 5/2 cups

Sheila has 2/3 cup flour but needs 5/2 cups.

Make denominators equal to 6:

Sheila has 4/6 cup flour but needs 15/6 cups so the difference is:

15/6 - 4/6  = 11/6 cups or 1 5/6 cups

Answer:

about 11.598 meters

Step-by-step explanation:

For this situation, we will primarily rely on the Pythagorean theorem.
We can draw a (straight) 10-meter line between Tim and the tree in order to further understand the problem. Since Tim and the tree are both standing straight, a perceived line will be parallel to the ground. Another line can be drawn between Tim's eyes and the top of the tree. Please view the attached image for reference. Using the Pythagorean theorem   (\(a^{2} +b^{2}=c^{2}\)), we can substitute 10 for a and 14 for c ---> giving us \(a^{2} +10^{2}=14^{2}\) or \(a^{2} =14^{2}-10^{2}\). We then subtract--->\(a^{2} =96\) and square root both sides to get a, which is equal to about 9.798 meters. However, this is only the height from Tim's eye level; therefore, to it, we must add 1.8 meters.
Our final solution is: about 11.598 meters.

First you have to calculate CB in order to use sin law to calculate ∠A

CB=\(\sqrt{18.4^{2} -13.2^{2} }\)

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

\(\frac{18.4}{sin90} =\frac{12.8}{sinA}\)       or    \(\frac{sin90}{18.4} =\frac{sinA}{12.8}\)

sinA=0.695...

A=44.079...

The highest degree term in the polynomial 5x^2 - 1091x - 70 is 5x^2. As x becomes very large, the other two terms become negligible compared to 5x^2.

To determine the monomial expression that best estimates f(x) for very large values of x, we need to consider the dominant term in the function f(x) = 5x^2 - 1091x - 70.

As x approaches infinity, the highest power term in the function, in this case, 5x^2, becomes the dominant term.

This is because the exponential growth of x^2 will surpass the linear growth of the other terms (1091x and 70) as x becomes increasingly large.

Hence, for very large values of x, we can approximate f(x) by considering only the dominant term, 5x^2. Neglecting the other terms provides a good estimation of the overall behavior of the function.

Therefore, the monomial expression that best estimates f(x) for very large values of x is simply 5x^2. This term captures the exponential growth that dominates the function as x increases without bound.

It is important to note that this estimation becomes more accurate as x gets larger, and other terms become relatively insignificant compared to the dominant term.

Therefore, the monomial expression that best estimates f(x) for very large values of x is 5x^2.

The statement cross-tabulation with two variables is known as twice-tabulation is false because there is no such term as "twice-tabulation" in the context of statistical analysis.

Cross-tabulation, also known as contingency table analysis, involves the analysis of categorical variables by creating a table that shows the frequency or distribution of one variable based on the levels of another variable.

It allows for the examination of the relationship between two variables, highlighting any associations or patterns that may exist. Each cell in the cross-tabulation table represents the count or proportion of observations that fall into specific combinations of categories from the two variables.

The term "twice-tabulation" does not exist in statistical literature and is not commonly used to refer to cross-tabulation with two variables. The correct term to describe this statistical technique is simply cross-tabulation or contingency table analysis.
