Answer:
y=5/4-7x/4
Step-by-step explanation:
Answer:
so your anwser would be Y = [tex]\frac{7x}{4}[/tex] + 5
Step-by-step explanation:
y = 5 + [tex]\frac{7x}{4}[/tex]
Reorder 5 and [tex]\frac{7x}{4}[/tex]
Y = [tex]\frac{7x}{4}[/tex] + 5
after this step nothing else can be done

The measure of an angle is 82 °. What is the measure of its complementary angle?
Answer
The answer will be 8⁰
Step-by-step explanation:
Complementary angles always add up to 90⁰ degrees
Answer:
8 degrees (see explanation below)
Step-by-step explanation:
A complimentary angle is when 2 angles are added together to make a 90 degree angle. So if the measure of the current angle is 82, then the other measure is 8.
the measure of angle JKM=?
the measure of angle JMK=?
Answer:
JKM = 36 degrees
JMK = 54 degrees
Step-by-step explanation:
Subtract right angle ( 90) from the 54 degress known and then you get 36 for JKM.
By looking at the equation, what can be predicted about the end behavior of the graph for x^3-5x^2+8x-4=0
Answer:
The curve starts low to the left and goes high to the right
Step-by-step explanation:
suppose the equation for line a is given by y=-3/4x-2. if line a and a line b are perpendicular and the point -4, 1 lies on line b then write an equation for line b
Answer:
y=4/3x+19/3
Step-by-step explanation:
perpendicular = slope is the negative reciprical.
plug in the point (-4,1) for (x,y)
1(y)=4/3(-4)+b
1=-16/3+b
b=19/3

Your answer:
A butcher has 3 pounds of ground beef that will be priced at $5.53 per pound. He divides the meat into
4 equal packages.
To the nearest cent, the price of each package is ?
Answer:
3 cents
Step-by-step explanation:
First you have to find the price of the 3 pounds of ground beef. Which is 3 • 5.53= 11,06 and then you are going to divide that by 4. Which is 11,06 ÷ 4 = 2,765
Among 2450 randomly selected male car occupants over the age of 8, 76% wear seatbelts. Among 2900 randomly selected female car occupants over the age of 8, 74% wear seat belts. Use a 0.1 significance level to test the claim that both genders have the same rate of seat belt use. Does there appear to be a gender gap?
a. There appears to be a gender gap because there is not a significant difference in the proportions.
b. There does not appear to be a gender gap because there is a significant difference in the proportions.
c. There does not appear to be a gender gap because there is not a significant difference in the proportions.
d. There appears to be a gender gap because there is a significant difference in the proportions.
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size for male car occupant is [tex]n_1 = 2450[/tex]
The number that wear seat belt is [tex]k_1 = \frac{76}{100} * 2450 = 1862[/tex]
The sample size for female car occupant is [tex]n_2 = 2900[/tex]
The number that wear a seat belt is [tex]k_2 = \frac{74}{100} * 2900 = 2146[/tex]
Generally the population proportion is mathematically represented as
[tex]p = \frac{x_1 + x_2 }{n_1 + n_2 }[/tex]
=> [tex]p = \frac{1862 + 2146 }{2450 + 2900 }[/tex]
=> [tex]p = 0.7492[/tex]
The sample proportion for male car occupant is
[tex]\^ p_1 = \frac{k_1}{n_1}[/tex]
=> [tex]\^ p_1 = \frac{1862}{2450}[/tex]
=> [tex]\^ p_1 = 0.76[/tex]
The sample proportion for female car occupant is
[tex]\^ p_2 = \frac{k_2}{n_2}[/tex]
=> [tex]\^ p_2 = \frac{2146}{2900}[/tex]
=> [tex]\^ p_1 = 0.74[/tex]
The null hypothesis is [tex]H_o : p_1 = p_2[/tex]
The alternative hypothesis is [tex]H_a : p_1 \ne p_2[/tex]
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{\frac{p(1 -p )}{ n_1 + n_2} }[/tex]
=> [tex]SE = \sqrt{\frac{0.7492 (1 -0.7492 )}{ 2450 + 2900} }[/tex]
=> [tex]SE = 0.005926[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\^ p_1 - \^ p_2}{SE}[/tex]
=> [tex]z = \frac{0.76 -0.74}{0.005926}[/tex]
=> [tex]z = 3.37[/tex]
From the z table the area under the normal curve to the right corresponding to 3.37 is
[tex]P(Z > 3.37) = 0.00037584[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > 3.37)= 2* 0.00037584 = 0.0007 5[/tex]
From the value obtained we see that [tex]p-value < \alpha[/tex] hence
The decision rule is
Reject the null hypothesis
The conclusion is
There appears to be a gender gap because there is a significant difference in the proportions

tum. All rights reserved.
The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10
The equation is given as:
[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]
Take the LCM
[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]
This gives
[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]
Cross multiply
[tex]40(2x + 18) =x(x + 18)[/tex]
Expand
[tex]80x + 720 =x^2 + 18x[/tex]
Collect like terms
[tex]x^2 + 18x - 80x -720 = 0[/tex]
[tex]x^2 - 62x -720 = 0[/tex]
Using a graphing calculator, we have:
[tex]x = 72\ or\ x =-10[/tex]
The value of x cannot be negative, because of the context.
So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

Solutions:
m - 6 1/4 = 9 3/8
-3 1/8 - 6 1/4 = 9 3/8
Solve the inequality. Define the solution set using numbers and symbols.
[tex]\frac{x+17}{x^2 +3} \geq 4[/tex]
(x + 17) / (x ² + 3) ≥ 4
x + 17 ≥ 4 (x ² + 3)
4x ² - x - 5 ≤ 0
(4x - 5) (x + 1) ≤ 0
The left side is equal to 0 when either
4x - 5 = 0 or x + 1 = 0
x = 5/4 or x = -1
For x < -1, we have both x + 1 < 0 and 4x - 5 < 0, so their product is positive and there are no solutions to the inequality in this interval.
For -1 < x < 5/4, we have x + 1 > 0 and 4x - 5 < 0, so their product is negative.
For x > 5/4, we have both x + 1 > 0 and 4x - 5 > 0, giving a positive product and thus no additional solutions.
The solution set is then the second interval, but including the endpoints since that makes the expression on the left equal to 0:
-1 ≤ x ≤ 5/4
x = -11 + 7y
5x + 2y = -18
Answer:
x = -4
y = 1
(-4,1)
Step-by-step explanation:
x = -11 +7y
5x + 2y = -18
This is a Substitution problem, so you put x = -11+7y into 5x+2y = -18
5(-11 +7y)+2y = -18
5(-11) = -55
5(+7y) = 35y
-55+35y+2y = -18
Now you add 35y and 2y which gives you 37y
-55+37y = -18
Now you add +55 from -55 and -18
37y = 37
You divide each side by 37 so that y = 1
Now you plug y(1) into the equation x = -11+7y
x = -11+7(1)
-11+7 = -4
x = -4

Algebra Find the value of each variable using the given chord, secant, and tangent lengths. If the answer is not
a whole number, round to the nearest tenth.
Answer/Step-by-step explanation:
15. Based on the intersecting Chords Theorem, thus,
[tex] x \times 8 = 20 \times 6 [/tex]
[tex] 8x = 120 [/tex]
Divide both sides by 8
x = 15
17. Based on the two secants intersecting theorem,
[tex] (c + 13) \times 13 = (20 + 11) \times 11 [/tex]
Solve for c
[tex] 13c + 169 = (31) \times 11 [/tex]
[tex] 13c + 169 = 341 [/tex]
Subtract 169 from each side
[tex] 13c = 172 [/tex]
Divide both sides by 13
c = 13.2 (nearest tenth)
19. ✔️Based on the two secants intersecting theorem,
[tex] (x + 5) \times 5 = (15 + 7) \times 7 [/tex]
Solve for x
[tex] 5x + 25 = (22) \times 7 [/tex]
[tex] 5x + 25 = 154 [/tex]
Subtract 25 from each side
[tex] 5x = 129 [/tex]
Divide both sides by 5
x = 25.8
✔️according to the tangent and secant theorem, thus:
[tex] y^2 = 7 \times (15 + 7) [/tex]
Solve for y
[tex] y^2 = 7 \times (22) [/tex]
[tex] y^2 = 154 [/tex]
Square both sides
y = 12.4 (nearest tenth)
