Answer:

-1

Step-by-step explanation:

4x-1=-4

-4+3=-1

The value of h(-1) is -1 after plugging the value of x = -1 in the function h(x) = 4x + 3 the answer is -1.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function h(x) = 4x + 3

Plug x = -1 in the above function:

h(-1) = 4(-1) + 3

h(-1) = -4 + 3

h(-1) = -1

The linear function can be defined as the relation between two variables, if we plot the graph of the linear function we will get a straight line.

If in the linear function, one variable is present, then the function is known as the linear function in one variable.

Thus, the value of h(-1) is -1 after plugging the value of x = -1 in the function h(x) = 4x + 3 the answer is -1.

The correct statement is B. If p → q is true and p is true, then q is true.

The correct statement is B. If p → q is true and p is true, then q is true.

This is known as the modus ponens rule and is a valid argument form in propositional logic. It states that if an implication is true and the antecedent (p) is true, then the consequent (q) must also be true.

For example, if p represents 'it is raining' and q represents 'the ground is wet', and the statement 'if it is raining, then the ground is wet' is true, and we know that it is indeed raining (p is true), then we can conclude that the ground is wet (q is true).

The perimeter of the isosceles triangle is C) 32 units.

Step-by-step explanation:

Step 1; First, we plot the three ends of the triangle. Assume the bottom left is A, the bottom right is B and the top end is C. The coordinates are;

A = (-6, -2), B = (6, -2) and = C (0, 6). A triangle's perimeter is the sum of its three side lengths. So we need to determine the side lengths of the given sides.

Step 2; To find the distance between A (-6, -2) and B (6, -2), we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between (-6, -2) and (6, -2) where (-6, -2) is (x1, y1) and (6, -2) is        (x2, y2).

Distance = √ (6 - (-6))² + (2 - (-2))² = √ 12² + 0² = √12² = 12 units.

Step 3; To find the distance between C (0, 6) and B (6, -2), we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between (0, 6) and (6, -2) where (0, 6) is (x1, y1) and (6, -2) is         (x2, y2).

Distance = √ (6 - 0)² + (-2 - 6)² = √ 6² + 8² = √36 + 64 =√100 = 10 units.

Step 4; To find the distance between C (0, 6) and A (-6, -2), we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between (0, 6) and (-6, -2) where (0, 6) is (x1, y1) and (-6, -2) is        (x2, y2).

Distance = √ (-6 - 0)² + (-2 - 6)² = √ 6² + 8² = √36 + 64 =√100 = 10 units.

Step 5; The perimeter of the triangle = 12 + 10 + 10 = 32 units, which is option C.

Answer:

x = 1/2, See Explanation Below

Explanation:

When you solve the equation, you have to take out the 6 first. The mistake is that you Marisol subtracted from 3 directly instead of factoring the x and the 3 out. Below is what you are supposed to do in order to get the right solution.

Step-by-step for Equation:

Final answer:

19/22 as a decimal is approximately 0.86363636..., and when rounded to the nearest tenth, it is 0.9.

Explanation:

To find what 19/22 is as a decimal rounded to the nearest tenth, we first need to perform the division of 19 by 22. When you carry out this division, the result is approximately 0.86363636... To round this to the nearest tenth, we would look at the first digit after the decimal point, which is 8, since the next digit (6) is greater than or equal to 5, we round up the 8 to 9. Therefore, 19/22 rounded to the nearest tenth is 0.9.

Answer:

4 pounds?????

Step-by-step explanation:

(NOT QUITE SURE WHAT THE QUESTION WAS SO MAY BE WRONG)

7 - 3 = 4 pounds????

The answer depends on the number of puppies that weigh 3 pounds and 7 pounds. If 'x' puppies weigh 3 pounds and 'y' puppies weigh 7 pounds, the number of 3 pound puppies that outweighed the 7 pounds ones can be found by subtracting 'y' from 'x'.

The phrasing of the question is a bit unclear. If we assume 'How many more puppies weighed 3 pounds than 7 pounds?' is the question, it's not possible to answer without the number of puppies that weigh 3 pounds and the number of puppies that weigh 7 pounds. Let's say you have 'x' puppies that weigh 3 pounds and 'y' puppies that weigh 7 pounds. The number of puppies that weigh more at 3 pounds than 7 pounds would be calculated as 'x' minus 'y'. If you have specific numbers to replace 'x' and 'y', substitute them in to find the number of puppies weighing more at 3 pounds.

To calculate the volume of an octagonal prism, find the area of the base using the formula A = 2(1 + √2)s² for a regular octagon, then multiply by the prism's height. Ensure all measurements are in the same units.

Explanation:

To find the volume of an octagonal prism, you need to calculate the area of the base octagon and then multiply it by the height of the prism. The formula for the area of a regular octagon (assuming all sides, s, are equal) is                       [tex]A = 2(1 + \sqrt{2} )s^2[/tex], where s is the length of one side. To find the volume, V, you then multiply this area by the height, h, of the prism: V = A*h = [tex]2(1 + \sqrt{2} )s^2*h[/tex]. It's important to ensure that all measurements are in the same units to get the volume in cubic units (e.g., cubic centimeters, cubic meters).

Step-by-step explanation:

The total number of cats in a local cat show is 250

Of these, 73 are orange, 11 are white, 80 are black, 27 are calico, 50 are gray, and 9 are tuxedo.

The probability of a

randomly selected cat from the show will be gray or tuxedo is

[tex] = \frac{50}{250} + \frac{9}{250} [/tex]

We simplify to get:

[tex] = \frac{50 + 9}{250} [/tex]

[tex] = \frac{59}{250} [/tex]

[tex] = 0.236[/tex]

To find the probability of selecting a gray or tuxedo cat in a cat show, add the number of gray and tuxedo cats, then divide by the total number of cats.

The probability that a randomly selected cat from the show will be gray or tuxedo is calculated by adding the number of gray cats and tuxedo cats, then dividing by the total number of cats.

Number of gray cats = 50

Number of tuxedo cats = 9

Total number of gray or tuxedo cats = 50 + 9 = 59

Probability = Number of gray or tuxedo cats / Total number of cats

Probability = 59 / 250 ≈ 0.236

Answer:

y = 2x + 23

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 )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (- 8, 7) into the partial equation

7 = - 16 + c ⇒ c = 7 + 16 = 23

y = 2x + 23 ← equation of line

Answer:

y=mx+c

y=2x+c

Y intercept(c) 23 - to find y we have to input the values

7=2*-8+c

7=-16+c

23=c

Answer: Since Yuko used 1.5x the amount of eggs that he should have used, in order to find the answer you need to take the amount of flour Yuko was SUPPOSED to use and multiply it by 1.5

If Yuko uses 3 eggs instead of 2, Yuko should multiply the amount of flour required by 3/2 or 1.5 to maintain the correct proportionality, according to the recipe's proportions.

Based on the problem, we are dealing with ratios in a recipe. The ratio provided is flour to eggs. If we had an example ratio, let's say 2 cups flour to 1 egg, and Yuko uses 3 eggs instead of 1, we'd have to scale up the flour by the same factor to keep the proportions in the pancake batter consistent.

Since Yuko uses three times the eggs (3 is three times larger than 1), he should also use three times the amount of flour. So for our example, if 1 egg needed 2 cups of flour, 3 eggs (which is three times 1 egg) would require 6 cups of flour (three times 2 cups) to maintain the correct proportionality.

Thus, if Yuko accidentally uses 3 eggs instead of 2 eggs, he needs to also increase the amount of flour used proportionately to maintain the same pancake consistency according to the recipe's ratios.
