Answer:
70
Step-by-step explanation:
Answer:
The answer is 70.
Step-by-step explanation:
In order to find the value of k(-5), you have to substitute the value of x into the function k :
[tex]k(x) = 6x + 100[/tex]
Let x = -5,
[tex]k ( - 5) = 6( - 5) + 100[/tex]
[tex]k( - 5) = - 30 + 100[/tex]
[tex]k( - 5) = 70[/tex]
5 + x = -2
I need work and answer!!!!
We need to get x by itself.
We do that by subtracting 5 from both sides.
This leaves us with x = -7.
So x = -7 is the solution.
Answer:
The final answer is [tex]x = -7[/tex] .
Step-by-step explanation:
Solve the equation:
[tex]5 + x = -2[/tex]
Subtract both sides by 5:
[tex]5 - 5 + x = -2 -5[/tex]
[tex]x = -7[/tex]
So, therefore, [tex]x = -7[/tex] is the final answer.

1-2c = -8
-8/7r = 6
4-4 (4-x) -4x = 18x
1/5m + 3 = 7/5m
Answer:
1. c = 9/2
2. r = 21/4
3. x = -2/3
4. m = 5/2
Step-by-step explanation:
1.
1 - 2c = -8
Subtract 1 from both sides to isolate the variable:
-2c = -8 - 1 = -9
Divide by -2 to further isolate the variable:
c = (-9) / (-2) = 9/2
So, the answer is c = 9/2.
2.
-8/7r = 6
To isolate the variable, divide both sides by -8/7:
r = (-6) / (-8/7)
Remember that when dividing fractions, it's the same as multiplying by the reciprocal of the divisor, so:
r = (-6) / (-8/7)
r = (-6) * (-7/8) = 42/8 = 21/4
So, the answer is r = 21/4.
3.
4 - 4 * (4 - x) - 4x = 18x
We need to use order of operations and expand the 4 * (4 - x) part first:
4 * (4 - x) = 16 - 4x
Put this back in:
4 - (16 - 4x) - 4x = 18x
4 - 16 + 4x - 4x = 18x
Combine like terms:
-12 = 18x
Divide by 18 on both sides:
x = -12/18 = -2/3
So, the answer is x = -2/3.
4.
1/5m + 3 = 7/5m
Subtract 1/5m from both sides:
3 = 7/5m - 1/5m = 6/5m
Divide both sides by 6/5:
m = 3 ÷ (6/5) = 3 * (5/6) = 15/6 = 5/2
So, the answer is m = 5/2.
Answer:
1. c = 9/2
2. r = -21/4
3. x = -2/3
4. m = 5/2
Step-by-step explanation:
1-2c = -8
1 + 8 = 2c
9 = 2c
c = 9/2
-8/7r = 6
r = 6 × 7/-8
r = 3 × 7/-4
r = -21/4
4-4 (4-x) -4x = 18x
4 - 16 + 4x - 4x = 18x
-12 = 18x
x = -12/18
x = -2/3
1/5m + 3 = 7/5m
3 = (7/5 - 1/5)m
3 = 6/5m
m = 3 × 5/6
m = 5/2

Efficient Homemakers Ltd. makes canvas wallets and leather wallets as part of a money making project. For the canvas wallets, they need three yards of canvas and two yards of leather. For the leather wallets, they need three yards of leather and two yards of canvas. Their production unit has purchased 36 yards of leather and 40 yards of canvas. Let x be the number of leather wallets and y be the number of canvas wallets. If the profit on a canvas wallet is $25 and the profit on a leather wallet is $40, write a function for the total profit on both wallets.
Answer: F(x, y) = 40x + 25y
Step-by-step explanation:
Given the following :
x = number of leather wallets
y = number of canvas wallets
PROFIT on canvas wallet = $25
PROFIT on leather wallet = $40
Function that calculates the total profit on both wallets:
Profit on each wallet type is the product of the profit per wallet and the number of wallet.
The total profit generated on each wallet type is given by :
F(x) = 40x - - - - (1) leather wallet
F(y) = 25y - - - - (2) canvas wallet
Adding (1) and (2) to get total profit on both wallets:
F(x, y) = 40x + 25y

Fill in the y values of the t–table for the function y=\root(3)(x)
You can use a graphing calculator to have a function y = x^(1/3) and see what the y values are for the particular x values shown. Alternatively you can compute each input to get (-8)^(1/3) = -2, and (-1)^(1/3) = -1 and so on. The exponent of 1/3 is another way of writing cube root.
The cube root is the opposite of cubing something. If we go from 2 to 2^3 = 8, then reversing this has us go from 8 to 2. Think of a block of clay that is 2 by 2 by 2. The volume of this block is 8 cubic units. If you want to find the side length, then you would apply the cube root (or do guess and check).

Then add 22 and 6.
4y=28
Divide each term in 4y=28 by 4
4y÷4=28÷4
Cancel the common factor of 4 in the first part of the equation so it looks like this...
y=28÷4
Divide 28 by 4.

Correct Question
A standard deck of 52 cards contains 4 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 2 through 10, a jack, a queen, a king, and an ace.
Anthony decides to pick one card at random from a standard deck of 52 cards. Let A be the events that he chooses an ace and H be the event that he chooses a heart.
What is P ( A or H), the probability that the card Anthony chooses is either an ace or a heart?
Answer:
2/13
Step-by-step explanation:
From the question, we have in total, 52 cards.
Step 1
We find the probability that Anthony chooses an Ace.
Number of ace cards in each of four suits namely spades, hearts, diamonds and clubs = 1
Therefore, total number of ace cards out of 52 cards = 4
P(A) = 4/52
Step 2
We find the probability that Anthony chooses an Ace.
Probability that Anthony chooses an heart P(H) = 4/52
Step 3
The probability that the card Anthony chooses is either an ace or a heart
P ( A or H) = P(A) + P(H)
= 4/52 + 4/52
= 8/ 52 = 2 /13
