Write the following equation in slope intercept form: y-6=4(x+3)

Answers

Answer:

y =4x+ 18

Step-by-step explanation:

Slope intercept form: y = mx + b

y -6 = 4(x + 3)

y - 6 = 4x + 12

Add 6 to both side

y = 4x + 12 + 6

y = 4x + 18

>> Answer

______________

[tex] \: [/tex]

y - 6 = 4(x + 3)

y - 6 = 4x + 12

y = 4x + 12 + 6

y = 4x + 18✔

Harita must memorize 90 measures of music for her cello solo at a concert. She plans on memorizing 18 new measures for every 3 days of practice. Which equation can be used to determine m, the number of measures Harita still needs to memorize, as a function of d, the number of days of practice since she began learning the piece?

m = 72 – 15d
m = 90 – 6d
m = 101 – 21d
m = 108 – 3d

Answers

Answer:

m = -90 - 6d

Step-by-step explanation:

18 ÷ 3 = 6 { She needs to memorize six measures a day. }

m = 90 - 6d { She has memorized bd measures }

Tom makes $249.25 in 5 days. How much does he make in 4 days?

Answers

Answer:

$199.4 in four days

$49.85 in one day

Step-by-step explanation:

249.25 / 5 =49.85

49.85 x 4 = 199.4

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The amount that Tom makes in 4 days is $199.4.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Tom makes $249.25 in 5 days. Therefore, the amount that Tom makes in a day is,

Amount Tom makes in a day = $249.25 / 5 days

= $49.85 per day

The amount of money that Tom can make in 4 days is,

Amount = $49.85 per day × 4 days

= $199.4

Hence, the amount that Tom makes in 4 days is $199.4.

4(9x+6)=36x-7 And the solution is x=

Answers

Answer:

no solution

Step-by-step explanation:

4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4

36x + 16 = 36x - 7 ( subtract 16 from both sides )

36x = 36x - 23 ( subtract 36x from both sides )

0 = - 23 ← False statement

you and your friend went shopping. you bought 3 shirts and 4 sweaters for $69. your friend bought 6 shirts and 2 sweaters for $66 how much does one shirt and one sweater coat each

I need this answered quickly

Answers

Answer:

Shirt = $7

Sweatshirt = $12

Step-by-step explanation:

Let T represent shirts and S to represent sweatshirts

you bought 3T + 4S = 69

your friend bought 6T + 2S = 66 multiply second equation by -2

-2 x 6T + 2S = 66

-12T - 4S = -132 now find the sum of this and first equation

3T + 4S -12T - 4S = 69 - 132 add like terms

-9T = -63 divide both sides by -9

T = 7 this is the cost of one shirt to find the cost of a sweatshirt we replace the T in any equation with 7

3T + 4S = 69

3*7 + 4S = 69

21 + 4S = 69 subtract 21 from both sides

4S = 48 divide both sides by 4

S = 12

Step-by-step explanation:

The sum of the exterior angles of a polygon always will equal 360°.

(3x + 6) + 41 + (6x - 5) + (4x + 7) + 62 + (7x - 11) = 360°

(3x + 6x + 4x + 7x) + (6 + 41 - 5 + 7 + 62 - 11) = 360°

20x + 100 =360°

20x = 260

x = 260/20

x = 13

Step-by-step explanation:

DAC = 99

DAB = 59

B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.

So 99 - 59 = 40

CAB must be 40°

Answers

Answer:

Step-by-step explanation:

19 x 2 = 38

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

A proportion relationship is a direct relationship between two variables thus y = 4x will be the proportional relationship between x and y thus option (D) will be correct.

What are the ratio and proportion?

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

A proportional relationship is given as,

A ∝ B

Removing proportionality

A = kB

Here, k is the constant of proportionality.

As per the given in last option,

y = 4x

x = (1/4)y

Removing constant.

x ∝ y

Hence "A proportion relationship is a direct relationship between two variables thus y = 4x will be the proportional relationship between x and y".
