M = 4
(x₁, y₁) = (3,-4)

The equation
y - y₁ = m(x - x₁)
y - (-4) = 4(x - 3)
y + 4 = 4x - 12
y = 4x - 12 - 4
y = 4x - 16

the answer is a

horsena [70]

0.50x-6=4

move -6 to the other side

sign changes from -6 to 6

0.50x-6+6= 4+6

0.50x= 10

divide by 0.50 for both sides

0.50/0.50x= 10/0.50

x= 20

Answer: x= 20

Safia opens a new savings account with a 2.25% simple interest rate. She deposits $3,500 and earned $3,696.88 total (with intere
Art [367]

Answer:

The money was left untouched for 2 years and 6 months or just 2.5 years

Step-by-step explanation:

In this question, we are asked to calculate the time taken for an amount deposited to earn a certain amount of interest.

Mathematically, simple interest can be calculated using the formula;

I = PRT/100

where I is the interest accrued which is 3696.88 - 3,500 = 196.88

P is the principal which is the amount deposited = 3,500 according to the question

R is the rate which is 2.25% according to the question

T is the time which we are to find

we can rearrange the formula making T the subject and we obtain the following;

T = 100I/PR

substituting the values listed above we have;

T = (100 * 196.88)/(3500 * 2.25)

T = 19688/7875

T = 2.5 years or 2 years 6 months

Make t the subject of the formula <br> P= 3-2t<br> —————<br> 4+t
Rufina [12.5K]

Answer:

t = \frac{3 - 4p}{p + 2}

Step-by-step explanation:

Given

P = \frac{3 - 2t}{4 + t}

Required

Make t the subject

P = \frac{3 - 2t}{4 + t}

Cross Multiply

P * (4 + t) = 3 - 2t

4p + tp = 3 - 2t

Collect Like Terms

tp + 2t = 3 - 4p

Factorize:

t(p+2) = 3 - 4p

Make t the subject

t = \frac{3 - 4p}{p + 2}

ankoles [38]

We know that he weeds gardens for 15 hours, and mows lawns for x hours.

If he wants to earn $252 per month, we can express the following

9\cdot15+9x\ge252

Now, we solve for x

\begin{gathered} 135+9x\ge252 \\ 9x\ge252-135 \\ 9x\ge117 \\ x\ge\frac{117}{9} \\ x\ge13 \end{gathered}<h2>Hence, he has to mow lawns for 13 hours to earn at least $252.</h2>
