Find the slope and the y-intercept of the line y=4x+6
Answers
Answer:
Slope: 4
Y-intercept: 6
Step-by-step explanation:
The equation is given to you in slope intercept form which is y=mx+b.
In this form m is the slope and b is the Y-intercept. Therefore all you have to do is take the value for m from the equation and put that down for the slope and the value for b as the y-intercept.

Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Gabriel remembers he has a coupon for $2 off his bill.
Gabriel has $30 to pay for the groceries. What simplified expression would represent the amount of change he should receive
Answers
Answer:
32 - 2.5x - 2y
Step-by-step explanation:
He bought 2.5 pounds weight of apples for x dollars a pound. Thus, cost is 2.5x.
He bought 2 bags of lettuce for y dollars each. Thus, cost is 2y
Total bill cost = 2.5x + 2y
We are told he has a coupon for $2 off his bill.
This means the amount he will pay will now be;
2.5x + 2y - 2
Gabriel has $30 to pay for the groceries.
Thus, his change will be;
30 - (2.5x + 2y - 2)
This gives;
32 - 2.5x - 2y

No choices solve on own
Answers
Answer:
y - intercept: 3/4
slope: -5/4
Step-by-step explanation:
put into slope-intercept form first, y = -5/4x + 3/4
then you can see that the slope and y - intercept are -5/4 and 3/4
Answer:
The answer for the y-intercept is (0, -3/4). The answer for the slope is -5/4.
Step-by-step explanation:
You know this because you must pull the 4 out of the equation, along with the y, so it is -4y=5x+3. You would put both of these numbers over 4: (5 and 3). A positive number which is 5, divided by a negative gives you negative so you can just say -5/4. Same with +3/-4. You can change it to -3/4, because positive over negative equals negative answer.

#13 and 14
Answers
Answer:
For number 13 you should get 14 is the width just divide what you got from multiplying the length and the other side. 2 and 95 could be possible answers of number 14.
Answer:
13. Width is 14 inches.
14. 5 and 38
Step-by-step explanation:
Volume (rectangular prism) = length*width*height
1428=17*w*6
w=1428/102
w=14 inches
Base area=length*width
∴Volume (rectangular prism) = Base area*height
190=Base area*height
Pick two numbers that multiply to give 190: 5 and 38.
Rearrange to make subject x 4(x-3)/a=y
Answers
Answer:
answer is x = ay + 12/4
Step-by-step explanation:
first we cross multiply on both sides which will give us this
4( x -3)=ay
we then open the brackets by multiplying 4 with x and -3 which gives
4x - 12= ay
then take 12 to the other side
4x - 12+12= ay + 12
4x = ay + 12
divide 4 on both sides
4x /4= ay + 12/ 4
therefore x = ay + 12/ 4

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.
At the end of the 4 years, how much interest in dollars and cents did the account earn?
Answers
Answer:
$1105
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 6500 × 0.0425 × 4 = 1105
I = $ 1,105.00
The simple interest accumulated
on a principal of $ 6,500.00
at a rate of 4.25% per year
for 4 years is $ 1,105.00.

m22 + m23 = 180°
m2l + m23 = 180°
Answers
Answer:
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.
Step-by-step explanation:
The correct question is attached.
Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.
If angles are supplementary to the same angle, then they are congruent.
∠1 and ∠3 are vertical angles
∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:
m∠1 + m∠2 = 180° (linear pair angles are supplementary)
m∠2 + m∠3 = 180° (linear pair angles are supplementary)
Hence using transitive property of equality:
m∠1 + m∠2 = m∠2 + m∠3
Using subtraction property of equality by subtracting m∠2 from both sides gives:
m∠1 = m∠3
∠1 ≅ ∠3 (vertical angles are congruent)
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.
