Grant bought strawberries and bananas from the grocery store to make smoothies. The total amount he spent can be represented by the expression 1.8s + 0.65b, where s is the number of pounds of strawberries and b is the number of pounds bananas. If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas, how much did he spend? Amount spent can be represented by the exper
Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)
= 4.86 + 0.91
= $5.77
He spent $5.77 on both items
Question 3
Write an equivalent expression to 13.4x - 5.9 - 7.1x + 13.5 with the fewest possible terms.
Answer:
A........................
Answer:
13.4x - 0.5
Step-by-step explanation:
13.4x - 5.9 - 7.1 + 13.5
This may seem complicated, but it is really pretty simple once you get the hang of it.
First, you would organize your terms.
13.4x - 5.9 - 7.1 + 13.5
Then you would add your like terms.
-5.9 - 7.1 + 13.5 = 0.5
So the answer to your problem would be 13.4x - 0.5

Answer: a = -3
Step-by-step explanation:
first, we remove the parentheses.
4 - 9/5a - 12/5 = 7
then, we calculate.
8/5 - 9/5a = 7
next, we multiply both sides.
8 - 9a = 35
then, we move the constant to the right.
-9a = 35 - 8
next, we calculate.
-9a = 27
finally, we divide both sides.
a = -3
Pls help me easy points if u know it
In a graph, x represents the number of months since a
business opened, and y represents the total amount of
money the business has earned. The following three
points are from the graph:
(2, 1990) (5, 4225) (9, 7205)
Find the slope and y-intercept. Explain what each
represents.
Answer:
My answer: To find the Slope the first we would need to use is the Slope-Intercept Formula. Y=mx+b. So 7205-4225=2980 and 9-5=4 So then you have to divide 2980/4=745 So the slope is 745. To find the Y-Intercept (b) we need to use the formula again. 4225= 745(5)+b so 745x5=3725 so we subtract on both sides 3725 is cancelled so 4225-3725=500 So the y-intercept is 500
Sample Response: The slope of this scenario is 745. The slope represents the profit made each month.

10.) Dilation with the center at the origin and a scale factor of 1/3.
Step-by-step explanation:
PAGE 1
3.) d
b/c the rule for x-axis is (x,y) --> (x, -y)
One of the points is (1, 1) ==> (1, -1)
4.) The rule for y-axis is (x, y) --> (-x, y)
A(-5, 3) --> A'(5, 3)
B(2, 6) --> B'(-2, 6)
C(-1, -7) --> C'(1, -7)
PAGE 2
5.) The rule for x-axis is (x,y) --> (x, -y)
A(-5, 3) ---> A'(-5, -3)
B(2, 6) ---> B'(2, -6)
C(-1, -7) ---> C'(-1, 7)
6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)
B(3, 4) ---> B'(4, -3)
PAGE 3
1.) On the transitions right is positive and left is negative
So 2 units to the right = +2
And 9 units down = - 9
So (x, y) --> (x + 2, y - 9)
2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)
B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)
C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)
D is correct b/c the translation is (x, y) --->(x -3 , y -3)
A(6, 6) --> A'(3, 3) B(7, 4) --> B'(4, 1) C(4, 4) --> C'(1, 1)
PAGE 4
7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)
The correct graph would show A(-3, 3) ----> (-3, -3)
The only graph that shows this is Graph C
8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)
The correct graph would show A(-3, 3) ----> A'(3, -3)
Graph B is the only one that ALL the angles follow this rule
PAGE 5
9.) It is Dilation with the center at the origin and a scale factor of 2.
B/c --> A(3, 3) ---> A'(6, 6) B(2, 0) ---> B'(4, 0) C(5, 2) ---> C'(10, 4)
(3*2= 6, 3*2=6) (2*2= 4, 0*2= 0) (5*2= 10, 2*2= 4)
10.) It is Dilation with the center at the origin and a scale factor of 1/3
B/c ---> A(-3, 6) --> A'(-1, 2) B(12, 3) ----> B'(4, 1) C(-6, -6) ---> C'(-2, -2)
(-3*1/3= -1, 6*1/3= 2) (12*1/3= 4, 3*1/3= 1) (-6*1/3= -2, -6*1/3= -2)

Answer:
B. {(-3, 4), (-8,0), (3, -8), (-3, -4)}
Step-by-step explanation:
B. is not a function because the x's repeat in this one.
If the x's repeat then it is not a function.
{(-3, 4), (-8,0), (3, -8), (-3, -4)}
The -3 repeats so it is not a function.
Y can repeat, but x cannot.

Step-by-step explanation:
Investors buy a studio apartment for $200,000 of this amount they have a down payment of $50,000 their down payment is what percent of the purchase price what percent of the purchase price would a $70,000 down payment be their down payment is what percent of the purchase price
Answer: 35%
Step-by-step explanation:
$70,000 was the down payment for a total price of $200,000.
Down payment percentage = 70,000 / 200,000
= 0.35
= 35%

The focus of a parabola is (-10, -7), and its directrix is x = 16. Fill in the missing terms and signs in the parabola's equation in standard form.
Answer:
The equation of the parabola in standard form is x = y²/52 + 7·y/26 - [tex]2\frac{3}{52}[/tex]
Step-by-step explanation:
The standard form of a parabola is a·y² + b·y + c
The focus of the parabola = (-10, -7), the directrix is x = 16, we have;
The coordinate of the focus is given as_F(h + p, k)
Where;
p = 1/(4·a)
The equation of the directrix is x = h - p
Therefore, given that the coordinates of the focus = (-10, -7), we have;
k = -7
Given that the equation of the directrix is x = 16, we have;
h - p = 16...(1)
h + p = -10...(2)
Adding equation (1) and (2), gives;
2·h = 6
h = 6/2 = 3
h = 3
From equation (1), p = h - 16 = 3 - 16 = -13
The general equation of the parabola is (y - k)² = 4·p·(x - h), therefore, substituting the values gives;
(y - (-7))² = 4 × (-13) × (x - 3)
(y + 7)² = -52·(x - 3)
y² + 14·y + 49 = -52·x + 156
x = (y² + 14·y + 49 - 156)/(-52) = (y² + 14·y + 49 - 156)/(-52) = y²/52 + 7·y/26 -107/52
Answer:
(y+7)^2= -52(x-3)

Ducklings cost $15 each. Chicks cost $12 each. You have $60 to spend on poultry
Answer:
If your question is how much money you have after you purchase a duckling and a chick, your answer would be $33. It seems to me like you posted the question without finishing it. I'm guessing you were about to mention how many ducklings and chicks you were going to buy and how much money you would have leftover for the poultry.
Step-by-step explanation:
To solve your problem you must add what you're buying and then subtract from your original amount.
For example: if you want one duckling and one chick and you would like to know how much money you have leftover to buy poultry. $15 + $12= $27 dollars in all. Then, you will subtract $27 dollars from $60, this way you know how much money you will have left in order to buy the poultry. $60 - $27= $33.
A scatter plot with a trend line is shown below. Which equation best represents the given data?
y=1/2x+2
y=1/2x+5
y=2x+5
Answer:
y=1/2x+5
Step-by-step explanation:
the y intercept is headed for five so we can cross off y=1/2x+2 and the slope is the flat to be 2x it has to be a slope of 1/2 it's much closer.
The only logical answer is y=1/2x+5
