Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per
pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?
Answer: Just bought 21 pounds of coffee A
Step-by-step explanation:
We know that she consumed twice as many pounds of Type B coffee as type A.Then let the total number of cafe feet A=x ; then the number of cafe feet B=2x . We also know that the total number of feet cost $336And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95 Then :[tex]\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}[/tex]For each graph below, state whether it represents a function.

y=2x =2 and y2= 4x+4
Answer:
x=−2
y=−4
y² =−2
Step-by-step explanation:
Im going to assume youre saying to compare the two
if so, then theyre the same equation/line
2y =4x +4 is the same y = 2x + 2 since 2y = 4x + 4 is just y=2x+2 but everything is multiplied by 2
hope this helps :)
Somebody explain!!!!!!!!!!!
Answer:
$190
Step-by-step explanation:
Let's call the original price of the jacket "x".
If the new cost of the jacket is $87, we can represent this as x/2-8=87. By solving for x, we see that the original price of the jacket is $190
Answer:
I think the answer would be 182
Step-by-step explanation:
87x2= 174
174+8= 182

What is an equation of the line that passes through the point (-6,-1) and is perpendicular to the line 6x-y=7
Answer:
y=-1/6x-2
Step-by-step explanation:
Lets find the slope of the given line
6x-7=y,m=6
The slope of the perpendicular line would be=-1/6
Using the point-slope form y-y1=m(x-x1)
y--1=-1/6(x--6)
y+1=-1/6(x+6)
6y+6=-x-6
6y=-x-6-6
6y=-x-12
y=-1/6x-2

Step-by-step explanation:[tex] \sf 1\frac{2}{3} + 2 \frac{3}{4} + 3\frac{5}{6} [/tex]
[tex] \sf = \frac{3 + 2}{3} + \frac{4 \times 2 + 3}{4} + \frac{6 \times 3 + 5}{6} [/tex]

[tex] \sf = \frac{53}{12} + \frac{46}{12} [/tex]
[tex] \sf = \frac{99}{12} [/tex]
[tex] \sf = \frac{10}{1} - \frac{99}{12} [/tex]

© Andy's y-values increase at 2 times the rate of date's y-values.
D Andy's y-values increase at 3 times the rate of Kate's y-values.
Answer:
Answer is C
Andy's Y value increases 2 times more
Answer:
B)
Step-by-step explanation:
If you look at Kate's y column, you will see that her pattern goes by 2,4,6 and 8.
It increases by 2.
At the same rate, Andy's increases by 4.
Therefore, B would be the correct answer.
Write an equation of a line in point-slope form with the
information given.
1. passes through: (6, 0); slope: - 1/6
Answer: (y − 0) = -(1/6)(x − 6) or y=-(1/6)(x-6)
Step-by-step explanation:
An equation in Point Slope form: y − y1 = m(x − x1), where m is the slope and x1 and y1 are provided as a single point, (x1,y1). We have slope(m) = -(1/6) and are given (6,0). Therefore:
(y − 0) = -(1/6)(x − 6) (Point slope form)
y = -(1/6)(x-6)
Rewriting this into standard form, y = mx + b
y = -(1/6)x + 1
There are 454 grams in a line. There are 16 ounces in a pound.How many grams are in an ounce?

Which point is an x-intercept of the quadratic function
f(x) = (x – 3)(x + 2)?
A(3, 0)
B(0, 2)
C(0, -2)
D(-3, 0)
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form [tex]f(x)=(x-h)(x-k)[/tex], where h and k are real numbers, the roots are [tex](h, 0)[/tex] and [tex](k, 0)[/tex].
Our parabola has a plus, though. That's a problem, right?
No! [tex]x+2=x-(-2)[/tex], so there's no problem. So, our roots are [tex](3, 0)[/tex] and [tex](-2, 0)[/tex].
So, the answer is A and we're done!

solve for y
2x+3y=r
(Show solving steps please)
2x + 3y = r
---Subtract 2x from both sides
3y = r - 2x
---Divide both sides by 3
y = (1/3)(r) - (2/3)(x)

Is 2750 a reasonable answer for 917 * 33 explained
Answer:
No
Step-by-step explanation:
To make this simpler, we will round each number. 917 rounds to 900 and 33 rounds to 30. 900 * 30 = 27,000. We can do this in our head because 9 * 3 = 27, and there are three zeros total between 900 and 30, so we add three zeros after 27. 2750 is not a reasonable answer because the true answer is about 10 times greater than 2750.
