Answer: -12y²+7y²+20y-7
Step-by-step explanation:
Here, we need to use the concept of the FOIL method
First Outer Inner Last----------------------------------------------------------
Given
(-3y+1)(4y²-y-7)
Expand Parenthesis using FOIL
-12y³+3y²+21y+4y²-y-7
Put like terms together
-12y³+(3y²+4y²)+(21y-y)-7
Combine like terms together
-12y²+7y²+20y-7
Hope this helps!! :)

Step-by-step explanation:
The equation of the line A is 3x+2y=10.line B is parallel to line A and passes through the points (4,6).find the equation of the line B.
Answer: [tex]y=-\frac{3}{2}x+12[/tex]
Step-by-step explanation:
To find the equation of line B, we need to find the slope first, then the y-intercept. We first want to convert line A into slope-intercept form, so we can find the slope.
[tex]3x+2y=10[/tex] [subtract both sides by 3x]
[tex]2y=10-3x[/tex] [divide both sides by 2]
[tex]y=5-\frac{3}{2}x[/tex]
With the slope-intercept form of line A, we can see that the slope is [tex]-\frac{3}{2}[/tex]. We take the slope and the given point (4,6) to find the y-intercept of line B.
[tex]y=-\frac{3}{2}x+b[/tex] [plug in (4,6)]
[tex]6=-\frac{3}{2}(4)+b[/tex] [multiply]
[tex]6=-6+b[/tex] [add both sides by 6]
[tex]b=12[/tex]
With the y-intercept, we know the equation for line B is [tex]y=-\frac{3}{2}x+12[/tex].

the local market is selling a pound of bananas for $0.55. if you bought 8 bananas for $1.44, what is the unit rate?
Answer:
$0.18
Step-by-step explanation:
Given that :
Number of bananas purchased = 8
Cost at which the 8 bananas were purchased = $1.44
The unit price of bananas can be obtained using the relation :
Total Cost of bananas / number of bananas
Unit price = $1.44 / 8
Unit price = $0.18
Price per unit of banana = $0.18

Please help, I'm having a hard time with this ;-;
Answer:
A
Step-by-step explanation:
3 times steep means slope is 3 times
slope=4
new slope =3×4=12
translated 7 down means y intercept-7=1-7=-6
so new eq. is y=12x-6
Answer:
A
Step-by-step explanation:
So we know that the slope is 4, and we want to make it 3 times as steep, so that would be 12. The y-intercept is one and we want to move it down 7 units, 6-7= -1. So our final answer would be y= 12x-6!
y is directly proportional to the square root of x

Answer:
Step-by-step explanation:
y=k[tex]\sqrt{x}[/tex]
60=k[tex]\sqrt{36\\}[/tex] =k6
k=60/6 =10
This is your equation
y=10[tex]\sqrt{x}[/tex]
Put the numbers in

Assume that θ is an acute angle in a right triangle satisfying the given conditions. Evaluate the 5 remaining trigonometric functions. Sketch a triangle in the correct quadrant and label.
sec θ= 17/15
sin θ<0
Answer: See step by step. Replace the x with theta
Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.
We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.
We can find tangent by using the identity
[tex]tan^{2} (x)+ 1=sec^{2} (x)[/tex] where x is theta.
[tex]tan^{2} (x)+1=\frac{289}{225}[/tex]
[tex]tan^{2} (x)+\frac{225}{225} =\frac{289}{225}[/tex]
[tex]tan^{2}(x)=\frac{64}{225}[/tex]
tan x=[tex]\frac{8}{15}[/tex], Tangent in the fourth quadrant is negative so the answer is instead
[tex]tan x= -\frac{8}{15}[/tex]
We can find cotangent by taking the recipocial of tan so
[tex]cot=-\frac{15}{8}[/tex]
We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is
[tex]cos =\frac{15}{17}[/tex]
We can find sin by doing quoteint identies.
[tex]\frac{sin x}{cos x} =tan x[/tex]
[tex]\frac{ sin x}{15/17} =-\frac{8}{15}[/tex]
[tex]sin x= -\frac{8}{17}[/tex]
To find csc, take reciprocal of sine.
[tex]csc=\frac{-17}{8}[/tex]

Which statement is true about a graph representing the data? Select two options.
The number line of a dot plot would start at 1.
A dot plot would show 7 points for numbers greater than 2.
The intervals on a histogram should be 0 to 2, 3 to 4, and 5 to 6.
A histogram would have a maximum of 7 bars.
A histogram should not show a bar that includes 0 pieces of mail.
Answer:
B) A dot plot would show 7 points for numbers greater than 2.
D) A histogram would have a maximum of 7 bars.
Step-by-step explanation:
quiz on edg told me ;)
The true statements are:
B. dot plot would show 7 points for numbers greater than 2.
D. histogram would have a maximum of 7 bars.
What is a Dot Plot and a Histogram?A dot plot uses dots to show each data point, while for histogram, the frequency for the data values are depicted by bars or bins.
In the data ste given, 7 of the data points are greater than 2. So, the dot plot for the data distribution would display 7 points for values greater than 2.
Also, there are 7 different values, which are from 0 - 6. This will require 7 bars if we want to represent the data on a histogram.
Therefore, the true statements are:
B. dot plot would show 7 points for numbers greater than 2.
D. histogram would have a maximum of 7 bars.
