find the product of (5x+4)(5x-4)
Answer:
25x² - 16
Step-by-step explanation:
Given
(5x + 4)(5x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 4) + 4(5x - 4) ← distribute parenthesis
= 25x² - 20x + 20x - 16 ← collect like terms
= 25x² - 16

The school library has 2,469 books. Two-thirds of them are paperbacks. How many
books are paperbacks?
Answer:
2469 x 2/3= 1646
personally, I solve it by dividing the 2469 by 3 to get 1/3.
2469/3= 823
then, double it to get 2/3.
823x2= 1646

Jordan and Roman travel the same route to work. Jordan leaves for work one morning and drives at a rate, r, of 56 mph. Roman leaves the house soon after, when Jordan has already traveled 2 mi. Roman drives at a rate of 60 mph. How long after Jordan leaves home will Roman catch up to her? How many miles into their commute will this occur?
Which system of equations models this problem?
d = 56t
d = 58t
d = 56t
d = 62t
d = 56t
d = 60t – 2
d = 56t
d = 60t + 2
Step-by-step explanation:
D= 56t
D= 60t -2
D= Distance T=time d = 56t (Jordan) d = 60t - 2 (Roman)
d = 56t d = 60t - 2
56t = 60t - 2 d = 56(1/2) d = 60(1/2) - 2
-60t -60t d = 28 d = 30 - 2 = 28
-4t = -2
t = 1 / 2

Jake’s mom filled a 2-liter container with juice. Then Jake poured 2 glasses of juice. Each glass had exactly 400 milliliters of juice. How many liters of juice remain in the container?
12.00 liters
1.2 liters
Answer:
1.2
Step-by-step explanation:
1 liter = 1000 milliliters
if there’s two liters, that’s 2000 milliliters. the mom then poured 2 glasses each with 400 milliliters, or 800 milliliters in total. 2000 - 800 = 1200. 1200 milliliters converted into liters = 1.2 liters.
Answer:
1.2 liters

The dot plot shows a random sample of the number of fish caught and released by 30 participants during a two-day fishing derby. Two dot plots show the number of fish caught on days 1 and 2. The dot plot for day 1 has dots as follows: 3 above 1, 6 above 2, 6 above 3, 6 above 4, 6 above 6, and 3 above 6. The dot plot for day 2 has dots as follows: 3 above 1, 3 above 2, 4 above 3, 6 above 4, 7 above 5, and 7 above 6. Use the mean value of each data set to make an inference about the number of fish caught each day. On average, most participants caught and released 5 or more fish. More participants caught 6 fish than any other number. The same participants who caught and released 1 fish the first day caught and released 1 fish the second day. On average, participants caught and released more fish on Day 2.

is y+7=2x a direct variation
Answer:
No, y+7=2x does not represent direct variation
Step-by-step explanation:
No, y+7=2x does not represent direct variation, because of the constant (initial value) 7.
y = 2x represents direct variation; y = 2x - 7 does not.
Smoothies weren't cutting it so we went to Red Robin to order a burger. Our bill was $5.79. Avon has a 5.25% tax and our
waitress earned a 15% tip. What was the total bill?
Answer:
$6.96
Step-by-step explanation:
5.25% of 5.79
5.79 × 5.25/100 = $0.303975 or $0.30
15% of 5.79
5.79 × 15/100 = $0.8685 or $0.87
total
$5.79 + $0.30 + $0.87 = $6.96
the slope of the line that passes through the points (-2,-1) and (-2,7)
Answer:
The answer is zero.
Step-by-step explanation:
When you put the coordinates in the point-slope formula, it will be 7 - (-1) over -2 - (-2), which is 8/0. When the denominator is zero in the fraction, the answer is zero.

Your answer is 140
Which transformation, when performed on the triangle ABC, will result in the transformed figure A'B'C being similar but NOT congruent to the original triangle?
Answer:
b. a dilation by a scale factor of 2
Step-by-step explanation:
Which transformation, when performed on the triangle ABC, will result in the transformed figure
A'B'C' being similar but NOT congruent to the original triangle?
a. a reflection over the x-axis
b. a dilation by a scale factor of 2
C.a translation two units to the right
d. a rotation 90° clockwise about the origin
Solution:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Rigid transformation are transformation that preserves the size and shape of a figure. Examples of rigid transformation are reflection, translation and rotation.
Dilation preserves the shape but not the size of a figure.
If translation, rotation or reflection is done on triangle ABC, the transformed figure would be congruent to the original triangle. But, if dilation is done, the transformed figure would be similar but NOT congruent to the original triangle.

help pls!! right answer = gets brainiest :)
Answer: Option 2.
Step-by-step explanation: 3x−4y=6
3x−4y+4y=6+4y
3x/3=4y+6/3
x=4/3y+2
7x-6y=9
7(4 /3 y+2)−6y=9
10 /3 y+14=9
10 /3 y+14+−14=9+−14
10 /3 y /10 /3 = −5 /10 /3
y= −3 /2
x= 4/ 3 y+2
x= 4 /3 ( −3 /2 )+2
x=0
x=0 and y= −3 /2
