Answer:
Step-by-step explanation:
when you multiply a negative times a negative it turns into a positive number
-4.5·2=9
If you did * for exponents then the answer is 20.25
same rule applies, when you multiply a negative times a negative it turns into a positive number
-4.5·-4.5=20.25
How can you find a function that has
roots?
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Answer:
The roots of a function are the x-intercepts.
Step-by-step explanation:
Negative or positive 576(-999)(-1)(-1)(-3)
Answer:
Positive
Step-by-step explanation:
neg x neg = pos
neg x neg = pos
pos x pos x pos = pos
Answer:
Positive.
Step-by-step explanation:
Start with parenthesis, we have a negative x negative = positive times the next negative = negative times the last parenthesis which is negative so negative times negative = positive. Then times the positive by the remaining number outside parenthesis and get positive times a positive = positive.
I need to know the all the blanks including the equation on the bottom and y intercept and slopes
Answer:
See answers below
Step-by-step explanation:
Using the coordinates from the table (0, 12) and (1, 14)
m = 14-12/1-0
m = 2/0
m = 2
Hence the slope of the table is 2
y intercept occurs at x = 0
Substitute m = 2 and (0,12) into the equation y = mx+c
12 = 2(0) + b
12 = b
b = 12
Hence the y-intercept is 12
Get the equation
Recall that y = mx+c
y = 2x + 12
Hence the required equation is y = 2x+12
help me out guys my brain cells aren't working correctly.
Answer:
I'm not sure bout what to do so I did this instead.
Step-by-step explanation:
3x + 4x + 19 = 180
7x + 19 = 180
7x + 19 - 19 = 180 - 19
7x = 161
7x ÷ 7 = 161 ÷ 7
x = 23
_________________________
3x + 4x + 19 = 180
3(23) + 4(23) + 19 = 180
69 + 92 + 19 = 180
180 = 180
________________________
3x = ?
3(23) = ?
69 = ?
__________________________
4x + 19 = ?
4(23) + 19 = ?
92 + 19 = ?
111 = ?

3. Una caravana migrante, procedente de Honduras debe recorrer 5 km en 4 días si quiere alcanzar al tren conocido como la Bestia que los conducirá al Norte de México, el primer día debido al intenso calor solo avanzan 1200 metros, el segundo día ya los espera un retén militar pero aun así avanzan 1 2/3 km, el tercer día caminan un kilómetro y medio. Si quieren llegar a tiempo para tomar el tren, ¿Cuánto debe recorrer la caravana el último día? A) 18/29 B) 19/30 C) 20/31 D) 21/32
Answer:
B) 19/30
Step-by-step explanation:
Se deben recorrer 5km en total, en números fraccionarios se recorren:
1er día:
1200m = 1.2km = 6/5km
2do día:
1 + 2/3km = 5/3km
3er día:
1.5km = 3/2km
La suma da:
6/5km + 5/3km + 3/2km = 36/30km + 50/30km + 45/30km = 131/30km.
5km son 150/30km.
150/30km - 131/30km = 19/30 km
La respuesta es:
B) 19/30I need an answer quickly please and thank you

At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41. Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68. How much does the candy cost?
Answer:
Cost of a pound of Jelly beans = x = $7
Cost of a pound of Gummy worms = y = $9
Step-by-step explanation:
Let us represent
Cost of a pound of Jelly beans = x
Cost of a pound of Gummy worms = y
At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41.
2x + 3y = 41....... Equation 1
Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68.
2x + 6y = 68...... Equation 2
Combining Equation 1 and 2 together
2x + 3y = 41....... Equation 1
2x + 6y = 68...... Equation 2
We Subtract Equation 1 from Equation 2, thereby eliminating x
3y = 27
y = 27/3
y = $9
Solving for x
2x + 3y = 41....... Equation 1
2x + 3(9) = 41
2x + 27 = 41
2x = 41 - 27
2x = 14
2x/2 = 14/2
x = $7
Therefore, the cost of each candy =
Cost of a pound of Jelly beans = x = $7
Cost of a pound of Gummy worms = y = $9
Parallelogram L M N O is shown. Diagonals are drawn from point M to point O and from point L to point N and intersect at point P. The length of L M is 22 centimeters and the length of M N is 18 centimeters. What is the perimeter of parallelogram LMNO?
Answer:
80 cm
Step-by-step explanation:
The perimeter of parallelogram LMNO
Is calculated using the formula
Perimeter = 2(a + b)
a = 18 cm
b = 22cm
Perimeter = 2(18 + 22)
= 2(40 cm)
= 80 cm
The perimeter of the parallelogram = 80 cm
Answer:
D. 80 cm

A triangle has side lengths of (10x+7y)(10x+7y) centimeters, (3x+3z)(3x+3z) centimeters, and (8z+10y)(8z+10y) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(109x²+140xy+18xz+49y²+160yz+73z²) centimeters
Step-by-step explanation:
perimeter = sum of all sides
side A = (10x+7y)(10x+7y)
= 100x² +70xy +70xy +49y²
= (100x² +140xy +49y²) centimeters
side B = (3x+3z)(3x+3z)
= 9x² +9xz +9xz +9z²
= (9x² +18xz +9z²) centimeters
side C = (8z+10y)(8z+10y)
= 64z² +80yz +80yz +100y²
= (64z² +160yz +100y²) centimeters
Perimeter = 100x²+140xy+49y² + 9x²+18xz+9z² + 64z²+160yz+100y²
collect like terms
= 100x² +9x²+140xy+18xz+49y²+160yz+9z²+64z²
= (109x²+140xy+18xz+49y²+160yz+73z²) centimeters

Brandon Brandon Drew the two congruent squares shown he divided one square into 2 congruent triangular parts he divided the other square into 2 congruent rectangular parts
Incomplete question: Options
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
(b) Each triangular part has an area that is greater than the area of each rectangular part.
(c) Each triangular part and each rectangular part represents 1/4 the area of one square
(d) Each rectangular part has an area that is greater than the area of each triangular part.
See attachment for squares
Answer:
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
Step-by-step explanation:
Given
See attachment
Required
Which statement is true
Before the division, the area of both squares is:
[tex]Area = l * w[/tex]
After the division:
The area of the triangle is:
[tex]Area = \frac{1}{2} * base * height[/tex]
[tex]A_1 = \frac{1}{2} * l * w[/tex]
Substitute Area for l * w
[tex]A_1 = \frac{1}{2} *Area[/tex]
This equals half the area of the square
The area of the rectangle is:
[tex]Area = length * width[/tex]
The length of the rectangle is now half the length of the original square.
So, we have:
[tex]A_2 = \frac{1}{2} l * w[/tex]
Substitute Area for l * w
[tex]A_2 = \frac{1}{2} *Area[/tex]
From the values of A1 and A2, we can conclude that (a) is true
What is the slope in the equation:
y= 3/4x - 1
Answer: the slope is 3/4.
y=mx+b and m is always the slope.
Answer:
the slope is 3/4
Step-by-step explanation:
y = mx + b
y = slopex + y intercept
y = 3/4x - 1
slope = 3/4
y intercept = -1

The volume of a square that is 2 feet on all sides is ?
Answer:
8 cubic feet
Step-by-step explanation:
2*2*2=8
Assuming you are talking about a cube, the volume would be the side^3. In this case you said all sides are 2 feet long then the volume would be:
2^3 ft^3 or 8 cubic feet!

Use FOIL to multiply.
(3x - 7)(x + 5)
Answer:
3x²+8x-35
Step-by-step explanation:
FOIL stands for:
First -> (3x-7)(x+5)
Outer -> (3x-7)(x+5)
Inner -> (3x-7)(x+5)
Last -> (3x-7)(x+5)
Following FOIL, we get:
(3x-7)(x+5)
(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)
3x²+15x-7x-35
3x²+8x-35
Therefore, the expanded form is 3x²+8x-35
