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:
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
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
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

(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
Isiah earned 96 points on his math test this is 11 more points than the number of points he earned on his history test. Write and solve an addition equation to find the number of points isiah earned on his test
Answer:
96-11
Step-by-step explanation:
I am not sure how to make an addition equation? normally you would just subtract 11 to get the result of the history test because he got 11 less points then he did on his maths test which is 96!

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

Identify the pair of figures in which the second figure is a translation of the first figure.
C.

The answer is C because unlike the other shapes C wasn't altered in anyway. It just move, which is what a translation is just moving a shape and not altering it in anyway.
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!

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 1) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 1 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - nine halfs plus twelve = thirty-three halfs.

Step-by-step explanation:
The sum of 4[tex]\frac{1}{2}[/tex] and 8[tex]\frac{3}{14}[/tex] is 12[tex]\frac{5}{7}[/tex].
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Let the required number be n.
According to the question,
the sum of 4[tex]\frac{1}{2}[/tex] and n is equal to 12[tex]\frac{5}{7}[/tex].
In numeric form,
4[tex]\frac{1}{2}[/tex] + n = 12[tex]\frac{5}{7}[/tex]
Simplifying,
9/2 + n = 89/7
Substituting constant to term one side,
n = 89/7 - 9/2
n = 115/14
n = 8[tex]\frac{3}{14}[/tex]
Therefore, the number is 8[tex]\frac{3}{14}[/tex].

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
A mosaic tile is shown below. Dan wants to cover a 600-square-inches area. How many mosaic tiles does Dan need?
Answer:
B. 30
Step-by-step explanation:
The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a and b represent the length of its plane sides, and h is the height.
Area of a mosaic tile = [tex]\frac{1}{2}[/tex](4 + 6) 4
= 10 x 2
Area of a mosaic tile = 20 square inches.
But, Dan wants to cover a 600 square inch area.
So that the number of tiles needed = [tex]\frac{600}{20}[/tex]
= 30
The number of mosaic tiles needed by Dan is 30.

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
