Answer:
The roots of the equation is real and repeated
Step-by-step explanation:
Here, we want to describe the nature of the roots of the given quadratic equation
To get the nature of the roots, we find the discriminant of the equation
The discriminant is;
b^2 - 4ac
In this case, b = -28 , a = 49 and c = 4
The discriminant is thus;
-28^2 - 4(49)(4)
= 784 - 784 = 0
Since the discriminant is zero, this means that the quadratic equation has real roots which are the same
2x + 5 greater then or equal to -1
Explain how you determine the sign of your answer when you raise a negative base to a power.
Answer:
If the power is even number sign will be positive.
If the power is odd number sign will be negative.
Example:
-2² = -2 * -2 = 4
-2³ = -2 * -2 * -2 = 4 * -2 = -8

Write addition sentences (expression) where the sum is
zero.
Write a recursive rule for the sequence –17.-11, -5, 1, ...
show complete working format please
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6
A recursive rule allows a term to be found by adding d to the previous term, thus
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6 with a₁ = - 17
(4,8) and (-2,16). how do you find the y-intercept
Answer:
Look at explanation
Step-by-step explanation:
All you have to do is plot these points on a graph. Then make a straight line through them.
The y-intercept is the point of the line that passes through y, the vertical line.
The example shows that the y-inercept is (0, 3)

Answer:
75 degrees
Step-by-step explanation:
Straight angles are 180, so since we already know one side (105 degrees). This means that 105+x=180
If you solve it you get 75
Ronnie made 5 pies for New Year's Day. Some of his family members are allergic to gluten, so he bought gluten-free flour for all of the pies. For each piecrust, he used 2 cups of flour. Health Mart sold bags with 4 cups of gluten-free flour for $12. How much did Ronnie spend on the gluten-free flour so that he had enough for the crusts?
Answer:
He spent $24 dollars
Step-by-step explanation:
Each of the piecrusts had 2 cup of flour he has 5 pies so all pies altogether equally 10 cups so he buys 2 bags for $24 dollars
Step-by-step explanation:
Number of gluten-free flour used for 5 pies= 2×5= 10 cups
cost of 4 cups of gluten-free flour = $12
cost of 1 cup = 12/4 = $3
Then,
cost of 10 cups of gluten-free flour = 3×10
= $30

A package of nuts weights 3/4 of a pound. One serving size is 1/8 of a pound, how many servings in the package?
Answer: 6 servings
Step-by-step explanation:
One serving is 1/8 of a pound.
One package is 3/4 of a pound.
The number of servings therefore will be the number of times that 1/8 can go into 3/4.
= (3/4) / (1/8)
= (3/4) * (8/1)
= 6 servings
Reflect the point (-7, -9) across the x-axis: Then
Reflect the point (-7, -9) across the y-axis:
Step-by-step explanation:
Reflecting across the x axis will result in a sign change for. the y component, therefore (-7,-9) becomes (-7,9)
Reflecting across the y axis will result in a sign change for the x component, therefore (-7,-9) becomes (7,-9)

Trisha’s parents bought a new house that has 2,255 square feet.
The price per square foot was $98. How much did they pay for the house? Enter your answer in the box.
Answer:$220,290
Step-by-step explanation:
2,255 multiplied by 98 is 220,290
The total cost of Trisha’s parents new house is $220990.
Given that, Trisha’s parents bought a new house that has 2,255 square feet.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The price per square foot was $98.
So, the total cost of house = Number of square feet × The price per square foot
= 2,255 × 98
= $220990
Therefore, the total cost of Trisha’s parents new house is $220990.
