Answer:
b = 16
Step-by-step explanation:
16*x + b*x + 4 = 0
Solving for x we get:
x₁,₂ = - b ± √ b² - 4*a*c ] / 2*a (1)
If we take a look to the square root
√ b² - 4*4*16 = √ b² - 256
if we make √ b² - 256 = 0
b² = 256 ⇒ b = 16
Then equation (1) becomes:
x₁,₂ = ( - 16 ± 0 ) / 32
x = - 1/2
1) Which pair of triangles is congruent by Side - Side - Side? *
Please do all of them and don't answer if you don't know thanks in advance :)
best answer will get brainliest and multiple thanks on some of your other answers and this one
Answer:
The fourth pair of triangles.
Step-by-step explanation:
Looking at the diagram for the fourth pair of triangles, we see that two pairs of sides have been marked as having the same length, and the remaining side is shared by the two triangles, hence guaranteeing that side's congruence. Therefore, the fourth pair of triangles is congruent by SSS.
The first pair of triangles are congruent by ASA, due to the middle pair of angles being congruent (vert. opp. ∠s), hence providing the condition for SAS.
The second pair of triangles should be SAS, also known as Side - Angle - Side, due to two angles and one side being marked as congruent, and those two angles surrounding the side marked as congruent.
The third pair of triangles should be SAS, due to them sharing a common side and a pair of sides marked congruent, surrounding the right angle. The reason why it is not RHS is because the pair of hypotenuses are not congruent, hence not fulfilling the condition of Right Angle - Hypotenuse (here!) - Side.
Hope this helped!

PLEASE HURRY Find the midpoints between points C (7, -9) and D (3, 5).
Answer:
(5,-2)
Step-by-step explanation:
Midpoint formula
If we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x₃,y₃). The midpoint calculator will solve this instantaneously if you input the coordinates. Follow the steps above if calculating by hand.
For small numbers, it's easy to calculate the midpoint by hand, but with larger and decimal values, the calculator is the simplest and most convenient way to calculate the midpoint.
Answer:
Midpoint=(5,−2)Step-by-step explanation:
Midpoint formula
m=((x1+x2)/2,(y1+y2)/2
so lets plug in
((7+3)/2,(-9+5)/2)
(10/2),(-4/2)
(5,−2)

Start a system of equations for X plus 3Y equals 17 and 3X plus 2Y equals 13
Answer:
Step-by-step explanation:
a system of equations:
x+3y=17
3x+2y=13
Which equation has no solution?
A. 13y + 2 - 2y = 10y + 3 - y
B. 9(3y + 7) - 2 = 3(-9y + 9)
C. 32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1
D. 5(2.2y + 3.4) = 5(y - 2) + 6y
Answer:
D
Step-by-step explanation:
Option D is the only equation where the y-term gets eliminated upon simplifying
11y + 17 = 5y - 10 + 6y
11y + 17 ≠ 11y - 10
The dance committee of Pine Bluff Middle School earns \$72$72dollar sign, 72 from a bake sale and will earn $4 dollar sign, 4 for each ticket they sell to the Spring Fling dance. The dance will cost $400. Write an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
Answer:
t > 82
Step-by-step explanation:
Given that,
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.
The dance will cost $400.
We need to find an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
The committee earns $4 for each ticket. It means they will earn $4t.
$72 is constant as they earn it from bake sale.
The total earning must be greayer than $400.
ATQ,
4t + 72 > 400
We can solve the above inequality to find the value of t.
4t > 328
t > 82
Hence, the committee could sell more than 82 tickets to have money left over after they pay for this year's dance.

The computation of the new price of the t-shirt is shown below
= Price of the t-shirt × (1 + increased percentage)
= $23 × (1 + 0.08)
= $23 × 1.08
= $24.84

Coachella Valley of California the elevation is 215 feet below sea level.
Clara wrote this elevation as -215 feet.
Is Clara's response reasonable? Explain the given elevation with respect to its relationship to 0.
Answer:
Yes. Her answer is reasonable.

daniel has read 40% of a book. He has more 36 pages to finish. How many pages are there in the book?
Answer:
60 Pages.
Step-by-step explanation:
Using the given information, we can figure out that the remaining 36 pages are 60% of the book.
This is because 100% (whole book) - 40% (what you already read)= 60%= the remaining 36 pages
We can set up a problem to find 36 pages out of how many total pages is equal to 60%
(36/x) x 100 = 60%
=3600/60
=60 pages.
We can check our work by saying checking that 40% of 60 is 24, and 24+36 is 60 pages.

A. 0.003%
B. 0.03%
C. 3%
D. 30%
Answer:
D, 30%
Step-by-step explanation:
you move the decimal point twice to the right
Answer:
D. 30%
Step-by-step explanation:
This is the answer because:
1) When you convert decimals to percents, you have to remember the two main decimal places:
0.00 = The hundredths place
0.00 = The tenths place
2) Whenever there is a decimal that is in the hundredths place, it will equal a one digit percent. For example, 0.07 = 7%.
3) Whenever there is a decimal that is in the tentsh place, it will equal a two digit number. For example, 0.3 = 30%.
4) Another way to solve it is to convert the decimal to a percentage by multiplying the decimal by 100 .
Therefore, the answer is 30%.
Hope this helps! :D
