pls answer fast!
Answers
Answer:
C. All positive solutions
Step-by-step explanation:
We can see that the solutions (or points that intercept the x-axis) are at 0,1 and 0,2. We can simplify this to just 1,2 if you would like, but nevertheless all x-intercepts are positive.
x = 1 and x = 2 are the solutions of the parabola shown.
All whole number and positive solutions.
Options C and D are correct.
How do you find the opening of a parabola?There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
When we are looking for a solution to a graphical function f(x), we basically mean the x-intercepts of the graph.
The place where the graph cuts/crosses the x-axis are the solutions of the graph. The y point will always be 0 at those designated x values.
Looking at the graph, we see that:
x = 1 and x = 2
are the solutions of the parabola shown.
All whole number and positive solutions.
Options C and D are correct.

Taylor emptied out her change jar to buy a new soccer ball for practice. The jar contained 128 coins consisting of quarters and dimes that totaled $25.10. Which system of equations could be used to determine how many quarters, q, and how many dimes, d, Taylor had in her change jar?
Answers
Answer:
.25q+.10d=25.10
q+d=128
Step-by-step explanation:
Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.
q+d=128
25q+10d=2510
These are the system of equations. To solve it, we do this:
q=128-d
25(128-d)+10d=2510
3200-25d+10d=2510
15d=690
d=46
q=128-46=82

The cube volume is 1000cm find the all face area
A. 200cm
B. 300cm
C. 500cm
D. 600cm
Answers
Answer:
D. 600 [tex]cm^{2}[/tex]
Step-by-step explanation:
Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]
So, the side length is 10 cm
Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length
so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]
6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]
So the answer is D. 600 cm (it should have a little superscript 2 next to it)

Answers
Answer:
C: √74
Step-by-step explanation:
We have to use the Pythagorean theorem to answer this (a² + b² + c²). We have a and b so all we have to do is square 5 and 7 (a and b) so we get a² b², then we add this to get c² as stated by the Pythagorean theorem. So, 7² (7 x 7) is 49, and 5² (5 x 5) is 25. 25+49 (a² + b²) is 74 (c²). So the square root of this would be the absolute length of the hypotenuse because this is the hypotenuse squared. Meaning that the answer would be √74 (square root of 74)
Darnell is trying to understand the Pythagorean Theorem by drawing a few triangles. He found that 1² + 1² = (√2)² is accurate. Which statement is true about Darnell’s triangle?
A. The triangle is not a right triangle because the lengths of its sides measure the same.
B. The triangle is not a right triangle because the hypotenuse is shorter that the lengths of its sides.
C. The triangle is a right triangle, the lengths of its sides are 1 and √2 with a hypotenuse of 1.
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
PLEASE HELP ASAP!!!!
Answers
Answer:
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
Step-by-step explanation:
The Pythagorean Theorem is modeled by a² + b² = c².
c represents the hypotenuse and a and b represent the other two sides.
The Pythagorean Theorem can only be applied to right triangles.

70% of x is 63. Write an equation that represents this statement.
Answers
answer:
70/100x = 63
step-by-step explanation:
so first we must turn 70% into a fraction-
70/100
and since we know that 63 is the answer
that must mean that x is being multiplied by 70/100
therefore making the equation 70/100x=63

Answers
Answer:
see below
Step-by-step explanation:
a. -11r ≥ 220
Divide both sides by -11 to isolate r.
r ≥ -20
b.
-8 ≤ -7 + (x/10)
Add 7 to both sides.
-1 ≤ x/10
Multiply both sides by 10 to cancel out the denominator of x.
-10 ≤ x
c. -1 - 6(5q - 2) ≥ -139
Distribute the -6 across the parentheses.
-1 - 30q + 12 ≥ -139
Combine like terms on the left side.
-30q + 11 ≥ -139
Subtract 11 from both sides.
-30q ≥ -150
Divide both sides by -30 to isolate q.
q ≥ 5
Hope this helps!
divide both sides by -11
since both sides are divided, flip the sign
r<=-20
r is less than or equal to negative twenty
