1. y = x² + 2
2. y = 2x - 10
3. y= 9 - 2x²
4. y = 2x + 2
5. y = 3x² + x² + 2
9514 1404 393
Answer:
yesnoyesnoyesStep-by-step explanation:
The function is quadratic if the highest degree of any term is 2. Equations 2 and 4 have degree 1, so are linear (not quadratic) functions. Equations 1, 3, and 5 have terms of degree 2 (at most), so are quadratic functions.
_____
We assume that two terms of degree 2 in equation 5 is intentional. If one of those is supposed to be of degree 3 (or more), then that function is not quadratic.

how to solve 1.2x+1.4y=2.7 and 0.4x-0.3y=0.9 in substitution
Answer:
x=0.8712, y=1.1818
Step-by-step explanation:
1.2x+1.4y=2.7 --(1)
0.4x-0.3y=0.9--(2)
1.2x=2.7-1.4y
x=(2.7-1.4y) / 1.2 --(3)
substitute (3) in (2)
[tex]0.4(2.7-1.4y) / 1.2 -0.3y=0.9[/tex]
[tex](1.8 - 0.56y) \frac{1}{3} - 0.3y = 0.9[/tex]
times both sides with 1/3
[tex] \frac{1}{3} (1.08 - 0.56y( \frac{1}{3} ) - 0.3y = 0.9)[/tex]
1.08-0.3=0.56y+0.1y
0.78=0.66y
y=1.1818
substitute y in (3)
x=2.7-1.4(1.1818) /1.2
x=0.8712

PLEASE MARK AS BRAINLIEST!!!!!Katie memorized 40 multiplication facts last week. This week she memorized 56 multiplication facts. What is her percent of increase for memorizing multiplication facts this week? o 22.4 % O 71.4 % O 40% O 140%
The percent of increase in Katie's memorization of multiplication facts this week is 40%. Option C
To calculate the percent of increase for Katie's memorization of multiplication facts this week, we need to find the difference between the number of facts she memorized last week and this week, and then express that difference as a percentage of the original value.
Number of multiplication facts memorized last week: 40
Number of multiplication facts memorized this week: 56
To find the difference in the number of facts, we subtract the number memorized last week from the number memorized this week:
56 - 40 = 16
The difference is 16.
To calculate the percent of increase, we divide the difference by the original value and multiply by 100:
(16 / 40) * 100 = 40
The percent of increase in Katie's memorization of multiplication facts this week is 40%.
Therefore, the correct answer is C) 40%.

what is the slope intercept form of (4,-3) and (2,1)
Step 1: Find the Slope
Slope Formula: (y2 - y1) / (x2 - x1)
Point 1 = (4, -3)
Point 2 = (2, 1)
Slope = (1 - - 3) / (2 - 4) = (4) / (-2) = -2
Step 2: Find the Y-Intercept
Plug in the slope and one of the points into slope-intercept form and solve for b.
Slope-Intercept Form: y = mx + b
1 = -2(2) + b
1 = -4 + b
b = 5
Step 3: Put it all together
Plug in the slope and y-intercept into slope-intercept form.
Slope-Intercept Form: y = mx + b
y = -2x + 5

Explain or show work to prove that the following equation is true.6 x 8 = 3 x 2 x 2 x 2 x 2
Answer:
see explanation
Step-by-step explanation:
To prove the equation id true, solve both sides and if they are equal then the equation is true.
left side = 6 × 8 = 48
right side = 3 × 2 × 2 × 2 × 2
= 6 × 2 × 2 × 2
= 12 × 2 × 2
= 24 × 2
= = 48
Since both sides are equal then the equation is true
