8x-2 - -4x2< 4+10
-16+8<4+10
-8<14
9514 1404 393
Answer:
8×(−2)−(−4)^2 < 36÷9+2×5
Step-by-step explanation:
The left side expression evaluates as ...
8×(−2)−(−4)^2
= 8×(−2) − 16
= -16 -16
= -32
__
The right side expression evaluates as ...
36÷9+2×5
= 4 + 10
= 14
__
It should be no mystery that any negative number is less than any positive number:
-32 < 14
8×(−2)−(−4)^2 < 36÷9+2×5 . . . . . . . . "less than" symbol is required
What is the length of the missing side?
9514 1404 393
Answer:
10
Step-by-step explanation:
The Pythagorean theorem tells you the relationships of sides in a right triangle is ...
a² + b² = c² . . . . . . where 'a' and 'b' are the legs, and 'c' is the hypotenuse
6² +8² = c²
36 +64 = c² = 100
c = √100 = 10
The length of the hypotenuse is 10.
_____
Additional comment
The ratio of the leg lengths is 8/6 = 4/3. The only right triangle with legs in the ratio 4/3 has the relationship ...
hypotenuse : long leg : short leg = 5 : 4 : 3
If you multiply these numbers by 2, you see they correspond to the side lengths in this triangle. Your familiarity with a 3-4-5 right triangle can let you write down the answer immediately.

Which equation represents the line through (0,0) and (2,5)?
A. y= 5x
B. y= 2x
C. y= 5/2x
D. y= 2/5x
The equation of the line passing through (0,0) and (2,5) will be y = ( 5 / 2 )x. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line is:-
y = mx + c
Given that the line passes through (0,0) and (2,5). to calculate the equation we need to calculate the slope of the line.
m = ( y₂ - y₁) / ( x₂ - x₁ )
m = ( 5 - 0 ) / ( 2 - 0 )
m = ( 5 / 2 )
y = ( 5 / 2)x + c
0 = 0 + c
c = 0
Y = ( 5 / 2)x
Therefore, the equation of the line passing through (0,0) and (2,5) will be y = ( 5 / 2 )x. The correct option is C.

Jared filled 6 bowls with strawberries he put 8 strawberries in each bowl how many strawberries did Jared use
Answer:
48 Strawberries
Step-by-step explanation:
To solve this you multiply 6 times 8 because if there are 6 bowls and you put 8 in each, you are going to get 8+8+8+8+8+8 which is the same as 6 times 8. Hope this helps!

Step-by-step explanation:
just think a little bit.
congruent rectangles means they are all of equal size.
so, the sizes of all of these rectangles are 3×4.
therefore, the area of each one is 3×4 = 12 cm².
the total surface area (without the top
and bottom stars) is the sum of the areas of all rectangles.
how many rectangles are there ?
well, every "arm" of the star has 2 rectangle sides. and there are 5 "arms". so, there are 2×5 = 10 rectangles.
now it is really easy, right ?
we have 10 rectangles, each one with an area of 12 cm².
so the total surface area (without the star bases) is
12×10 = 120 cm²
The sales of a certain product after an initial release can be found by the equation

Make a table of values, graph the function and use the graph to estimate the sales
12 weeks after release.
about $586
about $93
about $93,000
about $586,000
Answer:
It's c
Step-by-step explanation:
The sales after 12 weeks is about $93. Therefore, option B is the correct answer.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is s=12√4t+10, where s represents the total sales in thousands) and t represents the time in weeks after release.
The sales 12 weeks after release is
s=12√4×12+10
s=12√48+10
s=93.13
s=93
Therefore, option B is the correct answer.

Write the equation of the line in fully simplified slope intercept form
Answer:
y = x + 8
Step-by-step explanation:
It is y = 1/1x + 8, but we don't put the one if it's at the botton. So, y = 1x + 8, but, when a one is in front of the x, we don't put it either. The answer is
y = x + 8
The y-intercept is where the line "touches" the y-intercept, in this case, 8.
The slope is how many times you go up-down, and to side from point to pint, in this case 1/1.
Makes sense? If so, hope this helps!
Answer:
y = -1x + 8 or y = -x + 8 (both are same)
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
4 - 6 / 4 - 2 = -2/2 = -1
m = -1
b = y-intercept
b = 8
y = mx + b
y = -1x + 8
y = -x + 8
