Which number sentence is true?
O A) 196 > 10
OB) 58 > 6.85
OC) -4/ > 25
OD) 8.45 x 102 > 845
Answer:
O A / OD
Step-by-step explanation:
196 is greater than 10
8.45×102 is greater than 845
-3x + 8 = 17 and 1 + 4x = -15
Answer:
1) x= -3
2) x=-4
Step-by-step explanation:
The first equation is :
-3x+8=17
solving for x
-3x=17-8 ------------by collecting like terms
-3x=9
Divide both sides by -3
-3x/-3=9/-3
x= -3
In the second equation
1+4x= -15
solving for x
4x=-15-1
4x = -16
x=-16/4
x= -4
Which graph I-IV matches with a?
Answer:
III
Step-by-step explanation:
At t = 0, x = 1.
At t = 0.5, x = 2.
At t = 1, x = 1.
The curve is symmetrical.
The graph that fits is III. x starts at 1, increases 2, then decreases at the same rate back to 1.

How do you do this question?
Answer:
(8√2) / 15
Step-by-step explanation:
A curve bounded by the y-axis is represented by in terms of dy;
[tex]\int \:x\:dt[/tex]
When the curve crosses the y-axis, x will be 0. In this case x is the function of t, so we have to solve for x(t) = 0;
0 = t^2 + 2t --- (1)
Solution(s) => t = 0, t = 2
dy = (1/2 * 1/√t)dt --- (2)
Our solutions (0, 2) are our limits. The area of the curve is in the form [tex]A\:=\:\int _b^a\:f\left(t\right)g'\left(t\right)dt[/tex] , so now let's introduce the limits of integration, x(t) and dy/dt. Remember, dy/dt = (1/2 * 1/√t) (second equation). 1/2 * 1/√t can be rewritten as 1/2 * t^(-1/2)....
[tex]A\:=\:\int _2^0\:\left(t^2-2t\right)\left(\frac{1}{2}t^{-\frac{1}{2}}\right)dt\\\\= \int _2^0\:\left(\frac{1}{2}t^{\frac{3}{2}}-t^{\frac{1}{2}}\right)dt\\\\= \left[\frac{t^{\frac{5}{2}}}{5}-\frac{2t^{\frac{3}{2}}}{3}\right]_2^0\\\\= 0\:-\:\left(\frac{4\sqrt{2}}{5}-\frac{4\sqrt{2}}{3}\right)\\\\= \frac{8\sqrt{2}}{15}[/tex]
Your solution is 8√2 / 15

Robert earned $10, which was 4 less than twice what Eric earned , How much money did Eric earn?
Answer:
Eric's earning is $7
Step-by-step explanation:
Given
Represent Robert's earnings with R and Eric's with E.
[tex]R = 10\\R = 2E - 4[/tex]
Required
What is the value of E?
Substitute 10 for R in the second equation.
[tex]10 = 2E - 4[/tex]
Solve for 2E
[tex]2E = 10 + 4[/tex]
[tex]2E = 14[/tex]
Solve for E
[tex]E = 14/2[/tex]
[tex]E = 7[/tex]
Eric's earning is $7
question 7 i mark as brainliest
Which expression is equivalent to (4 - 7)(2x - 1)?
The equivalent expression to [tex](4-7)(2x-1)[/tex] is [tex]-6x+3[/tex]
First, you multiply the binomials using the multiplying binomial that you are used to. I like to use the box method.
Multiply 4 by 2x and -1 and multiply -7 by 2x and -1
[tex]8x-14x-4+7[/tex]
Then, add like terms.
[tex]-6x+3[/tex]

The expression $1.75 + $0.15x can be used to find Mr. Thompson's cost for
making x dozen cookies. How much does it cost Mr. Thompson to make 25
dozen cookies? {Write an equation.} *and also ( solve and equation).
Answer:
Step-by-step explanation:
3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3
Plug x = 3 in (2):
2(3) + y = 5
6 + y = 5
y = 5-6
y = -1
Thus, x = 3 and y = -1
